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.dg/torture/pr48542.c | 57 ++++++++++++++++++++++++++++++++++ 1 file changed, 57 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/torture/pr48542.c (limited to 'gcc/testsuite/gcc.dg/torture/pr48542.c') diff --git a/gcc/testsuite/gcc.dg/torture/pr48542.c b/gcc/testsuite/gcc.dg/torture/pr48542.c new file mode 100644 index 000000000..e3e49489f --- /dev/null +++ b/gcc/testsuite/gcc.dg/torture/pr48542.c @@ -0,0 +1,57 @@ +/* { dg-do run } */ +/* The return-address was clobbered. */ +#include +#include + +jmp_buf env; +extern void sub(void); +extern void sub3(void); +int called; +__attribute__ ((__noinline__)) +int sjtest() +{ + int i; + if (setjmp(env)) + return 99; + + for (i = 0; i < 10; i++) + sub(); + + longjmp(env, 1); +} + +__attribute__ ((__noinline__)) +void sub(void) +{ + called++; +} + +int called3; +__attribute__ ((__noinline__)) +int sjtest3() +{ + int i; + if (setjmp(env)) + return 42; + + for (i = 0; i < 10; i++) + sub3(); + return 0; +} + +__attribute__ ((__noinline__)) +void sub3(void) +{ + called3++; + if (called3 == 10) + longjmp (env, 1); +} + +int main(void) +{ + if (sjtest() != 99 || called != 10) + abort(); + if (sjtest3() != 42 || called3 != 10) + abort(); + exit (0); +} -- cgit v1.2.3
