Re: [Tinycc-devel] Preprocessor performance tuning

[Vladimir Vissoultchev]

Probably on this large input some allocators get exhausted and fall back to
standard malloc/free.

In current patch I've increased `TokenString` allocator capacity to 2MB
(increasing total preallocations to 4.25MB) and implemented
TAL_DEBUG/TAL_INFO conditionals for debugging mem leaks and collecting stats
on the allocators incl. count of over capacity allocations (in `nb_failed`
member).

With latest tweaks I get ~58MB/s compilation speed on average, up from
46MB/s by latest mob before the patch.

IMO this is ready to be pushed to mob, unless someone finds something
troubling with the modifications proposed.

cheers,

tcc speed up on one big source (one tcc call with all files) is not
improved: 4%. But speed up on many tcc calls with one file: yes, 7-15%. Nice
result.
