             Bug #: 54404
           Summary: [4.8 Regression] *cfstring* failures for (obj-c|g)++
                    on *-apple-darwin* after revision 186789
    Classification: Unclassified
           Product: gcc
           Version: 4.8.0
            Status: UNCONFIRMED

This is a follow up of pr53283 for the remaining failures of some *cfstring*

> This is a follow up of pr53283 for the remaining failures of some *cfstring*

This was an over simplification of the problem. On x86_64-apple-darwin10
revision 186789 introduced an ICE

g++.dg/other/darwin-cfstring1.C:13:80: internal compiler error: in
ix86_expand_builtin, at config/i386/i386.c:30398

fixed between revisions 189336 and 189490 (likely 189391). The errors reported
in comment #0 appeared only after the ICE has been fixed.

On powerpc-apple-darwin9 the failures appeared between revisions 186440 (OK)
and 187171 (failures).

For the test g++.dg/other/darwin-cfstring1.C, the error changed between
revisions 186788 and 189490 from

/opt/gcc/work/gcc/testsuite/g++.dg/other/darwin-cfstring1.C: In function 'int

The following patch adjusts the errors/notes to the present pattern while
hopefully retaining the intent of the original test

The situation for the test obj-c++.dg/strings/const-cfstring-2.mm is more
puzzling. The failures appeared in the same revision frame and is due to the
fact that the lines

  CFStringRef s4 = CFSTR("\222 - Non-ASCII literal"); /* { dg-warning
"non-ASCII character in CFString literal" } */
  CFStringRef s5 = CFSTR("Non-ASCII (\222) literal"); /* { dg-warning

  CFStringRef s8 = CFSTR("Embedded NUL\0"); /* { dg-warning "embedded NUL in

do not give the expected warnings, while the lines

  NSString *s3 = @"Non-ASCII literal - \222";         /* { dg-warning
"non-ASCII character in CFString literal" } */
 NSString *s6 = @"\0Embedded NUL";         /* { dg-warning "embedded NUL in

do: the NSString lines work as expected, but the CFStringRef one don't.

After having applied the patch for r189391, a bissection gives the range 186973
(old behavior) 186980 (new one). I think the change occurs after 186977 and the
patch is obvious (see objc.dg/foreach-7.m at r186976):

(In reply to comment #3)

Also confirmed on x86_64-apple-darwin12 that this eliminates the failures in
obj-c++.dg/strings/const-cfstring-2.mm.  On darwin12 at least, this still
leaves the failures in...

obj-c++.dg/torture/strings/const-str-10.mm
obj-c++.dg/torture/strings/const-str-11.mm
obj-c++.dg/torture/strings/const-str-9.mm 
obj-c++.dg/torture/strings/string1.mm

to be addressed as well as those in objc...

objc.dg/strings/const-cfstring-5.m
objc.dg/strings/const-str-12b.m

I don't see these errors on darwin10. Could you look at the errors in the log
files and try to sort them by categories.

Only the errors...

FAIL: obj-c++.dg/torture/strings/string1.mm  -O2 -flto -flto-partition=none 
-fnext-runtime (test for excess errors)
FAIL: obj-c++.dg/torture/strings/string1.mm  -O2 -flto  -fnext-runtime (test
for excess errors)

are seen on darwin11 with Xcode 4.5.1 (which potentially could be a linker bug
so I'll open a radar).
The remaining failures are darwin12 only and might represent ABI changes in
10.8 perhaps.

Note the the string1.m/string1.mm failures are from warnings and the resulting
binaries run fine.

These linker warnings are http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48094. I
also see these failures under darwin10 with Xcode 4.2's linker. This linker
warning doesn't occur with the linker from Xcode 3.2.6 under darwin10.

The darwin12 specific non-linker failures are suppressed if...

-isysroot `xcode-select
--print-path`/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.7.sdk

is added to the compilation flags indicating that this is an ABI change.

Note that on Mountain Lion using the 10.7 SDK solves the failures...

It would probably be nice to open a new PR for the post-darwin10 failures and
to close this one as fixed.

Actually we need one for post-darwin11 failures and another for those unique to
post-darwin12.

The question is what remaining failures are actually regressions and which SVN
revision introduced them if they are regressions.

Jack,

I don't have access to darwin11 or 12. Could you open the PR(s) you think
necessary, then I'll close this one as fixed.

The remaining issues for obj(c|-c++) are now tracked by PR 55654 and 55656.
Closing this one as fixed.
