The names hash to the NIDs dbOlWdppb4o and vieBRwlh1Lw that the exports
carried as sceAgcUnknownCreateInterpolantMapping and
sceAgcUnknown_vieBRwlh1Lw.

sceAgcCreateInterpolantMapping resolved the pixel shader's ABI, which takes
the process-wide shader preparation lock until the scope ends, and then
waited under that lock for the vertex shader's background registration
preparation. sceAgcCreatePrimState and sceAgcLinkShaders could wait the same
way. Every other shader registration and ABI resolution queued behind that
one compile: on PPSA07411 the lock was held 8 to 10 s of every 10 s, almost
all of it waiting for registration preparations, while its loader threads
waited 13 to 45 s per 10 s to take it.
A preparation scope now names the shaders it resolves and waits for their
registration preparations before it can take the lock.

Report the 8-byte GS primitive payload when the shader's context registers
set SPI_SHADER_IDX_FORMAT.IDX0_EXPORT_FORMAT to SPI_SHADER_2COMP, and 0
otherwise. The search runs over every context register, so an earlier
SPI_SHADER_IDX_FORMAT entry with another format does not end it.

Apple clang ships libc++, which differs from libstdc++ where the sources
relied on it:
- std::atomic<std::shared_ptr<T>> is not provided. AtomicSharedPtr is that
type where the library has it and a mutex-guarded pointer with the same
member functions elsewhere; the AGC driver uses it.
- std::atomic_ref<const T> is not provided; the page span reads go through
a non-const reference.
- std::filesystem::file_time_type::clock::to_sys is not provided;
std::chrono::file_clock::to_sys is.
- std::max and std::min do not deduce across the integer types of the
guest range arithmetic, which is spelled with an explicit type.
- <string> and <initializer_list> are included where the sources and tests
use them.
Hollow Knight Silksong (PPSA12544) imports libSceAgc NID vieBRwlh1Lw
(#699). Its name is unknown: it is not in aerolib, and the
sceAgcUpdateInterpolantMapping label other projects give it hashes to
SbuY2jN+axQ.
OpenAGC (src/game_compat.c at 3c7e807, sceAgcUnknownVieBRwlh1Lw) reads
it from FW 11.60 as the dbOlWdppb4o transform with the same (regs, gs,
ps) arguments, without the identity tail: it writes one register per
pixel shader input, none for a pixel shader without inputs, and rejects
a null pixel shader. It now shares the dbOlWdppb4o path and throws for
the rejected arguments.
For is_f16 1 and 3 inputs whose default_value and default_value_hi
differ, OpenAGC takes DEFAULT_VAL from default_value_hi, while KytyPS5,
sharpemu and dbOlWdppb4o here take it from default_value; these inputs
throw. On every other input the dbOlWdppb4o values equal OpenAGC's.
agc_interpolant_mapping runs the dbOlWdppb4o vectors and OpenAGC's
enhanced-mapping vectors through it.

EVO Player (PPSA99039), Jelly5 (PPSA99505), Emby5 (PPSA99515) and
Nuvio PS5 (PPSA99997) stop on main 0f863c10 with
what(): sceAgcCreatePrimState: invalid user configuration register offsets
All four build their shader headers by hand (EVO-PLAYER-PS5
evo_agc_shader_header.c, ported from ps5-xash3d-halflife) and store the
ge_user_vgpr_en special at 0x25c (GE_USER_VGPR1, value 0) instead of
0x262 (GE_USER_VGPR_EN), as analysed in #3457. They run on the console.
OpenAGC's reconstruction of the FW 5.50 sceAgcCreatePrimState
(src/game_compat.c at 3c7e8072) copies the four special register pairs
verbatim without checking their offsets; KytyPS5's offset checks
(src/libs/agc.cpp at 16a7fe68) are EXIT_NOT_IMPLEMENTED guards. The
special is now copied at the offset the header stores, not moved to
0x262; the driver reads neither register. GE_CNTL, VGT_SHADER_STAGES_EN
and a used VGT_GS_OUT_PRIM_TYPE are still required at their own
offsets because the driver reads them there, and the error now names
the special and the offset found.
With the change all four titles get past sceAgcCreatePrimState and stop
in the shader recompiler (GetImageResource dword 3 is not a valid
runtime value), as #3457 reported for EVO Player.

(cherry picked from commit aeaa5080d9595305aa73e74d966f989c88b79839)
sceAgcCreatePrimState only packs registers, but it now also resolves the
graphics ABI ahead of time, and that resolve throws when the primitive
type is a patch list without HS_EN or a hull stage with another type.
No draw can use such a state, so leave it to draw time and return the
registers. Bit 2 of VGT_SHADER_STAGES_EN is HS_EN, not an NGG bit.

PPSA26344 imports libSceAgc NID dbOlWdppb4o, whose name is unknown,
and calls it with the (regs, gs, ps) arguments of
sceAgcCreateInterpolantMapping to fill the 32 SPI_PS_INPUT_CNTL
registers. It is exported as sceAgcUnknownCreateInterpolantMapping.
It differs from sceAgcCreateInterpolantMapping only for inputs that
carry the high f16 half alone (is_f16 2): these take the default bit
and DEFAULT_VAL from the high half, as KytyPS5 does.
Both exports share validation and the register loop. More than 32
pixel shader inputs now throw; before, they were written past the
32-register block. agc_interpolant_mapping covers both exports.
