[pushed] Objective-C, Darwin : Update protocol metadata to current version.

Hi Later versions of the NeXT runtime protocol metadata contain additional fields. This patch adds these fields and populates a new list of method types. tested across the range of supported Darwin systems, and on x86_64-linux pushed to master, thanks Iain gcc/objc/ChangeLog: * objc-ne

[pushed] Ojective-C, Darwin : Adjust category superclass ref names (NFC).

Hi, Make the order of the class and superclass match the metadata order from clang. Makes it easier to compare produced meta- data between implementations. tested across the Darwin range and on x86_64-linux, pushed to master thanks Iain gcc/objc/ChangeLog: * objc-next-runtime-abi-02.c

[pushed] Objective-C++, Darwin : Make metadata 'extern "C"'.

Hi, For current system toolchains NeXT runtime metadata symbols are not mangled for Objective-C++ (i.e. they are considered to be 'extern "C"'). This change becomes essential when we start to emit metadata refs as hidden and weak which is required by later editions of the runtime and linkers. te

Fix handling of access ranges in ipa-modref

Hi, this patch fixes the range tracking in argument and re-enables it for clones (the bug that broke dealII and x264 benchmarks) It turned out that there was three problems 1) for SRA/ipa-cp clones we did not update summarries to represent new signature. This is now done in modref_transform.

[pushed] Objective-C, Darwin : Update message call codegen.

Hi Platform compilers based on LLVM do not use the objc_sendMsg_fixit and friends for newer editions of the OS (runtimes for Arm64 do not even have those entries). We need to arrange to allow for this codegen on modern Darwin. The _fixit versions are needed for some OS versions (at least, up to

[pushed] Darwin, Objective-C : Update meta-data linkage.

Hi Newer versions of ld64 require that some meta-data symbols are global, and that a larger set are linker-visible. tested across the Darwin range, and on x86_64-linux pushed to master thanks Iain gcc/ChangeLog: * config/darwin.c (darwin_globalize_label): Add protocol meta-data

[pushed] Darwin, Objective-C : Adjust objective-c symbol linkage with version.

Hi Earlier linkers cannot handle publicly-visible (or linker-visible) metadata, so we need to make the output of these conditional on version. tested across the Darwin range, and on x86_64-linux pushed to master thanks Iain gcc/ChangeLog: * config/darwin.c (darwin_globalize_label): Make

[pushed] testsuite, Objective-C : Compatibility fixes.

Hi Changes to deal with warnings and/or errors seen when compiling the tests with clang (allowing us to compare a sub-set of the tests between implementations). tested across the Darwin range, and on x86_64-linux pushed to master thanks Iain gcc/testsuite/ChangeLog: * objc-obj-c++-share

[pushed] testsuite, Objective-C : Update a test for newer OS versions.

Hi Objective-C GC is not available for any recent Darwin version, nor is it available for the upcoming release of Darwin20. This just updates the skip conditions for the test. tested across the Darwin range, and on x86_64-linux pushed to master thanks Iain gcc/testsuite/ChangeLog: * ob

[pushed] testsuite, Objective-C : Adjust gnu-api tests for Darwin.

Hi (Darwin tests both the GNU and NeXT runtimes) The GNU v2 API matches the next v2 API in most respects. However, some of the tests depend on access to items that the later NeXT headers consider to be 'internal implementation details' and are not exposed (we arrange that with a DEFINE). One te

[pushed] testsuite, Objective-C : Add initialize method to root class.

Hi Older versions of the runtime don't like it when the root class has a missing initialize method. They try to forward to an non- existent super class resulting in a crash. TODO: maybe we can diagnose this. tested across the Darwin range, and on x86_64-linux pushed to master thanks Iain gcc/t

[pushed] testsuite, Objective-C : Update forward-1.m.

Hi Newer versions of the runtime / NSObject don't respond to forward:. This uses the replacement. tested across the Darwin range, and on x86_64-linux pushed to master thanks Iain gcc/testsuite/ChangeLog: * objc.dg/torture/forward-1.m: Implement forwarding using the native NeXT (

[pushed] testsuite, Objective-C : Fix call-super-2.m for newer NeXT headers.

Hi, We were using a callout to runtime.h which, eventually brings in the system runtime.h. One newer versions of the Darwin/NeXT headers this declares the objc_getClass() function as returning Class, rather than the internal representation of that. This breaks a fragile assumption in objc-act th

[pushed] testsuite, Objective-C : Fix two plugin diagnostics tests for Darwin.

Hi The @selector and @protocol keywords produce a var decl without useful location information. The current diagnostics plugin does not look at VAR_DECLs (and it would not be helpful if it did in this case, since a single decl is shared across all the users). However, we can, in this case, make e

[pushed] testsuite, Objective-c++ : Fix GNU API tests to work with NeXT where possible.

Hi (Darwin tests both GNU and NeXT runtimes). The version 2 GNU Objective C API is mostly compatible with the NeXT one. However, there are a few testsuite tweaks needed (and one test fails for NeXT without considerable increase in complexity). tested across the Darwin range, and on x86_64-linux

[pushed] testsuite, objective-c++ : GC is not available from Darwin16.

[pushed] testsuite, Objective-c++ : Add a dummy retain/release to testuite object.

Hi On newer systems, the throw/catch process sends retain and release messages to thrown objects. While these are not needed in the testsuite cases, they cause the tests to fail because the selector is not handled. Add dummy methods to the testsuite object. tested across the Darwin range, and on

[pusshed] testsuite, Objective-c++ : Update diagnostic plugin test.

Hi The @selector() and @protocol() operators produce var decls these do not work with the example plugin. Unfortunately, unlike the ObjC front end, it is not so easy to construct a substitute expression that works reliably. Where it does not work we xfail for now. tested across the Darwin range

[pushed] Objective-C++ : Fix bitfield ivars regression.

Hi This fixes a regression present from 8.x; It used to be OK to test for a DECL_INITIAL value to flag that an ivar was a bitfield (the initial value was the width). This still works on C / Objective-C, but no longer on C++. Replace the test with DECL_C_BIT_FIELD() which is set for both C and C

Hi This corrects a typo in the recipe for the special type alignment rules that are used for 32bit powerpc Darwin platforms. The regression is present in all open branches (but luckily not on 7.5). I plan to fix it on the branches too. tested across the Darwin range, and on x86_64-linux pushed

import elementary functions as intrinsics

Importing them as intrinsics enables GCC to treat them as builtins whose behavior is known by GCC. Specifically, if they aren't intrinsics, calls to Sin and Cos won't be combined into sincos. We still need to make Sin and Cos wrappers inline in user-exposed interfaces to get users the benefit o
