See [the documentation](https://cmake.org/cmake/help/v3.0/command/find_package.html)
for exactly how the search procedure works. If you want to use an
LLVM from a specific location, use CMAKE_PREFIX_PATH as normal.
No longer do we have a nonstandard HIPIFY_CLANG_LLVM_DIR variable
for people to learn about.
Instead of deciding whether to build hipify-clang based on
the presence of an LLVM path on the command line, have an
explicit option.
Do we want this default-on or default-off? I've defaulted it to
on for now, but maybe we want the opposite?
Cmake cache was being rebuilt on each build. This was being done
to update HIP_VERSION, HCC_VERSION, .hipInfo and .hipVersion.
However, rebuilding cache also re-runs HIT parser which is slow.
Removing the cache rebuild should speed up the build. But user
needs to explicitly rebuild the cache in case HIP_VERSION or
HCC_VERSION changes by calling "make rebuild_cache"

1. As in hipModuleLaunchKernel(..., kernelParams, nullptr); works with this commit
2. Added headers AMDGPUPTNote.h, AMDGPURuntimeMetadata.h to do code object meta data parsing
3. Changed CMake to look at llvm link libraries
4. HIP developer should set env variable LLVM_HOME to remove link errors
5. HIP depends on installed LLVM (not source, not build)
6. Added sample to test out the feature
7. Right now HCC does not support embedding metadata in code object. Use clang opencl
8. Changed HIPCC to read LLVM_HOME env var
9. New argument to CMake should be given -DLLVM_HOME=<where llvm 5.0 is installed>

- target "make test" will no longer build and run tests. It will only run the tests.
- added new target "make check" which will build and run the tests.
- target "make check" will build tests serially. Use -j<N> to build tests in parallel.

only force to libstdc++ if the g++ is older than version 5 since hcc already defaults to libstdc++ with newer g++

remove hardcoded -lc++ in tests

force include libstdc++ headers and stdc++ only if g++ version < 5 since hcc uses libstdc++ by default if g++ > 5 is present

(cherry picked from commit 866e744e40cf1378af8a679b54959bf5226c340f)
1. Split hip_ir.ll to hip_hc.ll and hip_hc_gfx803.ll
a. hip_hc.ll contains arch generic ir implementations
b. hip_hc_gfx803.ll contains gfx803 (fiji, polaris) specific ir
2. HIPCC can now parse --amdgpu-target=*.
a. Usage: hipcc --amdgpu-target=gfx803 --amdgpu-target=gfx701
b. TODO: Convert to --amdgpu-target=gfx803,gfx701
3. With LLC in HCC able to generate native f16 isa, removed inline half asm math ops
4. Fixed threadfence and threadfence_block to use functions in rocdl
Change-Id: Ic9a9e3e04139b0d75d2c2a263c030ca77adc1019
1. All fp32, fp64 math device/host functions should be in math_functions.h/.cpp
2. All fp32, fp64 fast math intrinsics for device/host functions should be in device_functions.h/.cpp
3. All the device code implementations should be in device_util.h/.cpp
4. Hence, made changes appropriately by moving code and creating new header files
5. Added math_functions.cpp/.h
6. Changed #ifndef signature to make sure no conflicts between headers with same names in hip/hip_runtime.h and hip/hcc_detail/hip_runtime.h
7. Changed tests to fit the code changes, making them to include appropriate headers
8. Added math_functions.cpp to CMakeLists.txt
9. Some of the tests are still broken, mostly host math functions will fix them in next commit
10. TODO: FIX compilation issues for host math functions
Change-Id: I7a17637d7e294a7d224ffba932c1a08668febd26
hipcc accepts new parameter -use-staticlib and -use-sharedlib to
control linking behavior. Default is still static library.
Change-Id: I28fb9a939f8177c75abefd8b77d8118a6666d1f4
1. Added feature for __threadfence and __threadfence_block
2. Added feature for using LLVM IR files directly while compilation
3. Added test for threadfence and threadfence_block
