-fuse-init-array is now the CC1 default but TargetLoweringObjectFileELF::UseInitArray still defaults to false. The following two unknown OS target triples continue using .ctors/.dtors because InitializeELF is not called. clang -target i386 -c a.c clang -target x86_64 -c a.c This cleanup fixes this as a bonus. X86SpeculativeLoadHardeningPass::tracePredStateThroughCall can call MCContext::createTempSymbol before TargetLoweringObjectFileELF::Initialize(). We need to call TargetLoweringObjectFileELF::Initialize() ealier. test/CodeGen/X86/speculative-load-hardening-indirect.ll Differential Revision: https://reviews.llvm.org/D71360

; Check that our compiler never emits global constructors
|
|
; inside the .init_array section when building for a non supported target.
|
|
; Because of this, the test depends on UseInitArray behavior under NetBSD
|
|
; as found in Generic_ELF::addClangTargetOptions().
|
|
|
|
; This is to workaround a Visual Studio bug which causes field
|
|
; UseInitArray to be left uninitialized instead of being
|
|
; zero-initialized (as specified in [dcl.init]p7).
|
|
; This workaround consists in providing a user default constructor
|
|
; that explicitly initializes field UseInitArray.
