What

hypotf rounded the host's double hypot to float. That is almost always the correctly rounded result, but the titles' copy is not correctly rounded, so the two differ on 982,314 of 16 million random pairs. For example, hypotf(0xc3a8012e, 0x47264372) is 0x472644c5 on the console and 0x472644c6 here.

The titles' copy (NID iz2shAGFIxc) is FreeBSD msun's e_hypotf.c, computed in float. hypotf now computes it:

• the ordering by bits;
• the a + b return when the ratio exceeds 2^30;
• the infinity and NaN handling, where an infinity wins over a NaN and a NaN result keeps the argument order, with its sign cleared;
• the 2^-68, 2^68 and 2^126 scaling;
• the two sqrtf forms with the operands split at their low 12 bits.

main's existing hypotf tests still pass. They include the invalid exception for a signalling NaN next to an infinity, which x + 0.0F raises as in msun. hypot3f calls this hypotf, and its existing tests still pass too.

errno: neither msun nor the titles' copy sets it, even when a finite pair overflows to infinity, and this port sets none either.

Tested

Current-main integration — 2026-11-03. Head 83dcad0259ea65fc6ffbd16ed56af75f5f003ee5 includes main 4f41f4c375f5abb487dbd184fbc150f31994d762 and retains the prior public history and attribution/licence notices. Main’s newer math implementations and fixtures remain alongside this topic.

Linux x86-64 Release, GCC 16.2.1, Ninja, BUILD_TESTING=ON: rebuilt actual libc and math executables. guest_math, guest_math_exact, and guest_dinkumware_internals each pass 3/3 (9 passes, zero skips); public_headers and conventions pass. The same three groups pass 3/3 plus headers on pinned main. All 34 recursive dependency trees and 31,551 tracked blobs verify with zero errors; the update=none QuickJS test262 corpus is excluded from these library inputs. Whitespace check passes.

Source/parent/gitlink proofs, exact library/test hashes, raw logs/JUnit, and head-leased push receipts: qualification archive, SHA-256 e6a50522bc28e30871fdc2c12a88d2537515914239e8166f6237f48895126a06 (download verified). Older platform/reference reports retain their original pins; no new Windows/macOS, SDK-module, console, title/GPU or performance claim. AI-assisted: yes (Codex).

Earlier dated qualifications below retain their recorded source/platform pins.

Current-main refresh — 2026-11-02. Published head 04983c615f878dc138be93f879e7e75106626283 includes pinned main a4eca2a056bf3bbbec98ab42e9d28163e4ea9cb8. The hypotf production body and CheckHypotfConsoleBits fixture remain unchanged. Main’s log10/log2/atan functions and test calls are retained. The refreshed topic is linear on pinned main with original authorship.

Rebuilt actual libc/Ampr and selected tests from the final input tree. guest_math, guest_math_exact, guest_dinkumware_internals each pass three consecutive runs: 9 runtime passes, zero skips, plus public_headers. Conventions and whitespace pass. Source/input manifests, exact dependencies, library/test hashes, logs/JUnit and head-leased push receipts are attached. The same pinned main passes 18 selected groups three times (54 runtime passes) plus headers. All 34 recursive dependency trees/31,551 tracked blobs verify with zero errors; QuickJS’s update=none test262 corpus is explicitly excluded because it is not a library build input.

Linux-7.2.11-arch1-1-x86_64-with-glibc2.44, Ryzen 9 7950X, GCC 16.2.1, Ninja Release, BUILD_TESTING=ON. Focused Linux CPU qualification only.

Rebased without merge commits onto main 73f4f7e06e4f210a8c6570e335fd654dc0a86134. Tested exact head 33186d0401fffd98cbc1d1c552ff6f6b3f15767d on Linux x86-64 (AMD Ryzen 9 7950X, GCC 16.2.1, Ninja Release, BUILD_TESTING=ON, bundled dependencies).

Rebuilt libc, guest_math_tests, guest_math_exact_tests and guest_dinkumware_internals_tests. guest_math, guest_math_exact, guest_dinkumware_internals and public_headers each pass three consecutive times on both pinned main and this exact head: 12 passes per side, zero skips. Conventions and whitespace checks pass. GitHub current-main integration is now backed by these local tests; the latest fetched main also has a clean merge preview.

Original authored executable code and tests are preserved. The exp parent retains its FreeBSD notice; trailing whitespace was removed from three copyright-notice lines. No new Windows, macOS, bundled-SDK/console reference, GPU/title, performance or full-suite execution is claimed. Earlier reference comparisons retain their original source pins.

