support for RISCV32 #2041

Closed ub-tech closed 4 months ago

ub-tech commented 5 months ago

Hi - I'm trying to run a repo with ring as dependency on a RISC32 arch. I tried to override the dependency based on this convo. Is riscv32 supported? Am I trying to implement this override correctly (please see below)? TY very much for any insights.

[patch.crates-io] ring = { git = "https://github.com/leso-kn/ring.git", package = "ring", branch = "riscv64-support-plus-riscv32" }

In target.h, we have:

#elif defined(__riscv) && __SIZEOF_POINTER__ == 8
#define OPENSSL_64_BIT

So presumably we would also need to add the corresponding change for riscv32.

The bigger issue, AFAICT, is that we don't have any way of testing riscv32 code in CI.

See https://github.com/briansmith/ring/pull/2042#issuecomment-2120898907 for an alternative approach.

Please check out PR #2082 to see if this works for you.

Closing this on the assumption that PR #2082 resolves this, at least if you're not using an old version of GCC>
