when a Run step that captures stderr fails, no output from it is visible
by the user and, since the step failed, any downstream step that would
process the captured stream will not run, making it impossible for the
user to see the stderr output from the failed process invocation, which
makes for a frustrating puzzle when this happens in CI.
Wow, *lots* of backends were reliant on Sema doing the heavy lifting for
them. CBE, Wasm, and SPIR-V have all regressed in places now that they
actually need to, like, initialize unions and such.
Changes fmtId to return the FormatId type directly, and renames the
FormatId.render function to FormatId.format, so it can be used in a
format expression directly.
Why? Since `render` is private, you can't create functions that wrap
`fmtId` or `fmtIdFlags`, since you can't name the return type of those
functions outside of std itself.
The current setup _might_ be intentional? In which case I can live with
it, but I figured I'd make a small contrib to upstream zig :)
This eliminates a footgun and special case handling with fixed buffers,
as well as allowing decompression streams to keep a window in the output
buffer.
Not only are `Step.Compile` methods like `linkLibC()` redundant because
`Module` exposes the same APIs, it also might not be immediately obvious
to users that these methods modify the underlying root module, which can
be a footgun and lead to unintended results if the module is exported to
package consumers or shared by multiple compile steps.
Using `compile.root_module.link_libc = true` makes it more clear to
users which of the compile step and the module owns which options.
besides simply being redundant work, the now removed normalize call would cause
spawn to errantly fail (BadPath) when passing a relative path which traversed
'above' the current working directory. This case is already handled by leaving
normalization to the windows.wToPrefixedFileW call in
windowsCreateProcessPathExt
This passes tests but it doesn't provide as big a window size as is
required to decompress larger streams.
The next commit in this branch will work towards that, without
introducing an additional buffer.
