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. llvm-svn: 218179 2014-09-20 15:31:46 +08:00			`; RUN: llc -mtriple x86_64-pc-windows-msvc < %s \| FileCheck %s`

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. llvm-svn: 218268 2014-09-23 04:39:23 +08:00
