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/pr30665-2.c | 57 ++++++++++++++++++++++++++++++++ 1 file changed, 57 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/torture/pr30665-2.c (limited to 'gcc/testsuite/gcc.dg/torture/pr30665-2.c') diff --git a/gcc/testsuite/gcc.dg/torture/pr30665-2.c b/gcc/testsuite/gcc.dg/torture/pr30665-2.c new file mode 100644 index 000000000..a2cbf024c --- /dev/null +++ b/gcc/testsuite/gcc.dg/torture/pr30665-2.c @@ -0,0 +1,57 @@ +/* PR target/30665: bug in cris.md peephole2 condition. + Original reduced testcase (fails on 3.2.1 derivate, not on trunk). */ +/* { dg-do run } */ + +extern void abort (void); +extern void exit (int); + +struct t +{ + unsigned int a : 12; + unsigned int b : 12; + unsigned int dummy1 : 8; +}; + +struct area +{ + int xa; + int xb; +}; + +struct c +{ + struct area ii; +}; + +static struct c c; + +void __attribute__ ((__noinline__)) g(int a) +{ + if (a != 79) + abort (); +} + +void __attribute__ ((__noinline__)) h(struct t tt) +{ + if (tt.a != 20 || tt.b != 79) + abort (); +} + +void __attribute__ ((__noinline__)) s(void); + +int main(int argc, char **argv) +{ + c.ii.xa = 20; + c.ii.xb = 79; + + s(); + + exit (0); +} + +void __attribute__ ((__noinline__)) s(void) +{ + struct t ii_x = { .a = c.ii.xa, .b = c.ii.xb }; + g(c.ii.xb); + h(ii_x); +} -- cgit v1.2.3
