Implements part of #49879:

  • Adds a -Z cross-lang-lto flag to rustc
  • Makes sure that bitcode is embedded in object files if the flag is set.

This should already allow for using cross language LTO for staticlibs (where one has to invoke the linker manually anyway). However, rustc will not try to enable LTO for its own linker invocations yet.

@rust-lang/infra, llvm-objdump does not seem to be built by default. Can I just add it? And if so, how?

@alexcrichton

I think that llvm-objdump is probably already compiled it's just not in PATH I think? It shoudl be fine though to tweak rustbuild to put the llvm bin dir in PATH when invoking compiletest

I can find llvm-objdump in ./build/<target>/llvm/bin/llvm-objdump.

I'm calling it like this:

OBJDUMP=$(HOST_RPATH_DIR)/../../llvm/bin/llvm-objdump

So it should not need to be in PATH?

Oh, but maybe we are not building LLVM ourselves in all cases?

Seems like llvm-objdump prints just __bitcode instead of __LLVM,__bitcode for the section name.

⌛ Testing commit 0bf26bf with merge c88992d...

bors added a commit that referenced this pull request May 7, 2018
@bors
Auto merge of #50000 - michaelwoerister:cross-lang-lto, r=alexcrichton
c88992d 
Add some groundwork for cross-language LTO.

Implements part of #49879:
- Adds a `-Z cross-lang-lto` flag to rustc
- Makes sure that bitcode is embedded in object files if the flag is set.

This should already allow for using cross language LTO for staticlibs (where one has to invoke the linker manually anyway). However, `rustc` will not try to enable LTO for its own linker invocations yet.
