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/pr20739.c | 24 ++++++++++++++++++++++++ 1 file changed, 24 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/tree-ssa/pr20739.c (limited to 'gcc/testsuite/gcc.dg/tree-ssa/pr20739.c') diff --git a/gcc/testsuite/gcc.dg/tree-ssa/pr20739.c b/gcc/testsuite/gcc.dg/tree-ssa/pr20739.c new file mode 100644 index 000000000..c1e7b58e3 --- /dev/null +++ b/gcc/testsuite/gcc.dg/tree-ssa/pr20739.c @@ -0,0 +1,24 @@ +/* PR middle-end/20739 */ + +/* dg-do compile */ +/* dg-options "-O" */ + +/* We used to fail to compile this because gimplification dropped the + conversion that added the const qualifier to the sub-expression + involving baz, and then immediately noticed and reported its + absence. */ + +typedef struct +{ + char chars[5]; +} +baz_t; + +extern baz_t * baz; + +extern void foo (baz_t); +int +bar (const baz_t * ls) +{ + foo (ls == 0 ? *(&baz[0]) : *ls); +} -- cgit v1.2.3
