What

Exports std::__sce_v2::_Syserror_map_search(int) (a9DvgsV9dWw) and makes the versioned std::__sce_v2::_Syserror_map(int) use the same table.

The console libc.prx in PPSA02530 and PPSA28416 exports _Syserror_map_search at 0xce8b0 / 0xcfb50 (41 bytes). It walks 79 16-byte records, compares the int at offset 0 and returns the pointer at offset 8; the fallback is null. The record pointers are RELA relocations, so resolving them from the bundled module gives the 79 strings, including entry 0 {0, "success"} and the Sony codes 107, 108, 1040, 1050, 1051 and 1074. Codes 35 and 45 occur twice and the first record wins.

The versioned _Syserror_map (4ITMYcbipA0, 0xce870, 57 bytes) is the same loop with "unknown error" as the fallback. Before this change AnyPS5 used the shared FreeBSD list, which has no Sony codes and maps 95/96, which are not in the console's versioned table. Both versioned functions now share the console table; the unversioned _Syserror_map is unchanged.

Tested

Linux x86-64, GCC 16.2.1, Release, BUILD_TESTING=ON.

• guest_sce_v2_exceptions and guest_generic_category pass.
• python3 tools/check_conventions.py --base origin/main and git diff --check pass.
• Not tested with a title: PPSA28416 stops at sceNpGetSandboxInfo before these imports are reached. No Windows product run; the hosted product jobs are skipped by path policy.

[MarcZX10]

I reviewed the table and both callers against the PR description. The separate search function returns null when no entry matches, while the versioned mapper keeps its unknown error fallback; the tests cover the Sony-specific values, duplicate-code first-match behavior, and the distinction from the unversioned FreeBSD map. The symbol spelling also hashes to the stated NID a9DvgsV9dWw with the repository tool.

One repository rule remains: the head is based on 2db37cf1de, while current main is 035ac96edd (17 commits ahead). The intervening commits do not touch these implementation/test paths, and the merge preview is clean, but CONTRIBUTING.md says to keep branches up to date. Please sync to current main and let conventions rerun. I’ll recheck the pending hosted matrix after it finishes. The Linux focused-test results in the PR description are author-reported; I did not independently run them.

[MarcZX10]

I completed the source review and the implementation matches the supplied binary analysis: _Syserror_map_search returns null for misses, while versioned _Syserror_map preserves the unknown error fallback; selected tests cover Sony codes, duplicate-code order and the unchanged unversioned map. The stated symbol NID checks with tools/nid_names.py. I found no source defect in this patch.

The remaining merge blocker is the repository branch rule: this head is based on 2db37cf1de, while current main is 035ac96edd (17 commits ahead). The intervening commits do not touch the changed implementation or test files and the merge preview is clean. Please sync to current main and rerun conventions. Eligibility, conventions, intake, labels, report, Ubuntu relinker/ASan/register-context and the Windows relinker now pass; macOS relinker, register-context and write-watch jobs remain pending. The Linux focused test result in the PR description is author-reported, not independently run here.

[edubox]

Rebased onto current main 035ac96edd; the change itself is unchanged. guest_sce_v2_exceptions and guest_generic_category pass on the rebased head 16ca7b8a3d, and check_conventions.py and git diff --check are clean. Could you recheck the pending hosted matrix?

[MarcZX10]

Rechecked the fresh run 40327664941 at head 16ca7b8a3d. Eligibility, conventions, intake, labels, report, Ubuntu relinker, Ubuntu Debug/Release register-context and ASan pass. The Windows relinker is still running; macOS relinker, macOS register-context and write-watch jobs are queued. Linux/Windows product checks are skipped by path policy. I’ll check back after the remaining matrix finishes before updating the review state.

[MarcZX10]

I manually checked the overlap bot’s two Api.hpp warnings against the current heads: #7851 changes _Atomic_assert near line 104, #9772 adds _Stopfx declarations near line 975, and this PR adds _Syserror_map_search near line 1408. They touch distinct declarations and have no duplicate symbol or overlapping hunk, so I found no dependency. The macOS jobs on run 40327664941 remain queued; I’ll wait for those before changing the review state.

A native Windows run of 16ca7b8a3d: Windows 11 Home 10.0.26200, WinLibs GCC 15.2.0 r7 (MinGW-w64 UCRT), Release, merged onto main e38fcb00dc with no conflicts. Plain ctest --repeat until-fail:3.

• guest_sce_v2_exceptions passes, 3 of 3. The build has no warnings.
• No negative control: with main's libc/include/Api.hpp and StandardExceptions.cpp, the test doesn't build ('_ZNSt8__sce_v220_Syserror_map_searchEi_nid_postfix' was not declared in this scope at GuestSceV2Exceptions.cpp:175).

[edubox]

Rebased onto current main (518d36eaec); head is now 362482dbd0. Rebuilt guest_sce_v2_exceptions on the rebased head: passes. check_conventions.py --base origin/main: all checks passed.

