help
If your target CPU does not have a Floating Point Unit (FPU) or a
kernel FPU emulator, but you still wish to support floating point
functions, then everything will need to be compiled with soft floating
point support (-msoft-float).
Most people will answer N.

depends on HAS_MIPS16
default y
help
If your target CPU does support the MIPS16 instruction set
and you want to use it for packages, enable this option.
MIPS16 produces smaller binaries thus reducing pressure on
caches and TLB.
Most people will answer N.

Specify the libc type used by the external toolchain. The given value
is passed as -m flag to all gcc and g++ invocations. This is mainly
intended for multilib toolchains which support glibc and uclibc at
the same time. If no value is specified, no -m flag is passed.

If you're specifying an addition target architecture,

specify -m64 here.

musl: improve crypt() size hack Instead of silently downgrading any non-MD5 crypt() request to DES, cleanly fail with return NULL and errno = ENOSYS. This allows callers to notice the missing support instead of the unwanted silent fallback to DES. Also add a menuconfig toolchain option to optionally disable the crypt size hack completely. This can be probably made dependant on SMALL_FLASH or a similar feature indicator in a future commit. Ref: https://github.com/openwrt/openwrt/pull/1331 Signed-off-by: Jo-Philipp Wich <jo@mein.io>
