Stack indices changed to union's 2022-10-29T15:06:37+00:00 Roberto Ierusalimschy roberto@inf.puc-rio.br 2022-10-29T15:06:37+00:00 urn:sha1:413a393e6222482f46599e138bebac162610a572 That will allow to change pointers to offsets while reallocating the stack.

'luaL_newstate' should not allocate extra memory 2020-11-03T19:34:36+00:00 Roberto Ierusalimschy roberto@inf.puc-rio.br 2020-11-03T19:34:36+00:00 urn:sha1:58216600eba27d472de33dbb89e2f3e629bf8a59 The allocation of a userdata for the state of the warn system can cause a panic if it fails; 'luaL_ref' also can fail. This commit re-implements the warn system so that it does not need an explicit state. Instead, the system uses different functions to represent the different states.

Simplification and smaller buffers for 'lua_pushfstring' 2020-07-03T14:36:56+00:00 Roberto Ierusalimschy roberto@inf.puc-rio.br 2020-07-03T14:36:56+00:00 urn:sha1:e96385adede47a1abf160a41565ec742d3d4e413 The function 'lua_pushfstring' is seldom called with large strings, there is no need to optimize too much for that cases. Undo change in the handling of 'L->top' (commit b80077b8f3) 2019-08-29T15:52:37+00:00 Roberto Ierusalimschy roberto@inf.puc-rio.br 2019-08-29T15:52:37+00:00 urn:sha1:72a094bda7d71050a91a88474d67d39aa2bc1c46 With MMBIN instructions, there are fewer opcodes that need to update 'L->top', so that change does not seem to pay for the increased complexity.
