* | First implementation for 'const' variables | Roberto Ierusalimschy | 2019-05-17 | 1 | -15/+21 |
| | | | | | A variable can be declared const, which means it cannot be assigned to, with the syntax 'local <const> name = exp'. | ||||
* | Keep correct type for immediate operands in comparisons | Roberto Ierusalimschy | 2019-03-22 | 1 | -19/+23 |
| | | | | | | | | | | | | When calling metamethods for things like 'a < 3.0', which generates the opcode OP_LTI, the C register tells that the operand was converted to an integer, so that it can be corrected to float when calling a metamethod. This commit also includes some other stuff: - file 'onelua.c' added to the project - opcode OP_PREPVARARG renamed to OP_VARARGPREP - comparison opcodes rewritten through macros | ||||
* | Added opcodes for arithmetic with K operands | Roberto Ierusalimschy | 2018-11-23 | 1 | -53/+73 |
| | | | | | | | | Added opcodes for all seven arithmetic operators with K operands (that is, operands that are numbers in the array of constants of the function). They cover the cases of constant float operands (e.g., 'x + .0.0', 'x^0.5') and large integer operands (e.g., 'x % 10000'). | ||||
* | Big revamp in the implmentation of labels/gotos | Roberto Ierusalimschy | 2018-10-29 | 1 | -34/+0 |
| | | | | | | | | Added restriction that, when a label is created, there cannot be another label with the same name visible. That allows backward goto's to be resolved when they are read. Backward goto's get a close if they jump out of the scope of some variable; labels get a close only if previous goto to it jumps out of the scope of some upvalue. | ||||
* | Towards "to closed" local variables | Roberto Ierusalimschy | 2018-10-08 | 1 | -2/+2 |
| | | | | | | | | | | | | 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. | ||||
* | Fixed bug in line info. when using 'not' operator | Roberto Ierusalimschy | 2018-07-11 | 1 | -23/+53 |
| | | | | | | | | | When creating code for a jump on a 'not' condition, the code generator was removing an instruction (the OP_NOT) without adjusting its corresponding line information. This fix also added tests for this case and extra functionality in the test library to debug line info. structures. | ||||
