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/pr41783.c | 20 ++++++++++++++++++++ 1 file changed, 20 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/pr41783.c (limited to 'gcc/testsuite/gcc.dg/pr41783.c') diff --git a/gcc/testsuite/gcc.dg/pr41783.c b/gcc/testsuite/gcc.dg/pr41783.c new file mode 100644 index 000000000..cae066be6 --- /dev/null +++ b/gcc/testsuite/gcc.dg/pr41783.c @@ -0,0 +1,20 @@ +/* { dg-do compile } */ +/* { dg-options "-O3 -fdump-tree-pre" } */ +int db[100]; +int a_global_var, fact; +int main() +{ + int i,j=0; + do + { + for (i=0; i<100; ++i) + db[i] = i; + fact = a_global_var * i; + } + while (j++ < 100); +} +/* We want to have exactly one load (not two) from a_global_var, + and we want that load to be into a PRE temporary. */ +/* { dg-final { scan-tree-dump-times "= a_global_var;" 1 "pre" } } */ +/* { dg-final { scan-tree-dump "pretmp\[^\\n\]* = a_global_var;" "pre" } } */ +/* { dg-final { cleanup-tree-dump "pre" } } */ -- cgit v1.2.3
