I ran "MinGW Installation Manager" and it installed gfortran v 6.3.0-1 That version appears to work fine for my namelist array problem. I'm not sure how to upgrade beyond 6.3.0-1 to the versions mentioned in the "known to work" section (6.4.1, 7.3.1, 8.1.1, 9.0) but my immediate problem is certainly fixed.

So this I suggest: main.cpp:11:25: error: cannot pass ‘const int’ by non-const ‘int&’ Or with the "reference" word: main.cpp:11:25: error: cannot pass ‘const int’ by non-const ‘int&’ reference.

First, it zeroes out the entire array even though only a small part of it is used. Worse, (and ironically) because it eliminates the store to a[3] as dead early on (in fre1) and before the strlen pass runs, the strlen optimization isn't performed, and so the entire dead body of the function isn't eliminated. Since unnecessarily zeroing-out storage just before storing strings in it is common practice, detecting and handling it could lead to significant improvements. The solution for the missing strlen optimization in this case could be as simple as enhancing the strlen pass to track not just string lengths but also sizes of zeroed-out blocks of storage used for strings. $ cat c.c && gcc -O2 -S -Wall -Wextra -fdump-tree-optimized=/dev/stdout c.c void f (void) { char a[4096]; __builtin_memcpy (a, "123", 3); a[3] = 0; if (__builtin_strlen (a) != 3) // folded __builtin_abort (); } void g (void) { char a[4096] = ""; // all bytes zeroed out __builtin_memcpy (a, "123", 3); a[3] = 0; // eliminated if (__builtin_strlen (a) != 3) // not folded __builtin_abort (); } ;; Function f (f, funcdef_no=0, decl_uid=1956, cgraph_uid=0, symbol_order=0) f () { [local count: 1073741825]: return; } ;; Function g (g, funcdef_no=1, decl_uid=1960, cgraph_uid=1, symbol_order=1) g () { char a[4096]; long unsigned int _1; [local count: 1073741825]: a = ""; __builtin_memcpy (&a, "123", 3); _1 = __builtin_strlen (&a); if (_1 != 3) goto ; [0.00%] else goto ; [99.96%] [count: 0]: __builtin_abort (); [local count: 1073312327]: a ={v} {CLOBBER}; return; } >From gcc-bugs-return-606653-listarch-gcc-bugs=gcc.gnu.org@gcc.gnu.org Thu Jun 07 01:10:19 2018 Return-Path: Delivered-To: listarch-gcc-bugs@gcc.gnu.org Received: (qmail 44669 invoked by alias); 7 Jun 2018 01:10:19 -0000 Mailing-List: contact gcc-bugs-help@gcc.gnu.org; run by ezmlm Precedence: bulk List-Id: List-Archive: List-Post: List-Help: Sender: gcc-bugs-owner@gcc.gnu.org Delivered-To: mailing list gcc-bugs@gcc.gnu.org Received: (qmail 44546 invoked by uid 48); 7 Jun 2018 01:10:14 -0000 From: "paul.hua.gm at gmail dot com" To: gcc-bugs@gcc.gnu.org Subject: [Bug target/86067] [MIPS] ICE: scal-to-vec1.c:86:1: error: unrecognizable insn with -march=loongson3a Date: Thu, 07 Jun 2018 01:10:00 -0000 X-Bugzilla-Reason: CC X-Bugzilla-Type: changed X-Bugzilla-Watch-Reason: None X-Bugzilla-Product: gcc X-Bugzilla-Component: target X-Bugzilla-Version: unknown X-Bugzilla-Keywords: X-Bugzilla-Severity: normal X-Bugzilla-Who: paul.hua.gm at gmail dot com X-Bugzilla-Status: WAITING X-Bugzilla-Resolution: X-Bugzilla-Priority: P3 X-Bugzilla-Assigned-To: unassigned at gcc dot gnu.org X-Bugzilla-Target-Milestone: --- X-Bugzilla-Flags: X-Bugzilla-Changed-Fields: Message-ID: In-Reply-To: References: Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable X-Bugzilla-URL: http://gcc.gnu.org/bugzilla/ Auto-Submitted: auto-generated MIME-Version: 1.0 X-SW-Source: 2018-06/txt/msg00448.txt.bz2 Content-length: 262 https://gcc.gnu.org/bugzilla/show_bug.cgi?id=86067 --- Comment #2 from Paul Hua --- (In reply to Richard Biener from comment #1) > Which GCC version did you use? the trunk version (r261200) It's also ICEed on gcc-7 and gcc-8. >From gcc-bugs-return-606654-listarch-gcc-bugs=gcc.gnu.org@gcc.gnu.org Thu Jun 07 01:26:21 2018 Return-Path: Delivered-To: listarch-gcc-bugs@gcc.gnu.org Received: (qmail 7957 invoked by alias); 7 Jun 2018 01:26:20 -0000 Mailing-List: contact gcc-bugs-help@gcc.gnu.org; run by ezmlm Precedence: bulk List-Id: List-Archive: List-Post: List-Help: Sender: gcc-bugs-owner@gcc.gnu.org Delivered-To: