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 6905d36d73 [cff] Fix fetch_op() bounds-checking 2022-11-21 10:51:33 -07:00
Behdad Esfahbod b51ab1a9e5 [cff] Optimize byte_str_ref_t 
Make it 16 bytes instead of 24.  This struct is used in the subroutine
call stack heavily.

This change makes the HB AdobeVFPrototype benchmark to become faster
than FT one, with about 6% speedup as a result of this change.

Benchmark on AdobeVFPrototype shows 35% speedup. Now we're faster
than FreeType:

Garret Rieger b14475d2ae [subset] further changes to serializer error handling. 
- Rename enum type and enum members.
- in_errors() now returns true for any error having been set. hb-subset now looks for offset overflow only errors to divert to repacker.
- Added INT_OVERFLOW and ARRAY_OVERFLOW enum values.
 2021-03-18 10:51:26 -07:00
Garret Rieger 73ed59f7a6 [subset] store errors in the serializer as a flag set. 
Make check_assign/check_equal specify the type of error to set.

Behdad Esfahbod fa333e34d6 [vector] Remove static_array 
Was good idea, but with C++ types with constructor/destructor, was getting in
the way as compiler was destructing those items where it was not desired.
Since C++ does not allow zero-sized arrays, just remove it...

* test2

* undo tests

* fix bot failure

* undo the previous change

* fixed tabs, added inline

* Revert "fixed tabs, added inline"
