  --with(out)-synci
  --with(out)-mips-plt
  --with-divide=type

config CC_GCC_mips_llsc
tristate
prompt "Use llsc"
default m
help
This configures how gcc will emit load-link, store-conditional and
sync opcodes. Normally, you'd set this to 'M', and configure will do
the correct thing (ie. enable llsc for Linux-based targets, disable
for others). If you know better, you can force either using llsc or
not using it (resp. 'Y' or 'N').
config CC_GCC_mips_synci
tristate
prompt "Use synci"
default m
help
This configures how gcc will emit the synci opcode. Normally, you'd
set this to 'M', and configure will do the correct thing (ie. disable).
If you know better, you can force using synci (say 'Y'), or not using
it (say 'N').
config CC_GCC_mips_plt
bool
prompt "Use copy relocations & PLTs"
help
This configures gcc to use copy relocations & PLTs. These are
extensions to the traditional SVR4-based MIPS ABIs and require
support from GNU binutils and the runtime C library.
Say 'N' to keep the default and not use them, say 'Y' to use them.