mailing list gcc-bugs@gcc.gnu.org Received: (qmail 7811 invoked by uid 48); 7 Jun 2018 01:26:15 -0000 From: "jvdelisle at gcc dot gnu.org" To: gcc-bugs@gcc.gnu.org Subject: [Bug libfortran/86070] [7 regression] gfortran.dg/fmt_zero_digits.f90 segmentation fault starting with r261077 Date: Thu, 07 Jun 2018 01:26:00 -0000 X-Bugzilla-Reason: CC X-Bugzilla-Type: changed X-Bugzilla-Watch-Reason: None X-Bugzilla-Product: gcc X-Bugzilla-Component: libfortran X-Bugzilla-Version: 7.3.1 X-Bugzilla-Keywords: X-Bugzilla-Severity: normal X-Bugzilla-Who: jvdelisle at gcc dot gnu.org X-Bugzilla-Status: ASSIGNED X-Bugzilla-Resolution: X-Bugzilla-Priority: P3 X-Bugzilla-Assigned-To: jvdelisle at gcc dot gnu.org X-Bugzilla-Target-Milestone: --- X-Bugzilla-Flags: X-Bugzilla-Changed-Fields: bug_status cf_reconfirmed_on assigned_to everconfirmed Message-ID: In-Reply-To: References: Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable X-Bugzilla-URL: http://gcc.gnu.org/bugzilla/ Auto-Submitted: auto-generated MIME-Version: 1.0 X-SW-Source: 2018-06/txt/msg00449.txt.bz2 Content-length: 672 https://gcc.gnu.org/bugzilla/show_bug.cgi?id=86070 Jerry DeLisle changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |ASSIGNED Last reconfirmed| |2018-06-07 Assignee|unassigned at gcc dot gnu.org |jvdelisle at gcc dot gnu.org Ever confirmed|0 |1 --- Comment #1 from Jerry DeLisle --- Mine, not sure why that patch would break it.

We might want to revisit the fact that we punt on this by ICEing with -fchecking... Getting more testcase for this is nice though. Getting some brains inventing patterns we could detect to code-generate expressions like if (((-P_9 + 18446744073709551615) % 18446744073709551616) + P_1 <= 18446744073709551614 || ((-P_9 + 18446744073709551615) % 18446744073709551616) + P_1 >= 18446744073709551616) with a data type that cannot represent the above would be nice as well. Note that even a simple P_9 + P_9 might not be representable but wrap/overflow in the type we code-generate in (which is fixed! to be the "largest" integer type the target supports). So in reality some range information is needed which we _may_ be able to recover.

What arm subarchitecture are you creating code for? On x86 with -m32 the 'size' loop isn't recognized as memset at the GIMPLE level (it isn't a memset after all) and we expand the 'pro' loop as memset call but not the 'rem' loop. Note that pro seems to be MAX(size, & 3) so it isn't really <= 3. Thus, x86 is working fine but arm isn't. >From gcc-bugs-return-606678-listarch-gcc-bugs=gcc.gnu.org@gcc.gnu.org Thu Jun 07 08:27:10 2018 Return-Path: Delivered-To: listarch-gcc-bugs@gcc.gnu.org Received: (qmail 43927 invoked by alias); 7 Jun 2018 08:27:10 -0000 Mailing-List: contact gcc-bugs-help@gcc.gnu.org; run by ezmlm Precedence: bulk List-Id: List-Archive: List-Post: List-Help: Sender: gcc-bugs-owner@gcc.gnu.org Delivered-To: mailing list gcc-bugs@gcc.gnu.org Received: (qmail 43820 invoked by uid 48); 7 Jun 2018 08:27:04 -0000 From: "rguenth at gcc dot gnu.org" To: gcc-bugs@gcc.gnu.org Subject: [Bug tree-optimization/86072] Poor codegen with atomics Date: Thu, 07 Jun 2018 08:27:00 -0000 X-Bugzilla-Reason: CC X-Bugzilla-Type: changed X-Bugzilla-Watch-Reason: None X-Bugzilla-Product: gcc X-Bugzilla-Component: tree-optimization X-Bugzilla-Version: 9.0 X-Bugzilla-Keywords: missed-optimization X-Bugzilla-Severity: enhancement X-Bugzilla-Who: rguenth at gcc dot gnu.org X-Bugzilla-Status: NEW X-Bugzilla-Resolution: X-Bugzilla-Priority: P3 X-Bugzilla-Assigned-To: unassigned at gcc dot gnu.org X-Bugzilla-Target-Milestone: --- X-Bugzilla-Flags: X-Bugzilla-Changed-Fields: bug_status cf_reconfirmed_on everconfirmed Message-ID: In-Reply-To: References: Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable X-Bugzilla-URL: http://gcc.gnu.org/bugzilla/ Auto-Submitted: auto-generated MIME-Version: 1.0 X-SW-Source: 2018-06/txt/msg00473.txt.bz2 Content-length: 1233 https://gcc.gnu.org/bugzilla/show_bug.cgi?id=86072 Richard Biener changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |NEW Last reconfirmed| |2018-06-07 