Remove some variables but call functions for side effects
This patch consolidates the (possibly-questionable) spots where we remove a declaration but continue to call some function for side effects. In a couple of cases it wasn't entirely clear to me that this mattered; and in some other cases it might be more aesthetically pleasing to use ATTRIBUTE_UNUSED. So, I broke this out into a separate patch for simpler review. 2016-07-14 Tom Tromey <tom@tromey.com> * arch-utils.c (default_skip_permanent_breakpoint): Remove "bp_insn". * disasm.c (do_assembly_only): Remove "num_displayed". * dwarf2read.c (read_abbrev_offset): Remove "length". (dwarf_decode_macro_bytes) <DW_MACINFO_vendor_ext>: Remove "constant". * m32c-tdep.c (make_regs): Remove "r2hl", "r3hl", and "intbhl". * microblaze-tdep.c (microblaze_frame_cache): Remove "func". * tracefile.c (trace_save): Remove "status".
