* ir: make address ref hash table resizablelemon2026-02-287-27/+49
| | | | Would hit the limit on very large functions (thanks csmith).

|
* regalloc: fix defn of spilled var with immediatelemon2026-02-282-2/+16
| | | | | | With `i64 %a = copy 0xabcdef12345`, if `%a` was spilled, this would turn into a `storei64` instruction with an unencondable immediate operand (larger than 32 bits in x86, non-zero in aarch64).

|
* preprocessor: use shared static buffers for replacement listslemon2026-02-251-150/+178
| | | | | | | One for macro definitions' bodies, another one for function-like macros with substituted arguments in the macro expansion stack. Cuts down on a lot of individual allocations. #undef'd macros' replacement lists are "leaked" but that is very minor
* fix io fa8c39d6df : make buffer shared (for nested note())lemon2026-02-241-1/+1
|
* fix various warningslemon2026-02-246-14/+11
|
* inline: fix undefined value returnslemon2026-02-241-1/+2
| | | | | | Previously if an inlined function has a return statement with no value (control flow reaching the closing brace of the function), would use an invalid null reference in the inlined body. Turn it into undef.
* io: use distinct output buffer for diagnosticslemon2026-02-241-14/+24
| | | | | Prevents concurrent invokations of the compiler from mixing up and mangling diagnostics from unbuffered stderr.
* diagnostics: also print #include provenance for warningslemon2026-02-243-4/+10

* IR: just use an array for extended constantslemon2026-02-199-66/+54

* cfg: dominator computation should ignore blocks with no predecessorslemon2026-02-191-1/+1
| | | | | | | These didn't show up atp before but with inlining, for example, a noreturn function, they could be introduced. And the pass ordering means they wouldn't have been cleaned up before filldom(). An unreachable block having no dominator makes sense too.
