From b9b7f048b0874df0f034f6b1e15e1a4ee2131475 Mon Sep 17 00:00:00 2001 From: _ov4 Date: Sun, 26 Jul 2026 12:12:59 +0000 Subject: refactor: centralize libc declarations, move '&' concat into StringHandler CodeGen declares its own MallocFunc in SetupExternalFunctions and uses it for char->STRING coercion and INPUT STRING buffers, removing two bare getFunction("malloc") calls that null-deref'd if no handler happened to declare malloc first. The CHR branch reuses the char->STRING coercion path instead of a second hand-rolled heap wrapper. String concatenation moves from ArithmeticHandler (which re-declared four externs per '&' and was the LLVM 19 build-pin root cause) to StringHandler::emitConcat; ArithmeticHandler no longer touches the Module. Dead FreeFunc declarations removed.
