# Companion libraries config options

# and can be used by binutils and gdb (maybe others as well).

gcc 4.3.0 and above requires both GMP and MPFR to build some frontends,
and some other components can use them as well.
These will be automatically selected if you choose gcc>=4.3.0, but you
can say 'Y' here if you want to build those two libraries for the other
components (that don't select them by default).
The packages that can use GMP and MPFR are:
- binutils
- gcc
- gdb

Also build libraries for the target. This can be usefull if you want
to later build a compiler that will run on the target, or if you want
to run gdb natively on the target.

gcc-4.4.0 and above requires PPL and CLooG/PPL to build some parts
of the optimiser (GRAPHITE loop optimisation, to be precise).
In addition to those, gcc-4.4 also optionally uses MPC to enable
additional optimisations on complex numbers. Although MPC is optional,
crosstool-NG requires it and uses it to build gcc >= 4.4.0.
These will be automatically selected if you choose gcc>=4.4.0, but you
can say 'Y' here, although it is unknown yet if any other component
can use them.
