eed7c104 - pulley: Allow disabling SIMD in the interpreter at compile-time (#10727)

Mon, 05 May 2025 20:34:13 +0000

pulley: Allow disabling SIMD in the interpreter at compile-time (#10727)This commit adds a new feature to Pulley which is used to reduce thecompiled code size of the interpreter itself by disabling SIMD opcodeinterpretation at compile-time. The goal here is to be low-impact onPulley itself to avoid needing `#[cfg]` all over the place and toadditionally avoid the need to redesign Pulley's opcode macro for use invarious parts of Wasmtime.Methods are annotated with a custom macro in the interpreter whichregisters a `#[cfg]` that either does the listed implementation orswitches to an implementation that emits a trap if executed. This meansthat it's safe to execute mismatched code where SIMD was enabled atcompile time but disabled at runtime, it just means the semantics may bea bit surprising to debug.Note that this SIMD is still enabled by default, and an explicit `--cfg`via `RUSTFLAGS` is required to compile-out the SIMD support. Cargofeatures aren't a great fit for this sort of feature so an explicit flagis used. List of files: /wasmtime-44.0.1/docs/examples-pulley.md

refactor(docs): more conversions of sh to console for copy-paste (#10707)This commit udpates more instructions on various READMEs to avoid `$`for easy copy-pasting, and also use `console` where appropriate.Signed-off-by: Victor Adossi List of files: /wasmtime-44.0.1/docs/examples-pulley.md

3e406d2e - Add a `wasmtime objdump` subcommand (#10405)

Thu, 20 Mar 2025 19:23:59 +0000

Add a `wasmtime objdump` subcommand (#10405)This commit adds an `objdump` subcommand to the `wasmtime` CLI. Like allother subcommands this can be disabled for a more minimal build of theCLI as well. The purpose of this subcommand is to provide aWasmtime-specific spin on the venerable native `objdump` itself. Notablythis brings Wasmtime-specific knowledge for filtering functions, showingWasmtime metadata, etc.This command is intended to look like `objdump` roughly but also hasconfigurable output with various flags and things that can be printed.For now the main Wasmtime additions are showing the address mapsection, stack map section, and trap section of a `*.cwasm` file.This new subcommand replaces the infrastructure of the `disas` testsuite, and now that test suite uses `wasmtime objdump` to generate testexpectations. Additionally the subcommand replaces the Pulley `objdump`example as a more full-featured objdump that also works natively withPulley.The hope is that if we add more binary metadata in the future (such asunwinding tables) that can be relatively easily added here forexploration as well. Otherwise this is mostly just a developerconvenience for Wasmtime developers as well and hopefully doesn't costtoo much in maintenance burden.Closes #10336 List of files: /wasmtime-44.0.1/docs/examples-pulley.md
