#undef UPB_SIZE
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.

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.

#undef UPB_ALIGN_UP
#undef UPB_ALIGN_DOWN
#undef UPB_ALIGN_MALLOC
#undef UPB_ALIGN_OF
Changed upb's arena alignment from 16 to 8. upb has traditionally returned 16-byte-aligned pointers from arena allocation. This was out of an abundance of caution, since users could theoretically be using upb arenas to allocate memory that is then used for SSE/AVX values (eg. [`__m128`](https://docs.microsoft.com/en-us/cpp/cpp/m128?view=msvc-170), which require 16-byte alignment. In practice, the protobuf C++ arena has used 8-byte alignment for 8 years with no significant problems I know of arising from SSE etc. Reducing the alignment requirement to 8 will save memory. It will also help with compatibility on 32-bit architectures where `malloc()` only returns 8-byte aligned memory. The immediate motivation is to fix the win32 build for Python protobuf.
