The fork (4560e6b) resolves paths as the Qt application does, answers the image and photo callbacks, releases a waiter's mutex around its wait callback in the atomic wait engine (EDEADLK on the console's error-checking mutexes), and gives the RetroPads the handler's own bindings. The LLVM fork (98b45cc) lays out TrailingObjects classes as other targets do: the PS5 ABI ignores alignas on their empty aligner base, and each allocation came up 4 bytes short (SPU compiles crashed in MachineInstr::hasOrderedMemoryRef). The title's crash report now prints every register, the heap words around them, and the code addresses on the crashing stack up to its top. God of War HD boots to its first level at 100% and 300%, every 10 s window after the boot at 100% (docs/PHASE_LOG.md).

# Build LLVM for the PS5 as static archives, for RPCS3's PPU and SPU
|
|
# recompilers (docs/RPCS3_PORT.md).
|
|
#
|
|
# The source is my fork of llvm-project, PS5_LLVM (github.com/mihawk-99/PS5_LLVM),
|
|
# whose main is llvmorg-22.1.8 -- the revision RPCS3 pins as its
|
|
# 3rdparty/llvm/llvm submodule -- plus the changes the console's ABI needs
|
|
# (SmallVector's alignment). It is fetched sparsely and built once, outside
|
|
# RPCS3's tree, so a change to RPCS3 never rebuilds LLVM:
|
|
# X86 only, no tools, tests, docs or examples, no zlib, zstd, libxml2 or
|
|
# network, no crash-signal handlers of LLVM's own (the title reports crashes),
|
|
# with ccache. The code generators LLVM's build runs (llvm-tblgen and
|
|
# llvm-min-tblgen) are built for the host first, from the same tree, so the
|
|
# console build defines no tablegen programs of its own.
|
|
#
|
|
# Output: .deps/native/llvm-ps5 (lib/*.a, include/, lib/cmake/llvm), with the
|
|
# revision in .deps/native/llvm-ps5/.revision.
