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/built-in-setjmp.c | 39 ++++++++++++++++++++++ 1 file changed, 39 insertions(+) create mode 100644 gcc/testsuite/gcc.c-torture/execute/built-in-setjmp.c (limited to 'gcc/testsuite/gcc.c-torture/execute/built-in-setjmp.c') diff --git a/gcc/testsuite/gcc.c-torture/execute/built-in-setjmp.c b/gcc/testsuite/gcc.c-torture/execute/built-in-setjmp.c new file mode 100644 index 000000000..9da787884 --- /dev/null +++ b/gcc/testsuite/gcc.c-torture/execute/built-in-setjmp.c @@ -0,0 +1,39 @@ +extern int strcmp(const char *, const char *); +extern char *strcpy(char *, const char *); +extern void abort(void); +extern void exit(int); + +void *buf[20]; + +void __attribute__((noinline)) +sub2 (void) +{ + __builtin_longjmp (buf, 1); +} + +int +main () +{ + char *p = (char *) __builtin_alloca (20); + + strcpy (p, "test"); + + if (__builtin_setjmp (buf)) + { + if (strcmp (p, "test") != 0) + abort (); + + exit (0); + } + + { + int *q = (int *) __builtin_alloca (p[2] * sizeof (int)); + int i; + + for (i = 0; i < p[2]; i++) + q[i] = 0; + + while (1) + sub2 (); + } +} -- cgit v1.2.3
