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/pta-ptrarith-1.c | 26 ++++++++++++++++++++++++++ 1 file changed, 26 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/tree-ssa/pta-ptrarith-1.c (limited to 'gcc/testsuite/gcc.dg/tree-ssa/pta-ptrarith-1.c') diff --git a/gcc/testsuite/gcc.dg/tree-ssa/pta-ptrarith-1.c b/gcc/testsuite/gcc.dg/tree-ssa/pta-ptrarith-1.c new file mode 100644 index 000000000..2a60e1daa --- /dev/null +++ b/gcc/testsuite/gcc.dg/tree-ssa/pta-ptrarith-1.c @@ -0,0 +1,26 @@ +/* { dg-do compile } */ +/* { dg-options "-O2 -fno-tree-forwprop -fno-tree-ccp -fdump-tree-ealias" } */ + +extern void abort (void); +struct X { + int *p; + int *q; + int *r; +}; +int __attribute__((noinline)) +foo(int i, int j, int k, int off) +{ + struct X x; + int **p, *q; + x.p = &i; + x.q = &j; + x.r = &k; + p = &x.q; + p += 1; + /* *p points to { k } */ + q = *p; + return *q; +} + +/* { dg-final { scan-tree-dump "q_., points-to vars: { k }" "ealias" } } */ +/* { dg-final { cleanup-tree-dump "ealias" } } */ -- cgit v1.2.3
