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/20030807-5.c | 39 ++++++++++++++++++++++++++++++ 1 file changed, 39 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/tree-ssa/20030807-5.c (limited to 'gcc/testsuite/gcc.dg/tree-ssa/20030807-5.c') diff --git a/gcc/testsuite/gcc.dg/tree-ssa/20030807-5.c b/gcc/testsuite/gcc.dg/tree-ssa/20030807-5.c new file mode 100644 index 000000000..424b5583b --- /dev/null +++ b/gcc/testsuite/gcc.dg/tree-ssa/20030807-5.c @@ -0,0 +1,39 @@ +/* { dg-do compile } */ +/* { dg-options "-O1 -fdump-tree-dom2" } */ + +extern void abort (void); +struct rtx_def; +typedef struct rtx_def *rtx; + + +struct rtx_def +{ + + int code; + unsigned int unchanging:1; + +}; +static rtx current_sym_addr; + +int +foo () +{ + if (current_sym_addr->code == 42 + && (({ + rtx _rtx = current_sym_addr; + if (((_rtx)->code) != 42) + abort (); + _rtx;} + )->unchanging)) + return 0; +} + +/* There should be precisely one load of ->code.
