>From c39f2eeb4cdd9eccb0a31f3d95e078f2c7205c8c Mon Sep 17 00:00:00 2001 From: Prajwal Nadig <[email protected]> Date: Fri, 15 May 2026 13:59:24 +0100 Subject: [PATCH] [ExtractAPI] Add support for anyAppleOS 6c8940ccad31457aadb48c6f2bce139b1c5dda01 introduced support for anyAppleOS, which can be used to indicate availability for all Apple platforms in a single availability attribute. 3089120f0cd2fe78911d1bc9703764a07fa7eb32 updated it to preserve the original attribute info and store the inferred platform-specific attribute in a separate field which, if present, is returned by `getEffectiveAttr()`. With these changes, ExtractAPI now reports these availabilities verbatim for an "anyAppleOS" platform as the availability info for Decls directly uses the availability attribute without fetching the effective attribute. The expected output would be the target platform for which the symbol graph is being built. This patch updates the availability collection logic to use `getEffectiveAttr()` and include the target platform instead of "anyAppleOS" for symbol availabilities in symbol graphs. rdar://174558184 --- clang/lib/AST/Availability.cpp | 6 +- .../test/ExtractAPI/availability-anyappleos.c | 162 ++++++++++++++++++ 2 files changed, 166 insertions(+), 2 deletions(-) create mode 100644 clang/test/ExtractAPI/availability-anyappleos.c diff --git a/clang/lib/AST/Availability.cpp b/clang/lib/AST/Availability.cpp index cf040fc727d11..cd9152745826f 100644 --- a/clang/lib/AST/Availability.cpp +++ b/clang/lib/AST/Availability.cpp @@ -48,9 +48,11 @@ static void createInfoForDecl(const clang::Decl *Decl, // Collect availability attributes from all redeclarations. for (const auto *RD : Decl->redecls()) { for (const auto *A : RD->specific_attrs<clang::AvailabilityAttr>()) { + const auto *Eff = A->getEffectiveAttr(); Availabilities.insert(clang::AvailabilityInfo( - A->getPlatform()->getName(), A->getIntroduced(), A->getDeprecated(), - A->getObsoleted(), A->getUnavailable(), false, false)); + Eff->getPlatform()->getName(), Eff->getIntroduced(), + Eff->getDeprecated(), Eff->getObsoleted(), Eff->getUnavailable(), + false, false)); } if (const auto *A = RD->getAttr<clang::UnavailableAttr>()) diff --git a/clang/test/ExtractAPI/availability-anyappleos.c b/clang/test/ExtractAPI/availability-anyappleos.c new file mode 100644 index 0000000000000..ebac953147477 --- /dev/null +++ b/clang/test/ExtractAPI/availability-anyappleos.c @@ -0,0 +1,162 @@ +// RUN: rm -rf %t + +/* + * This test file looks slightly different from the other ones since the + * `anyAppleOS` availability attribute needs to be tested for multiple + * target platforms.
