2018-08-31Provide a way of accessing the ThinLTO module import map in rustc.Michael Woerister-0/+9
2018-08-28Fix warnings about the `native` target-cpuAlex Crichton-0/+1
This fixes a regression from #53031 where specifying `-C target-cpu=native` is printing a lot of warnings from LLVM about `native` being an unknown CPU. It turns out that `native` is indeed an unknown CPU and we have to perform a mapping to an actual CPU name, but this mapping is only performed in one location rather than all locations we inform LLVM about the target CPU. This commit centralizes the mapping of `native` to LLVM's value of the native CPU, ensuring that all locations we inform LLVM about the `target-cpu` it's never `native`. Closes #53322

Make LLVM emit assembly comments with -Z asm-comments Fixes #35741, and makes `-Z asm-comments` actually do something useful.

2018-08-13Auto merge of #53161 - michaelwoerister:cstrings, r=wesleywiserbors-2/+3
Avoid many allocations for CStrings during codegen. Giving in to my irrational fear of dynamic allocations. Let's see what perf says to this.
2018-08-12Make LLVM emit assembly comments with -Z asm-comments.whitequark-1/+2
Fixes #35741.
2018-08-10[nll] librustc_codegen_llvm: change Child signature to fix error pointed out ↵memoryruins-1/+1
by nll As explained by eddyb in #53221, "An &ArchiveChild doesn't point into the archive itself, it points to an owned object that itself points to the archive, and LLVMRustArchiveMemberNew copies the ArchiveChild (whereas the current signature suggests it keeps the &ArchiveChild)."

2018-07-31rustc: Handle linker diagnostic from LLVMAlex Crichton-0/+5
Previously linker diagnostic were being hidden when two modules were linked together but failed to link. This commit fixes the situation by ensuring that we have a diagnostic handler installed and also adds support for handling linker diagnostics.
