Updates
- Implemented a glibc PoC to support setjmp/longjmp for Zicfiss v0.3.1.
The patch can be downloaded for evaluation and review here: https://github.com/bminor/glibc/commit/987dc1ac9ce9dc6776723391c231ed49e36e2e4e
To evaluate the patch, one can build glibc with CFLAGS+="-march=rv64gcv_zicfiss0p3 -menable-experimental-extensions".
This patch has passed validation, and those 6 runtime failures due to lack of setjmp/longjmp support have been fixed.
Further improvement and refactoring for this patch is required for upstreaming.
- A Spike PR, which implements a Zicfiss v0.3.1 instruction subset, was posted for review by Su-Hsien (MediaTek).
The purpose of the PR is to enable compiler validation and collect feedback. PR: https://github.com/riscv-software-src/riscv-isa-sim/pull/1475 - We have implemented setjmp/longjmp in glibc for Zicfiss. Validation is ongoing. It may require refactoring for upstreaming.
