| | | | | Treated as unsized array T[]. This shows up in some linux headers as a non-standard way to have flexible array members.

* various relocation related optimizationlemon2025-12-146-56/+78
| | | | | | | | | | With 59ca5a8db, querying if a symbol is defined is cheap. If we're compiling code that calls foo() and we defined foo() in this compilation unit, we already know its offset within the .text section, so use it instead of emitting a relocation for the linker to handle. Also, put small literal data in the .text section instead of .rodata. This seems to improve performance (cache locality?), and as a bonus, it will be good for aarch64's instr encoding with smallish PC-relative offsets.
* elf: use a hashmap for looking up symbolslemon2025-12-142-32/+52
| | | | | Gets rid of linear-time findsym(), though needs some extra indirection to emit sorted symbols.

| | | | | sqlite3 was falling back to `((void*)&((char*)0)[X])` for INT_TO_PTR, which this handles now.

* fix position independent loads of function symbols.lemon2025-12-139-26/+48
| | | | | | | | 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.

| | | | | | Function parameters qualifiers don't matter outside of function definition. `int (const int)` should be compatible with `int(int)` etc. So no need to store them in the typedata.

* regalloc: optimize a little edge case betterlemon2025-12-101-4/+6
| | | | | | | | | | | | With two-address instructions one needs to make sure the dst doesn't get allocated to the same reg as the right-hand operand: %r = mul %x, %y ; %y cannot be %r Except, if the operands are the same %r = mul %x, %x ; if %x is dead after this instr, it's fine to allocate %r to the same reg
