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.

Joshua Haberman	a6c54729df	Added UPB_ASSUME(), to work around warnings when optimization is enabled: upb/json/parser.rl: In function 'end_member.isra.150': bazel-out/k8-opt/bin/upb.c:5536:13: error: 'sel' may be used uninitialized in this function [-Werror=maybe-uninitialized] upb_func ret = (upb_func )h->table[s].func;	5 years ago
Joshua Haberman	2a85bef825	Generated code interface for maps is complete, though not yet tested.	5 years ago
Esun Kim	7a1e6aa84b	Support MSVC prior to 2015	5 years ago
Joshua Haberman	cf35baa1ad	Moved macros from upb.h to port_def.inc to avoid leaking them to users. (#160 ) * Use port_def.inc to prevent macros from leaking to users. * Added helpful comments to port_def.inc/port_undef.inc.	6 years ago
Joshua Haberman	33d1231ead	Added port_def.inc and port_undef.inc.	6 years ago
