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/lto/20110201-1_0.c | 19 +++++++++++++++++++ 1 file changed, 19 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/lto/20110201-1_0.c (limited to 'gcc/testsuite/gcc.dg/lto/20110201-1_0.c') diff --git a/gcc/testsuite/gcc.dg/lto/20110201-1_0.c b/gcc/testsuite/gcc.dg/lto/20110201-1_0.c new file mode 100644 index 000000000..f5d335572 --- /dev/null +++ b/gcc/testsuite/gcc.dg/lto/20110201-1_0.c @@ -0,0 +1,19 @@ +/* { dg-lto-do run } */ +/* { dg-lto-options { { -O0 -flto } } } */ +/* { dg-extra-ld-options "-O2 -ffast-math -fuse-linker-plugin" } */ +/* { dg-require-linker-plugin "" } */ + +/* We require a linker plugin because otherwise we'd need to link + against libm which we are not sure here has cabs on all targets. + This is because collect2 invokes ld on the -O0 object code + which does not have folded cabs. */ + +double cabs(_Complex double); +double __attribute__((used)) +foo (_Complex double x, int b) +{ + if (b) + x = 0; + return cabs(x); +} +int main() { return 0; } -- cgit v1.2.3
