Pull request overview
Bumps the Arm backend’s tosa-tools dependency to the 2026.05 release and introduces a tosa_dev_mode compile spec flag to enable experimental/dev-version serialization for improved (de)serialization compatibility across tooling versions.
Changes:
- Bump
tosa-toolsfrom2026.2.1to2026.5.0in Arm/VGF dependency sets. - Add
tosa_dev_modetoArmCompileSpec, propagate it through compile-spec filtering, and enable it by default forVgfCompileSpec. - Add the TOSA 1.1 FlatBuffers schema (
tosa_1.1.fbs) and add a unit test ensuringtosa_dev_moderound-trips through compile spec serialization.
