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.dg/pr31507-1.c | 41 ++++++++++++++++++++++++++++++++++++++++ 1 file changed, 41 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/pr31507-1.c (limited to 'gcc/testsuite/gcc.dg/pr31507-1.c') diff --git a/gcc/testsuite/gcc.dg/pr31507-1.c b/gcc/testsuite/gcc.dg/pr31507-1.c new file mode 100644 index 000000000..dbba1e1fc --- /dev/null +++ b/gcc/testsuite/gcc.dg/pr31507-1.c @@ -0,0 +1,41 @@ +/* PR target/31507 */ +/* { dg-do run } */ +/* { dg-options "-Os -fno-omit-frame-pointer" } */ + +extern void abort (void); + +__attribute__((noinline)) void +foo (double d0, double d1, double d2, double d3, + double d4, double d5, double d6, double d7, + float f0, float f1, float f2, float f3, + char *p) +{ + if (d0 != 0 || d1 != 1 || d2 != 2 || d3 != 3) + abort (); + if (d4 != 4 || d5 != 5 || d6 != 6 || d7 != 7) + abort (); + if (f0 != 10 || f1 != 11 || f2 != 12 || f3 != 13) + abort (); + if (__builtin_memcmp (p, "foo", 4) != 0) + abort (); + __builtin_memcpy (p, "bar", 4); +} + +__attribute__((noinline)) void +bar (int x) +{ + char p[x]; + if (x >= sizeof "foo") + __builtin_memcpy (p, "foo", 4); + foo (0.0, 1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, + 10.0f, 11.0f, 12.0f, 13.0f, p); + if (x >= sizeof "bar" && __builtin_memcmp (p, "bar", 4) != 0) + abort (); +} + +int +main (void) +{ + bar (128); + return 0; +} -- cgit v1.2.3
