If some stack does not have a minimum available space, the GC defers
calling a finalizer until the next cycle. That avoids errors while
running a finalizer that the programmer cannot control.
Bug: 'luaD_seterrorobj' should not raise errors2025-03-12T19:01:03+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2025-03-12T19:01:03+00:00urn:sha1:25da574fcbb68bf507431a6091ab73ac434c9428
This function can be called unprotected, so it should not raise any
kind of errors. (It could raise a memory-allocation error when creating
a message).
Several functions turned 'static'2023-05-22T17:47:54+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2023-05-22T17:47:54+00:00urn:sha1:9be74ccc214eb6f4d9d0b9496fd973542c7377d9
Several functions that were already being used only inside their
own file have been declared as 'static'.
Stack indices changed to union's2022-10-29T15:06:37+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2022-10-29T15:06:37+00:00urn:sha1:413a393e6222482f46599e138bebac162610a572
That will allow to change pointers to offsets while reallocating
the stack.

'luaD_pretailcall' mimics 'luaD_precall', handling call metamethods
and calling C functions directly. That makes the code in the
interpreter loop simpler.
This commit also goes back to emulating the tail call in 'luaD_precall'
with a goto, as C compilers may not do proper tail calls and the C
stack can overflow much sooner than the Lua stack (which grows as the
metamethod is added to it).
'luaD_tryfuncTM' checks stack space by itself2021-08-18T15:05:06+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2021-08-18T15:05:06+00:00urn:sha1:91673a8ec0ae55e188a790bd2dfdc99246adf20eUndo simplification of tail calls (commit 901d760)2021-08-18T14:21:33+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2021-08-18T14:21:33+00:00urn:sha1:41871f1803770305f182f56cbd22a336c5236a19
Not that simpler and slower.
Simplification in the parameters of 'luaD_precall'2021-06-30T15:53:21+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2021-06-30T15:53:21+00:00urn:sha1:dbdc74dc5502c2e05e1c1e2ac894943f418c8431
The parameters 'nresults' and 'delta1', in 'luaD_precall', were never
meaningful simultaneously. So, they were combined in a single parameter
'retdel'.
