Ishmam Ahmed 78634fb0a9 feat(relinker): support --trace-imports for Linux output
The Linux entry stub now passes each traced import through libc.prx's
TraceImport_nid_no_patch before it calls the guest entry, and stores the
returned thunk in the import's slot. The same imports are traced as on
Windows: functions bound through a PLT slot or a GOT slot, without an
addend, and not weak. TraceImport_nid_no_patch is bound eagerly through
an added GLOB_DAT relocation, so a libc.prx without it fails at load.
Each slot's page is made writable with mprotect first, so slots inside a
PT_GNU_RELRO range can be replaced.

--trace-imports now requires libc.prx among the libraries on Linux too,
and is refused with --macos.

David 35fe448155 feat(relinker): place macOS executables at a fixed base with --macos-fixed-base
Ruffle (PPSA68091), VLC (PPSA85300) and XPSemu (PPSA97358) read
app0/imports.txt, whose import slot addresses assume the executable's
lowest ELF load page at 0x400000, and dereference them at once. macOS
output always placed that page at 0x140010000, so all three fault on
their first slot read. Linux and Windows have --linux-fixed-base and
--windows-fixed-base for this; macOS had no equivalent.

--macos-fixed-base <address> builds the load image so that the lowest
ELF load page is at the address, as --windows-fixed-base does. The
Mach-O header takes the 64 KiB below it and __PAGEZERO ends there. The
executable is MH_EXECUTE without MH_PIE, so dyld does not slide it. The
address must be 64 KiB aligned, from 0x20000 through 0x7fffffff0000,
and an image ending past the macOS user address space is refused.

Eli Yarson 346b0a92ca feat(relinker): add conversion-time game patches
A per-game relinker-patches.toml (or --patches) replaces verified bytes in
the input executable and bundled modules before conversion. Entries are
checked against the expected bytes and against every in-place writer,
the ELF header range and relocation targets. An <output-stem>.patches.toml
manifest records the applied entries, and --verify-patches checks an input
or a converted output. With no patch file the output is unchanged.

codingreapermapsandClaude Opus 5.5 430e5c833e feat(relinker): add --trace-imports for Windows executables
With --trace-imports the entry stub resolves TraceImport_nid_no_patch
in libc.prx and passes each function import through it before writing
the slot: every PLT slot, and a GOT slot only when the original symbol
is a function, so data imports such as __stdoutp keep their address.
Without the option the output is unchanged.

p3nicillinandClaude Opus 5.5 99efb32c40 feat: convert a title's other executables and start them with sceSystemServiceLoadExec
The relinker's repeatable --executable converts another executable of the
title beside the output, sharing its libs, app0 and guest modules.
sceSystemServiceLoadExec maps /app0 paths to those executables, passes the
argument list on the new command line and finds the main executable through
APS5_EBOOT. RetroArch (PPSA99169) starts its frontend picker this way.

Merijn 1c6eac425d feat(relinker): add --module-dir for modules loaded at run time
Relinks the ELF modules of extra directories under the module parent directory. Modules the executable or another module needs start with the executable; the others are initialized when the title loads them with sceKernelLoadStartModule, with its start arguments (Windows: __aps5_guest_initialize export; Linux: left out of DT_NEEDED).

Squashed onto main by the reviewer (history had a merge commit).

mugurc 92b20608e8 feat(relinker): convert for Rosetta with --to-rosetta
Rosetta runs AVX2, FMA, BMI1/2, F16C and MOVBE, but, unlike an Intel
host, it has neither RDSEED, CLWB nor RDPID. --to-rosetta converts
everything --to-intel does and lowers these three as well:

- RDSEED becomes RDRAND (the /6 form of the same opcode), which also
  returns a random value and sets CF.
- CLWB only writes a cache line back, so it becomes a NOP of the same
  length.
- RDPID becomes a load of 0 through an optional stub: Rosetta's TSC_AUX
  is a constant, not a processor index, so every thread reports
  processor 0. A site with no movable instruction after it for the jump
  is kept.

The flag implies --to-intel and conflicts with --windows. It is
independent of --macos: it only changes what the conversion produces, so
--macos alone leaves these instructions as they are, as on an Intel Mac,
and a title for Rosetta is relinked with --macos --to-rosetta. Intel
output is unchanged: the target is a parameter of the converter, Intel by
default.

mugurc 703989b94b feat(relinker): write Mach-O output for macOS with --macos
The guest image reader and the module builder already produce a
platform-neutral GuestImage; --macos adds a third writer next to the ELF
and PE ones. The executable and every bundled module become x86-64 Mach-O
files (modules as dylibs in app0/sce_module) that run under Rosetta on
Apple silicon.

FreeBSD code reaches its thread pointer through %fs, which macOS cannot
set, so the writer rewrites each %fs access into a stub that reads the
image's thread pointer from a pthread key and allocates the TLS block on
a thread's first access. Dynamic TLS goes through the image's descriptor
instead of __tls_get_addr. Imports bind by NID to the prx libraries
beside the output, exports and TLS imports use the dynamic symbol names,
and the image's metadata lives in __APS5DATA,__meta.

--macos conflicts with --windows. The macOS runtime that consumes the
output (TLS allocation, libraries built for macOS) comes in separate
changes.

STL1teandClaude Opus 5.5 f4f8d5bbce feat(relinker): exclude single sce_module files, tolerate a zero code tail
- --exclude-sce-module <file> (repeatable) drops one title module from
  guest conversion, e.g. a title libc.prx, while the rest of sce_module
  is still relinked as guest modules
- the instruction scanner stops at zero padding that ends a code segment
  with an odd byte instead of failing on a truncated `add [rax], al`

Claude 210987745c Merge upstream main into fix/audit-2026-09
Resolve conflicts with boykopovar/AnyPS5#10 (sce module loading) and
later upstream changes.

- Pthread Cond/Mutex: take upstream. It already releases mutex
  ownership across condition waits, returns ETIMEDOUT 0x8002003C, and
  rejects unlocks from non-owners for every mutex type.
- Pthread Thread: keep upstream's lifecycle, Windows adoption and job
  affinity; re-apply the POSIX fixes on top: reference-counted
  release on join/detach/exit, self-join rejection on both platforms,
  and scePthreadSelf adoption for threads not created by
  scePthreadCreate.
- Semaphore: keep upstream's TimedWait::Condition and wait tracing;
  re-apply sceKernelDeleteSema waking waiters with EACCES.
- Relinker: keep --windows-gui alongside upstream's --skip-sce-module,
  trampoline-aware Patch signature and new Python tests.
