Vararg functions with vararg tables don't use the arguments hidden in
the stack; therfore, it doesn't need to build/keep them.
New conceptual model for vararg2025-11-26T14:18:29+00:00Roberto Iroberto@inf.puc-rio.br2025-11-26T14:18:29+00:00urn:sha1:f33cc4ddec886ea499d7d41dd60cac5ddc5687db
Conceptually, all functions get their vararg arguments in a vararg
table. The storing of vararg arguments in the stack is always treated
as an optimization.
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.
Vararg table2025-09-16T16:26:24+00:00Roberto Iroberto@inf.puc-rio.br2025-09-16T16:26:24+00:00urn:sha1:140b672e2ee2ac842661ece4b48e1a64f0cd11ea
Not yet optimized nor documented.
Short strings can be external, too2025-07-15T17:40:27+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2025-07-15T17:40:27+00:00urn:sha1:60b6599e8322dd93e3b33c9496ff035a1c45552f
That complicates a little object equality (and therefore table access
for long strings), but the old behavior was somewhat weird. (Short
strings, a concept otherwise absent from the manual, could not be
external.)
Using 'l_uint32' for unicode codepoints in scanner2025-05-08T15:49:39+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2025-05-08T15:49:39+00:00urn:sha1:d827e96f33056bcc0daca0c04b3273604f9d5986
'l_uint32' is enough for unicode codepoints (versus unsigned long),
and the utf-8 library already uses that type.
New macro 'pushvfstring'2025-04-23T14:55:04+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2025-04-23T14:55:04+00:00urn:sha1:e05590591410a5e007a1e3f1691f6c1cf9d8fe45
Helps to ensure that 'luaO_pushvfstring' is being called correctly,
with an error check after closing the vararg list with 'va_end'.
Refactoring of 'luaH_newkey'2024-12-05T17:27:58+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2024-12-05T17:27:58+00:00urn:sha1:bb93f04d87cfc093757dc712905e1fe3fbe65f58
Function broke in two and some checks moved to the caller. (We may
want to call it without the checks.)
New way to keep hints for table length2024-11-29T20:26:20+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2024-11-29T20:26:20+00:00urn:sha1:002beeebe79065e03dd9f531bee367e8459e3f64
Instead of using 'alimit' for keeping the size of the array and at
the same time being a hint for '#t', a table now keeps these two
values separate. The Table structure has a field 'asize' with the
size of the array, while the length hint is kept in the array itself.
That way, tables with no array part waste no space with that field.
Moreover, the space for the hint may have zero cost for small arrays,
if the array of tags plus the hint still fits in a single word.
