From 013de2b5ab8094d2c82a2771f3d143eeb656eda9 Mon Sep 17 00:00:00 2001 From: Lasse Collin Date: Tue, 3 Nov 2015 20:55:45 +0200 Subject: liblzma: Rename lzma_presets.c back to lzma_encoder_presets.c. It would be too annoying to update other build systems just because of this. --- src/liblzma/lzma/Makefile.inc | 2 +- src/liblzma/lzma/lzma_encoder_presets.c | 64 +++++++++++++++++++++++++++++++++ src/liblzma/lzma/lzma_presets.c | 64 --------------------------------- 3 files changed, 65 insertions(+), 65 deletions(-) create mode 100644 src/liblzma/lzma/lzma_encoder_presets.c delete mode 100644 src/liblzma/lzma/lzma_presets.c (limited to 'src') diff --git a/src/liblzma/lzma/Makefile.inc b/src/liblzma/lzma/Makefile.inc index 0c8cd380..506b328c 100644 --- a/src/liblzma/lzma/Makefile.inc +++ b/src/liblzma/lzma/Makefile.inc @@ -11,7 +11,7 @@ liblzma_la_SOURCES += lzma/lzma_common.h if COND_FILTER_LZMA1 liblzma_la_SOURCES += \ - lzma/lzma_presets.c + lzma/lzma_encoder_presets.c endif if COND_ENCODER_LZMA1 diff --git a/src/liblzma/lzma/lzma_encoder_presets.c b/src/liblzma/lzma/lzma_encoder_presets.c new file mode 100644 index 00000000..711df025 --- /dev/null +++ b/src/liblzma/lzma/lzma_encoder_presets.c @@ -0,0 +1,64 @@ +/////////////////////////////////////////////////////////////////////////////// +// +/// \file lzma_encoder_presets.c +/// \brief Encoder presets +/// \note xz needs this even when only decoding is enabled. +// +// Author: Lasse Collin +// +// This file has been put into the public domain. +// You can do whatever you want with this file. +// +/////////////////////////////////////////////////////////////////////////////// + +#include "common.h" + + +extern LZMA_API(lzma_bool) +lzma_lzma_preset(lzma_options_lzma *options, uint32_t preset) +{ + const uint32_t level = preset & LZMA_PRESET_LEVEL_MASK; + const uint32_t flags = preset & ~LZMA_PRESET_LEVEL_MASK; + const uint32_t supported_flags = LZMA_PRESET_EXTREME; + + if (level > 9 || (flags & ~supported_flags)) + return true; + + options->preset_dict = NULL; + options->preset_dict_size = 0; + + options->lc = LZMA_LC_DEFAULT; + options->lp = LZMA_LP_DEFAULT; + options->pb = LZMA_PB_DEFAULT; + + static const uint8_t dict_pow2[] + = { 18, 20, 21, 22, 22, 23, 23, 24, 25, 26 }; + options->dict_size = UINT32_C(1) << dict_pow2[level]; + + if (level <= 3) { + options->mode = LZMA_MODE_FAST; + options->mf = level == 0 ?
