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.c-torture/execute/builtins/lib/memcmp.c | 23 ++++++++++++++++++++++ 1 file changed, 23 insertions(+) create mode 100644 gcc/testsuite/gcc.c-torture/execute/builtins/lib/memcmp.c (limited to 'gcc/testsuite/gcc.c-torture/execute/builtins/lib/memcmp.c') diff --git a/gcc/testsuite/gcc.c-torture/execute/builtins/lib/memcmp.c b/gcc/testsuite/gcc.c-torture/execute/builtins/lib/memcmp.c new file mode 100644 index 000000000..fd6556d22 --- /dev/null +++ b/gcc/testsuite/gcc.c-torture/execute/builtins/lib/memcmp.c @@ -0,0 +1,23 @@ +extern void abort(void); +extern int inside_main; + +__attribute__ ((__noinline__)) +int +memcmp (const void *s1, const void *s2, __SIZE_TYPE__ len) +{ + const unsigned char *sp1, *sp2; + +#ifdef __OPTIMIZE__ + if (inside_main) + abort (); +#endif + + sp1 = s1; + sp2 = s2; + while (len != 0 && *sp1 == *sp2) + sp1++, sp2++, len--; + + if (len == 0) + return 0; + return *sp1 - *sp2; +} -- cgit v1.2.3
