452086fb - Store stack maps in an ELF section (#10404)

Thu, 20 Mar 2025 19:46:14 +0000

Store stack maps in an ELF section (#10404)* Store stack maps in an ELF sectionThis commit moves the storage of stack maps from being embedded withinserde-encoded information to instead being stored in a separate ELFsection in the final executable. The motivation for this is to make thismore easily debuggable with a `wasmtime objdump` command in the futurebut this additionally should have the nice side effect of makingnon-stack-maps modules have smaller encoded information (no need toencode an empty list) and additionally make stack-maps-using-modulesfaster to decode (no serde decoding, it's already "decoded").This implements a scheme similar to the address map section wherethere's a "builder" for the section and then a separate half to decodethe section. The same basic encoding, a bit map, is used. This is likelygoing to make accessing stack maps slightly slower, but if that's anissue we can tweak the representation and align things and/or use`usize` or such.* Update crates/environ/src/compile/stack_maps.rsCo-authored-by: Andrew Brown * Review comments* More review comments* Fix MIRI test by enabling `unaligned` object feature---------Co-authored-by: Andrew Brown List of files: /wasmtime-44.0.1/crates/environ/src/compile/stack_maps.rs
