Summary: Encountered assembly error due to undefined label `.LcaDcU_info_end` for following code generated by `pprFrameProc`: ``` .Lsat_sa8fp{v}_info_fde_end: .long .Lblock{v caDcU}_info_fde_end-.Lblock{v caDcU}_info_fde .Lblock{v caDcU}_info_fde: .long _nbHlD-.Lsection_frame .quad block{v caDcU}_info-1 .quad .Lblock{v caDcU}_info_end-block{v caDcU}_info+1 .byte 1 ``` This diff fixed the error. Test Plan: ./validate Also the case where we used to have assembly error is now fixed. Unfortunately, I have limited insight here and cannot get a small enough repro or test case for this.

However, blocks within a procedure may > also have info tables, we will dutifully generate debug information for > and consequently we get undefined symbols.
