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.c-torture/compile/20031023-1.c | 66 ++++++++++++++++++++++++ 1 file changed, 66 insertions(+) create mode 100644 gcc/testsuite/gcc.c-torture/compile/20031023-1.c (limited to 'gcc/testsuite/gcc.c-torture/compile/20031023-1.c') diff --git a/gcc/testsuite/gcc.c-torture/compile/20031023-1.c b/gcc/testsuite/gcc.c-torture/compile/20031023-1.c new file mode 100644 index 000000000..67f8ea918 --- /dev/null +++ b/gcc/testsuite/gcc.c-torture/compile/20031023-1.c @@ -0,0 +1,66 @@ +#ifndef ASIZE +# define ASIZE 0x10000000000UL +#endif + +#include + +#if LONG_MAX < 8 * ASIZE +# undef ASIZE +# define ASIZE 4096 +#endif + +extern void abort (void); + +int __attribute__((noinline)) +foo (const char *s) +{ + if (!s) + return 1; + if (s[0] != 'a') + abort (); + s += ASIZE - 1; + if (s[0] != 'b') + abort (); + return 0; +} + +int (*fn) (const char *) = foo; + +int __attribute__((noinline)) +bar (void) +{ + char s[ASIZE]; + s[0] = 'a'; + s[ASIZE - 1] = 'b'; + foo (s); + foo (s); + return 0; +} + +int __attribute__((noinline)) +baz (long i) +{ + if (i) + return fn (0); + else + { + char s[ASIZE]; + s[0] = 'a'; + s[ASIZE - 1] = 'b'; + foo (s); + foo (s); + return fn (0); + } +} + +int +main (void) +{ + if (bar ()) + abort (); + if (baz (0) != 1) + abort (); + if (baz (1) != 1) + abort (); + return 0; +} -- cgit v1.2.3
