Sometimes the default GCC and newlib libraries built for a given architecture tuple are not based on the desired ABI. Since ABI definitions are different between architectures, the simplest solution is to allow users to build bare-metal toolchains with --enable-multilib. This way, the libraries for every available ABI will be built and users will be able to select the desired library for their user applications. This patch adds the option BR2_TOOLCHAIN_BARE_METAL_BUILDROOT_MULTILIB to give users the choice to enable multilib, if desired. Please note that when using a string of architecture tuples, this option will apply to all architectures in the string, so it can significantly increase build time.

This option allows to define the list of architecture
|
|
tuples for which bare-metal toolchains will be created.
|
|
One toolchain will be built for each of the architecture
|
|
tuples specified in this option.
|
|
|
|
For example, to build both a Microblaze and a RISC-V bare
|
|
metal toolchain, use the following definition:
|
|
"microblazeel-buildroot-elf riscv32-buildroot-elf"
|
|
|
|
config BR2_TOOLCHAIN_BARE_METAL_BUILDROOT_MULTILIB
|
|
bool "Enable multilib"
|
|
help
|
|
Sometimes the default GCC and newlib libraries for a given
|
|
architecture are not the desired ABI. Since ABI
|
|
definitions are different for each architecture, this
|
|
option will enable multilib configuration, so that all
|
|
available ABI libraries are built which will guarantee
|
|
that the desired version will be available for user
|
|
applications.
|
|
|
|
When enabled, this option will apply to all architecture
|
|
tuples in the list.
