Platform: PC
OS/Version: All
Status: NEW
Severity: normal
Priority: P
Component: Backend: X86

For example, on X86/tls5.ll:
# Machine code for function f:
Function Live Outs: %EAX
0L BB#0: derived from LLVM BB %entry
4L %reg16384<def> = MOV32rm %reg0, 1, %reg0, <ga:@i>[TF=11], %GS<kill>;
mem:l...@i] GR32:%reg16384
12L %EAX<def> = COPY %reg16384<kill>; GR32:%reg16384
20L RET %EAX<imp-use,kill>
# End machine code for function f.
*** Bad machine code: Using an undefined physical register ***
- function: f
- basic block: entry 0x102847198 (BB#0) [0L;32L)
- instruction: 4L %reg16384<def> = MOV32rm %reg0, 1, %reg0, <ga:@i>[TF=11],
%GS<kill>; mem:l...@i] GR32:%reg16384
- operand 5: %GS<kill>
