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/execute/pr40657.c | 23 +++++++++++++++++++++++ 1 file changed, 23 insertions(+) create mode 100644 gcc/testsuite/gcc.c-torture/execute/pr40657.c (limited to 'gcc/testsuite/gcc.c-torture/execute/pr40657.c') diff --git a/gcc/testsuite/gcc.c-torture/execute/pr40657.c b/gcc/testsuite/gcc.c-torture/execute/pr40657.c new file mode 100644 index 000000000..e6d8dda9f --- /dev/null +++ b/gcc/testsuite/gcc.c-torture/execute/pr40657.c @@ -0,0 +1,23 @@ +/* Verify that that Thumb-1 epilogue size optimization does not clobber the + return value. */ + +long long v = 0x123456789abc; + +__attribute__((noinline)) void bar (int *x) +{ + asm volatile ("" : "=m" (x) ::); +} + +__attribute__((noinline)) long long foo() +{ + int x; + bar(&x); + return v; +} + +int main () +{ + if (foo () != v) + abort (); + exit (0); +} -- cgit v1.2.3
