<pre>I noticed the clang tests recently started hitting an assertion failure for me
(because I build it as a shared library). I tracked that down to these symbols
getting the wrong linker type (all should be 'u', so that libclang and libLLVM
will share the same copy of it), and bisected the first culprit to
ce5379f0f0675592fd10a522009fd5b1561ca72b (<a href="https://reviews.llvm.org/D88138">https://reviews.llvm.org/D88138</a>). I
don't fully understand why, as the `.a` files seem to look okay, but it seems
somehow to definitely be the cause (removing Hexagon Codegen from the linker
list, or removing the new code from that PR also fix the problem).
$ ninja lib/libLLVM-12jl.so && nm lib/libLLVM-12jl.so | grep

This specifically causes an abort with any test, such as this, which set
'debug-pass-manager' and run some function pass:
bin/clang -cc1 -internal-isystem lib/clang/12.0.0/include -nostdsysteminc
-triple x86_64-linux-gnu -mllvm -enable-npm-optnone -O0
-fexperimental-new-pass-manager clang/test/CodeGen/O0-no-skipped-passes.c
-fdebug-pass-manager -emit-llvm -o /dev/null -fcoroutines-ts
With a trace like this (and processing it in gdb, I do indeed see that it's of
type _ZN4llvm3Any6TypeIdIPKNS_8FunctionEE2IdE from libclang instead of from
libLLVM):
