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).

* - Macro
|
|
- Description
|
|
* - ``__AMDGPU__``
|
|
- Indicates that the code is being compiled for an AMD GPU.
|
|
* - ``__AMDGCN__``
|
|
- Defined if the GPU target is AMDGCN.
|
|
* - ``__R600__``
|
|
- Defined if the GPU target is R600.
|
|
* - ``__<ArchName>__``
|
|
- Defined with the name of the architecture (e.g., ``__gfx906__`` for the gfx906 architecture).
|
|
* - ``__<GFXN>__``
|
|
- Defines the GFX family (e.g., for gfx906, this macro would be ``__GFX9__``).
|
|
* - ``__amdgcn_processor__``
|
|
- Defined with the processor name as a string (e.g., ``"gfx906"``).
|
|
* - ``__amdgcn_target_id__``
|
|
- Defined with the target ID as a string.
|
|
* - ``__amdgcn_feature_<feature-name>__``
|
|
- Defined for each supported target feature. The value is 1 if the feature is enabled and 0 if it is disabled. Allowed feature names are sramecc and xnack.
|
|
* - ``__AMDGCN_CUMODE__``
|
|
- Defined as 1 if the CU mode is enabled and 0 if the WGP mode is enabled.
|
|
* - ``__AMDGCN_UNSAFE_FP_ATOMICS__``
|
|
- Defined if unsafe floating-point atomics are allowed.
|
|
* - ``__AMDGCN_WAVEFRONT_SIZE__``
|
|
- Defines the wavefront size. Allowed values are 32 and 64 (deprecated).
|
|
* - ``__AMDGCN_WAVEFRONT_SIZE``
|
|
- Alias to ``__AMDGCN_WAVEFRONT_SIZE__`` (deprecated).
|
|
* - ``__HAS_FMAF__``
|
|
- Defined if FMAF instruction is available (deprecated).
|
|
* - ``__HAS_LDEXPF__``
|
|
- Defined if LDEXPF instruction is available (deprecated).
|
|
* - ``__HAS_FP64__``
|
|
- Defined if FP64 instruction is available (deprecated).
|

Please note that the specific architecture and feature names will vary depending on the GPU. Also, some macros are deprecated and may be removed in future releases.
