This eclass provides utilities for ROCm libraries in
https://github.com/ROCmSoftwarePlatform, e.g. rocBLAS, rocFFT.
It contains a USE_EXPAND, amdgpu_targets_*, which handles the GPU
architecture to compile, and keep targets coherent among dependencies.
Packages that depend on ROCm libraries, like cupy, can also make use of
this eclass, mainly specify GPU architecture and it's corresponding
dependencies via USE_EXPAND.

+# @BLURB: Common functions and variables for ROCm packages written in HIP
+# @DESCRIPTION:
+# ROCm packages such as sci-libs/<roc|hip>*, and packages built on top of ROCm
+# libraries, can utilize variables and functions provided by this eclass.
+# It handles the AMDGPU_TARGETS variable via USE_EXPAND, so user can
+# edit USE flag to control which GPU architecture to compile. Using
+# ${ROCM_USEDEP} can ensure coherence among dependencies. Ebuilds can call the
+# function get_amdgpu_flag to translate activated target to GPU compile flags,
+# passing it to configuration. Function check_amdgpu can help ebuild ensure
+# read and write permissions to GPU device in src_test phase, throwing friendly
+# error message if unavailable.
+#
+# @EXAMPLE:
+# Example ebuild for ROCm library in https://github.com/ROCmSoftwarePlatform
+# which uses cmake to build and test, and depends on rocBLAS:
+# @CODE
+# ROCM_VERSION=${PV}
+# inherit cmake rocm
+# # ROCm libraries SRC_URI is usually in form of:
+# SRC_URI="https://github.com/ROCmSoftwarePlatform/${PN}/archive/rocm-${PV}.tar.gz -> ${P}.tar.gz"
+# S=${WORKDIR}/${PN}-rocm-${PV}
+# SLOT="0/$(ver_cut 1-2)"
+# IUSE="test"
+# REQUIRED_USE="${ROCM_REQUIRED_USE}"
+# RESTRICT="!test? ( test )"
+#
+# RDEPEND="
+# dev-util/hip
+# sci-libs/rocBLAS:${SLOT}[${ROCM_USEDEP}]
+# "
+#
+# src_configure() {
+# # avoid sandbox violation
+# addpredict /dev/kfd
+# addpredict /dev/dri/

+# -DAMDGPU_TARGETS="$(get_amdgpu_flags)"
+# -DBUILD_CLIENTS_TESTS=$(usex test ON OFF)
+# )
+# CXX=hipcc cmake_src_configure
+# }
+#
+# src_test() {
+# check_amdgpu
+# # export LD_LIBRARY_PATH=<path to built lib dir> if necessary
+# cmake_src_test # for packages using the cmake test
+# # For packages using a standalone test binary rather than cmake test,
+# # just execute it (or using edob)
+# }
+# @CODE
+#
+# Examples for packages depend on ROCm libraries -- a package which depends on
+# rocBLAS, uses comma separated ${HCC_AMDGPU_TARGET} to determine GPU
+# architectures, and requires ROCm version >=5.1
+# @CODE
+# ROCM_VERSION=5.1
+# inherit rocm
+# IUSE="rocm"
+# REQUIRED_USE="rocm? ( ${ROCM_REQUIRED_USE} )"
+# DEPEND="rocm? ( >=dev-util/hip-${ROCM_VERSION}
+# >=sci-libs/rocBLAS-${ROCM_VERSION}[${ROCM_USEDEP}] )"
+#
+# src_configure() {
+# if use rocm; then
+# local amdgpu_flags=$(get_amdgpu_flags)
+# export HCC_AMDGPU_TARGET=${amdgpu_flags//;/,}
