From 6305f8a3517f5a702b691f81d669145263f82fa2 Mon Sep 17 00:00:00 2001 From: Yaxun Liu Date: Thu, 18 Aug 2016 19:34:04 +0000 Subject: [OpenCL] AMDGCN: Fix size_t type Pointers of certain GPUs in AMDGCN target in private address space is 32 bit but pointers in other address spaces are 64 bit. size_t type should be defined as 64 bit for these GPUs so that it could hold pointers in all address spaces. Also fixed issues in pointer arithmetic codegen by using pointer specific intptr type.
