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/builtin-bswap-4.c | 60 ++++++++++++++++++++++++++++++++++ 1 file changed, 60 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/builtin-bswap-4.c (limited to 'gcc/testsuite/gcc.dg/builtin-bswap-4.c') diff --git a/gcc/testsuite/gcc.dg/builtin-bswap-4.c b/gcc/testsuite/gcc.dg/builtin-bswap-4.c new file mode 100644 index 000000000..03e190ad7 --- /dev/null +++ b/gcc/testsuite/gcc.dg/builtin-bswap-4.c @@ -0,0 +1,60 @@ +/* { dg-do run } */ +/* { dg-require-effective-target stdint_types } */ +/* { dg-options "-Wall" } */ + +#include + +#define MAKE_FUN(suffix, type) \ + type my_bswap##suffix(type x) { \ + type result = 0; \ + int shift; \ + for (shift = 0; shift < 8 * sizeof (type); shift += 8) \ + { \ + result <<= 8; \ + result |= (x >> shift) & 0xff; \ + } \ + return result; \ + } \ + +MAKE_FUN(32, uint32_t); +MAKE_FUN(64, uint64_t); + +extern void abort (void); + +#define NUMS32 \ + { \ + 0x00000000UL, \ + 0x11223344UL, \ + 0xffffffffUL, \ + } + +#define NUMS64 \ + { \ + 0x0000000000000000ULL, \ + 0x1122334455667788ULL, \ + 0xffffffffffffffffULL, \ + } + +uint32_t uint32_ts[] = + NUMS32; + +uint64_t uint64_ts[] = + NUMS64; + +#define N(table) (sizeof (table) / sizeof (table[0])) + +int +main (void) +{ + int i; + + for (i = 0; i < N(uint32_ts); i++) + if (__builtin_bswap32 (uint32_ts[i]) != my_bswap32 (uint32_ts[i])) + abort (); + + for (i = 0; i < N(uint64_ts); i++) + if (__builtin_bswap64 (uint64_ts[i]) != my_bswap64 (uint64_ts[i])) + abort (); + + return 0; +} -- cgit v1.2.3
