'lua_load' does not preserve the stack through the calls to the
reader function, as it should. Immediately after the first call (to
detect whether chunk is binary) it adds stuff, and it also adds a new
table when starting the compilation of each new function.
Optimization for vararg tables2025-09-24T21:33:08+00:00Roberto Iroberto@inf.puc-rio.br2025-09-24T21:33:08+00:00urn:sha1:25c54fe60e22d05cdfaa48c64372d354efa59547
A vararg table can be virtual. If the vararg table is used only as
a base in indexing expressions, the code does not need to create an
actual table for it. Instead, it compiles the indexing expressions
into direct accesses to the internal vararg data.
Varag parameter is a new kind of variable2025-09-17T19:07:48+00:00Roberto Iroberto@inf.puc-rio.br2025-09-17T19:07:48+00:00urn:sha1:8fb1af0e33cd8688f57cd0e3ab86420a8cfe99bd
To allow some optimizations on its use.

No need to limit variable declarations to 2502025-06-18T19:45:55+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2025-06-18T19:45:55+00:00urn:sha1:07b009c3712c062957593d0a4fa82e0fe9023024
Only local variables, which use registers, need this low limit.
New way to control preambular declaration2025-05-20T20:36:05+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2025-05-20T20:36:05+00:00urn:sha1:be05c444818989463dc307eed283503d391f93eb
Validity of the preambular global declaration in controled together
with all declarations, when checking variable names.
'expdesc' doesn't depend on 'actvar' for var. info.2025-05-11T14:51:58+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2025-05-11T14:51:58+00:00urn:sha1:5b1ab8efdcb7b48cab8148a407266c467d57114c
In preparation for 'global *', the structure 'expdesc' does not point
to 'actvar.arr' for information about global variables.
