- MG_Pipe/PipeInputsSwitch.h is the strangler switch (ARCHITECTURE.md 9.2): MGB_CTX is the
live GLContext in the pull build and &gPipeInputs under MOBILEGL_PIPE_PUSH, so the pull
arm's pGLContext spelling stays outside MG_Backend/ and purity gate C's grep.
- MG_Backend/MGPipe/PipeInputs.h holds one struct with every accessor a backend reads (63:
the 61 Coverage.def rows plus GetBoundTransformFeedbackLifetimeId and
HasOpenTransformFeedbackSpan), each keeping its GLContext name, parameters and return
type so the site conversion is type-neutral; V fields are copied values, O fields are
SharedPtr copies or pointers into the context, the seven F fields forward to the live
context from MG_Impl/Pipe/PipeFill.cpp and are the only sticky ones (Coverage.def's
MGP_COVERAGE_STICKY_LIST argues each: argument-keyed lookups and reverse-channel writes,
never a version or generation counter).
- MG_Pipe/FillPoints.def is the verb table: one row per GLFunctionsTable function pointer in
declaration order (69), nine classes and the may-read field rows; gen_pipe.py parses the
struct and refuses a row set that is not exactly its member set, then emits
generated/PipeFillPoints.inc (verb enum, class tables, per-class field masks with the
sticky fields OR'ed in). MGP_FILL(Verb) in MG_Impl/Pipe/PipeFill.h is the fill point;
MGPipeFillForVerb only bumps the serial, records the verb and stamps the sticky fields
here - the per-class copies land in the next commit, the fill points in MG_Impl after.
- MOBILEGL_PIPE_POISON is derived once in PipeInputs.h from MOBILEGL_PIPE_PUSH and the DEBUG
level, MOBILEGL_BUILD_DISAGGREGATED or MOBILEGL_PIPE_VERIFY (the tree has no
MOBILEGL_DEBUG); under it every accessor is a read-side freshness check that aborts with
Fatal{UnmigratedPipeInput, "Field@Verb"}.
- CMake: MOBILEGL_PIPE_PUSH and MOBILEGL_PIPE_VERIFY options (VERIFY forces PUSH on), the two
new sources appended only under PUSH, the compile definitions; Config.h/ConfigLoader.cpp
gain PipeVerifyFatal / PipeVerifyCorrupt / PipePoisonOmit under #if MOBILEGL_PIPE_PUSH so
the pull build's FeaturesTable does not change size.
- Pull build proof: symbol_report.py against the 087685d1 baseline reports 0 added / 0
removed / 0 resized / 0 renamed and a .text delta of 0; ctest -N names unchanged; gen_pipe
--check clean; unit tests green in the pull, push and verify builds.
