[Bug driver/63810] New: gcc sets incorrect macro for OS X deployment targets

            Bug ID: 63810
           Summary: gcc sets incorrect macro for OS X deployment targets
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: driver
          Assignee: unassigned at gcc dot gnu.org
          Reporter: jeremyhu at macports dot org

Even after the change for bug #61407, gcc is not setting up the deployment
target macro correctly.  gcc always sets the tiny version to 0 which is not
always the case.  For example:

$ echo | clang-mp-3.5 -E -dM - -mmacosx-version-min=10.09.04 | grep
__ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__
#define __ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__ 1094

patch against trunk for handling deployment targets correctly

This is more of a rewrite than just a patch. I've divorced parsing of the
version string from assembly of legacy macro values from assembly of modern
macro values. It should hopefully be easier to make adjustments in the future,
since this code is more than a crude DFA implementation.

patch against 4.9 branch for handling deployment targets correctly

Patched GCC 4.9.2 matched the behavior of Apple LLVM Compiler 6.0
(clang-600.0.54) over 8,451 out of 8,464 test strings. The 13 mismatches are
due to a bug in clang.

            Bug ID: 63862
           Summary: C frontend converts shift-count to int while standard
                    wants integer promotions
           Product: gcc
           Version: 5.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: rguenth at gcc dot gnu.org
                CC: jsm28 at gcc dot gnu.org

/* Convert the non vector shift-count to an integer, regardless
             of size of value being shifted.  */
          if (TREE_CODE (TREE_TYPE (op1)) != VECTOR_TYPE
              && TYPE_MAIN_VARIANT (TREE_TYPE (op1)) != integer_type_node)
            op1 = convert (integer_type_node, op1);

while C99 6.5.7 says "The integer promotions are performed on each of the
operands".

The above pessimizes gcc.c-torture/execute/shiftopt-1.c which does

void
utest (unsigned int x)
{
  if (-1 >> x != -1)
    link_error ();
}

and thus expects us to know that the shift amount is nonnegative.  But
with the C frontend generating -1 >> (int)x we don't know that anymore
(and thus if I fix the bogus fold-const.c code which strips sign-changing
conversions on x before asking tree_expr_nonnegative_p it fails to optimize).

It is semantically incorrect and not syntactically incorrect.  Basically
-fsyntax-only includes most of the semantics analysis, why not this one too.

fails on the trunk or only with my code changes.

            Bug ID: 63926
           Summary: [5 Regression] ICE in estimate_edge_growth, at
                    ipa-inline.h:300
           Product: gcc
           Version: 5.0

Hey Lawrence, do you have a copyright assignment in place with the FSF? If so,
please submit your trunk patch to gcc-patches@gcc.gnu.org for review. If not,
ask on the gcc@gcc.gnu.org list for the paperwork to be sent to you.

Yeah, 4.6 20100620 rejects that (no support for vector array subscripts), 4.8
ICEs, don't have anything in between.
That said, if something regressed because of  r217125, it better should be
analyzed what changed, because hopefully that change should affect only
-fcheck-pointer-bounds.  If not, something went very wrong.

Can you add a main() with the necessary parameter setup and call to mark_set()
to make the testcase self-contained and executable?  You can annotate
mark_set() with attribute((noinline,noclone)) to prevent it from being inlined
into main() or specialized wrt to the specific parameters there.

Sorry, it took me a while to obtain the paperwork, and even longer to get
around to submitting it.

Quick review of the patch:

 - version_as_modern_macro(): you implement a specific behavior for major <= 9,
but it's necessary at all. Having major <= 9 is simply impossible (and Apple's
compiler rejects it). I'd say let's make things simpler anduse a format of
"%02lu%02lu%02lu" and always be 6 characters long.

 - version_as_legacy_macro(): same issue. Why do we need to handle major <= 9?
You have rejected this possibility in macosx_version_as_macro() anyway.
Simplify here also.

 - throughout the patch, writing things like "(int) sizeof "9999" - 1" or "char
result[sizeof "9999"]" when you could write "4" and "char result[4]" means
harder code to read, and no real benefit in terms of security or
maintainability (since you're duplicating stuff anyway).

 - in macosx_version_as_macro(), you say "Allow for future major numbers
greater than 10", but you actually reject them (and that's OK). Adjust the
comment.

 - later, "version_array[MAJOR] == 10" is guaranteed. Remove it.

 - in parse_version(), the string passed is guaranteed to be non-NULL. No need
to test it.

I don't see anything in version_as_legacy_macro() that specifically deals with
major <= 9. Could you point me to the offending code?

In the comment above it ("Major numbers are zero-padded if necessary"), and the
sprintf format "%02lu%lu%lu" (which can be "%lu%lu%lu").

            Bug ID: 66230
           Summary: Using optimizations causes program to segfault
           Product: gcc
           Version: 4.9.2
            Status: UNCONFIRMED
          Severity: major
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: gpnuma at centaurean dot com
  Target Milestone: ---

Hello,

First I'd like to point out that the code producing this error compiles and
runs fine in gcc 4.8.4-1 for Linux and OS/X and Clang 3.5, 3.6 (Linux) and 6.1
(OS/X), but fails with gcc 4.9.2 when using -O3 on both Linux and OS/X (in
debug mode it works fine).
The platform used for all these tests was x86_64.

To reproduce : clone and build https://github.com/centaurean/density with gcc
4.9.2.
Then run the following command :
./benchmark -3 some_file

This will turn into a segfault.

When I add the line [printf("anything");] just before DENSITY_MEMCPY(... here :
https://github.com/centaurean/density/blob/master/src/kernel_lion_decode.c#L187,
the program runs again normally without any segfault... that's really super
strange.

The function that fails is called via an array of function pointers, but I
