* Towards "to closed" local variablesRoberto Ierusalimschy2018-10-081-4/+30
| | | | | | | | | | | | Start of the implementation of "scoped variables" or "to be closed" variables, local variables whose '__close' (or themselves) are called when they go out of scope. This commit implements the syntax, the opcode, and the creation of the corresponding upvalue, but it still does not call the finalizations when the variable goes out of scope (the most important part). Currently, the syntax is 'local scoped name = exp', but that will probably change.

* Removed extra information from RCS keyword stringsRoberto Ierusalimschy2018-08-231-1/+1
| | | | | Version numbers and dates (mostly wrong) from RCS keyword strings removed from all source files; only the file name are kept.
* in generational mode, an emergency collection can turn any object blackRoberto Ierusalimschy2018-06-181-2/+2
| | | | during any memory allocation.
* no more nil-in-tableRoberto Ierusalimschy2018-04-041-15/+1
|
* new experimental syntax using reserved word 'undef'Roberto Ierusalimschy2018-03-071-11/+18
|
* correct way to check stack space for vararg functionsRoberto Ierusalimschy2018-02-171-3/+1
|
* vararg back to '...' (but with another implementation)Roberto Ierusalimschy2018-02-091-16/+6
| | | | new implementation should have zero overhead for non-vararg functions
* new opcode 'PREPVARARG'Roberto Ierusalimschy2018-02-071-6/+16
| | | | (avoids test for vararg function in all function calls)
* new macros 'isOT'/'isIT'Roberto Ierusalimschy2017-12-221-2/+2
| | | | | (plus exchanged parameters of OP_VARARG to make it similar to other 'isOT' instructions)
* new opcodes 'FORLOOP1'/'FORPREP1' for "basic for" (integer variableRoberto Ierusalimschy2017-12-181-15/+36
| | | | with increment of 1)
* details (cleaning uses of 'exp1')Roberto Ierusalimschy2017-12-181-8/+5
|
* 'Proto->numparams' does not include vararg parameterRoberto Ierusalimschy2017-12-151-5/+4
| | | | (one less subtraction when calling functions...)
* 'VRELOCABLE' -> 'VRELOC'Roberto Ierusalimschy2017-12-141-3/+3
|
* avoid using one function for different tasks (malloc, free, etc.)Roberto Ierusalimschy2017-12-061-16/+9
|
* small peephole optimizationsRoberto Ierusalimschy2017-11-301-2/+2
|
* no more 'stackless' implementation; 'luaV_execute' calls itselfRoberto Ierusalimschy2017-11-231-8/+4
| | | | | recursively to execute function calls. 'unroll' continues all executions suspended by an yield (through a long jump)
* detailRoberto Ierusalimschy2017-10-041-2/+3
|
* no more 'getBMode'-'getCMode' (imprecise + we will need more spaceRoberto Ierusalimschy2017-09-281-2/+2
| | | | for op mode) + better control of op modes
* jumps do not close upvalues (to be faster and simpler);Roberto Ierusalimschy2017-09-131-46/+81
| | | | | | explicit instruction to close upvalues; command 'break' not handled like a 'goto' (to optimize removal of uneeded 'close' instructions)

* 'lineinfo' in prototypes saved as differences instead of absoluteRoberto Ierusalimschy2017-06-271-4/+9
| | | | | | values, so that the array can use bytes instead of ints, reducing its size. (A new array 'abslineinfo' is used when line differences do not fit in a byte.)

* do not eliminate varargs from functions that do not use varargsRoberto Ierusalimschy2016-08-011-4/+3

* bug: expression list with four or more expressions inRoberto Ierusalimschy2016-06-221-5/+4
| | | | | a 'for' loop can crash the interpreter. ('adjust_assign' must remove extra expresssions from its registers.)