[edubox]

Rebased onto current main (88795ed448); head is now 89e17c62a5. The change itself is unchanged. Rebuilt and ran guest_sce_v2_exceptions and guest_generic_category on the rebased head: both pass. check_conventions.py --base origin/main and git diff --check are clean. Could you re-check the exact head?

[edubox]

Rebased again onto current main (85071975fb); head is now 201ad43d93. No code changes. guest_sce_v2_exceptions and guest_generic_category pass; conventions/diff-check clean. Could you re-check the exact head?

[edubox]

Rebased automatically onto current main (fc2594c7ac); head is now 94e7c49bbc. Focused tests pass; check_conventions.py --base origin/main and git diff --check are clean.

[edubox]

Rebased onto main 74acfad65b; the conflict in StandardExceptions.cpp was main's future-error/category block overlapping the tail of the file. Kept both changes: the future-error exports and the new _Syserror_map_search next to the versioned _Syserror_map. Head is now dd732db60a.

Local verification:

• guest_sce_v2_exceptions and guest_generic_category pass.
• python3 tools/check_conventions.py --base origin/main and git diff --check pass.
• PR is now MERGEABLE; eligibility should rerun on the new head.

Synced to current main (rebase onto 0a570f617d, clean) and pushed 826241081d.

• guest_sce_v2_exceptions and guest_generic_category pass locally (Linux x86-64, GCC 16.2.1, Release).
• python3 tools/check_conventions.py --base origin/main and git diff --check pass.
• The previous Windows relinker failure was check_compile_modes_test_library_directory_values_can_look_like_modes (Timeout), an unrelated relinker test timeout; the changed paths are libc-only. The rebuilt matrix on the new head will confirm.

No source changes were needed; the patch still matches the console analysis.

Follow-up: main advanced to 2e85f47aef (the two new commits touch only ElfTypes.hpp). Rebased again onto it and pushed the final head 20a525a914; guest_sce_v2_exceptions and guest_generic_category still pass, and check_conventions.py --base origin/main is clean. The hosted matrix is rerunning on this head.

[MarcZX10]

The prior source review found the new versioned error-map search behavior consistent with the referenced runtime and its tests cover the Sony codes, duplicate-code ordering, and unchanged unversioned map. The author has refreshed the branch through current main and reports focused tests, conventions and diff checks passing. I did not run them locally. No new source concern is visible in this rebase.

[MarcZX10]

Re-checked — looks good

I reviewed head 9f687728a12434730faa1fa95496c8f66a11a441 against recorded base 0839e8f3442331a951efe82b5ba700007bc36539; the three-file diff remains scoped to the versioned error-map export/table and focused tests. The hosted Windows product check passes and Linux was skipped; I ran no local C++ tests. I found no blocking issue.

[edubox]

Watchdog status on 9f687728a1: the only failing checks are the two write-watch jobs, and they fail while configuring main, not in this patch. core/libs/tests/write_watch/CMakeLists.txt on current main (98ddd9c179) registers write_watch_execute-fault and write_watch_read-fault twice (the foreach(mode execute-fault read-fault) block added by #12117 and again by #12435), so CMake aborts with add_test given test NAME ... which already exists. This PR does not touch that file; #13220 removes the duplicate and its write-watch jobs pass. The added test lines and implementation are unchanged from the head where guest_sce_v2_exceptions passed, and python3 tools/check_conventions.py --base origin/main is clean. Branch left unchanged; no rebase or push.

AI-assisted: yes

[edubox]

Status check on exact head 9f687728a1 (no push, the PR is approved and is not rebased per policy):

• Focused tests pass on this machine: guest_sce_v2_exceptions_tests and guest_generic_category_tests.
• python3 tools/check_conventions.py --base origin/main and git diff --check origin/main...HEAD are clean.
• The two failing write-watch (macos-15 / macos-15-intel) jobs are not caused by this change: core/libs/tests/write_watch/CMakeLists.txt on main registers the foreach(mode execute-fault read-fault) block twice (lines 36-44; introduced by fix(libc): forward non-write faults from watched macOS pages #12117 and fix(libc): forward writes to truncated macOS mappings #12435), so the macOS write watch tests are defined twice on every PR. test(libc): register the macOS write watch fault tests once #13220 registers them once and should clear these jobs.

Nothing to change in this branch for that failure; leaving the approved head untouched.

AI-assisted: yes (Claude Code).

[edubox]

The two write-watch failures are not from this PR. Both jobs fail while configuring core/libs/tests/write_watch on main:

CMake Error at core/libs/tests/write_watch/CMakeLists.txt:42 (add_test):
  add_test given test NAME "write_watch_execute-fault" which already exists
  in this directory.

and the same for write_watch_read-fault: main registers both tests twice. #13220 removes the duplicate registration. This PR touches only core/libs/prx/libc/include/Api.hpp, StandardExceptions.cpp and GuestSceV2Exceptions.cpp.

Verified here at head 9f687728a1: guest_sce_v2_exceptions and guest_generic_category pass, and python3 tools/check_conventions.py --base origin/main passes. No push: the head is already approved and the remaining red checks are the open #13220.
