* Stack indices changed to union'sRoberto Ierusalimschy2022-10-291-1/+1
| | | | | That will allow to change pointers to offsets while reallocating the stack.
* Optimization/simplification of 'getbaseline'Roberto Ierusalimschy2021-02-021-2/+2
| | | | | By producing absolute line information at regular intervals, a simple division can compute the correct entry for a given instruction.
* Optimizations for line hookRoberto Ierusalimschy2021-01-281-0/+10
| | | | | The function 'changedline' tries harder to avoid calling 'luaG_getfuncline' plus small changes in the use of 'L->oldpc'.
* Better error messages for calling non-callable objectsRoberto Ierusalimschy2020-12-291-0/+1
| | | | | | | When available, use the calling code to find a suitable name for what was being called; this is particularly useful for errors of non-callable metamethods. This commit also improved the debug information for order metamethods.
* Fixed bug: invalid 'oldpc' when returning to a functionRoberto Ierusalimschy2020-07-171-0/+5
| | | | | | | | | | The field 'L->oldpc' is not always updated when control returns to a function; an invalid value can seg. fault when computing 'changedline'. (One example is an error in a finalizer; control can return to 'luaV_execute' without executing 'luaD_poscall'.) Instead of trying to fix all possible corner cases, it seems safer to be resilient to invalid values for 'oldpc'. Valid but wrong values at most cause an extra call to a line hook.
* A to-be-closed variable must have a closable value (or be nil)Roberto Ierusalimschy2018-11-291-0/+2
| | | | | | | It is an error for a to-be-closed variable to have a non-closable non-nil value when it is being closed. This situation does not seem to be useful and often hints to an error. (Particularly in the C API, it is easy to change a to-be-closed index by mistake.)
* Better error messages for invalid operands in numeric 'for'Roberto Ierusalimschy2018-10-301-0/+2
| | | | | | "Better" and similar to error messages for invalid function arguments. *old message: 'for' limit must be a number *new message: bad 'for' limit (number expected, got table)
* 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.
* added 'const' to 'Proto*' when possibleRoberto Ierusalimschy2018-06-081-2/+2
|
* minimizing the code ran by 'vmfetch' + no more 'vra'Roberto Ierusalimschy2018-05-021-2/+2
| | | | (the code is simpler without 'vra' and conversion is a no-op)
* janitor work on castsRoberto Ierusalimschy2018-01-281-2/+2
|
* 'lineinfo' in prototypes saved as differences instead of absoluteRoberto Ierusalimschy2017-06-271-3/+7
| | | | | | 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.)
