[PATCH 2/5] SIMD: remove extra space
Most libFLAC code don't have a space between if and a parenthesis, so the patch removes them from lpc_intrin_sseNN.c files. -------------- next part -------------- A non-text attachment was scrubbed...

[PATCH 5/5] SIMD: remove outdated SSE2 code
This patch removes FLAC__lpc_restore_signal_16_intrin_sse2(). It's faster than C code, but not faster than MMX-accelerated ASM functions. It's also slower than the new SSE4.1 functions that were added by the previous patch. So this function wasn't very useful before, and now it's even less useful. I don't see a reason to keep it. -------------- next part -------------- A

[PATCH 4/5] SIMD: accelerate decoding of 16-bit FLAC
This patch adds 2 new functions, FLAC__lpc_restore_signal_intrin_sse41() and FLAC__lpc_restore_signal_16_intrin_sse41(). The decoding speed of Subset-compatible 16-bit FLAC files is slightly increased on SSE4.1-compatible CPUs. -------------- next part -------------- A non-text attachment was scrubbed...

[PATCH 3/5] SIMD: accelerate decoding of some 24-bit FLAC
This patch accelerates decoding of non-Subset 24-bit FLAC files (where lpc_order > 12). (The improved function is FLAC__lpc_restore_signal_wide_intrin_sse41(). It requires SSE4.1 and it's used only by 32-bit libFLAC) -------------- next part -------------- A non-text attachment was scrubbed...

PATCH: x86-64 support and SSE intrinscis code
It's not possible to use ia32/*.nasm code in 64-bit compiles. There's still no 64-bit asm code in FLAC. I'm not familiar with asm too, so I wrote SSE-accelerated code using intrinsics. This code uses two new preprocessor macros: FLAC__CPU_X86_64 (analogous to FLAC__CPU_IA32) and FLAC__HAS_X86INTRIN (analogous to FLAC__HAS_NASM) Patch for cpu.c/cpu.h adds CPU features (sse3, ssse3)

Broken build on musl libc
Patch is here: https://github.com/openwrt/packages/commit/1263599f96f13f11d719ce336dfb6a639b32de98 . Probably needs to be modified for inclusion into mainline.

[PATCH] cpu.h: add defines for clang
Currently cpu.h lacks FLAC__SSE_TARGET and FLAC__SSEnn_SUPPORTED macros for clang. I added them, but I cannot properly test them as I can't get compiled flac.exe under Windows (don't know how to setup clang under MSYS2). If somebody has working clang, please test this patch. Does it affect en/decoding speed? Or at least, dows it affect disassembly of functions such as

How to check for 64-bit CPU?
In stream_encoder.c there's the following code: #if defined FLAC__CPU_X86_64 /* and other 64-bit arch, too */ if(mean <= 0x80000000/512) { /* 512: more or less optimal for both 16- and 24-bit input */ #else if(mean <= 0x80000000/8) { /* 32-bit arch: use 32-bit math if possible */ #endif A) How to properly check for 64-bit architectures?

[PATCH] PPC/Altivec removal
This set of patches removes PPC/Altivec code from FLAC. I decided to split the patch into 5 parts to make it more simple: 1) removes FLAC__lpc_restore_signal_asm_ppc_altivec_16* from lpc.h and stream_decoder.c 2) removes PPC-specific code from cpu.c and cpu.h 3) removes PPC stuff from libFLAC/Makefile.lite and build/*.mk 4) removes as/gas/PPC-specific stuff from configure.ac and

PATCH: modify/add intrinsics code
The patch does the following: 1. splits lpc_x86intrin.c to lpc_intrin_sse.c and lpc_intrin_sse2.c 2. adds FLAC__lpc_compute_residual_from_qlp_coefficients_intrin_sse2() function to lpc_intrin_sse2.c 3. adds lpc_intrin_sse41.c with two ..._wide_intrin_sse41() functions (useful for 24-bit en-/decoding) 4. adds precompute_partition_info_sums_intrin_sse2() / ...ssse3() and disables
