+ } else {
+ Args.ClaimAllArgs(options::OPT_fgpu_approx_transcendentals);
+ Args.ClaimAllArgs(options::OPT_fno_gpu_approx_transcendentals);
----------------
You can use `Args.claimAllArgs(options::OPT_fgpu_approx_transcendentals,
options::OPT_fno_gpu_approx_transcendentals);`

"-fgpu-approx-transcendentals"
+// APPROX: clang{{.*}} "-triple" "x86_64-unknown-linux-gnu" {{.*}}
"-fgpu-approx-transcendentals"
----------------
Just test `-cc1`: `// APPROX: "-cc1"{{.*}} "-triple" "amdgcn-amd-amdhsa" {{.*}}
"-fgpu-approx-transcendentals"`
Testing `clang` requires `-no-canonical-prefixes`

Comment at: clang/test/Driver/hip-options.hip:209
+
+// APPROXNEG-NOT: warning
----------------
If `%t` happens to be in a path with `warning` as a substring, this will
spuriously fail.
Suggest `%clang -fdriver-only -Werror... 2>&1 | count 0` to test that there is
no warning/error.
