Nicolas GonzalezandClaude Opus 5.5 2c15fa59b4 fix(libc): keep write-watch fault-ahead inside the faulting page's 64 KiB block 
libSceAgcDriver decides per 64 KiB block whether a pending storage image
keeps the CPU's bytes. A window that ran into the next block marked it
CPU-written and dropped the GPU results there (agc_storage_write_back,
agc_idle_publish_wait, array layer and depth plane tests).

Nicolas GonzalezandClaude Opus 5.5 54080056ff perf(libc): unprotect the pages ahead of a sequential write fault on macOS 
A guest thread that writes a large watched range in order takes one
write-watch fault per page. Under Rosetta 2 each fault is a Mach
exception round trip. When the two pages before the faulting one were
written since the last collection, the handler now unprotects up to 32
pages from it that have the same protection and records them as
written. APS5_WRITE_WATCH_FAULT_AHEAD sets the count; 0 or 1 keeps one
page per fault.

pista baedb114f9 test(libs): build Emscripten adapters and check guest long doubles in CI 2026-10-30 10:50:57 +09:00
pista d64e85164b build(libs): let the system libraries compile with Emscripten 
Emscripten targets wasm64 without x86 assembly, Linux-only headers or the
x87 long double. These changes add __EMSCRIPTEN__ paths beside the host
ones; native builds compile the same code as before.

- libc: long doubles in guest varargs and scanf go through
  GuestLongDouble, a plain copy where long double is the x87 format;
  APS5_EXPORT emits no assembler alias; the guest arena is one aligned
  allocation that zeroes pages when they are committed again; getifaddrs
  keeps its link-level entries on Linux; /proc lookups and the host
  stderr duplicate are left out.
- libkernel: file-backed mmap, EVFILT_VNODE watches, getcontext and
  setcontext throw; getdents replaces the raw getdents64 syscall;
  getdtablesize takes the resource limit alone.
- VideoOut leaves SDL, the display window and the HDR probe out,
  Sysmodule asks libkernel for unwind information and Net includes
  sys/time.h.

JJenkxandClaude Opus 5.5 fb4fb58c87 fix(libc): report strerror_s violations as titles' libc.prx does 
The libc.prx that titles ship (PPSA07923, PPSA05916) rejects a
strerror_s capacity above SIZE_MAX >> 3, not SIZE_MAX >> 1, and calls
the constraint handler with "strerror_s: bad argument", EINVAL and a
null pointer for a null destination, a capacity of 0 or one past that
limit. main passed "strerror_s" and the destination, and wrote the
message for a capacity from 2^61 up.