Ever confirmed|0 |1 --- Comment #2 from Richard Biener --- Andrew is right. Still confirmed. Somebody has to decide if it's worth optimizing them and has to sit down and exactly specify what kind of optimizations are valid. I guess it's worth optimizing them if these cases appear in real-world code (and then we'd like to see examples). As for validity not optimizing them leads to (wanted/required) side-effects like being a barrier for a lot of compiler optimizations. Which may mor may not be designed that way. I'm sitting on patches teaching points-to about atomics, specifically making them not escape points or uses/clobbers for all memory. Esp. the latter I'm not sure is a good idea to improve, because there's nothing in the compiler making atomics "special", they are just modeled as function calls. >From gcc-bugs-return-606679-listarch-gcc-bugs=gcc.gnu.org@gcc.gnu.org Thu Jun 07 08:28:16 2018 Return-Path: Delivered-To: listarch-gcc-bugs@gcc.gnu.org Received: (qmail 46198 invoked by alias);

This is a clear violation of the standard's translation phase 2, making it impossible to e.g. preprocess something like https://xenbits.xen.org/gitweb/?p=xen.git;a=blob;f=xen/include/asm-x86/alternative-asm.h;h=0b6151634a01e9662ae4100dcaf3c0736885eb87;hb=refs/heads/staging into code usable by the .s files produced by the compiler. >From gcc-bugs-return-606682-listarch-gcc-bugs=gcc.gnu.org@gcc.gnu.org Thu Jun 07 08:56:47 2018 Return-Path: Delivered-To: listarch-gcc-bugs@gcc.gnu.org Received: (qmail 104902 invoked by alias); 7 Jun 2018 08:56:47 -0000 Mailing-List: contact gcc-bugs-help@gcc.gnu.org; run by ezmlm Precedence: bulk List-Id: List-Archive: List-Post: List-Help: Sender: gcc-bugs-owner@gcc.gnu.org Delivered-To: mailing list gcc-bugs@gcc.gnu.org Received: (qmail 104609 invoked by uid 48); 7 Jun 2018 08:56:42 -0000 From: "jbeulich at novell dot com" To: gcc-bugs@gcc.gnu.org Subject: [Bug preprocessor/86079] preprocessor fails to splice lines Date: Thu, 07 Jun 2018 08:56:00 -0000 X-Bugzilla-Reason: CC X-Bugzilla-Type: changed X-Bugzilla-Watch-Reason: None X-Bugzilla-Product: gcc X-Bugzilla-Component: preprocessor X-Bugzilla-Version: 8.1.0 X-Bugzilla-Keywords: X-Bugzilla-Severity: normal X-Bugzilla-Who: jbeulich at novell dot com X-Bugzilla-Status: UNCONFIRMED X-Bugzilla-Resolution: X-Bugzilla-Priority: P3 X-Bugzilla-Assigned-To: unassigned at gcc dot gnu.org X-Bugzilla-Target-Milestone: --- X-Bugzilla-Flags: X-Bugzilla-Changed-Fields: Message-ID: In-Reply-To: References: Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable X-Bugzilla-URL: http://gcc.gnu.org/bugzilla/ Auto-Submitted: auto-generated MIME-Version: 1.0 X-SW-Source: 2018-06/txt/msg00477.txt.bz2 Content-length: 150 https://gcc.gnu.org/bugzilla/show_bug.cgi?id=86079 --- Comment #1 from jbeulich at novell dot com --- Interesting - with -P the problem goes away. >From gcc-bugs-return-606683-listarch-gcc-bugs=gcc.gnu.org@gcc.gnu.org Thu Jun 07 09:02:37 2018 Return-Path: Delivered-To: listarch-gcc-bugs@gcc.gnu.org Received: (qmail 15076 invoked by alias); 7 Jun 2018 09:02:37 -0000 Mailing-List: contact gcc-bugs-help@gcc.gnu.org; run by ezmlm Precedence: bulk List-Id: List-Archive: List-Post: List-Help: Sender: gcc-bugs-owner@gcc.gnu.org Delivered-To: mailing list gcc-bugs@gcc.gnu.org Received: (qmail 14912 invoked by uid 48); 7 Jun 2018 09:02:32 -0000 From: "schwab@linux-m68k.org" To: gcc-bugs@gcc.gnu.org Subject: [Bug preprocessor/86079] preprocessor fails to splice lines Date: Thu, 07 Jun 2018 09:02:00 -0000 X-Bugzilla-Reason: CC X-Bugzilla-Type: changed X-Bugzilla-Watch-Reason: None X-Bugzilla-Product: gcc X-Bugzilla-Component: preprocessor X-Bugzilla-Version: 8.1.0 X-Bugzilla-Keywords: X-Bugzilla-Severity: normal X-Bugzilla-Who: schwab@linux-m68k.org X-Bugzilla-Status: UNCONFIRMED X-Bugzilla-Resolution: X-Bugzilla-Priority: P3 X-Bugzilla-Assigned-To: unassigned at gcc dot gnu.org X-Bugzilla-Target-Milestone: --- X-Bugzilla-Flags: X-Bugzilla-Changed-Fields: Message-ID: In-Reply-To: References: Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable