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	2b1e7dc1cc	Arena refactor: moves cleanup list into regular blocks (#277 ) * WIP. * WIP. * Tests are passing. * Recover some perf: LIKELY doesn't propagate through functions. :( * Added some more benchmarks. * Simplify & optimize upb_arena_realloc(). * Only add owned blocks to the freelist. * More optimization/simplification. * Re-fixed the bug. * Revert unintentional changes to parser.rl. * Revert Lua changes for now. * Revert the arena fuse changes for now. * Added last_size to the arena representation. * Fixed compile errors. * Fixed compile error and changed benchmarks to do one allocation.	5 years ago
Joshua Haberman	08b6d2d6fd	Rewrite of the decoder (#263 ) New code is smaller (in both source size and compiled size) and faster. # Speed The decoder speeds up on all machines I tested, though the amount of speedup varies. I was only able to test Intel CPUs. ### Linux Desktop ``` CPU: Intel(R) Core(TM) i7-8700K CPU @ 3.70GHz OS: Linux name old time/op new time/op delta CreateArena 4.72ns ± 0% 4.93ns ± 0% +4.47% (p=0.000 n=11+11) ParseDescriptor 12.4µs ± 1% 9.1µs ± 1% -26.65% (p=0.000 n=11+11) ``` ### Mac Laptop ``` CPU: Intel(R) Core(TM) i7-8850H CPU @ 2.60GHz OS: macOS name old time/op new time/op delta CreateArena 5.33ns ± 3% 5.58ns ± 2% +4.69% (p=0.000 n=12+12) ParseDescriptor 15.0µs ± 2% 11.9µs ± 2% -20.20% (p=0.000 n=12+12) ``` ### Linux Workstation ``` CPU: Intel(R) Xeon(R) Gold 6154 CPU @ 3.00GHz OS: Linux name old time/op new time/op delta CreateArena 5.29ns ± 0% 5.52ns ± 0% +4.37% (p=0.000 n=10+12) ParseDescriptor 18.6µs ± 0% 16.4µs ± 0% -11.54% (p=0.000 n=12+12) ``` # Size A few source files grow marginally because of some arena functionality moved inline.
