From d6b43a317e71246380db55a50b799b062b53cdce Mon Sep 17 00:00:00 2001 From: Rafael Espindola Date: Tue, 19 Jun 2012 00:48:28 +0000 Subject: Move the support for using .init_array from ARM to the generic TargetLoweringObjectFileELF. Use this to support it on X86. Unlike ARM, on X86 it is not easy to find out if .init_array should be used or not, so the decision is made via TargetOptions and defaults to off. Add a command line option to llc that enables it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158692 91177308-0d34-0410-b5e6-96231b3b80d8 --- include/llvm/Target/TargetOptions.h | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) (limited to 'include/llvm/Target/TargetOptions.h') diff --git a/include/llvm/Target/TargetOptions.h b/include/llvm/Target/TargetOptions.h index 12a2757..bc60673 100644 --- a/include/llvm/Target/TargetOptions.h +++ b/include/llvm/Target/TargetOptions.h @@ -43,7 +43,7 @@ namespace llvm { StackAlignmentOverride(0), RealignStack(true), DisableJumpTables(false), EnableFastISel(false), PositionIndependentExecutable(false), EnableSegmentedStacks(false), - TrapFuncName(""), FloatABIType(FloatABI::Default) + UseInitArray(false), TrapFuncName(""), FloatABIType(FloatABI::Default) {} /// PrintMachineCode - This flag is enabled when the -print-machineinstrs @@ -172,6 +172,10 @@ namespace llvm { unsigned EnableSegmentedStacks : 1; + /// UseInitArray - Use .init_array instead of .ctors for static + /// constructors. + unsigned UseInitArray : 1; + /// getTrapFunctionName - If this returns a non-empty string, this means /// isel should lower Intrinsic::trap to a call to the specified function /// name instead of an ISD::TRAP node. -- cgit v1.1
