Andreas Kling	d203a86900	LibJS: Always inline the bytecode instruction iterator's operator++	2021-10-25 13:37:02 +02:00
Ali Mohammad Pur	1414c7b049	LibJS: Add a basic pass manager and add some basic passes ... This commit adds a bunch of passes, the most interesting of which is a pass that merges blocks together, and a pass that places blocks that flow into each other next to each other, and a very simply pass that removes duplicate basic blocks. Note that this does not remove the jump at the end of each block in that pass to avoid scope creep in the passes.	2021-06-15 22:06:33 +04:30
Ali Mohammad Pur	e73b142a97	LibJS: Make basic block size customizable ... And keep the default 4 KiB for the code generator.	2021-06-15 22:06:33 +04:30
Andreas Kling	d560ee118d	LibJS: Allocate 4 KiB for Bytecode::BasicBlock ... There's no reason not to, since we're using mmap() for these anyway and that gives us memory in 4 KiB increments. :^)	2021-06-10 21:59:49 +02:00
Gunnar Beutner	6a0d1fa259	LibJS: Store strings in a string table ... Instead of using Strings in the bytecode ops this adds a global string table to the Executable struct which individual operations can refer to using indices. This brings bytecode ops one step closer to being pointer free.	2021-06-09 17:42:52 +02:00
Ali Mohammad Pur	01e8f0889a	LibJS: Generate bytecode in basic blocks instead of one big block ... This limits the size of each block (currently set to 1K), and gets us closer to a canonical, more easily analysable bytecode format. As a result of this, "Labels" are now simply entries to basic blocks. Since there is no more 'conditional' jump (as all jumps are always taken), JumpIf{True,False} are unified to JumpConditional, and JumpIfNullish is renamed to JumpNullish. Also fixes #7914 as a result of reimplementing the loop logic.	2021-06-09 09:07:29 +02:00
