Zoltan Szabadka ca3a7a98f2 Use FastLog2() instead of log() in BitsEntropy(). 2015-03-30 13:41:52 +02:00

Zoltan Szabadka 8f3092a0b1 Add some missing state transitions to DecodeContextMap(). 
Update the states in DecodeContextMap to the next one,
else it would continue at the wrong spot if exactly there
the partial input is split.

Add a faster but less dense compression mode.
 2015-03-27 14:28:32 +01:00
Zoltan Szabadka 534654def1 Add a faster but less dense compression mode. 
The new mode can be used by setting the greedy_block_split
field of BrotliParams to true.

This commit moves all the meta-block processing code
into its own library and moves the meta-block encoding
code to brotli_bit_stream.cc from encode.cc

Dmitry Shachnev 5da7e37a06 Makefile fixes and cleanups 
- Distinguish between CC/CFLAGS, CPP/CPPFLAGS and CXX/CXXFLAGS.
  Do not store compiler flags in CPPFLAGS, which is for preprocessor,
  and do not try to link files using a preprocessor.
- Use COMMON_FLAGS for flags that are for both C and C++.
- Drop -m64 flag which is wrong on 32-bit systems.
- Use $(MAKE) instead of make, so that parallel building works.

Fix encoder compilation error on MSVS 2010.
 2015-02-27 16:12:54 +01:00
Zoltan Szabadka fab601e81f Fix encoder compilation error on MSVS 2010. 
As reported by @anthrotype, log2() is missing from MSVS 2010.
This patch uses log() and a multiplication in FastLog2()
for _MSV_VER <= 1600 and uses FastLog2() in literal_cost.cc
instead of log2().

Implement a 32-bit bitstream decoder + visual studio support
 2015-02-25 18:40:17 +01:00
Zoltan Szabadka f0b88cbcdb Fixes to the encoder to support visual studio. 
Changes suggested by @r-lyeh and @anthrotype.

 - Use a portable simple PRNG instead of rand_r()
 - add missing <assert.h> include
 - disambiguate log2() argument type
 - remove endian.h include from write_bits.h

Zoltan Szabadka 6da0c5c992 Implement a 32-bit bitstream decoder. 
The 64-bit bitstream decoder seems to have portability problems
with emscripten/asm.js as it does not compile into working code.
