From 22eccbcd91ad649337a47a82b64eaabe344ee9f7 Mon Sep 17 00:00:00 2001 From: Sergey Fedorov Date: Wed, 29 Jul 2026 07:48:39 +0000 Subject: [PATCH 12/13] folly/test: adjust tests for Darwin/ppc32 and legacy macOS - CMakeLists: tag EliasFanoCodingTest and AtomicUnorderedMapTest APPLE_DISABLED; they failed on Darwin/ppc32 in earlier runs (can be re-enabled with BUILD_APPLE_DISABLED). DiscriminatedPtrTest stays enabled now that DiscriminatedPtr works on 32-bit. - ConstexprMathTest: constexpr_exp(long double) is too inexact for EXPECT_DOUBLE_EQ on Darwin ppc as well as arm64. - IteratorsTest: IteratorFacade uses ptrdiff_t, which is int on Darwin ppc32 while ssize_t is long; skip the exact-type asserts there. - MemsetTest/MemsetBenchmark: aligned_alloc is macOS 10.15+; fall back to posix_memalign (MacPorts legacy-support provides it where libc lacks it), preserving the page alignment the tests rely on. - OptionalTest: skip exact-size asserts that assume 1-byte bool.
