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/strstr-asm.c | 45 ++++++++++++++++++++++ 1 file changed, 45 insertions(+) create mode 100644 gcc/testsuite/gcc.c-torture/execute/builtins/strstr-asm.c (limited to 'gcc/testsuite/gcc.c-torture/execute/builtins/strstr-asm.c') diff --git a/gcc/testsuite/gcc.c-torture/execute/builtins/strstr-asm.c b/gcc/testsuite/gcc.c-torture/execute/builtins/strstr-asm.c new file mode 100644 index 000000000..3c3e45dfa --- /dev/null +++ b/gcc/testsuite/gcc.c-torture/execute/builtins/strstr-asm.c @@ -0,0 +1,45 @@ +/* Copyright (C) 2000, 2003 Free Software Foundation. + + Ensure all expected transformations of builtin strstr occur and + perform correctly in presence of redirect. */ + +#define ASMNAME(cname) ASMNAME2 (__USER_LABEL_PREFIX__, cname) +#define ASMNAME2(prefix, cname) STRING (prefix) cname +#define STRING(x) #x + +typedef __SIZE_TYPE__ size_t; +extern void abort (void); +extern char *strstr (const char *, const char *) + __asm (ASMNAME ("my_strstr")); + +const char *p = "rld", *q = "hello world"; + +void +main_test (void) +{ + const char *const foo = "hello world"; + + if (strstr (foo, "") != foo) + abort (); + if (strstr (foo + 4, "") != foo + 4) + abort (); + if (strstr (foo, "h") != foo) + abort (); + if (strstr (foo, "w") != foo + 6) + abort (); + if (strstr (foo + 6, "o") != foo + 7) + abort (); + if (strstr (foo + 1, "world") != foo + 6) + abort (); + if (strstr (foo + 2, p) != foo + 8) + abort (); + if (strstr (q, "") != q) + abort (); + if (strstr (q + 1, "o") != q + 4) + abort (); + + /* Test at least one instance of the __builtin_ style.
