Thanks for the explanation, makes sense.

Done:
TODO We're currently not streaming location information for the OpenMP
directives used in 'requires-7-aux.c', so we're not seeing the source file
name here (but a temporary '*.o' instead; for details, see
<https://gcc.gnu.org/pipermail/gcc-patches/2022-July/598011.html>):
{ dg-note {requires-7-aux\.c' has 'unified_address'} {} { xfail *-*-* } 0 }
..., but we may still verify that the rest of the diagnostic is correct:
{ dg-note {' has 'unified_address'} {} { target *-*-* } 0 }
With just that changed, I've pushed to master branch
commit faa0c328ee65f0d6d65d6e20181d26e336071919
"Fix one issue in OpenMP 'requires' directive diagnostics", see attached.

Subject: [PATCH] Fix one issue in OpenMP 'requires' directive diagnostics
Fix-up for recent commit 683f11843974f0bdf42f79cdcbb0c2b43c7b81b0
"OpenMP: Move omp requires checks to libgomp".

'fn2' computation.
libgomp/
* testsuite/libgomp.c-c++-common/requires-1.c: Add 'dg-note's.
* testsuite/libgomp.c-c++-common/requires-2.c: Likewise.
