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/tree-ssa/pr14814.c | 22 ++++++++++++++++++++++ 1 file changed, 22 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/tree-ssa/pr14814.c (limited to 'gcc/testsuite/gcc.dg/tree-ssa/pr14814.c') diff --git a/gcc/testsuite/gcc.dg/tree-ssa/pr14814.c b/gcc/testsuite/gcc.dg/tree-ssa/pr14814.c new file mode 100644 index 000000000..eb3605515 --- /dev/null +++ b/gcc/testsuite/gcc.dg/tree-ssa/pr14814.c @@ -0,0 +1,22 @@ +/* { dg-do compile } */ +/* { dg-options "-O2 -fno-tree-sra -fdump-tree-forwprop2" } */ + +struct YY { + double e[3]; }; + +static inline double *y(struct YY* this_1) { return &this_1->e[1]; } + +struct XX { + struct YY v; + }; + +static inline struct YY direction (const struct XX* this_1) { return this_1->v;} + +int foo(const struct XX* r) { + struct YY t = direction(r); + if (*y(&t) < 0.000001) return 0; + return 1; +} + +/* { dg-final { scan-tree-dump-times "&" 0 "forwprop2" } } */ +/* { dg-final { cleanup-tree-dump "forwprop2" } } */ -- cgit v1.2.3
