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-ffs-1.c | 17 +++++++++++++++++ 1 file changed, 17 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/builtin-ffs-1.c (limited to 'gcc/testsuite/gcc.dg/builtin-ffs-1.c') diff --git a/gcc/testsuite/gcc.dg/builtin-ffs-1.c b/gcc/testsuite/gcc.dg/builtin-ffs-1.c new file mode 100644 index 000000000..2bf0e9873 --- /dev/null +++ b/gcc/testsuite/gcc.dg/builtin-ffs-1.c @@ -0,0 +1,17 @@ +/* { dg-do compile } */ +/* { dg-options "-O2" } */ + +extern int ffs (int) __asm ("__GI_ffs") __attribute__ ((nothrow, const)); + +int +ffsll (long long int i) +{ + unsigned long long int x = i & -i; + + if (x <= 0xffffffff) + return ffs (i); + else + return 32 + ffs (i >> 32); +} + +/* { dg-final { scan-assembler-not "\nffs\n|\nffs\[^a-zA-Z0-9_\]|\[^a-zA-Z0-9_\]ffs\n" } } */ -- cgit v1.2.3
