2023-07-11Add --with-extra-multilib-test optionKito Cheng1-0/+15
NOTE: This is toolchain developer facing feature. This allow user to add extra testing multi-lib arch, it's useful when develop and/or testing new extensions. Usage: --with-extra-multilib-test="arch-abi[;arch-abi]" e.g. linux enable enabled multilib, so default will build with follwoing configuration: lib32/ilp32;@march=rv32imac@mabi=ilp32 lib32/ilp32d;@march=rv32imafdc@mabi=ilp32d lib64/lp64;@march=rv64imac@mabi=lp64 lib64/lp64d;@march=rv64imafdc@mabi=lp64d But you want to testing more on vector stuffs like rv32gcv and rv64gcv, then you can configure with `--with-extra-multilib-test="rv32gcv-ilp32d;rv64gcv;lp64d"` Then the testing will run rv32imac-ilp32 rv32imafdc-ilp32d rv64imac-lp64 rv64imafdc-lp64d and rv32gcv-ilp32d;rv64gcv;lp64d! NOTE: Extra multilib test settings still require existing multilib has support those extra settings, e.g. you can't add rv32imafc_zbb-ilp32f on above example since no compatible multilib has provided.

2023-05-17Add support to build LLVM/clang with C and C++ supportChristoph Müllner1-5/+37
We currently have a stale "llvm" branch, that does not build. However, there is clear demand in the RISC-V toolchain community for a working LLVM on top of a recent GNU toolchain. In order to build such a toolchain, quite some LLVM and clang know-how is required to avoid path issues at LLVM build time or later when using clang. The main purpose of this commit is to demonstrate a way to combine the RISC-V GNU toolchain repo with LLVM, with the intent to save others hours of frustration, debugging time or support time.

2022-02-24Prevent musl riscv32 buildsFlorian Hofhammer1-5/+10
The upstream musl libc does not support 32bit RISC-V builds. We therefore only allow building the 64bit version (i.e., riscv64-unknown-linux-musl-). Signed-off-by: Florian Hofhammer <florian.hofhammer@fhofhammer.de>

Just updating previous PR as `mpc` is a music player, `libmpc` is the correct required package.

2020-12-29Update README.md for clear instructions on multilibioannesKX1-6/+8
The current README.md only explains how to use multilib on the Linux cross-compiler, but not on the Newlib one. This might create confusion as seen here https://github.com/riscv/riscv-tools/issues/287, or makes it seem like you can't multilib on Newlib. It's also the case that the multilib option is more common on embedded toolchains rather than on Linux, so I believe this small change on documentation should clear things up.