X-Bugzilla-URL: http://gcc.gnu.org/bugzilla/ Auto-Submitted: auto-generated MIME-Version: 1.0 X-SW-Source: 2018-06/txt/msg00478.txt.bz2 Content-length: 217 https://gcc.gnu.org/bugzilla/show_bug.cgi?id=86079 --- Comment #2 from Andreas Schwab --- I don't see any difference in the preprocessor out with or without -P apart from the line comments. >From gcc-bugs-return-606684-listarch-gcc-bugs=gcc.gnu.org@gcc.gnu.org Thu Jun 07 09:05:34 2018 Return-Path: Delivered-To: listarch-gcc-bugs@gcc.gnu.org Received: (qmail 26063 invoked by alias); 7 Jun 2018 09:05:34 -0000 Mailing-List: contact gcc-bugs-help@gcc.gnu.org; run by ezmlm Precedence: bulk List-Id: List-Archive: List-Post: List-Help: Sender: gcc-bugs-owner@gcc.gnu.org Delivered-To: mailing list gcc-bugs@gcc.gnu.org Received: (qmail 25965 invoked by uid 48); 7 Jun 2018 09:05:28 -0000 From: "schwab@linux-m68k.org" To: gcc-bugs@gcc.gnu.org Subject: [Bug preprocessor/86079] preprocessor fails to splice lines Date: Thu, 07 Jun 2018 09:05:00 -0000 X-Bugzilla-Reason: CC X-Bugzilla-Type: changed X-Bugzilla-Watch-Reason: None X-Bugzilla-Product: gcc X-Bugzilla-Component: preprocessor X-Bugzilla-Version: 8.1.0 X-Bugzilla-Keywords: X-Bugzilla-Severity: normal X-Bugzilla-Who: schwab@linux-m68k.org X-Bugzilla-Status: UNCONFIRMED X-Bugzilla-Resolution: X-Bugzilla-Priority: P3 X-Bugzilla-Assigned-To: unassigned at gcc dot gnu.org X-Bugzilla-Target-Milestone: --- X-Bugzilla-Flags: X-Bugzilla-Changed-Fields: Message-ID: In-Reply-To: References: Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable X-Bugzilla-URL: http://gcc.gnu.org/bugzilla/ Auto-Submitted: auto-generated MIME-Version: 1.0 X-SW-Source: 2018-06/txt/msg00479.txt.bz2 Content-length: 179 https://gcc.gnu.org/bugzilla/show_bug.cgi?id=86079 --- Comment #3 from Andreas Schwab --- Did you use -xassembler-with-cpp?

In which case should this still retain the P1 status ? The builds are ok since Alex's patch and we need to look at this at some point of time. Richard E and I have been talking about whether ccfsm actually makes sense in 2018 and whether we should just rip it out anyway and make sure that the rtl optimizers get it right rather than carry this in the far future. It's only used in A32 state, it's probably not got a huge amount going for it and maybe we should just rip it out. >From gcc-bugs-return-606717-listarch-gcc-bugs=gcc.gnu.org@gcc.gnu.org Thu Jun 07 14:01:25 2018 Return-Path: Delivered-To: listarch-gcc-bugs@gcc.gnu.org Received: (qmail 83368 invoked by alias); 7 Jun 2018 14:01:24 -0000 Mailing-List: contact gcc-bugs-help@gcc.gnu.org; run by ezmlm Precedence: bulk List-Id: List-Archive: List-Post: List-Help: Sender: gcc-bugs-owner@gcc.gnu.org Delivered-To: mailing list gcc-bugs@gcc.gnu.org Received: (qmail 82957 invoked by uid 55); 7 Jun 2018 14:01:09 -0000 From: "bergner at gcc dot gnu.org" To: gcc-bugs@gcc.gnu.org Subject: [Bug target/63177] Powerpc no-vfa-vect-depend-2.c and no-vfa-vect-depend-3.c failures Date: Thu, 07 Jun 2018 14:01:00 -0000 X-Bugzilla-Reason: CC X-Bugzilla-Type: changed X-Bugzilla-Watch-Reason: None X-Bugzilla-Product: gcc X-Bugzilla-Component: target X-Bugzilla-Version: 4.9.0 X-Bugzilla-Keywords: X-Bugzilla-Severity: normal X-Bugzilla-Who: bergner at gcc dot gnu.org X-Bugzilla-Status: ASSIGNED X-Bugzilla-Resolution: X-Bugzilla-Priority: P3 X-Bugzilla-Assigned-To: bergner at gcc dot gnu.org X-Bugzilla-Target-Milestone: --- X-Bugzilla-Flags: X-Bugzilla-Changed-Fields: Message-ID: In-Reply-To: References: Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable X-Bugzilla-URL: http://gcc.gnu.org/bugzilla/ Auto-Submitted: auto-generated MIME-Version: 1.0 X-SW-Source: 2018-06/txt/msg00512.txt.bz2 Content-length: 627 https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63177 --- Comment #12 from Peter Bergner --- Author: bergner Date: Thu Jun 7 13:59:37 2018 New Revision: 261275 URL: https://gcc.gnu.org/viewcvs?rev=261275&root=gcc&view=rev Log: Backport from mainline 2018-06-06 Peter Bergner PR target/63177 * /config/rs6000/rs6000.h (ASM_CPU_SPEC): Add support for -mpower9.

