What

Four helpers were defined with identical bodies in the anonymous namespaces of several SPIR-V backend sources:

Helper	Copies
StageOf	SpirvModuleSetup.cpp, SpirvInputOutput.cpp, SpirvDescriptors.cpp
PixelInfo	SpirvModuleSetup.cpp, SpirvInputOutput.cpp, SpirvEmitterHelpers.cpp
VertexInfo	SpirvModuleSetup.cpp, SpirvInputOutput.cpp
ShaderWorkgroupInput	SpirvModuleSetup.cpp, SpirvBufferAccess.cpp

• They are declared once in SpirvEmitterHelpers.hpp, next to FailEmit (refactor(recompiler): share the SPIR-V emission failure helper #832), which they call, and defined in SpirvEmitterHelpers.cpp; bodies and messages are unchanged
• The 9 copies are removed; in SpirvModuleSetup.cpp the anonymous namespace held only these four and is removed
• All changed sources already include SpirvEmitterHelpers.hpp

No behaviour change.

Tested

Windows 11, MinGW-w64 GCC 15.2.0 (WinLibs r7), Release with BUILD_TESTING=ON, on main 80d4f6b. No title or homebrew.

• Full build, no new warnings; ctest: 382/383 passed, the failure is agc_driver_vopc_compare_table fails in wave32 for LG compares in the e32 encoding on AMD RDNA 3.5 #825, which also fails on unmodified main on this AMD GPU.
• The removed text in each file was checked to be exactly the moved body.
• Against the 13 open PRs that touch these files (fix(shader): packed pixel ancillary as SampleId and Layer, gl_Layer via Geometry, Z export formats #295, fix(agc): fragment SampleId, Layer, FragDepth and SampleMask interfaces #375, feat(agc): vertex clip and cull distances #423, GTA V: the prologue plays (testing branch of the PRs it needs) #426, feat(agc): single-sample sample masks as a per-quad-pixel discard #448, perf(agc): baseline shader recompilation on registration #639, feat(shader): implement v_interp_p1ll_f16, v_interp_p1lv_f16 and v_interp_p2_f16 #697, feat(agc): implement image and sampler tables indexed at runtime offsets #757, feat(agc): implement image tables loaded through 64-bit pointers #758, feat(agc): implement deferred faults for reads through null SRT pointers #759, feat(recompiler): implement 64-bit image atomics #896, feat(agc): implement image_load through image tables #920, feat(shader): accept more than 32 buffers per shader up to the device limit #1066), git merge-tree gives no new conflicting file and no conflict hunk in the six changed files; the seven that conflict with main conflict in the same files either way. No open PR adds its own copy of these helpers.
• SPIR-V was not compared byte for byte: there is no switch to dump it, and the tests run with the shader cache off.

Checklist

• Based on current main; no other open PR implements the same functions
• One topic per PR; follow-ups go in a new PR
• No comments in code except technical debt
• Unimplemented paths throw (NotImplemented_nid_no_patch); silent stubs are listed in TechnicalDebt
• No notes, investigation .md files or images added to the repository (attach them to this PR)
• New third-party code is a submodule built from source
• Generic behaviour, not specific to one title
• Depends on: none
• AI-assisted: yes

Checked that the moved bodies and messages match the removed copies and that no other copy is left; build and ctest (395/395) green on the PR merged onto current main, CI green. Merging, thanks.
