|
* c: fix use after free lemon2026-01-091-1/+2
| | | | | A silly one, declsbuf.p can be realloc'd in the call to putdecl, but in this statement that pointer could be fetched before the call.
* cpp: fix pasting ident+keyword lemon2026-01-091-4/+7
|
* lexer: multibyte escape seqs in wide character literal lemon2026-01-091-4/+13
| | | | (hacky)

|
* backend: separate instrs for integer/float store lemon2025-12-311-5/+5
|
* c: SYM expr should store decl ref as an index, not pointer lemon2025-12-303-52/+59
| | | | | | | | Because envdecls (now declsbuf) can be resized and invalidate those pointers. I missed this because the default initialization size of that buffer (and the fact that it would mostly only manifest with function-local expressions) made it not really come up in practice. Silly
* cpp: nicer handling of predefined macros lemon2025-12-291-40/+29
|
* backend: start implementing aarch64 lemon2025-12-281-0/+4
|
* avoid GOT relocations in unnecessary instances lemon2025-12-251-1/+1
| | | | | Also change xcon to have a flagset for symbols (whether it's a function, locally defined; later: thread local, etc).
* c: add _Generic lemon2025-12-221-0/+53
|
* c: recognize __attribute__ as decltok, improve diagnostic for expected ↵ lemon2025-12-221-1/+2
| | | | declaration
* preprocessor make some errors just warnings lemon2025-12-221-4/+6
|
* c/c.c: cleanup exprparse a little lemon2025-12-221-13/+12
|
* c: Fix some dumb uses of initialized stuff lemon2025-12-222-10/+12
| | | | | | Can't figure out what's wrong with the change to struct expr from 9721d6ba40 but it makes valgrind complain and causes miscompilation of the compiler itself..
* c: keyword aliases lemon2025-12-213-66/+81
| | | | | Some linux headers use __signed__ for whatever reason.. this is a general fix for those alternate keyword
* c: allow `return voidfn()` extension lemon2025-12-211-4/+30
|
* lexer: more small optimizations lemon2025-12-211-14/+33
|
* lexer: note source of #include when error occurs in #included file lemon2025-12-202-1/+8
|
* c: small typechecking bugfixes lemon2025-12-201-3/+3
|
* some static assertions for packed type sizes lemon2025-12-201-6/+8
|
* backend: unify pass memory allocation strategies lemon2025-12-201-1/+1
| | | | | | It was all over the place for temporary data structures used by individual passes. Now there is an arena specifically for that, which is nicer.
* c: support CRLF newlines lemon2025-12-201-3/+11
|
* c: fix a silly C edge case with function redeclaration storage class lemon2025-12-201-14/+21
| | | | | | C (or at least clang and gcc) allows declaring `static int f(...);` and defining it later as `int f(...) {...}`, omitting the 'static' in the latter definition.
* lexer: fix remnant use of TKEOF for character lemon2025-12-201-9/+7
|
* optimize lexer a bit more lemon2025-12-202-62/+88
|

|
* c: factor out to tldecl(), improve error recovery, lemon2025-12-201-73/+97
|
* c.h init zero bitset portability lemon2025-12-191-1/+1
|
* c: support 0-length arrays as syntax for flexible array members lemon2025-12-191-19/+29
| | | | | Keeping the expr around in the decllist paves the way for VLA support later on
* c: fix incr/decr codegen for floats lemon2025-12-191-2/+2