I couldn't figure it out > (how to construct A). The point of the test is that GCC calls the vector(initializer_list) constructor (which I deleted so that we get an error if it's used, i.e. it wasn't meant to be a runtime test, just compile-time). I thought that v{std::move(v)} should have called the vector move constructor, but actually https://wg21.link/cwg2137 says that GCC is right here (and Clang and EDG don't implement that DR yet, in Clang's case because it was found to create other problems). But GCC seems to be doing the right thing here. >From gcc-bugs-return-606725-listarch-gcc-bugs=gcc.gnu.org@gcc.gnu.org Thu Jun 07 15:14:00 2018 Return-Path: Delivered-To: listarch-gcc-bugs@gcc.gnu.org Received: (qmail 70991 invoked by alias); 7 Jun 2018 15:14:00 -0000 Mailing-List: contact gcc-bugs-help@gcc.gnu.org; run by ezmlm Precedence: bulk List-Id: List-Archive: List-Post: List-Help: Sender: gcc-bugs-owner@gcc.gnu.org Delivered-To: mailing list gcc-bugs@gcc.gnu.org Received: (qmail 70900 invoked by uid 48); 7 Jun 2018 15:13:56 -0000 From: "krebbel at gcc dot gnu.org" To: gcc-bugs@gcc.gnu.org Subject: [Bug c++/86082] New: user-defined literals are not converted to the execution charset Date: Thu, 07 Jun 2018 15:14:00 -0000 X-Bugzilla-Reason: CC X-Bugzilla-Type: new X-Bugzilla-Watch-Reason: None X-Bugzilla-Product: gcc X-Bugzilla-Component: c++ X-Bugzilla-Version: 8.0.1 X-Bugzilla-Keywords: X-Bugzilla-Severity: normal X-Bugzilla-Who: krebbel at gcc dot gnu.org X-Bugzilla-Status: UNCONFIRMED X-Bugzilla-Resolution: X-Bugzilla-Priority: P3 X-Bugzilla-Assigned-To: unassigned at gcc dot gnu.org X-Bugzilla-Target-Milestone: --- X-Bugzilla-Flags: X-Bugzilla-Changed-Fields: bug_id short_desc product version bug_status bug_severity priority component assigned_to reporter target_milestone Message-ID: Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable X-Bugzilla-URL: http://gcc.gnu.org/bugzilla/ Auto-Submitted: auto-generated MIME-Version: 1.0 X-SW-Source: 2018-06/txt/msg00520.txt.bz2 Content-length: 1445 https://gcc.gnu.org/bugzilla/show_bug.cgi?id=86082 Bug ID: 86082 Summary: user-defined literals are not converted to the execution charset Product: gcc Version: 8.0.1 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: krebbel at gcc dot gnu.org Target Milestone: --- template void q(); template <> void q<'1','2','3'>() {} template void operator""_test() { q (); } int main () { 123_test; } builds fine with 'g++ t.cpp' but triggers a link error compiled with 'g++ t.cpp -fexec-charset=IBM1047' In the specialization of q the string literals '1', '2', '3' get converted to the target character set as expected.

