src/external/gpl3/gcc/dist/gcc/config/riscv: netbsd.h
Log Message:
Re-do previous:
emulate the addition of NETBSD_SUBTARGET_EXTRA_SPECS usually done by
SUBTARGET_EXTRA_SPECS (not used in risc-v) with EXTRA_SPECS.
Go back to using %(netbsd_link_spec) in our link spec, now that it's
a valid string.
Try to mimic other riscv OSes in our LINK_SPEC. they all start with
"-melf" XLEN_SPEC "lriscv" LD_EMUL_SUFFIX
and a definition of LD_EMUL_SUFFIX,
let's copy the LD_EMUL_SUFFIX linux uses.
Now we can link executables.
