riscv-as

A tiny and simple RISC-V assembler.

Building - RP2350

The assembler includes a CMakeLists.txt that makes it a library for any RP2350 project!
If you want to use it just clone the repository inside your project:

$ git clone https://github.com/semitov/riscv-as.git

Include the directory (CMakeLists.txt):

add_subdirectory(riscv-as)

Then link it in your project (CMakeLists.txt):

target_link_libraries(your_cool_project PUBLIC stv-assembler ...)

In the end you probably will need the files instruction.c and writer.c to use its functions, but fill free to hack it as you prefer!

NOTE : Don't forget to define the macro PICO_BUILD to build it correctly.

Building - Native

To build it (and use it) natively on any host PC simply use our meson build system:

$ meson setup build
$ cd build
$ meson compile

Usage

$ ./semitov-riscv-as -c source_file.s -o output_binary

Testing

If you want to test the generated binaries with spike and/or pk, you need a RISC-V toolchain.

• Recommended: prebuilt riscv-gnu-toolchain-builds.
• Alternative: build the riscv-gnu-toolchain yourself with multilib enabled.

Note: pk should be built for 32-bit targets.
