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/gnat.dg/sse_nolib.adb | 50 +++++++++++++++++++++++++++++++++++++ 1 file changed, 50 insertions(+) create mode 100644 gcc/testsuite/gnat.dg/sse_nolib.adb (limited to 'gcc/testsuite/gnat.dg/sse_nolib.adb') diff --git a/gcc/testsuite/gnat.dg/sse_nolib.adb b/gcc/testsuite/gnat.dg/sse_nolib.adb new file mode 100644 index 000000000..a0aa720f0 --- /dev/null +++ b/gcc/testsuite/gnat.dg/sse_nolib.adb @@ -0,0 +1,50 @@ +-- { dg-do run { target i?86-*-* x86_64-*-* } } +-- { dg-options "-O1 -msse" } +-- { dg-require-effective-target sse_runtime } + +with Ada.Unchecked_Conversion; + +procedure SSE_Nolib is + + -- Base vector type definitions + + package SSE_Types is + VECTOR_ALIGN : constant := 16; + VECTOR_BYTES : constant := 16; + + type m128 is private; + private + type m128 is array (1 .. 4) of Float; + for m128'Alignment use VECTOR_ALIGN; + pragma Machine_Attribute (m128, "vector_type"); + pragma Machine_Attribute (m128, "may_alias"); + end SSE_Types; + + use SSE_Types; + + -- Core operations + + function mm_add_ss (A, B : m128) return m128; + pragma Import (Intrinsic, mm_add_ss, "__builtin_ia32_addss"); + + -- User views / conversions or overlays + + type Vf32_View is array (1 .. 4) of Float; + for Vf32_View'Alignment use VECTOR_ALIGN; + + function To_m128 is new Ada.Unchecked_Conversion (Vf32_View, m128); + function To_m128 is new Ada.Unchecked_Conversion (m128, Vf32_View); + + X, Y, Z : M128; + + Vz : Vf32_View; + for Vz'Address use Z'Address; +begin + X := To_m128 ((1.0, 1.0, 2.0, 2.0)); + Y := To_m128 ((2.0, 2.0, 1.0, 1.0)); + Z := mm_add_ss (X, Y); + + if Vz /= (3.0, 1.0, 2.0, 2.0) then + raise Program_Error; + end if; +end SSE_Nolib; -- cgit v1.2.3
