v1.126.0

Highlights

• Add nine conservative advisories: dense GEMM zero suffixes (PS6129), SIMD coefficient-address setup (PS6130), stale measured dispatch crossover evidence (PS6131), maximum-row transient workspace (PS6132), offset-inflated row-local guards (PS6133), capacity-wide active-bound fallbacks (PS6135), retained maximum-context output workspace (PS6136), reusable native snapshot output (PS6137), and ARM64 shift/mask extraction chains (PS6138).
• Preserve exact fixed-count allocation totals and verify matched, source-pinned allocation campaigns end to end.
• Strengthen xctrace artifact qualification and workload-input preflight. The separate cmd/tracecapture tool now supports bounded direct-executable attachment and cleanup; it is not included in the release archives.
• Normalize version output to version-only tokens and improve parallel test execution, deterministic retry tests, cancellation and corrupt-evidence rejection without removing test coverage.
• Parallelize bounded test-name discovery, reject stale typed inputs before controlled builds, and reduce allocation overhead in binary-material directive scanning while preserving source hashing and independent post-build validation.

These advisories do not apply lifetime-changing or architecture-specific rewrites automatically. Configured domain rules require their documented source, geometry and native-operation evidence. Attributed owner measurements are not universal speedup predictions.

Installation

Download a platform archive, or install the root command with:

go install github.com/jxsl13/perfscan@v1.126.0

Archives contain perfscan for Linux, macOS and Windows on amd64 and arm64. Checksums are provided separately. Version tags have no path prefix; no perfscanxx command is shipped.
