|
* isel: fix immediate of flipped sub lemon2025-12-041-0/+1
|
* cpp: implement preprocessor expressions short circuiting behaviour lemon2025-12-031-17/+23
| | | | This only affects whether an error is given for something like `0 && 0/0` (it shouldn't)
* c: allow redeclaration with K&R and non K&R prototypes lemon2025-12-031-2/+10
|
* preprocessor: add #ifndef...#endif include guard optimization lemon2025-12-024-16/+38
|
* test/11-abi lemon2025-12-022-6/+46
|
* c: make tentative definitions work lemon2025-12-025-18/+57
|
* c: narrowing ints of different signedness... lemon2025-12-011-1/+1

* c: edgecase for redeclaration of implicit sized array lemon2025-12-011-1/+1
|
* driver: add -run option like tcc lemon2025-11-302-24/+80
| | | | convenient for quick testing

|
* isel: fix branch arg lemon2025-11-271-0/+2
|
* abi/isel: aggregate args in stack wip lemon2025-11-272-15/+42
|
* regalloc: skip dead phis lemon2025-11-261-1/+4
|
* c/type: make implicit const T* -> T* conversion warning, not error lemon2025-11-263-4/+11
|
* io: diagnostics print source code underline correctly with hard tabs lemon2025-11-261-8/+26
|
* c: more static initializer fixes lemon2025-11-262-7/+9
|
* c: fix elided-braces initializers for nested unions lemon2025-11-261-5/+16
| | | | | | | | For example in ```c struct {int a; union { int b,c; }; int d; } X = {1,2,3}; ``` Fields `a`,`b`,`d` must get initialized to 1,2,3. Not `c`
* use bstdout for -E lemon2025-11-262-7/+7
|
* amd64/emit: I64 consts and fp push/pop lemon2025-11-241-7/+22
|

|
* pp: fix token pasting (hopefully) lemon2025-11-241-27/+15
|

|
* ir: simplify some occurrences of single-argument phis lemon2025-11-242-8/+17
|
* c: fix condexprvalue lemon2025-11-241-54/+42
| | | | | The original implementation was broken when presented with nested short-circuiting logical operators.
* c: remove unused function lemon2025-11-241-8/+0
|
* c: create dummy unreachable block after trap lemon2025-11-242-5/+2
| | | | | | Reverts 9abe27f6712. This simplies expr codegen, otherwise would manually have to check `fn->curblk != NULL` repeatedly. Later passes will easily delete those unreachable blocks
* isel: loadstoreaddr don't fuseaddr as much lemon2025-11-241-3/+5
|
* ir.h: tweak mkintrin() definition to work with tinycc lemon2025-11-241-1/+1
|
* ir: implement cvtu64f. and other bug fixes lemon2025-11-235-12/+50
| | | | | compiler is bootstrapping?! however, stage1 and stage2+ executables aren't bit-identical.. small differences in the codegen.. need to look into that
* implement cvtfXu64 by lowering it in builder lemon2025-11-232-11/+48
| | | | this should probably be in a separate pass?
* c: check actual reachability for non-void func may not return value lemon2025-11-233-2/+28
|
* c: implement compound initializer in static context lemon2025-11-232-3/+18