Checklist

• Based on current main; no other open PR implements the same functions. fix(libc): compute erf and erfc with FreeBSD msun's algorithm, as titles' libc.prx does #10321 and fix(libc): compute hypot with FreeBSD msun's algorithm, as titles' libc.prx does #10325 add their test functions and debt entries at the same places in core/libs/tests/GuestMath.cpp and docs/dev/debt/libc.md, so whichever of these PRs lands later needs those lines merged
• One topic per PR; follow-ups go in a new PR
• No comments in code except technical debt
• Unimplemented paths throw (NotImplemented_nid_no_patch); silent stubs are listed under Silent stubs in their library's technical debt file
• No notes, investigation .md files or images added to the repository (attach them to this PR)
• New third-party code is a submodule built from source: none; the msun function is rewritten, as fix(libc): compute acosf with FreeBSD msun's algorithm, as the console's libc.prx does #9668, feat(libc): implement atanhf #5036 and the sinhf entry did
• Generic behaviour, not specific to one title
• Depends on: none
• Fixes: none
• Unblocks: none
• GPUs tested: n/a
• AI-assisted: yes

Linux run at this PR's exact head 7b2f8875c2 (7b2f8875c2cf35ffe6740d1524c5cdb5370933f0), not merged onto anything else; its base on main is 4883171f9f.

Arch Linux, kernel 7.2.9, Ryzen 9 7950X, g++ (GCC) 16.2.1 20260810, glibc 2.44, x86-64. Release, BUILD_TESTING=ON.

• guest_math: passed in each of 3 runs, exit code 0 each time, with no failed, skipped or not-run tests.

This is the focused test only; no title, console or floating-point exception flags were checked.

AI-assisted: yes (Claude Code).

[JJenkx]

Refreshed onto main379b1dca32 as5de85a223d54, one topic commit/no merges. Only an additive debt conflict needed resolving; main coshf and this hypotf entry are both retained. The hypotf implementation body is unchanged from7b2f8875c2. Fresh Linux libc build and guest_math/guest_dinkumware_internals each pass3/3; diff and conventions pass. New Linux build/test logs and rebase review are linked in the description. Earlier Windows/title-library sampling retains its original scope; it was not rerun for this rebase.

[harisibrar1]

Checked against main 7966e59 and FreeBSD msun e_hypotf.c at release/9.0.0, 10.0.0, 11.4.0, 12.0.0 and 13.0.0:

• Thanks for this. The body matches release/11.4.0 line for line. 9.0.0 and 10.0.0 behave the same, since they only write the final scale as 0x3f800000+(k<<23), which equals (127+k)<<23 for every reachable k, so the 11.4.0 link is the right one. From 12.0 on, the Inf/NaN line is fabsl(x+0.0L)-fabsf(y+0), so citing 11.4 rather than a newer release makes sense.
• Emulating the algorithm in float reproduced all 12 non-special console vectors in CheckHypotfConsoleBits in both argument orders. The old double-hypot path differs on 6 of them, including (0xc3a8012e, 0x47264372).
• Optional: the only two-NaN case checks (0xffc00002, 0x7fc00001), where I'd expect 11.4 and 12.0+ to agree. I couldn't run it, but reading the 12.0 fabsl line suggests the reversed pair (0x7fc00001, 0xffc00002) gives payload 1 with this code and payload 2 with 12.0+. If your title comparison has that pair's console bits, adding it would pin the version in the test.
• Merges cleanly onto current main, and main's hypotf is still the double-hypot cast.

Reviewed with AI assistance (Claude Code); the checks above were run locally on my machine.

Rebased onto main 1e20650e84 as a46d0990f256e05a4016ba16dc5805fcce840d9c, preserving the merged expm1 entries and this topic. Both Linux math suites pass 3/3; fresh module comparisons reproduce the previous observations. The suggested reversed quiet-NaN case is now in the regression, after checking both bundled copies. Current-head evidence. Windows remains untested for this refresh.

[ycbuzi]

Windows run of a46d099 merged onto main fa515de (dbfb289b9e, clean), since Windows was not run on this head. Windows 11 Home 10.0.26200, MinGW-w64 GCC 15.2.0 (ucrt-posix-seh r7), Release, BUILD_TESTING=ON.

Built libc, guest_math_tests and guest_dinkumware_internals_tests with no errors or warnings. ctest --repeat until-fail:2 on guest_math and guest_dinkumware_internals: both pass on both repeats. Negative control: with src/Math.cpp taken from main and the rest of this head, guest_math aborts (exit code 0xc0000409) and guest_dinkumware_internals still passes. Not run: a title.

[MarcZX10]

The prior review and follow-up provide useful exact-head evidence, including the reversed quiet-NaN case and repeated guest_math/guest_dinkumware_internals runs on Linux and Windows. After refreshing upstream/main, however, this branch's merge base is 1e20650e8458, with 6,822 current-main commits since it. CONTRIBUTING.md asks contributors to keep branches up to date with main, and current hosted product jobs are skipped. Please update to current main and rerun guest_math and guest_dinkumware_internals on the resulting tree. The math implementation looks well supported on the old base; I will revisit approval when current-base integration is validated.

