From b165f10c0ff5a92094ce24418bba8e3156fc76f4 Mon Sep 17 00:00:00 2001 From: Michael Tautschnig Date: Fri, 4 Jul 2025 19:35:32 +0000 Subject: [PATCH 1/2] Math library models: add missing *BSD variants, cleanup BSD systems appear to use `__` prefixed variants of several functions. Define these as needed. Also, avoid handling some GCC-style `__builtin_`-prefixed functions via models when others are done directly in the type checker: do all of them in the type checker. In addition to `__builtin_isfinite`, recognise its older glibc internal aliases `__builtin_finite`, `__builtin_finitef` and `__builtin_finitel` in the same isfinite_exprt branch of the type checker. Some glibc `` headers expose the legacy `finite()` API via these builtins, and without recognition CBMC would otherwise treat them as body-less functions returning nondet.

All other PR-triggered workflows are switched to workflow_dispatch only. pull-request-checks.yaml now has only two jobs: * debug-macos-15-intel: builds cbmc with Make, then collects the SDK deployment macros, the native byte representation of long double on real hardware, the preprocessed signbit/main.c, the cbmc trace and show-goto-functions output, plus a manual-union repro that prints the bytes CBMC stores for -1.0L. * debug-macos-14-arm: same diagnostic collection, control case where long double == double and the test passes. The full original workflow is preserved at .github/workflows/pull-request-checks.yaml.full and will be restored once the underlying long double bug is fixed.
