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/builtin-return-1.c | 34 +++++++++++++++++++++++++++++++++ 1 file changed, 34 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/builtin-return-1.c (limited to 'gcc/testsuite/gcc.dg/builtin-return-1.c') diff --git a/gcc/testsuite/gcc.dg/builtin-return-1.c b/gcc/testsuite/gcc.dg/builtin-return-1.c new file mode 100644 index 000000000..68fd0556b --- /dev/null +++ b/gcc/testsuite/gcc.dg/builtin-return-1.c @@ -0,0 +1,34 @@ +/* PR middle-end/11151 */ +/* Originator: Andrew Church */ +/* { dg-do run } */ +/* { dg-xfail-run-if "PR36571 untyped return is char register" { "avr-*-*" } { "*" } { "" } } */ +/* This used to fail on SPARC because the (undefined) return + value of 'bar' was overwriting that of 'foo'. */ + +extern void abort(void); + +int foo(int n) +{ + return n+1; +} + +int bar(int n) +{ + __builtin_return(__builtin_apply((void (*)(void))foo, __builtin_apply_args(), 64)); +} + +char *g; + +int main(void) +{ + /* Allocate 64 bytes on the stack to make sure that __builtin_apply + can read at least 64 bytes above the return address. */ + char dummy[64]; + + g = dummy; + + if (bar(1) != 2) + abort(); + + return 0; +} -- cgit v1.2.3
