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.target/powerpc/ppc-fma-2.c | 183 +++++++++++++++++++++++++++ 1 file changed, 183 insertions(+) create mode 100644 gcc/testsuite/gcc.target/powerpc/ppc-fma-2.c (limited to 'gcc/testsuite/gcc.target/powerpc/ppc-fma-2.c') diff --git a/gcc/testsuite/gcc.target/powerpc/ppc-fma-2.c b/gcc/testsuite/gcc.target/powerpc/ppc-fma-2.c new file mode 100644 index 000000000..111b9cb09 --- /dev/null +++ b/gcc/testsuite/gcc.target/powerpc/ppc-fma-2.c @@ -0,0 +1,183 @@ +/* { dg-do compile { target { powerpc*-*-* } } } */ +/* { dg-skip-if "" { powerpc*-*-darwin* } { "*" } { "" } } */ +/* { dg-require-effective-target powerpc_vsx_ok } */ +/* { dg-options "-O3 -ftree-vectorize -mcpu=power7 -ffast-math -ffp-contract=off" } */ +/* { dg-final { scan-assembler-times "xvmadd" 2 } } */ +/* { dg-final { scan-assembler-times "xsmadd" 1 } } */ +/* { dg-final { scan-assembler-times "fmadds" 1 } } */ +/* { dg-final { scan-assembler-times "xvmsub" 2 } } */ +/* { dg-final { scan-assembler-times "xsmsub" 1 } } */ +/* { dg-final { scan-assembler-times "fmsubs" 1 } } */ +/* { dg-final { scan-assembler-times "xvnmadd" 2 } } */ +/* { dg-final { scan-assembler-times "xsnmadd" 1 } } */ +/* { dg-final { scan-assembler-times "fnmadds" 1 } } */ +/* { dg-final { scan-assembler-times "xvnmsub" 2 } } */ +/* { dg-final { scan-assembler-times "xsnmsub" 1 } } */ +/* { dg-final { scan-assembler-times "fnmsubs" 1 } } */ + +/* Only the functions calling the bulitin should generate an appropriate (a * + b) + c instruction. */ + +double +builtin_fma (double b, double c, double d) +{ + return __builtin_fma (b, c, d);
