LEB0 and LEB1 are duplicated in the attached ivms assembly file from
libgcc2. Note the first occurrence of each is at the prologue end,
which makes no sense to me.
FYI: I'm emitting the LPE labels at NOTE_INSN_FUNCTION_BEG and the LEB
labels at NOTE_INSN_EPILOGUE_BEG. I can send you the full patch if you
like.
I deleted the .debug* sections to reduce the size of the file.
