RISC-V: Add configure option: --with-multilib-generator to flexible config multi-lib settings.
- Able to configure complex multi-lib rule in configure time, without modify
any in-tree source.
- I was consider to implmenet this into `--with-multilib-list` option,
but I am not sure who will using that with riscv*-*-elf*, so I decide to
using another option name for that.
- --with-multilib-generator will pass arguments to multilib-generator, and
then using the generated multi-lib config file to build the toolchain.
e.g. Build riscv gcc, default arch/abi is rv64gc/lp64, and build multilib
for rv32imafd/ilp32 and rv32i/ilp32; rv32ic/ilp32 will reuse
rv32i/ilp32.
$ <GCC-SRC>/configure \
--target=riscv64-elf \
--with-arch=rv64gc --with-abi=lp64 \
--with-multilib-generator=rv32i-ilp32--c;rv32imafd-ilp32--
V3 Changes:
- Rename --with-multilib-config to --with-multilib-generator
- Check --with-multilib-generator and --with-multilib-list can't be used at
same time.
V2 Changes:
- Fix --with-multilib-config hanling on non riscv*-*-elf* triple.
gcc/ChangeLog:
* config.gcc (riscv*-*-*): Handle --with-multilib-generator.
* configure: Regen.
* configure.ac: Add --with-multilib-generator.
* config/riscv/multilib-generator: Exit when parsing arch string error.
* config/riscv/t-withmultilib-generator: New.
* doc/install.texi: Document --with-multilib-generator.
