Ah, I see how it happens now -- "-mipsN" has a higher priority than
"-mcpu=" (but lower than "-march=") so in this case "-mips2" overrides
"-mcpu=vr4100". How about:
GCCFLAGS += -mcpu=vr4100 -Wa,--trap
then?
Ralf, it seems the "-mcpu=XXXX -mipsN" settings are contradicting and
XXXX is ignored (I don't see it as my gcc translates "-mcpu=XXXX" into
"-march=XXXX -mtune=XXXX" as a step towards transiting to 3.x). I think
the following settings would be more reasonable:
GCCFLAGS += -mabi=32 -mcpu=XXXX # for the 32-bit kernel
GCCFLAGS += -mabi=n64 -mcpu=XXXX # for the 64-bit kernel
(additional processor-specific flags skipped). Is that supported by the
oldest version of binutils you want to support?
