[truetype] Minor code refactoring.
Two benefits: The allocated FDEF (and IDEF) array gets slightly smaller, and the `ttdebug' demo program has access to function numbers without additional costs. Fortunately, no changes to FontForge are necessary – this is the only external TrueType debugger I know of, but others may exist and should check the code accordingly. * src/truetype/ttinterp.h (TT_CallRec): Replace `Cur_Restart' and `Cur_End' with a pointer to the corresponding `TT_DefRecord' structure. * src/truetype/ttinterp.c (DO_JROT, DO_JMPR, DO_JROF, Ins_ENDF, Ins_CALL, Ins_LOOPCALL, Ins_UNKNOWN, TT_RunIns <Invalid_Opcode>): Updated.

[truetype] Minor code refactoring.
|
||||
|
||||
Two benefits: The allocated FDEF (and IDEF) array gets slightly
|
||||
smaller, and the `ttdebug' demo program has access to function
|
||||
numbers without additional costs.
|
||||
|
||||
Fortunately, no changes to FontForge are necessary – this is the
|
||||
only external TrueType debugger I know of, but others may exist and
|
||||
should check the code accordingly.
|
||||
|
||||
* src/truetype/ttinterp.h (TT_CallRec): Replace `Cur_Restart' and
|
||||
`Cur_End' with a pointer to the corresponding `TT_DefRecord'
|
||||
structure.
|
||||
|
||||
* src/truetype/ttinterp.c (DO_JROT, DO_JMPR, DO_JROF, Ins_ENDF,
|
||||
Ins_CALL, Ins_LOOPCALL, Ins_UNKNOWN, TT_RunIns <Invalid_Opcode>):
|
||||
Updated.
