# Buildroot backend specific options
if BR2_TOOLCHAIN_BUILDROOT
comment "Toolchain Options"
config BR2_TOOLCHAIN_BUILDROOT_LARGEFILE
bool "Enable large file (files > 2 GB) support"
select BR2_LARGEFILE
help
Enable this option if you want your toolchain to support
files bigger than 2 GB.
config BR2_TOOLCHAIN_BUILDROOT_INET_IPV6
bool "Enable IPv6 support"
select BR2_INET_IPV6
help
Enable this option if you want your toolchain to support
IPv6.
config BR2_TOOLCHAIN_BUILDROOT_INET_RPC
bool "Enable RPC support"
select BR2_INET_RPC
help
Enable this option if you want your toolchain to support
RPC (needed for NFS, for example).
config BR2_TOOLCHAIN_BUILDROOT_WCHAR
bool "Enable WCHAR support"
select BR2_USE_WCHAR
help
Enable this option if you want your toolchain to support
wide characters (i.e characters longer than 8 bits, needed
for locale support).
config BR2_TOOLCHAIN_BUILDROOT_LOCALE
bool "Enable toolchain locale/i18n support"
select BR2_TOOLCHAIN_BUILDROOT_WCHAR
select BR2_ENABLE_LOCALE
help
Enable this option if you want your toolchain to support
localization and internationalization.

help
Enable this option if you want your toolchain to support the
C++ language and you want C++ libraries to be installed on
your target system.

Enable stack smashing protection support using GCCs
-fstack-protector[-all] option.

help
Use this option to select the thread library implementation
that should be used in your toolchain. Not all thread
variants work with all versions of uClibc, the "linuxthreads
(stable/old)" may be a working fallback if you need
threading at all.

config BR2_VFP_FLOAT
bool "Use ARM Vector Floating Point unit"
depends on !BR2_SOFT_FLOAT
depends on BR2_arm || BR2_armeb
help
Setting this option will enable the "-mfpu=vfp" option.
If your ARM CPU has a Vector Floating Point Unit (VFP)
and the toolchain supports the option, then the
code can be optimized.
Most people will answer N.
