Host logging opens its own FILE on the saved descriptor. The guest FILE stays on the replaced descriptor, so guest printf, puts and fprintf still reach the pipe.
Implement sceRudpPollCreate, sceRudpPollControl, sceRudpPollWait and
sceRudpPollDestroy with the PS Vita signatures and argument checks.
sceRudpTerminate removes the context from every poll and sceRudpEnd
destroys the polls and wakes their waiters.

Move the guest_move registration in core/libs/CMakeLists.txt next to the
voice tests so it no longer shares lines with the netctl access point
tests that another open pull request adds.

Add sceMoveInit, sceMoveTerm, sceMoveOpen, sceMoveGetDeviceInfo and
sceMoveSetVibration, and replace the throwing stubs of the other six
exports. Behaviour and error codes follow shadPS4; signatures follow
Orbital. A guest test covers the init state, argument checks and the
no-controller results.

Adds tests for nine implemented libSceRudp functions that previously
lacked coverage:
- sceRudpActivate (returns 0 always)
- sceRudpEnableInternalIOThread (NOT_INITIALIZED before init, 0 after)
- sceRudpSetEventHandler (returns 0)
- sceRudpBind (NOT_INITIALIZED, INVALID_CONTEXT_ID, 0 on success)
- sceRudpSetOption (NOT_INITIALIZED, INVALID_CONTEXT_ID, 0 on success)
- sceRudpInitiate (NOT_INITIALIZED, INVALID_CONTEXT_ID, CONN_REFUSED)
- sceRudpGetContextStatus (NOT_INITIALIZED, INVALID_CONTEXT_ID, fills
status with 0, null status allowed)
- sceRudpWrite (NOT_INITIALIZED, INVALID_CONTEXT_ID, CONN_RESET)
- sceRudpRead (NOT_INITIALIZED, INVALID_CONTEXT_ID, CONN_RESET)
Each assertion mirrors the exact implementation in Export.cpp. Error
codes and return values are the constants hardcoded in the source.
No console measurement needed — these are pure offline behaviors.

The nid_patcher turns each *_nid_no_patch_cut alias into a second dynamic
symbol with the same name as the plain alias exported next to it, seven
names in all. With those duplicates, LD_DEBUG=bindings shows libstdc++ keeping its own __cxa_allocate_exception, __cxa_throw,
__cxa_begin_catch, __cxa_end_catch, __cxa_rethrow, __gxx_personality_v0
and _Unwind_Resume while taking __cxa_init_primary_exception,
_Unwind_RaiseException and std::terminate from libc.prx. An exception
thrown inside libstdc++ (std::stoi, a stream with exceptions enabled) got
a libc header laid over a libstdc++ allocation, reached the libc
personality as a foreign exception, matched no typed handler and ended in
"terminate called without an active exception". The plain aliases already
export these names, so the duplicates go.
libstdc++ also describes std::__ios_failure with __iosfail_type_info, a
class that privately derives from __si_class_type_info at the same
address. Kind now follows such single same-address bases to the
__cxxabiv1 class, so catching std::ios_base::failure or std::exception
matches a stream failure.
The plain aliases came in a4c519b26 next to the cut aliases from
14f8c16ac.
Unreal titles end in their own libc fatal path with the UTF-16
LowLevelFatalError message in a register, and the crash report shows
only the first 64 bytes of it as hex words, so the message is lost
(#4238: Demon Slayer PPSA03490, Stray PPSA02100).
For every general register that points at readable memory starting
with at least four printable ASCII characters, as UTF-16LE or as single
bytes, the report now prints the text up to a NUL, the first other
character, 512 characters or the end of readable memory (each page is
checked with VirtualQuery before it is read).

sceSaveDataSetSaveDataMemory2 read the whole slot file, patched it and
replaced it through a temporary file on every call, so each call cost a
full rewrite of the slot (up to 32 MiB). The changed ranges now go to a
small journal that is staged through the slot's temporary file and
renamed into place, then written into the slot file in place, and the
journal is removed. A journal left by an interrupted call is replayed by
the next setup, get, set or sync of that slot.

Two defined ELF exports that are renamed to the same name, such as foo
and foo_nid_disambig1, were both written as one name and the patcher
exited 0, leaving a lookup that can reach only one of them. The PE and
Mach-O back ends already reject this.
The ELF patcher now remembers the address (st_value and st_shndx) of
each patched export name and throws "duplicate patched export name"
only when the name comes from a symbol at a different address. Aliases
of one address are kept: the Linux libc defines __cxa_throw and
__cxa_throw_nid_no_patch_cut as aliases of __cxa_throw_nid_postfix, so
both become __cxa_throw, and any lookup of that name resolves to the
same code.
The Linux libc also exported __gxx_personality_v0 twice at different
addresses: the forwarding function in Personality.cpp and the
__gxx_personality_v0_nid_no_patch_cut alias of the guest personality.
Drop that alias, so the name keeps only the forwarding function, as
in the PE build.

macOS has no /proc/self/maps or MAP_FIXED_NOREPLACE, so the arena never came up and every guest allocation threw. Enumerate host regions with mach_vm_region and reserve free chunks with a fixed mach_vm_map, which fails instead of replacing. This skips dyld, the Rosetta runtime, and ranges the kernel never lets a process map (0x10_0000_0000-0x70_0000_0000). The POSIX commit/protection paths now build on macOS unchanged. Adds standalone guest_arena tests (x86_64 under Rosetta and arm64).
Every library under core/libs/prx links the libc and libkernel import
libraries, and every NID patch step depended on the unpatched libc.prx.
GNU ld 2.46 rewrites the import library on every link with new archive
timestamps (the member headers and the symbol map header), so the restat
on the link edge never pruned anything: one libc or libkernel .cpp edit
relinked all 124 libraries and re-patched all of them.
On MinGW the shared library link now writes the import library to
<implib>.new with SOURCE_DATE_EPOCH=0 (ld then writes zero member
timestamps), makes the symbol map deterministic with ranlib -D and copies
the result over the import library only when its bytes differ
(cmake -E copy_if_different). The link edge keeps restat, so a link that
keeps the exports leaves the import library untouched and prunes every
dependent link. The SOURCE_DATE_EPOCH also zeroes the export directory
TimeDateStamp of the DLL; the COFF header TimeDateStamp that the unwinder
keys on is unchanged.
The NID patch steps only use the names libc exports. nid_patcher
--write-export-list writes those names, normalized and sorted, to
libc.exports and leaves the file untouched when they did not change; the
patch steps read it with --preserve-export-list and depend on it instead
of libc.prx, on every platform. A patched library is byte-identical to
one patched against libc.prx.
Measured on Windows (GCC 15.2, -j 4, loaded machine) after touching
libc/src/Strings.cpp: with CMAKE_LINK_DEPENDS_NO_SHARED off, 124 links and
124 patches in 74.9 s before, 1 compile, 1 link, the export list and the
libc patch in 4.3 s after; with it on, 124 patches in 7.8 s before and
the same four steps in 5.3 s after. Touching libkernel/Time/Time.cpp
runs 123 links and 123 patches (89.1 s) before and one compile, link and
patch (3.4 s) after. Removing a libc export still relinks and re-patches
all 124 libraries.
nid_patcher_macho covers --write-export-list (sorted normalized names, no
rewrite when unchanged, rewrite when changed) and --preserve-export-list
(the same exports kept as with --preserve-exports; malformed lists and
two references refused). It fails on main, where the option is unknown.
