This adds a whole bunch of tests checking for any difference with llvm's
archive writer. It also fixes two mistakes in the porting from C++ to
Rust. The first one causes a divergence for Mach-O archives which may or
may not be harmless. The second will definitively cause issues, but only
applies to thin archives, which rustc currently doesn't create.
FIX - StrippingDebugInfoFailed typo
DELETE - unneeded FIXME comment
UPDATE - only declare the error with ExtractBundledLibsError as an enum and use the Diagnostic derive macro
This avoids monomorphizing all linker code for each codegen backend and
will allow passing in extra information to the archive builder from the
codegen backend.
This does not yet support #[link_name] attributes on functions, the #[link_ordinal]
attribute, #[link(kind = "raw-dylib")] on extern blocks in bin crates, or
stdcall functions on 32-bit x86.
This commit implements both the native linking modifiers infrastructure
as well as an initial attempt at the individual modifiers from the RFC.
It also introduces a feature flag for the general syntax along with
individual feature flags for each modifier.
with an eye on merging `TargetOptions` into `Target`.
`TargetOptions` as a separate structure is mostly an implementation detail of `Target` construction, all its fields logically belong to `Target` and available from `Target` through `Deref` impls.
Preparation for a subsequent change that replaces
rustc_target::config::Config with its wrapped Target.
On its own, this commit breaks the build. I don't like making
build-breaking commits, but in this instance I believe that it
makes review easier, as the "real" changes of this PR can be
seen much more easily.
