Here is a script to reproduce the bug:

```bash
#! /usr/bin/env bash

set -x -u -e -o pipefail

version="${1:-18}"

CMAKE_BUILD_PARALLEL_LEVEL="$(nproc)"
export CMAKE_BUILD_PARALLEL_LEVEL="${CMAKE_BUILD_PARALLEL_LEVEL:-4}"

workspace="llvm-bug95484-${version}"

rm -rf "${workspace}"
mkdir "${workspace}"
cd "${workspace}"

git clone --depth 1 \
	--branch "release/${version}.x" \
	'https://github.com/llvm/llvm-project.git' \
	'llvm-project'

git clone --depth 1 \
	'https://github.com/KhronosGroup/SPIRV-Headers.git' \

	'https://github.com/KhronosGroup/SPIRV-LLVM-Translator.git' \

```

It can be used just by saving it as `llvm-bug95484` and running it by doing either:

- `./llvm-bug95484`
  to fetch and attempt a clean build of `release/18.x` in a way it reproduces the bug,
- `./llvm-bug95484 17`
  to fetch and reproduce the bug with `release/17.x`.

It will fail this way:

```
llvm-bug95484-18/llvm-project/openmp/libomptarget/plugins-nextgen/amdgpu/src/rtl.cpp:1902:37:
 error: ‘HSA_AMD_AGENT_INFO_TIMESTAMP_FREQUENCY’ was not declared in this scope;
 did you mean ‘HSA_SYSTEM_INFO_TIMESTAMP_FREQUENCY’?
