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/execute/ffs-2.c | 44 +++++++++++++++++++++++++++++ 1 file changed, 44 insertions(+) create mode 100644 gcc/testsuite/gcc.c-torture/execute/ffs-2.c (limited to 'gcc/testsuite/gcc.c-torture/execute/ffs-2.c') diff --git a/gcc/testsuite/gcc.c-torture/execute/ffs-2.c b/gcc/testsuite/gcc.c-torture/execute/ffs-2.c new file mode 100644 index 000000000..ae246cebf --- /dev/null +++ b/gcc/testsuite/gcc.c-torture/execute/ffs-2.c @@ -0,0 +1,44 @@ +struct + { + int input; + int output; + } +ffstesttab[] = + { +#if __INT_MAX__ >= 2147483647 + /* at least 32-bit integers */ + { 0x80000000, 32 }, + { 0xa5a5a5a5, 1 }, + { 0x5a5a5a5a, 2 }, + { 0xcafe0000, 18 }, +#endif +#if __INT_MAX__ >= 32767 + /* at least 16-bit integers */ + { 0x8000, 16 }, + { 0xa5a5, 1 }, + { 0x5a5a, 2 }, + { 0x0ca0, 6 }, +#endif +#if __INT_MAX__ < 32767 +#error integers are too small +#endif + }; + +#define NFFSTESTS (sizeof (ffstesttab) / sizeof (ffstesttab[0])) + +extern void abort (void); +extern void exit (int); + +int +main (void) +{ + int i; + + for (i = 0; i < NFFSTESTS; i++) + { + if (__builtin_ffs (ffstesttab[i].input) != ffstesttab[i].output) + abort (); + } + + exit (0); +} -- cgit v1.2.3
