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/gcc.target/i386/20020616-1.c | 35 ++++++++++++++++++++++++++++++ 1 file changed, 35 insertions(+) create mode 100644 gcc/testsuite/gcc.target/i386/20020616-1.c (limited to 'gcc/testsuite/gcc.target/i386/20020616-1.c') diff --git a/gcc/testsuite/gcc.target/i386/20020616-1.c b/gcc/testsuite/gcc.target/i386/20020616-1.c new file mode 100644 index 000000000..5641826b4 --- /dev/null +++ b/gcc/testsuite/gcc.target/i386/20020616-1.c @@ -0,0 +1,35 @@ +/* PR opt/6722 */ +/* { dg-do run } */ +/* { dg-options "-O2" } */ + +#if !__PIC__ +register int k asm("%ebx"); +#elif __amd64 +register int k asm("%r12"); +#else +register int k asm("%esi"); +#endif + +void __attribute__((noinline)) +foo() +{ + k = 1; +} + +void test() +{ + int i; + for (i = 0; i < 10; i += k) + { + k = 0; + foo(); + } +} + +int main() +{ + int old = k; + test(); + k = old; + return 0; +} -- cgit v1.2.3