[JJenkx]

Refreshed onto current main as requested in review.

Current-head Linux refresh (2026-10-25): 60f77dfeda7df3b5e92d1f733e97036641aa496d, one topic commit directly on main e7e3e9c1984c293f06bff08428b8c89b7b932ac2, with no merge commits. Depends on remains none. The complete production function is byte-identical to the previous public head, and all original regression cases, including the reversed quiet-NaN check, are retained. Main's merged exp2f/expm1, exact-rounding tests and current public declarations are preserved.

• Fresh focused libc, guest_math_tests, guest_math_exact_tests and guest_dinkumware_internals_tests builds pass.
• guest_math, guest_math_exact, guest_dinkumware_internals and public_headers each pass three consecutive runs, with no skips.
• Negative control restores only main's production Math.cpp while keeping the final fixtures: guest_math aborts and guest_dinkumware_internals passes. Restore the final source, rebuild to the byte-identical libc.prx, then both suites pass three more runs each.
• Conventions and whitespace checks pass, and the branch merges cleanly with current main.

The earlier Windows/module comparisons below are historical; no fresh Windows, title or console run is claimed. Our Windows host remains explicitly user-paused. Download exact-head source pins, logs, JUnit, negative and restoration results; SHA-256 91a0ee7bc1b8ccfe356dee6cfcbe1dc7b96bf13d06a8ec05f7e4bfb06fd5ec74.

Linux check of the current head 71ab8de49b, a merge of main 0540ef0ef2 into this branch (no source change beyond the merge). Against that main the PR still changes only Math.cpp, GuestMath.cpp and the libc debt entry.

Arch Linux 7.2.11, Ryzen 9 7950X, GCC 16.2.1, Ninja Release, BUILD_TESTING=ON, fresh build of the merged tree: ctest -R "[Mm]ath|relocations" passes 13/13.

The earlier macOS relinker failure (guest_none_relocations, timeout at 20 s, run 41887932424) did not recur: all checks pass on this head.

Dismissed as met: the head now merges current main (71ab8de with main 0540ef0); the author posted a fresh Linux build and ctest on it, Windows 3/3 on 9cfddbd merged onto main b611e63, and the AMD CI bot passed on 71ab8de (2026-11-05).

[JJenkx]

Refreshed onto main e772fb25cc (merge dd513a2ba2). #10325 landed hypot next to this PR's hypotf, so all three files conflicted.

Resolution: I kept main's versions and re-applied only this PR's changes:

• the msun hypotf port in place of main's one-line std::hypot cast;
• its checks and call;
• its debt entry.

#include <utility>, which this PR added, is already in main, so the merge is one line shorter than the PR's own diff; otherwise it differs from main in exactly this PR's three files.

Windows, WinLibs GCC 15.2 UCRT, Release:

• Math tests: guest_math, guest_math_exact, guest_math_elementary, guest_dinkumware_internals and public_headers pass in 3 of 3 runs.
• Negative control: with main's Math.cpp, guest_math fails in CheckHypotfConsoleBits.
• Conventions: tools/check_conventions.py passes.

AI-assisted: yes.

[JJenkx]

Linux check of exact head dd513a2ba2. Arch Linux 7.2.11, GCC 16.2.1, Release, BUILD_TESTING=ON.

guest_math, guest_math_exact, guest_math_elementary, guest_dinkumware_internals and public_headers pass in 3 of 3 runs each (ctest --repeat until-fail:3), none skipped. These are the tests the Windows refresh ran.

agc_driver_float16_unused_nan_payloads: skipped, the device has no native f16 conversions with RTE rounding and kept f16 denormals
agc_driver_gcn_display_present: skipped, no display: Vulkan support is either not configured in SDL or not available in current SDL video driver (offscreen) or platform
agc_driver_image_table_vouched_lookups: skipped, the device reports 4 of 4 host-imported pages written after a GPU read, so a watched imported table cannot be vouched for
agc_driver_linear_target_direct_write_completion: skipped, the device does not keep host imports write-watched, so no completion stamp over the target is tracked
agc_driver_ngg_vertex_wave_reduction: skipped, s3 describes a 32-lane wave only on 32-lane subgroups, and the device has 64 lanes

Hi @JJenkx, I merged main (54d4201dc5, merge 437a420e12) into this branch now that #10245 has landed. The conflicts were only additions on both sides: GuestMath.cpp keeps your CheckHypotfConsoleBits next to main's new CheckTrigConsoleBits, and libc.md keeps your hypotf line next to the new log and atanh lines. No other changes.

Linux check of the merge head (Release, BUILD_TESTING=ON): guest_math, guest_math_exact, guest_math_elementary and guest_dinkumware_internals pass.
