Yaxun Liu	0124b5484c	[AMDGPU] Change constant addr space to 4 ... Differential Revision: https://reviews.llvm.org/D43170 llvm-svn: 325030	2018-02-13 18:00:25 +00:00
Yaxun Liu	dcb6067d9f	[AMDGPU] Update test nullptr.ll to use amdgiz environment ... This test needs to be manually updated since it is difficult to do it with script. Addr space 6 to 23 are only used by r600, therefore only check them for r600. Differential Revision: https://reviews.llvm.org/D40117 llvm-svn: 319092	2017-11-27 20:48:21 +00:00
Matt Arsenault	971c85ebb4	AMDGPU: Treat 0 as private null pointer in addrspacecast lowering ... llvm-svn: 297658	2017-03-13 19:47:31 +00:00
Yaxun Liu	8f844f3960	[AMDGPU] Lower null pointers in static variable initializer ... For amdgcn target Clang generates addrspacecast to represent null pointers in private and local address spaces. In LLVM codegen, the static variable initializer is lowered by virtual function AsmPrinter::lowerConstant which is target generic. Since addrspacecast is target specific, AsmPrinter::lowerConst This patch overrides AsmPrinter::lowerConstant with AMDGPUAsmPrinter::lowerConstant, which is able to lower the target-specific addrspacecast in the null pointer representation so that -1 is co Differential Revision: https://reviews.llvm.org/D29284 llvm-svn: 294265	2017-02-07 00:43:21 +00:00
