[llvm-commits] llvm-gcc on PPC without TARGET_MACHO defined

In llvm-gcc 4.0, "rs6000_output_mi_thunk" in
gcc/config/rs6000/rs6000.c fails to compile unless TARGET_MACHO is
defined. The problem is this block of code:

       /* This JMP is in a coalesced section, and Mach-O forbids us to
          directly reference anything else in a coalesced section; if
          our target gets coalesced away, the linker (static or
          dynamic) won't know where to send our JMP.  Ergo, force a
          stub.  */
       label_decl = add_compiler_branch_island (function, line_number);

which isn't protected by an "#if TARGET_MACHO". I've been working around
the problem using the attached patch, which simply defines
"branch_island_list" whether TARGET_MACHO is attached or not. Is this
the correct fix?
