Behdad Esfahbod 59c45f6deb Use hb_memcpy instead of memcpy consistently 2022-11-22 12:54:50 -07:00
Behdad Esfahbod c53c648127 [subset-cff] Another handrolled memcpy 2022-11-22 12:46:25 -07:00
Behdad Esfahbod 1572ba281a [subset-cff] Return in subr closure if already seen subr 
Not sure why this was not done before.

Behdad Esfahbod a29ca6efbc [subset-cff] Comment 2022-11-21 22:02:17 -07:00
Behdad Esfahbod 28e767ddea [subset-cff] Really optimize op_str_t / parsed_cs_op_t layout 
Now parsed_cs_op_t and op_str_t are both 16 bytes.

Saves another 7% in SourceHanSans/10000 benchmark.

Behdad Esfahbod 2d5ee23731 [subset-cff] Readjust parsed_cs_op_t 
Now it doesn't matter anymore since op_str_t is adjusted and
is 16 bytes with 8byte alignment.

Behdad Esfahbod dc3bb5e0ed [subset-cff] Pre-allocate values array for subroutines as well 2022-11-21 18:18:48 -07:00
Behdad Esfahbod c6279224db [cff] Adjust pre-allocation 
This better matches actual usage, given that ops are one or two
bytes, and vector also allocates 50% extra.

Behdad Esfahbod 191025cc96 [cff] Adjust buffer pre-allocation 
Most ops take one or two bytes, so allocate count*2, not count*3.
Shows minor speedup in subsetting benchmark (around 2%).
