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.c-torture/compile/pr21021.c | 19 +++++++++++++++++++ 1 file changed, 19 insertions(+) create mode 100644 gcc/testsuite/gcc.c-torture/compile/pr21021.c (limited to 'gcc/testsuite/gcc.c-torture/compile/pr21021.c') diff --git a/gcc/testsuite/gcc.c-torture/compile/pr21021.c b/gcc/testsuite/gcc.c-torture/compile/pr21021.c new file mode 100644 index 000000000..b74821630 --- /dev/null +++ b/gcc/testsuite/gcc.c-torture/compile/pr21021.c @@ -0,0 +1,19 @@ +/* PR tree-optimization/21021 + + The front end produces a comparison of mismatched types, namely an + integer and a pointer, causing VRP to compute TYPE_MAX_VALUE for a + pointer, which we cannot. */ + +extern void *bar (void); + +int +foo (unsigned int *p, unsigned int *q) +{ + const void *r = bar (); + + if (r >= (const void *) *p + && r < (const void *) *q) + return 1; + + return 0; +} -- cgit v1.2.3
