dwarf2read: Silence -Wenum-compare-switch warning
Compiling with Clang 6 gives:
/home/emaisin/src/binutils-gdb/gdb/dwarf2read.c:24385:14: error: comparison of two values with different enumeration types in switch statement ('enum dwarf_macro_record_type' and 'dwarf_macinfo_record_type') [-Werror,-Wenum-compare-switch]
case DW_MACINFO_vendor_ext:
^~~~~~~~~~~~~~~~~~~~~
/home/emaisin/src/binutils-gdb/gdb/dwarf2read.c:24561:7: error: comparison of two values with different enumeration types in switch statement ('enum dwarf_macro_record_type' and 'dwarf_macinfo_record_type') [-Werror,-Wenum-compare-switch]
case DW_MACINFO_vendor_ext:
^~~~~~~~~~~~~~~~~~~~~
This code uses the two enum types on purpose, because it handles both
.debug_macro and .debug_macinfo sections. Add some pragmas to disable
the warning in these specific cases.
gdb/ChangeLog:
* dwarf2read.c (dwarf_decode_macro_bytes): Ignore
-Wenum-compare-switch warning.
(dwarf_decode_macros): Likewise.
