MC: Treat ReadOnlyWithRel and ReadOnlyWithRelLocal as ReadOnly for COFF A problem with our old behavior becomes observable under x86-64 COFF when we need a read-only GV which has an initializer which is referenced using a relocation: we would mark the section as writable. Marking the section as writable interferes with section merging. This fixes PR21009. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@218179 91177308-0d34-0410-b5e6-96231b3b80d8 2014-09-20 07:31:46 +00:00			`; RUN: llc -mtriple x86_64-pc-windows-msvc < %s \| FileCheck %s`

MC: Emit COFF section flags in the "proper" order COFF section flags are not idempotent: 'rd' will make a read-write section because 'd' implies write 'dr' will make a read-only section because 'r' disables write git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@228490 91177308-0d34-0410-b5e6-96231b3b80d8 2015-02-07 08:26:40 +00:00			`; CHECK: .section .CRT$XLB,"dr"`
MC: ReadOnlyWithRel section kinds should map to rdata in COFF Don't consider ReadOnlyWithRel as a writable section in COFF, they really belong in .rdata. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@218268 91177308-0d34-0410-b5e6-96231b3b80d8 2014-09-22 20:39:23 +00:00
