Andreas Kling	7971cfdd89	LibJS/Bytecode: Move bytecode operand rewriting to a separate pass ... This way we don't have to do it whenever performing some kind of instruction rewrite.	2024-06-02 16:34:08 +02:00
Andreas Kling	7654da3851	LibJS/Bytecode: Do basic compare-and-jump peephole optimization ... We now fuse sequences like [LessThan, JumpIf] to JumpLessThan. This is only allowed for temporaries (i.e VM registers) with no other references to them.	2024-05-10 15:03:24 +00:00
Andreas Kling	cea59b6642	LibJS/Bytecode: Reuse bytecode registers ... This patch adds a register freelist to Bytecode::Generator and switches all operands inside the generator to a new ScopedOperand type that is ref-counted and automatically frees the register when nothing uses it. This dramatically reduces the size of bytecode executable register windows, which were often in the several thousands of registers for large functions. Most functions now use less than 100 registers.	2024-05-09 09:12:13 +02:00
