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

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.

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

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

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.
