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/ipa/ipa-pta-3.c | 28 ++++++++++++++++++++++++++++ 1 file changed, 28 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/ipa/ipa-pta-3.c (limited to 'gcc/testsuite/gcc.dg/ipa/ipa-pta-3.c') diff --git a/gcc/testsuite/gcc.dg/ipa/ipa-pta-3.c b/gcc/testsuite/gcc.dg/ipa/ipa-pta-3.c new file mode 100644 index 000000000..e73db1c95 --- /dev/null +++ b/gcc/testsuite/gcc.dg/ipa/ipa-pta-3.c @@ -0,0 +1,28 @@ +/* { dg-do run } */ +/* { dg-options "-O2 -fipa-pta -fdump-ipa-pta-details -fdump-tree-fre-details" } */ + +static int __attribute__((noinline,noclone)) +foo (int *p, int *q) +{ + *p = 1; + *q = 0; + return *p; +} + +extern void abort (void); + +int main() +{ + int a, b; + if (foo (&a, &b) != 1) + abort (); + return 0; +} + +/* Verify we can disambiguate *p and *q in foo. */ + +/* { dg-final { scan-ipa-dump "foo.arg0 = &a" "pta" } } */ +/* { dg-final { scan-ipa-dump "foo.arg1 = &b" "pta" } } */ +/* { dg-final { scan-tree-dump "Replaced \\\*p_1\\\(D\\\) with 1" "fre" } } */ +/* { dg-final { cleanup-tree-dump "fre" } } */ +/* { dg-final { cleanup-ipa-dump "pta" } } */ -- cgit v1.2.3
