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/20040101-1.c | 30 ++++++++++++++++++++++++ 1 file changed, 30 insertions(+) create mode 100644 gcc/testsuite/gcc.c-torture/compile/20040101-1.c (limited to 'gcc/testsuite/gcc.c-torture/compile/20040101-1.c') diff --git a/gcc/testsuite/gcc.c-torture/compile/20040101-1.c b/gcc/testsuite/gcc.c-torture/compile/20040101-1.c new file mode 100644 index 000000000..baa0e4f93 --- /dev/null +++ b/gcc/testsuite/gcc.c-torture/compile/20040101-1.c @@ -0,0 +1,30 @@ +/* { dg-skip-if "not enough registers" { pdp11-*-* } { "-O[12s]" } { "" } } */ + +typedef unsigned short uint16_t; +typedef unsigned int uint32_t; + +#define CF (1<<0) +#define PF (1<<2) +#define AF (1<<4) +#define ZF (1<<6) +#define SF (1<<7) +#define OF (1<<11) + +#define EFLAGS_BITS (CF|PF|AF|ZF|SF|OF) + +void test16(uint16_t x, uint32_t eflags) +{ + uint16_t bsr_result; + uint32_t bsr_eflags; + uint16_t bsf_result; + uint32_t bsf_eflags; + + __asm volatile("" + : "=&r" (bsr_result), "=&r" (bsr_eflags) + : "r" (x), "i" (~EFLAGS_BITS), "r" (eflags)); + __asm volatile("" + : "=&r" (bsf_result), "=&r" (bsf_eflags) + : "r" (x), "i" (~EFLAGS_BITS), "r" (eflags)); + printf("%08x %04x bsrw %02x %08x bsfw %02x %08x\n", + x, eflags, bsr_result, bsr_eflags, bsf_result, bsf_eflags); +} -- cgit v1.2.3
