Joshua Haberman	f2d826b9f3	Got rid of floating-point division in table init. Ideally we would get rid of all floating-point operations in table.c, but that's a job for another day.	4 years ago
Joshua Haberman	723cd8ffc1	Added wyhash code and LICENSE, and removed temporary benchmark.	4 years ago
Joshua Haberman	15e20636c3	Merge branch 'master' into optdefload	4 years ago

Joshua Haberman	e8f9eac68c	Added #defines UPB_ENABLE_FASTTABLE and UPB_TRY_ENABLE_FASTTABLE. These control whether fasttable decoding is on.	4 years ago

Joshua Haberman	a0d16e7073	Added a few missing copts, and made some functions proper prototypes.	4 years ago
Joshua Haberman	558315a1c3	Added COPTS to :port.	4 years ago
Joshua Haberman	7e5bd65098	Plumbed copts (including the crucial -std=c99) to upb_proto_library() aspect.	4 years ago
Joshua Haberman	8f3ee80d46	Drop C89/C90 support and MSVC prior to Visual Studio 2015. upb previously attempted to support C89 and pre-2015 versions of Visual Studio. This was to support older compilers with limited C99 support (particularly MSVC). But as of last August, even gRPC has dropped support for MSVC prior to 2015 `c87276d058` Therefore it seems safe for upb to no longer attempt C89 support (we were already not truly C89 compliant, with our use of "bool"). We now explicitly require C99 or greater and MSVC 2015 or greater. This cleaned up port_def.inc a fair bit. I took the chance to also remove some obsolete macros.	4 years ago

Joshua Haberman	46eb82467a	Added comment to decode_fast.h.	4 years ago
Joshua Haberman	bd9f8f580d	Fixed a few bugs with the fast decoder. 1. For long tags we were putting table entries in the wrong slot. 2. For repeated strings, when the buffer flipped to no longer alias we were failing to notice and kept aliasing anyway.	4 years ago
Joshua Haberman	3eba47914b	Allocate hasbits and table slots in "hotness" order. Without a profile, we assume that fields with smaller numbers are hotter.	4 years ago

Joshua Haberman	86d9908c55	Fastdecode support for packed fields. This is not very optimized yet. There is a lot of room to optimize it further.	4 years ago

Joshua Haberman	48689df72e	Eliminated bounds checks inside parsing a field. Each field parser gets 16 bytes of slop. This requires using a patch buffer at end-of-buffer. This addes 80% of what is needed to support a pull parser with a data callback, since the main parser is now tolerant to buffer flips.
