DESCRIPTION="Registration library that brokers profiler attachment to the ROCm runtimes"
HOMEPAGE="https://github.com/ROCm/rocm-systems/tree/develop/projects/rocprofiler-register"
# AMD retired rocm-* releases; use the rocprofiler-register asset from the
# matching TheRock release.
SRC_URI="https://github.com/ROCm/rocm-systems/releases/download/therock-$(ver_cut 1-2)/${PN}.tar.gz -> ${P}.tar.gz"

# Slot by ROCm release for closure rebuilds; the SONAME carries upstream's 0.6.0.

KEYWORDS="~amd64"

IUSE="test"
RESTRICT="!test? ( test )"

# The release omits its glog/fmt submodules, so disable configure-time fetching
# and use system libraries. Direct SONAME links require := rebuild operators.
