Dump uses varints also for integer constants

2025-06-13T17:14:50+00:00

Unlike sizes, these constants can be negative, so it encodes those integers into unsigned integers in a way that keeps small numbers small.

Variable attributes can prefix name list

2025-05-18T14:43:43+00:00

In this format, the attribute applies to all names in the list; e.g. "global print, require, math".

Collective declaration for globals ('global *')

2025-05-13T14:43:10+00:00

Removed copyright notice from 'testes/all.lua'

2025-03-12T17:00:58+00:00

All test files refer to the main copyright notice in 'lua.h'.

Another way to compile goto's

2025-01-10T16:54:51+00:00

The compilation of a goto or a label just create an entry and generate boilerplate code for the gotos. As we don't know yet whether it needs a CLOSE, we code a jump followed by a CLOSE, which is then dead code. When a block ends (and then we know for sure whether there are variables that need to be closed), we check the goto's against the labels of that block. When closing a goto against a label, if it needs a CLOSE, the compiler swaps the order of the jump and the CLOSE, making the CLOSE active.

Flexible limit for use of registers by constructors

2024-06-27T14:24:27+00:00

Instead of a fixed limit of 50 registers (which, in a bad worst case, can limit the nesting of constructors to 5 levels), the compiler computes an individual limit for each constructor based on how many registers are available when it runs. This limit then controls the frequency of SETLIST instructions.

Clearer code for controlling maximum registers

2024-06-26T17:46:44+00:00

Plus, added a test to check that limit.

Avoid excessive name pollution in test files

2022-12-28T21:34:11+00:00

Test files are more polite regarding the use of globals when locals would do, and when globals are necessary deleting them after use.

Changes in cache for function constants

2021-03-30T17:49:18+00:00

In 'lcode.c', when adding constants to the list of constants of a function, integers represent themselves in the cache and floats with integral values get a small delta to avoid collision with integers. (This change avoids creating artificial addresses; the old implementation converted integers to pointers to index the cache.)

Details (do not affect regular code)

2020-12-07T14:17:30+00:00

* Avoids multiple definitions of 'lua_assert' in test file. * Smaller C-stack limit in test mode. * Note in the manual about the use of false * Extra test for constant reuse.
