| * | avoid GOT relocations in unnecessary instances | 2025-12-25 | 1 | -2/+7 | |
| | | | | | | Also change xcon to have a flagset for symbols (whether it's a function, locally defined; later: thread local, etc). | ||||
| * | ir: arena-backed linked list for uselists | 2025-12-24 | 1 | -2/+1 | |
| | | | | | | Is much simpler than the growable buffers, seems to be just as efficient if not a little faster when benchmarked. | ||||
| * | lower alloca as a separate pass before isel | 2025-12-23 | 1 | -0/+4 | |
| | | |||||
| * | ir: use BIT macro for regset (1<< is wrong for u64) | 2025-12-23 | 1 | -0/+2 | |
| | | |||||
| * | some static assertions for packed type sizes | 2025-12-20 | 1 | -0/+2 | |
| | | |||||
| * | backend: unify pass memory allocation strategies | 2025-12-20 | 1 | -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. | ||||
| * | backend: general simplification pass skeleton | 2025-12-20 | 1 | -0/+4 | |

| * | ir: move some filluses() to ir.c, rename optmem.c -> mem2reg.c | 2025-12-19 | 1 | -2/+2 | |
| | | |||||
| * | ir: move cls2load to interface | 2025-12-18 | 1 | -0/+1 | |
| | | | | | | There's plenty of code duplication like this around I'm looking to reduce. | ||||
| * | create distinct interned string type | 2025-12-15 | 1 | -6/+6 | |
| | | | | | | | | | | | | | | | Interned strings are used pervasively, so it's a good idea to add a layer of type safety to differentiate them from general cstrs and avoid potential bugs from comparing non-interned and interned strings. Not that that's happened so far that I can remember, but it could. I'm 90% sure it's legal to alias `struct {char c;}` pointers with `char` pointers. This specific typedef gives type safety but with a simple one-way `internstr -> const char *` typecast (with `&istr->c`). Converting the other way around is more intentional: a straight up cast `(internstr)cstr` which sticks out as unchecked and probably wrong, or calling the intern(cstr) function, which is the right way. | ||||
| * | fix position independent loads of function symbols. | 2025-12-13 | 1 | -2/+2 | |
| | | | | | | | | | For `extern int x[1];`, can use PCREL32 for &x. But for `extern int x(int)`, must use GOTREL, when not being called directly (that's PLT). Therefore the type of an external symbol (actually just whether it denotes a function) matters when deciding what kind of relocation to emit, so keep that information. | ||||
| * | ir: bump MAXINSTR | 2025-12-10 | 1 | -1/+1 | |
| | | |||||
| * | abi: fix aggregate passed by regs 2nd reg offset | 2025-12-06 | 1 | -3/+6 | |
| | | | | | | | | | | It was broken for example `struct { i32 a; f64 b; }` (would try to load/store b from byte offset 4, not 8). Introduce r2off, realize in x86-64 it's always 8; even `struct {i32 a; f32 b;}` gets passed in one (integer) register. But not so in (future) ABIs like RISC-V, I believe there `{i32, f32}` would get passed in 1 integer and 1 float register (r2off = 4). | ||||
