Tested with LLVM trunk, which is at r251181 now.

First, r247309 causes Rust bootstrap to fail. (r247352 is a followup warning fix.) Revert the patch to test.

svn diff -c -247352 | patch -p0
svn diff -c -247309 | patch -p0

Second, run-make/target-specs fails. Otherwise, all tests pass.

tl;dr: If It fails for me at a linking step (eg. ld: cannot find -lLLVMAsmParser) but I'm probably misunderstanding something (like, do I have to revert some llvm patches before testing?)

Testing with system llvm (so, not the llvm that comes with rust)
Note: I'm testing with my current outdated llvm(3.7.0) first, and then with the latest master(aka trunk) llvm.

$ llc --version
LLVM (http://llvm.org/):
  LLVM version 3.7.0
  Optimized build.
  Default target: x86_64-pc-linux-gnu
  Host CPU: (unknown)

  Registered Targets:
    amdgcn - AMD GCN GPUs
    cpp    - C++ backend
    r600   - AMD GPUs HD2XXX-HD6XXX
    x86    - 32-bit X86: Pentium-Pro and above
    x86-64 - 64-bit X86: EM64T and AMD64

...

That llvm_only_x86_64.patch is https://github.com/zazdxscf/gentooskyline/blob/a7c195c38f9315e09976801614760c30ad77dc3f/system/Z575/OSes/gentoo/on_baremetal/filesystem_now/gentoo/home/zazdxscf/build/1nonpkgs/rust/llvm_only_x86_64.patch
which only makes sure rust doesn't compile for any other arch than x86_64 (also applies to the llvm that comes with rust). So in a way, that makes this testing incomplete, for it only tests for x86_64.

I forgot why this is happening... but this is why I needed my llvm_only_x86_64.patch to avoid this!
EDIT2: Ah yes, it is because llvm was compiled for host-only (so in gentoo the USE=-multitarget is the default, which means host-only, so no arm, powerpc support unless I recompile with that USE flag turned on)

The latest commit of my installed system llvm is llvm-mirror/llvm@3f3f65a (it doesn't deal with svn on gentoo, which is what I'm using)

Sorry, I did not understand #29272 (comment)
Do I have to revert both or only the first of those patches, before testing rust? (currently reverted neither)
(I forgot how to look at a certain llvm svn revision(on the web), without actually having to clone the entire svn repo locally, in order to then find the llvm commit in the github mirror https://github.com/llvm-mirror/llvm by searching for it by commit description and then getting it as patch by appending .patch to the url, to then use to reverse it from the llvm git that comes with gentoo before recompiling it) EDIT:(I just git log my local gentoo llvm git repo at /usr/portage/distfiles/git3-src/llvm.git and search for revision number)

Oh wait, is 247352 this one? llvm-mirror/llvm@4d0f917

EDIT: 247309 is this: llvm-mirror/llvm@5d8f37f

I try a simple test (least ./configure args) -- same linking error.

Thanks @sanxiyn! I've actually also been trying to upgrade LLVM to see if we can start using the new SEH instructions support for MSVC 32-bit, and the reason we can't bootstrap is actually quite familiar as the fix is the same as a previous commit basically. For now though seems fine to upgrade our C++ support!

@zazdxscf The linking failures are the issue discussed in #28327 and at https://internals.rust-lang.org/t/meaning-of-link-kinds/2686.

Edit: And the 3.7.0 compile failure is #28830.
