@ -547,6 +547,20 @@ The commands will all be named using the prefix `riscv32-unknown-elf-`, which
makes it easy to install them side-by-side with the regular riscv-tools (those
are using the name prefix `riscv64-unknown-elf-` by default).
The following make targets build toolchains for `RV32I[M][C]` using this sequence
of commands (not including installing prerequisites):
| Command | Install Directory | ISA |
|:---------------------------------------- |:------------------ |:-------- |
| `make -j$(nproc) build-riscv32i-tools` | `/opt/riscv32i/` | `RV32I` |
| `make -j$(nproc) build-riscv32ic-tools` | `/opt/riscv32ic/` | `RV32IC` |
| `make -j$(nproc) build-riscv32im-tools` | `/opt/riscv32im/` | `RV32IM` |
| `make -j$(nproc) build-riscv32imc-tools` | `/opt/riscv32imc/` | `RV32IMC` |
By default calling any of those make targets will (re-)download the toolchain
sources. Run `make download-tools` to download the sources to `/var/cache/distfiles/`
once in advance.
