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/ssa-pre-27.c | 29 +++++++++++++++++++++++++++++ 1 file changed, 29 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/tree-ssa/ssa-pre-27.c (limited to 'gcc/testsuite/gcc.dg/tree-ssa/ssa-pre-27.c') diff --git a/gcc/testsuite/gcc.dg/tree-ssa/ssa-pre-27.c b/gcc/testsuite/gcc.dg/tree-ssa/ssa-pre-27.c new file mode 100644 index 000000000..1d60a3013 --- /dev/null +++ b/gcc/testsuite/gcc.dg/tree-ssa/ssa-pre-27.c @@ -0,0 +1,29 @@ +/* { dg-do compile } */ +/* { dg-options "-O2 -fdump-tree-pre" } */ + +int foo (int i, int j, int b) +{ + int res = 0; + if (b) + res = i/j; + /* We should insert the possibly trapping i/j. */ + res += i/j; + return res; +} + +extern void bar (void); +int foo2 (int i, int j, int b) +{ + int res = 0; + if (b) + res = i/j; + /* But we fail so here because of the possibly not returning + call in the same basic-block. */ + res += i/j; + bar (); + return res; +} + +/* { dg-final { scan-tree-dump-times "# prephitmp" 1 "pre" } } */ +/* { dg-final { scan-tree-dump-times "# prephitmp" 2 "pre" { xfail *-*-* } } } */ +/* { dg-final { cleanup-tree-dump "pre" } } */ -- cgit v1.2.3
