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/guality/pr45003-3.c | 31 +++++++++++++++++++++++++++++++ 1 file changed, 31 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/guality/pr45003-3.c (limited to 'gcc/testsuite/gcc.dg/guality/pr45003-3.c') diff --git a/gcc/testsuite/gcc.dg/guality/pr45003-3.c b/gcc/testsuite/gcc.dg/guality/pr45003-3.c new file mode 100644 index 000000000..3adc4f238 --- /dev/null +++ b/gcc/testsuite/gcc.dg/guality/pr45003-3.c @@ -0,0 +1,31 @@ +/* PR debug/45003 */ +/* { dg-do run { target { x86_64-*-* && lp64 } } } */ +/* { dg-options "-g" } */ + +int __attribute__((noinline)) +foo (unsigned short *p) +{ + int a = (short) *p; + asm volatile ("nop" : : "D" ((int) *p)); + asm volatile ("nop" : : "D" ((int) *p)); /* { dg-final { gdb-test 10 "a" "-32648" } } */ + return 0; +} + +int __attribute__((noinline)) +bar (short *p) +{ + unsigned int a = (unsigned short) *p; + asm volatile ("nop" : : "D" ((unsigned int) *p)); + asm volatile ("nop" : : "D" ((unsigned int) *p)); /* { dg-final { gdb-test 19 "a" "0x8078" } } */ + return 0; +} + +int +main () +{ + unsigned short us = 0x8078; + foo (&us); + short s = -32648; + bar (&s); + return 0; +} -- cgit v1.2.3
