Hi --
I'm seeing failures building gdb-head for MIPS targets. The
failure are warnings while compiling the MIPS opcode tables. Gdb
is built with -Werror and the tables have missing initializers for
the 'exclusions' field.
Is anyone else seeing this build failure? If not, what are
you doing different from a minimal configuration?
The fix is trivial: add 0 initializers for the missing field.
Is anyone else working on this?

There are special makefile rules to handle this:
micromips-opc.lo: micromips-opc.c
$(LTCOMPILE) $(NO_WMISSING_FIELD_INITIALIZERS) -c -o $@ $<
mips-opc.lo: mips-opc.c
$(LTCOMPILE) $(NO_WMISSING_FIELD_INITIALIZERS) -c -o $@ $<
mips16-opc.lo: mips16-opc.c
$(LTCOMPILE) $(NO_WMISSING_FIELD_INITIALIZERS) -c -o $@ $<
Not sure why it isn't working for gdb though.

Thanks. That was enough of a clue.
I was picking up an old version of gcc which did not support
-Wno-missing-field-initializers. The makefile set
$NO_WMISSING_FIELD_INITIALIZERS to null.

That looks like an issue to me, what version of GCC was that? Perhaps we
should resort to -Wno-error for NO_WMISSING_FIELD_INITIALIZERS if the
actual option is not supported.
