fix(ci): move Test + Clippy back to ubuntu-latest (unblocks all open PRs)#102
Merged
Conversation
The smithy migration in #91 moved Test and Clippy to self-hosted rust-cpu runners. Both jobs build the entire workspace including synth-verify, which depends on z3-sys — a large C++ compile that fills the smithy runners' /tmp during code generation ("fatal error: No space left on device" on roughly half the z3 AST source files). Every PR opened after #91 landed has been hitting this. Reverting these two jobs to ubuntu-latest (which has ~14 GB /tmp) unblocks every open PR. The other smithy migrations (Z3 Verification, Code Coverage, Rivet Validation, Format) don't build z3 in the same way and stay on smithy. Once the smithy runner image gets a bigger /tmp partition (or libz3-dev preinstalled so z3-sys uses the system lib), move them back.

…x-M (#97) Closes #93 (silicon-blocking). Root cause: `optimizer_bridge::wasm_to_ir` had no handler for `I64ExtendI32U` / `I64ExtendI32S` / `I32WrapI64` — they fell through to `Opcode::Nop`, leaving their result vregs unmapped. The downstream `get_arm_reg` silent R0 fallback caused subsequent i64 shifts to read R0 as their `rm_lo`/`rm_hi` — destroying memset's destination pointer on real silicon. Fix: add the three missing op handlers in wasm_to_ir + ir_to_arm + analyze_i64_local_gets. 5 regression tests added (3 fail-before-pass-after). Format + Rivet failures are smithy-runner crashes (BlobNotFound on logs — same as #102's pattern). Every functional gate passes.

Every open PR opened after #91 landed has been failing Test + Clippy with
fatal error: No space left on deviceduring z3-sys's C++ build. Both jobs build the entire workspace including synth-verify (which depends on z3), and the smithy rust-cpu runners' /tmp can't hold the z3 AST source's intermediate .s files.This reverts just those two jobs back to ubuntu-latest. The other smithy migrations (Z3 Verification, Code Coverage, Rivet Validation, Format) don't build z3 in the same way and stay on smithy.
This unblocks #97 (silicon-blocking memset fix), #96, #99, #100, #101 — all currently failing on the same disk-full error.
Once the smithy runner image gets a bigger /tmp or libz3-dev preinstalled, we can move these back.
