From 554fd8c5195424bdbcabf5de30fdc183aba391bd Mon Sep 17 00:00:00 2001 From: upstream source tree Date: Sun, 15 Mar 2015 20:14:05 -0400 Subject: obtained gcc-4.6.4.tar.bz2 from upstream website; verified gcc-4.6.4.tar.bz2.sig; imported gcc-4.6.4 source tree from verified upstream tarball. downloading a git-generated archive based on the 'upstream' tag should provide you with a source tree that is binary identical to the one extracted from the above tarball. if you have obtained the source via the command 'git clone', however, do note that line-endings of files in your working directory might differ from line-endings of the respective files in the upstream repository. --- gcc/testsuite/g++.dg/opt/inline9.C | 29 +++++++++++++++++++++++++++++ 1 file changed, 29 insertions(+) create mode 100644 gcc/testsuite/g++.dg/opt/inline9.C (limited to 'gcc/testsuite/g++.dg/opt/inline9.C') diff --git a/gcc/testsuite/g++.dg/opt/inline9.C b/gcc/testsuite/g++.dg/opt/inline9.C new file mode 100644 index 000000000..10bc54ccd --- /dev/null +++ b/gcc/testsuite/g++.dg/opt/inline9.C @@ -0,0 +1,29 @@ +// PR c++/17972 +// Origin: Michal Ostrowski +// Testcase by Alan Modra +// { dg-do run } +// { dg-options "-O" } +// { dg-options "-O -mtune=i686" { target { { i?86-*-* x86_64-*-* } && ilp32 } } } + +struct thread_info +{ + short preempt_count; +} x; + +static inline struct thread_info *cti (void) __attribute__ ((const)); +static inline struct thread_info *cti (void) +{ + return &x; +} + +void fn (void) __attribute__ ((noinline)); +void fn (void) +{ + ++cti()->preempt_count; +} + +int main (void) +{ + fn (); + return 0; +} -- cgit v1.2.3
