New conceptual model for vararg 2025-11-26T14:18:29+00:00 Roberto I roberto@inf.puc-rio.br 2025-11-26T14:18:29+00:00 urn: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. External strings are as good as internal ones 2025-11-11T17:40:30+00:00 Roberto I roberto@inf.puc-rio.br 2025-11-11T17:40:30+00:00 urn:sha1:5b7d9987642f72d44223a8e5e79e013bb2b3d579 A '__mode' metafield and an "n" key both can be external strings. Optimization for vararg tables 2025-09-24T21:33:08+00:00 Roberto I roberto@inf.puc-rio.br 2025-09-24T21:33:08+00:00 urn: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 variable 2025-09-17T19:07:48+00:00 Roberto I roberto@inf.puc-rio.br 2025-09-17T19:07:48+00:00 urn:sha1:8fb1af0e33cd8688f57cd0e3ab86420a8cfe99bd To allow some optimizations on its use.
