* Added gcc option '-Wconversion'Roberto Ierusalimschy2024-07-271-9/+9
| | | | | No warnings for standard numerical types. Still pending alternative numerical types.
* Cleaning of llimits.hRoberto Ierusalimschy2024-06-201-0/+1
| | | | | | Several definitions that don't need to be "global" (that is, that concerns only specific parts of the code) moved out of llimits.h, to more appropriate places.
* 'luaH_get' functions return tag of the resultRoberto Ierusalimschy2024-03-211-2/+3
| | | | | | | Undoing previous commit. Returning TValue increases code size without any visible gains. Returning the tag is a little simpler than returning a special code (HOK/HNOTFOUND) and the tag is useful by itself in some cases.
* 'luaH_get' functions return 'TValue'Roberto Ierusalimschy2024-03-181-2/+2
| | | | | | Instead of receiving a parameter telling them where to put the result of the query, these functions return the TValue directly. (That is, they return a structure.)
* Removed type 'varint_t'Roberto Ierusalimschy2024-03-131-9/+13
| | | | | | size_t should be big enough to count the number of strings in a dump. (And, by definition, it is big enough to count the length of each string.)
* Revising code for Varint encoding in dumpsRoberto Ierusalimschy2024-02-121-17/+18
| | | | | | | | - Usign lua_Unsigned to count strings. - Varint uses a type large enough both for size_t and lua_Unsigned. - Most-Significant Bit 0 means last byte, to conform to common usage. - (unrelated) Change in macro 'getaddr' so that multiplication is by constants.
* Fixed buffers reuse absolute line informationRoberto Ierusalimschy2023-12-271-3/+4
|
* Cleaner protocol between 'lua_dump' and writer functionRoberto Ierusalimschy2023-12-141-7/+23
| | | | | 'lua_dump' signals to the writer function the end of a dump, so that is has more freedom when using the stack.
* Correct anchoring and GC barriers in 'loadString'Roberto Ierusalimschy2023-11-131-5/+2
| | | | | | Call to 'luaH_setint' could call the GC with the string unanchored. Moreover, previously saved strings were being assigned to the prototype without a barrier.
* Fixed buffers save long strings as external.Roberto Ierusalimschy2023-11-101-1/+1
|
* Solving merge issue with use of tables in dump/undumpRoberto Ierusalimschy2023-11-081-4/+4
| | | | | | The use of tables in dump/undump to reuse strings did not exist in the version that changed the representation of arrays, so it was not corrected for the new API for tables.
* New macro 'getlstr'Roberto Ierusalimschy2023-08-301-7/+8
| | | | Accesses content and length of a 'TString'.
* Field 'Proto.is_vararg' uses only one bitRoberto Ierusalimschy2023-08-301-1/+1
| | | | So that the other bits can be used for other purposes.
* Opcode in dumps is stored properly alignedRoberto Ierusalimschy2023-08-251-0/+14
|
* Merge branch 'master' into nextversionRoberto Ierusalimschy2023-06-221-2/+6

| * Bug: Loading a corrupted binary file can segfaultRoberto Ierusalimschy2023-03-171-2/+6
| | | | | | | | | | The size of the list of upvalue names are stored separated from the size of the list of upvalues, but they share the same array.
* | Dump doesn't need to reuse 'source'Roberto Ierusalimschy2022-12-201-6/+6
| | | | | | | | All strings are being reused now, including 'source'.
* | Dump/undump reuse stringsRoberto Ierusalimschy2022-12-151-6/+31
|/ | | | | A repeated string in a dump is represented as an index to its first occurence, instead of another copy of the string.
* Back to old encoding of versions in binary filesRoberto Ierusalimschy2020-05-061-1/+1
| | | | | | (Undoing part of commit f53eabeed8.) It is better to keep this encoding stable, so that all Lua versions can read at least the version of a binary file.
* Code style in 'ldump'/'lundump'.Roberto Ierusalimschy2020-02-271-76/+76
| | | | | - function names start with lower case; - state is always the first parameter.
* Clearer distinction between types and tagsRoberto Ierusalimschy2020-01-311-9/+9
| | | | | LUA_T* represents only types; tags (types + Variants) are represented by LUA_V* constants.
* Changed internal representation of booleansRoberto Ierusalimschy2020-01-061-4/+1
| | | | | | | Instead of an explicit value (field 'b'), true and false use different tag variants. This avoids reading an extra field and results in more direct code. (Most code that uses booleans needs to distinguish between true and false anyway.)
* First implementation of constant propagationRoberto Ierusalimschy2019-07-121-1/+1
| | | | | Local constant variables initialized with compile-time constants are optimized away from the code.
* New implementation for constantsRoberto Ierusalimschy2019-07-091-0/+1
| | | | | | | | | VLOCAL expressions keep a reference to their corresponding 'Vardesc', and 'Upvaldesc' (for upvalues) has a field 'ro' (read-only). So, it is easier to check whether a variable is read-only. The decoupling in VLOCAL between 'vidx' ('Vardesc' index) and 'sidx' (stack index) should also help the forthcoming implementation of compile-time constant propagation.
* Small changes in the header of binary filesRoberto Ierusalimschy2019-03-191-3/+1
| | | | | | | | | - LUAC_VERSION is equal to LUA_VERSION_NUM, and it is stored as an int. - 'sizeof(int)' and 'sizeof(size_t)' removed from the header, as the binary format does not depend on these sizes. (It uses its own serialization for unsigned integer values.)
* 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.
* better names for macros for tags and types.Roberto Ierusalimschy2018-02-261-3/+3
| | | | | rttype -> rawtt; ttyperaw -> withvariant; ttype -> ttypetag; tnov -> ttype
* detail (identation of switch)Roberto Ierusalimschy2017-11-281-18/+17
|
* dumping ints and size_ts compactedRoberto Ierusalimschy2017-06-271-11/+21
|
* 'lineinfo' in prototypes saved as differences instead of absoluteRoberto Ierusalimschy2017-06-271-1/+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.)
* avoid calling write function with empty blockRoberto Ierusalimschy2015-10-081-2/+2
|
* avoid expression with side effect (in debug mode) inside 'sizeof'Roberto Ierusalimschy2015-03-301-2/+3

* size of short strings stored in a single byte, to reduce the sizeRoberto Ierusalimschy2015-01-161-2/+2
| | | | of struct 'TString'
* added include for 'lprefix.h', for stuff that must be added beforeRoberto Ierusalimschy2014-11-021-3/+6
| | | | any other header file
* type 'TString' refers directly to the structure inside the unionRoberto Ierusalimschy2014-07-181-3/+3
| | | | (union used only for size purposes)
* allows different 'source' for each prototype, but inherits it fromRoberto Ierusalimschy2014-06-181-10/+17
| | | | | parent when they are equal (only possible case for chunks created by the parser)
* added assertion about sources being the same for all protos in a chunkRoberto Ierusalimschy2014-06-181-2/+4
|

* make all dumps/loads go trhough Load/DumpVector (so it is easierRoberto Ierusalimschy2014-03-111-4/+10

* keep chunk's headers compatible at least up to LUAC_VERSION (to beRoberto Ierusalimschy2014-03-111-3/+5

* "indent -kr -i2 -br -brf -nut" plus a few manual formatingRoberto Ierusalimschy2014-03-101-137/+141

* no need to store a full 'size_t' fo the size of (frequent) small stringsRoberto Ierusalimschy2014-03-011-11/+11
