2013-03-30Use kernel metadata to differentiate between kernel and deviceJustin Holewinski
functions for the NVPTX target. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@178418 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-28CUDA: give static storage class to __shared__ and __constant__Peter Collingbourne
variables without a storage class within a function, to implement CUDA B.2.5: "__shared__ and __constant__ variables have implied static storage [duration]." git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162788 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-28CUDA: give correct address space to globals declared in functionsPeter Collingbourne
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162787 91177308-0d34-0410-b5e6-96231b3b80d8

2012-05-20CUDA: add CodeGen support for global variable address spaces.Peter Collingbourne
Because in CUDA types do not have associated address spaces, globals are declared in their "native" address space, and accessed by bitcasting the pointer to address space 0. This relies on address space 0 being a unified address space. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@157167 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-06CUDA: IR generation support for device stubsPeter Collingbourne
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@141304 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-06CUDA: add -fcuda-is-device flagPeter Collingbourne
This frontend-only flag is used by the IR generator to determine whether to filter CUDA declarations for the host or for the device. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@141301 91177308-0d34-0410-b5e6-96231b3b80d8
