2022-08-29Use bindgen for old manual extern declarations ↵Alan Wu
(https://github.com/Shopify/ruby/pull/404) We have a large extern block in cruby.rs leftover from the port. We can use bindgen for it now and reserve the manual declaration for just a handful of vm_insnhelper.c functions. Fixup a few minor discrepencies bindgen found between the C declaration and the manual declaration. Mostly missing `const` on the C side.

2022-08-29Fix code invalidation while OOM and OOM simulation ↵Alan Wu
(https://github.com/Shopify/ruby/pull/395) `YJIT.simulate_oom!` used to leave one byte of space in the code block, so our test didn't expose a problem with asserting that the write position is in bounds in `CodeBlock::set_pos`. We do the following when patching code: 1. save current write position 2. seek to middle of the code block and patch 3. restore old write position The bounds check fails on (3) when the code block is already filled up. Leaving one byte of space also meant that when we write that byte, we need to fill the entire code region with trapping instruction in `VirtualMem`, which made the OOM tests unnecessarily slow. Remove the incorrect bounds check and stop leaving space in the code block when simulating OOM.

2022-08-29Port cfunc lookup, plus simpler cfunc generators. ↵Noah Gibbs
(https://github.com/Shopify/ruby/pull/388) This port does *not* create invalidation regions to ensure minimum invalidatable block sizes, and so it does not port the to_s generator.

2022-08-29Use new assembler to support global invalidation on A64Alan Wu
Previously, we patched in an x64 JMP even on A64, which resulted in invalid machine code. Use the new assembler to generate a jump instead. Add an assert to make sure patches don't step on each other since it's less clear cut on A64, where the size of the jump varies depending on its placement relative to the target. Fixes a lot of tests that use `set_trace_func` in `test_insns.rb`. PR: https://github.com/Shopify/ruby/pull/379

2022-08-29Fix forward_pass usage in arm backend following John's PRMaxime Chevalier-Boisvert
2022-08-29Fix live_ranges idx calculation (https://github.com/Shopify/ruby/pull/353)John Hawthorn
forward_pass adjusts the indexes of our opnds to reflect the new instructions as they are generated in the forward pass. However, we were using the old live_ranges array, for which the new indexes are incorrect. This caused us to previously generate an IR which contained unnecessary trivial load instructions (ex. mov rax, rax), because it was looking at the wrong lifespans. Presumably this could also cause bugs because the lifespan of the incorrectly considered operand idx could be short. We've added an assert which would have failed on the previous trivial case (but not necessarily all cases). Co-authored-by: Matthew Draper <matthew@trebex.net>
