Compiler choked on the first file it tries to compile: gcc added
-mips1 automatically to the as command line which conflicts with the
-Wa,--trap option:
/usr/local/lib/gcc-lib/mips-linux/3.2.2/../../../../mips-linux/bin/as
-G 0 -O2 -g0 -32 -march=r4100 -v -mips1 -non_shared -32 -march=r4100
--trap -o scripts/.tmp_empty.o -
Assembler messages:
Error: trap exception not supported at ISA 1
Removing the line which unsets the gas_isa option makes it work again:
/usr/local/lib/gcc-lib/mips-linux/3.2.2/../../../../mips-linux/bin/as
-G 0 -O2 -g0 -32 -march=r4100 -v -mips1 -non_shared -32 -march=r4100
-mips3 --trap -o scripts/.tmp_empty.o
