2018-08-07Set 'PrepareForThinLTO' whenever doing cross-language LTO.Michael Woerister-1/+2
2018-08-07Make sure upstream object files are added to staticlibs when compilingMichael Woerister-1/+5
with ThinLTO and cross-lang-lto. Normally, when compiling with whole-crate-graph ThinLTO, we expect rustc's LTO step to "uplift" upstream object files/LLVM modules to the current set of compilation artifacts. Therefore the staticlib creation code skips this uplifting. However, when compiling with "cross-language LTO" (i.e. defer LTO to the actual linker), the LTO step in rustc is not performed, so we have to take care of copying upstream object files during archive creation (like we already do when compiling without any LTO).
2018-08-07Fix issue around dllimport and ThinLTO as LLD runs it.Michael Woerister-7/+36
2018-08-07Rollup merge of #53028 - Mark-Simulacrum:split-out-codegen, r=alexcrichtonkennytm-27/+0
Building librustc_codegen_llvm in a separate directory This allows clearing it out and building it separately from the compiler. Since it's essentially a different and separate crate this makes sense to do, each cargo invocation should generally happen in its own directory. r? @alexcrichton
2018-08-07Auto merge of #51007 - AstralSorcerer:master, r=nagisabors-14/+60
Make globals with private linkage unnamed. Fixes #50862. cc @oli-obk @nagisa

Reintroduce `Undef` and properly check constant value sizes r? @RalfJung cc @eddyb basically all kinds of silent failures that never occurred are assertions now
2018-08-03Auto merge of #52887 - yurydelendik:disable-lld-symbols, r=alexcrichtonbors-0/+12
Disable debug sections when optimization flags is set for LLD. Currently LLD does not error when optimization is set and debugging information sections are present. (See discussion at https://reviews.llvm.org/D47901) Using `--strip-debug` along with the `-O` option.

2018-08-01Make sure we prepare for thin LTO whenever we are emitting bitcodeColin Pronovost-0/+31
Emitting LLVM bitcode uses ThinLTOBuffers, so we need to prepare for thin LTO or we will likely cause errors in LLVM.

2018-07-31rustc: Handle linker diagnostic from LLVMAlex Crichton-8/+22
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.
