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/torture/pta-callused-1.c | 25 +++++++++++++++++++++++++ 1 file changed, 25 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/torture/pta-callused-1.c (limited to 'gcc/testsuite/gcc.dg/torture/pta-callused-1.c') diff --git a/gcc/testsuite/gcc.dg/torture/pta-callused-1.c b/gcc/testsuite/gcc.dg/torture/pta-callused-1.c new file mode 100644 index 000000000..dfbde86c6 --- /dev/null +++ b/gcc/testsuite/gcc.dg/torture/pta-callused-1.c @@ -0,0 +1,25 @@ +/* { dg-do run } */ +/* { dg-options "-fdump-tree-alias" } */ +/* { dg-skip-if "" { *-*-* } { "-O0" } { "" } } */ + +volatile int i; +int ** __attribute__((noinline,pure)) foo(int **p) { i; return p; } +int bar(void) +{ + int i = 0, j = 1; + int *p, **q; + p = &i; + q = foo(&p); + *q = &j; + return *p; +} +extern void abort (void); +int main() +{ + if (bar() != 1) + abort (); + return 0; +} + +/* { dg-final { scan-tree-dump "p.._., points-to vars: { i j }" "alias" } } */ +/* { dg-final { cleanup-tree-dump "alias" } } */ -- cgit v1.2.3