It's a trivial enhancement to have the pass consider value ranges and implement the tracking in the non-constant case so that the bodies of both functions below are eliminated and not just that of f(). $ cat c.c && gcc -O2 -S -Wall -Wextra -fdump-tree-optimized=/dev/stdout c.c void f (void) { char a[] = "123"; a[1] = '4'; if (__builtin_strlen (a) != 3) // folded __builtin_abort (); } void g (unsigned i) { char a[] = "123"; a[1] = '0' + (i % 10); if (__builtin_strlen (a) != 3) // not folded __builtin_abort (); } ;; Function f (f, funcdef_no=0, decl_uid=1956, cgraph_uid=0, symbol_order=0) f () { [local count: 1073741825]: return; } ;; Function g (g, funcdef_no=1, decl_uid=1960, cgraph_uid=1, symbol_order=1) g (unsigned int i) { char a[4]; unsigned int _1; unsigned char _2; unsigned char _3; char _4; long unsigned int _5; [local count: 1073741825]: a = "123"; _1 = i_8(D) % 10; _2 = (unsigned char) _1; _3 = _2 + 48; _4 = (char) _3; a[1] = _4; _5 = __builtin_strlen (&a); if (_5 != 3) goto ; [0.00%] else goto ; [99.96%] [count: 0]: __builtin_abort (); [local count: 1073312327]: a ={v} {CLOBBER}; return; } >From gcc-bugs-return-606732-listarch-gcc-bugs=gcc.gnu.org@gcc.gnu.org Thu Jun 07 17:34:21 2018 Return-Path: Delivered-To: listarch-gcc-bugs@gcc.gnu.org Received: (qmail 127099 invoked by alias); 7 Jun 2018 17:34:20 -0000 Mailing-List: contact gcc-bugs-help@gcc.gnu.org; run by ezmlm Precedence: bulk List-Id: List-Archive: List-Post: List-Help: Sender: gcc-bugs-owner@gcc.gnu.org Delivered-To: mailing list gcc-bugs@gcc.gnu.org Received: (qmail 126923 invoked by uid 55); 7 Jun 2018 17:34:16 -0000 From: "tkoenig at gcc dot gnu.org" To: gcc-bugs@gcc.gnu.org Subject: [Bug fortran/85641] [7/8/9 Regression] ICE with string concatenate Date: Thu, 07 Jun 2018 17:34:00 -0000 X-Bugzilla-Reason: CC X-Bugzilla-Type: changed X-Bugzilla-Watch-Reason: None X-Bugzilla-Product: gcc X-Bugzilla-Component: fortran X-Bugzilla-Version: 7.3.1 X-Bugzilla-Keywords: ice-on-valid-code X-Bugzilla-Severity: normal X-Bugzilla-Who: tkoenig at gcc dot gnu.org X-Bugzilla-Status: ASSIGNED X-Bugzilla-Resolution: X-Bugzilla-Priority: P4 X-Bugzilla-Assigned-To: tkoenig at gcc dot gnu.org X-Bugzilla-Target-Milestone: 7.4 X-Bugzilla-Flags: X-Bugzilla-Changed-Fields: Message-ID: In-Reply-To: References: Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable X-Bugzilla-URL: http://gcc.gnu.org/bugzilla/ Auto-Submitted: auto-generated MIME-Version: 1.0 X-SW-Source: 2018-06/txt/msg00527.txt.bz2 Content-length: 927 https://gcc.gnu.org/bugzilla/show_bug.cgi?id=85641 --- Comment #6 from Thomas Koenig --- Author: tkoenig Date: Thu Jun 7 17:33:44 2018 New Revision: 261285 URL: https://gcc.gnu.org/viewcvs?rev=261285&root=gcc&view=rev Log: 2018-06-07 Thomas Koenig PR fortran/85641 Backport from trunk. * frontend-passes.c (is_fe_temp): Add prototype.

A Fortran compiler is free to assume that a function does not have side-effects. The Fortran standard does provide a programmer with the PURE and IMPURE attribute that can be used to provide hints to the compiler. If neither PURE nor IMPURE appears in a function declaration, the standard does not specify how the function is treated with respect to pureness of impureness. It is also noted that only requirement on IMPURE is with an IMPURE ELEMENTAL subprogram. In this situation, the array elements of an actual argument must be handled in array element order. There is, however, a bug with respect to F2018: C1588 A local variable of a pure subprogram, or of a BLOCK construct within a pure subprogram, shall not have the SAVE or VOLATILE attribute. gfortran is required to issue an error message, which she doesn't at the moment. Other than fixing C1588, I think this should be closed as WONTFIX. A programmer, who depends on function side-effects, should have his or her programming card revoked. >From gcc-bugs-return-606758-listarch-gcc-bugs=gcc.gnu.org@gcc.gnu.org Fri Jun 08 04:04:49 2018 Return-Path: Delivered-To: listarch-gcc-bugs@gcc.gnu.org Received: (qmail 32485 invoked by alias); 8 Jun 2018 04:04:49 -0000 Mailing-List: contact gcc-bugs-help@gcc.gnu.org; run by ezmlm Precedence: bulk List-Id: List-Archive: List-Post: List-Help: Sender: gcc-bugs-owner@gcc.gnu.org Delivered-To: mailing list gcc-bugs@gcc.gnu.org Received: (qmail 32449 invoked by uid 48); 8 Jun 2018 04:04:45 -0000 From: "shibatch at users dot sourceforge.net" To: gcc-bugs@gcc.gnu.org Subject: [Bug libgomp/86088] New: #pragma omp parallel for freezes if other processes are running Date: Fri, 08 Jun 2018 04:04:00 -0000 X-Bugzilla-Reason: CC X-Bugzilla-Type: new X-Bugzilla-Watch-Reason: None X-Bugzilla-Product: gcc X-Bugzilla-Component: libgomp X-Bugzilla-Version: 8.1.0 X-Bugzilla-Keywords: X-Bugzilla-Severity: normal X-Bugzilla-Who: shibatch at users dot sourceforge.net X-Bugzilla-Status: UNCONFIRMED X-Bugzilla-Resolution: X-Bugzilla-Priority: P3 X-Bugzilla-Assigned-To: unassigned at gcc dot gnu.org X-Bugzilla-Target-Milestone: --- X-Bugzilla-Flags: X-Bugzilla-Changed-Fields: bug_id short_desc product version bug_status bug_severity priority component assigned_to reporter cc target_milestone Message-ID: Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable X-Bugzilla-URL: http://gcc.gnu.org/bugzilla/ Auto-Submitted: auto-generated MIME-Version: 1.0 X-SW-Source: 2018-06/txt/msg00553.txt.bz2 Content-length: 1252 https://gcc.gnu.org/bugzilla/show_bug.cgi?id=86088 Bug ID: 86088 Summary: #pragma omp parallel for freezes if other processes are running Product: gcc Version: 8.1.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: libgomp Assignee: unassigned at gcc dot gnu.org Reporter: shibatch at users dot sourceforge.net CC: jakub at gcc dot gnu.org Target Milestone: --- The following small program takes more than 20 seconds to finish.

