From cf6cc8aaebfe6d3afb1fab0760fe3f72d670bb1a Mon Sep 17 00:00:00 2001 From: ossman_ Date: Mon, 29 Jun 2009 11:20:42 +0000 Subject: Clean up SIMD glue code The SIMD glue code has gotten a bit #ifdef heavy so clean it up by having one file for each possible SIMD arch. This also allows a simplification of the x86_64 code as SSE/SSE2 is always known to exist on that arch. git-svn-id: svn://svn.code.sf.net/p/libjpeg-turbo/code/trunk@49 632fc199-4ca6-4c93-a231-07263d6284db --- simd/Makefile.am | 14 +- simd/jsimd_i386.c | 956 +++++++++++++++++++++++++++++++++++++++++++++++++++ simd/jsimd_x86_64.c | 680 ++++++++++++++++++++++++++++++++++++ simd/jsimdcpu-64.asm | 95 ----- 4 files changed, 1645 insertions(+), 100 deletions(-) create mode 100644 simd/jsimd_i386.c create mode 100644 simd/jsimd_x86_64.c delete mode 100644 simd/jsimdcpu-64.asm (limited to 'simd') diff --git a/simd/Makefile.am b/simd/Makefile.am index da7d684..8e7469f 100644 --- a/simd/Makefile.am +++ b/simd/Makefile.am @@ -4,11 +4,12 @@ BUILT_SOURCES = jsimdcfg.inc EXTRA_DIST = nasm_lt.sh -if WITH_SIMD64 +if SIMD_X86_64 -libsimd_la_SOURCES = jsimd.h jsimdcfg.inc.h \ +libsimd_la_SOURCES = jsimd_x86_64.c \ + jsimd.h jsimdcfg.inc.h \ jsimdext.inc jcolsamp.inc jdct.inc \ - jsimdcpu-64.asm jfsseflt-64.asm \ + jfsseflt-64.asm \ jccolss2-64.asm jdcolss2-64.asm \ jcsamss2-64.asm jdsamss2-64.asm jdmerss2-64.asm \ jcqnts2i-64.asm jfss2fst-64.asm jfss2int-64.asm \ @@ -19,9 +20,12 @@ jccolss2-64.lo: jcclrss2-64.asm jdcolss2-64.lo: jdclrss2-64.asm jdmerss2-64.lo: jdmrgss2-64.asm -else +endif + +if SIMD_I386 -libsimd_la_SOURCES = jsimd.h jsimdcfg.inc.h \ +libsimd_la_SOURCES = jsimd_i386.c \ + jsimd.h jsimdcfg.inc.h \ jsimdext.inc jcolsamp.inc jdct.inc \ jsimdcpu.asm \ jccolmmx.asm jdcolmmx.asm \ diff --git a/simd/jsimd_i386.c b/simd/jsimd_i386.c new file mode 100644 index 0000000..751fe2d --- /dev/null +++ b/simd/jsimd_i386.c @@ -0,0 +1,956 @@ +/* + * jsimd_i386.c + * + * Copyright 2009 Pierre Ossman for Cendio AB + * Copyright 2009 D.
