Conditionally build `wasm-component-ld` #127866

alexcrichton · 2024-07-17T14:48:16Z

This commit updates the support for the wasm-component-ld tool from #126967 to conditionally build rather than unconditionally building it when LLD is enabled. This support is disabled by default and can be enabled by one of two means:

the extended field in config.toml which dist builders use to build a complete set of tools for each host platform.
a "wasm-component-ld" entry in the tools section of config.toml.

Neither of these are enabled by default meaning that most local builds will likely not have this new tool built. Dist builders should still, however, build the tool.

Sure thing, added. I figured this was a pretty niche and small change and it looks like all users get warnings/prints/etc when updating existing checkouts so I didn't want to spam messages, but if it's desired to have an exhaustive changelog I'm happy to add the entry.

Thanks, no worries about the spam; records are printed only once (unless the build directory is removed).

Hmm the condition to build wasm-component-ld seems inconsistent with other tools (cargo etc.). Those tools require both extended=true and tools containing the name to be built, but here wasm-component-ld requires either extended=true or tools containing its name.

IMO we should change it to match other tools (or there's just no way to build another tool without building wasm-component-ld).

It was [pointed out recently][comment] that enabling `wasm-component-ld` as a host tool is different from other host tools. This commit refactors the logic to match by deduplicating selection of when to build other tools and then using the same logic for `wasm-component-ld`. [comment]: rust-lang#127866 (comment)