So it is all about the OMP_WAIT_POLICY or GOMP_SPINCOUNT in this case, for oversubscribed case you want to lower the spincount and at the expense of bigger latencies. So just use OMP_WAIT_POLICY=passive or GOMP_SPINCOUNT=some_low_number. >From gcc-bugs-return-606762-listarch-gcc-bugs=gcc.gnu.org@gcc.gnu.org Fri Jun 08 08:16:29 2018 Return-Path: Delivered-To: listarch-gcc-bugs@gcc.gnu.org Received: (qmail 101561 invoked by alias); 8 Jun 2018 08:16:28 -0000 Mailing-List: contact gcc-bugs-help@gcc.gnu.org; run by ezmlm Precedence: bulk List-Id: List-Archive: List-Post: List-Help: Sender: gcc-bugs-owner@gcc.gnu.org Delivered-To: mailing list gcc-bugs@gcc.gnu.org Received: (qmail 100928 invoked by uid 48); 8 Jun 2018 08:16:23 -0000 From: "fxcoudert at gcc dot gnu.org" To: gcc-bugs@gcc.gnu.org Subject: [Bug target/82092] [8/9 regression] gcc fails to link genmodes on darwin (cfiStartsArray[i] != cfiStartsArray[i-1]) Date: Fri, 08 Jun 2018 08:16:00 -0000 X-Bugzilla-Reason: CC X-Bugzilla-Type: changed X-Bugzilla-Watch-Reason: None X-Bugzilla-Product: gcc X-Bugzilla-Component: target X-Bugzilla-Version: 8.0 X-Bugzilla-Keywords: build X-Bugzilla-Severity: normal X-Bugzilla-Who: fxcoudert at gcc dot gnu.org X-Bugzilla-Status: NEW X-Bugzilla-Resolution: X-Bugzilla-Priority: P3 X-Bugzilla-Assigned-To: unassigned at gcc dot gnu.org X-Bugzilla-Target-Milestone: --- X-Bugzilla-Flags: X-Bugzilla-Changed-Fields: cc Message-ID: In-Reply-To: References: Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable X-Bugzilla-URL: http://gcc.gnu.org/bugzilla/ Auto-Submitted: auto-generated MIME-Version: 1.0 X-SW-Source: 2018-06/txt/msg00557.txt.bz2 Content-length: 620 https://gcc.gnu.org/bugzilla/show_bug.cgi?id=82092 Francois-Xavier Coudert changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |fxcoudert at gcc dot gnu.org --- Comment #14 from Francois-Xavier Coudert --- Homebrew has been shipping GCC 8.1.0 (unmatched) since release: it builds fine on our CI machines, and we haven't had a user bug report since then.

I notice that store-merging does not merge these stores, I didn't check why. SLP can do it for long but not for int (no vector of 2 ints) with -fdisable-tree-vect. (anyway that's too late for ldist, the DR / vectorizer approach sounds better, just mentioning this as another possible missed optimization) The testcase is a simplified version of boost::container::flat_map. The most important missing transformation is memmove, but it was easier to report memcpy and I kind of expect that they may all be fixed together. >From gcc-bugs-return-606776-listarch-gcc-bugs=gcc.gnu.org@gcc.gnu.org Fri Jun 08 13:36:48 2018 Return-Path: Delivered-To: listarch-gcc-bugs@gcc.gnu.org Received: (qmail 64152 invoked by alias); 8 Jun 2018 13:36:48 -0000 Mailing-List: contact gcc-bugs-help@gcc.gnu.org; run by ezmlm Precedence: bulk List-Id: List-Archive: List-Post: List-Help: Sender: gcc-bugs-owner@gcc.gnu.org Delivered-To: mailing list gcc-bugs@gcc.gnu.org Received: (qmail 64016 invoked by uid 48); 8 Jun 2018 13:36:43 -0000 From: "amker at gcc dot gnu.org" To: gcc-bugs@gcc.gnu.org Subject: [Bug tree-optimization/86024] Missed memcpy loop distribution with elementwise copy Date: Fri, 08 Jun 2018 13:36:00 -0000 X-Bugzilla-Reason: CC X-Bugzilla-Type: changed X-Bugzilla-Watch-Reason: None X-Bugzilla-Product: gcc X-Bugzilla-Component: tree-optimization X-Bugzilla-Version: 9.0 X-Bugzilla-Keywords: missed-optimization X-Bugzilla-Severity: normal X-Bugzilla-Who: amker at gcc dot gnu.org X-Bugzilla-Status: NEW X-Bugzilla-Resolution: X-Bugzilla-Priority: P3 X-Bugzilla-Assigned-To: unassigned at gcc dot gnu.org X-Bugzilla-Target-Milestone: --- X-Bugzilla-Flags: X-Bugzilla-Changed-Fields: Message-ID: In-Reply-To: References: Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable X-Bugzilla-URL: http://gcc.gnu.org/bugzilla/ Auto-Submitted: auto-generated MIME-Version: 1.0 X-SW-Source: 2018-06/txt/msg00571.txt.bz2 Content-length: 820 https://gcc.gnu.org/bugzilla/show_bug.cgi?id=86024 --- Comment #3 from bin cheng --- (In reply to Marc Glisse from comment #2) > (In reply to Richard Biener from comment #1) > > Or we may want to un-"SRA" such patterns, generating aggregate copies. > > I notice that store-merging does not merge these stores, I didn't check why. > SLP can do it for long but not for int (no vector of 2 ints) with > -fdisable-tree-vect. > > (anyway that's too late for ldist, the DR / vectorizer approach sounds > better, just mentioning this as another possible missed optimization) Yes, merging and SRA are conflicting with each other here, and it's difficult to get a model deciding when to do what.

