verify-patch-sanity.py validates every active recipe .patch has internally- consistent hunk line counts — catching the 'malformed patch at line N' failure at commit/CI/preflight time instead of hours into a cook. This cycle hit that class three times (qtwaylandscanner, sddm, xwayland), each only discovered when cookbook tried to apply the patch. Running it across the repo found 29 latent malformed patches (validated against GNU patch: e.g. relibc/P3-sysv-ipc reproduces 'malformed patch at line 22'). They were harmless only because they sit in vendored recipes (baked, not re- applied) — but would fail on any version-bump re-derivation. --fix recounts the hunk headers (body untouched) and repaired all 29. Wired into build-preflight.sh (Phase 1.0D) and redbear-ci.yml, with a unit test (test-patch-sanity.sh). Skips archived/legacy trees and unvalidatable formats (empty placeholders, bare-@@ git hunks).

// This file tests the -mtp=<mode> functionality in Clang’s ARM driver.
|
||
// It verifies:
|
||
//
|
||
// 1. ARMv7 targets: explicit hardware modes, explicit soft mode, and auto mode.
|
||
// 2. M Profile variants: explicit hardware mode should fail and auto mode defaults to soft.
|
||
// 3. ARMv6 variants: explicit hardware modes on ARMv6K/KZ work, but auto mode falls back to soft when Thumb2 is missing.
|
||
// 4. ARMv5 variants: explicit hardware mode is rejected and auto mode defaults to soft.
|
||
// 5. Miscellaneous error cases (e.g. empty -mtp value).
