<pre>I build Firefox with clang trunk (which I build locally ~weekly), and I noticed
today that I got a build failure with the newest clang trunk.
Specifically:
llvm revision 325568 builds Firefox fine
llvm revision 325569 hits a build error
So I believe this is a regression from grimar's <a href="https://reviews.llvm.org/D43383">https://reviews.llvm.org/D43383</a>
The build error is in the "elfhack" stage of the build, and my output looks
like this:
4:21.16 === If you get failures below, please file a bug describing the error
4:21.16 === and your environment (compiler and linker versions), and
4:21.16 === provide the pre-elfhacked library as an attachment.
4:21.16 === Use --disable-elf-hack until this is fixed.
4:21.16 ===
4:21.17 0x000000000000000c (INIT) 0x4060
4:21.17 test-ctors.so: terminate called after throwing an instance of
'std::runtime_error'
4:21.17 what(): Unsupported relocation type

4:21.28 make[3]: *** [build/unix/elfhack/libs] Error 2
4:21.28 /scratch/work/builds/mozilla-inbound/mozilla/config/recurse.mk:32:

4:21.28 /scratch/work/builds/mozilla-inbound/mozilla/config/rules.mk:434:

4:21.28 make[1]: *** [default] Error 2
4:21.28 client.mk:168: recipe for target 'build' failed
4:21.28 make: *** [build] Error 2
The "Aborted (core dumped)" there looks like it's saying the compiler crashed,
I think....</pre>
