.ll file crashing llc
Run llc -filetype=obj -O0 ppcbug.ll using the attached file ppcbug.ll.
This results in the following assertion error:
Unsupported Modifier
UNREACHABLE executed at
/home/u0012540/llvm/lib/Target/PowerPC/MCTargetDesc/PPCELFObjectWriter.cpp:303!
Root cause seems to be the debug info for the TLS variable.
LLVM generates
.quad FE_DFL_ENV@DTPOFF
Similar C code generates with ggc:
.quad FE_DFL_ENV@dtprel+0x8000</pre>
