Description
Hi
I am using https://github.com/lowRISC/lowrisc-toolchains/releases/download/20220524-1/lowrisc-toolchain-gcc-rv32imcb-20220524-1.tar.xz as my toolchain to compile riscv code and got the errors like:
these issues are caused by a lack of support for bitmanip? a description in the verification doc says it does support it.
Either download a pre-built toolchain (quicker) or download and build the RISC-V GNU compiler toolchain. For the latter, the Bitmanip patches have to be manually installed to enable support for the Bitmanip draft extension. For further information, checkout the Bitmanip Extension on GitHub and how we create the pre-built toolchains.

Research direction
Start by reproducing the reported errors with the linked lowRISC pre-built toolchain and compare its behavior with the Bitmanip support described in the verification documentation. Review the linked RISC-V GNU toolchain and Bitmanip patch instructions; the issue is done when the release's support status is established and the appropriate documentation or toolchain issue is identified.
