hipclang-3.2.0

hipclang release v3.2.0

HIP for HC Direct Function Call EAP

These packages are provided for use in tandem with the HC EAP that adds direct function call support: https://github.com/RadeonOpenCompute/hcc/releases. There are no other modifications. Minimal testing has been conducted on Ubuntu 16.04 and 18.04.

PyTorch EAP

This is a non-modified version of the 1.9.2 HIP codebase compiled with the PyTorch specific HCC EAP available here: https://github.com/RadeonOpenCompute/hcc/releases/tag/roc-1.9.2-pytorch-eap. It adds no features and exposes no behavioural differences by rapport with the released 1.9.2 version, and is only intended to be used with the aforementioned version of HCC. It has been verified with:

• Ubuntu 16.04/18.04
• CentOS 7.5 with Developer Toolset 7.

• Enabled device side assert support
• Several bug fixes including hipMallocArray, hipTexture fetch
• Support for RHEL/CentOS 7.4
• Updates to hipify-perl, hipify-clang and documentation

Notes:

• The code has been tested using HCC tagged version preview_1.0.17403.

preview_1.3.17333

3. Added new field to hipDeviceProp_t -> gcnArch which returns 803, 700, 900 etc.,

Bug Fixes:

1. Added return status check for module_api
2. Fixed Copyright and header names
3. Fixed issue with bit_extract sample
4. Enable lgamma and lgammaf

6. Fixed few issues with operator overloading of vector data types
7. Fixed atanf
8. Added guard for __half data types to work with clang version more than 3. (Will be removed eventually).
9. Fixed 4_shfl to work only for gfx803 as hawaii don't support permute ops
