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/i386/20020523.c | 41 ++++++++++++++++++++++++++++++++ 1 file changed, 41 insertions(+) create mode 100644 gcc/testsuite/gcc.target/i386/20020523.c (limited to 'gcc/testsuite/gcc.target/i386/20020523.c') diff --git a/gcc/testsuite/gcc.target/i386/20020523.c b/gcc/testsuite/gcc.target/i386/20020523.c new file mode 100644 index 000000000..0684d5feb --- /dev/null +++ b/gcc/testsuite/gcc.target/i386/20020523.c @@ -0,0 +1,41 @@ +/* PR target/6753 + This testcase was miscompiled because sse_mov?fcc_const0* + patterns were missing earlyclobber. */ + +/* { dg-do run } */ +/* { dg-options "-O2 -msse -mfpmath=sse -ffast-math" } */ +/* { dg-require-effective-target sse } */ + +#include "sse-check.h" + +float one = 1.f; + +void bar (float f) +{ + if (__builtin_memcmp (&one, &f, sizeof (float))) + abort (); +} + +float foo (void) +{ + return 1.f; +} + +typedef struct +{ + float t; +} T; + +static void +sse_test (void) +{ + int i; + T x[1]; + + for (i = 0; i < 1; i++) + { + x[i].t = foo (); + x[i].t = 0.f > x[i].t ? 0.f : x[i].t; + bar (x[i].t); + } +} -- cgit v1.2.3