What I have shown here is just an example sample code. But I have code which makes use of kern_buff_p variable in many place.If I use volatile that might reduce my code speed.

But now I do. Some more information has turned up in a new MacPorts ticket: https://trac.macports.org/ticket/56521 In MacPorts gcc ports, we use --with-as=/opt/local/bin/as (this assembler is provided by our cctools port). This change was made in MacPorts 6 years ago by Jeremy who reported this bug, though I'm not entirely sure why. I suspect the problem is that our cctools port is currently at version 895, which corresponds to what's in Xcode 8.1, and that's apparently too old to work properly in this case. I am able to get a more recent snapshot to build if I instead use --with-as=/usr/bin/as, so perhaps we either need to do that in MacPorts or we need to update our cctools port to a more recent version. >From gcc-bugs-return-606804-listarch-gcc-bugs=gcc.gnu.org@gcc.gnu.org Fri Jun 08 20:58:38 2018 Return-Path: Delivered-To: listarch-gcc-bugs@gcc.gnu.org Received: (qmail 24618 invoked by alias); 8 Jun 2018 20:58:37 -0000 Mailing-List: contact gcc-bugs-help@gcc.gnu.org; run by ezmlm Precedence: bulk List-Id: List-Archive: List-Post: List-Help: Sender: gcc-bugs-owner@gcc.gnu.org Delivered-To: mailing list gcc-bugs@gcc.gnu.org Received: (qmail 24576 invoked by uid 48); 8 Jun 2018 20:58:33 -0000 From: "sshannin at gmail dot com" To: gcc-bugs@gcc.gnu.org Subject: [Bug other/86095] New: stale documentation for -Wunsafe-loop-optimizations Date: Fri, 08 Jun 2018 20:58:00 -0000 X-Bugzilla-Reason: CC X-Bugzilla-Type: new X-Bugzilla-Watch-Reason: None X-Bugzilla-Product: gcc X-Bugzilla-Component: other X-Bugzilla-Version: 8.1.0 X-Bugzilla-Keywords: X-Bugzilla-Severity: normal X-Bugzilla-Who: sshannin at gmail dot com X-Bugzilla-Status: UNCONFIRMED X-Bugzilla-Resolution: X-Bugzilla-Priority: P3 X-Bugzilla-Assigned-To: unassigned at gcc dot gnu.org X-Bugzilla-Target-Milestone: --- X-Bugzilla-Flags: X-Bugzilla-Changed-Fields: bug_id short_desc product version bug_status bug_severity priority component assigned_to reporter target_milestone Message-ID: Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable X-Bugzilla-URL: http://gcc.gnu.org/bugzilla/ Auto-Submitted: auto-generated MIME-Version: 1.0 X-SW-Source: 2018-06/txt/msg00599.txt.bz2 Content-length: 977 https://gcc.gnu.org/bugzilla/show_bug.cgi?id=86095 Bug ID: 86095 Summary: stale documentation for -Wunsafe-loop-optimizations Product: gcc Version: 8.1.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: other Assignee: unassigned at gcc dot gnu.org Reporter: sshannin at gmail dot com Target Milestone: --- For the man page shipped with 8.1.0, the description of -Wunsafe-loop-optimizations still references the -funsafe-loop-optimizations option, however that optimization is neither described nor referenced anywhere else in the documentation.

Note mw_reg in the 'if' vs mw_order in the 'return'. This is invalid. It's simpler and more efficient to just use mw_order as the last tie-breaker regardless of mw_reg value. >From gcc-bugs-return-606815-listarch-gcc-bugs=gcc.gnu.org@gcc.gnu.org Sat Jun 09 13:01:04 2018 Return-Path: Delivered-To: listarch-gcc-bugs@gcc.gnu.org Received: (qmail 98917 invoked by alias);
