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. --- .../execute/builtins/strstr-asm-lib.c | 37 ++++++++++++++++++++++ 1 file changed, 37 insertions(+) create mode 100644 gcc/testsuite/gcc.c-torture/execute/builtins/strstr-asm-lib.c (limited to 'gcc/testsuite/gcc.c-torture/execute/builtins/strstr-asm-lib.c') diff --git a/gcc/testsuite/gcc.c-torture/execute/builtins/strstr-asm-lib.c b/gcc/testsuite/gcc.c-torture/execute/builtins/strstr-asm-lib.c new file mode 100644 index 000000000..a031a56a9 --- /dev/null +++ b/gcc/testsuite/gcc.c-torture/execute/builtins/strstr-asm-lib.c @@ -0,0 +1,37 @@ +extern void abort (void); +typedef __SIZE_TYPE__ size_t; +extern size_t strlen(const char *); +extern char *strchr(const char *, int); +extern int strcmp(const char *, const char *); +extern int strncmp(const char *, const char *, size_t); +extern int inside_main; +extern const char *p; + +char * +my_strstr (const char *s1, const char *s2) +{ + const size_t len = strlen (s2); + +#ifdef __OPTIMIZE__ + /* If optimizing, we should be called only in the strstr (foo + 2, p) + case.
