--- Comment #5 from Jim Wilson <wilson at gcc dot gnu.org> ---
I tested it with an rv64gc-linux cross compiler.  The patch fixes these
failures:
FAIL: gcc.dg/pr94780.c (internal compiler error)                                
FAIL: gcc.dg/pr94780.c (test for excess errors)                                 
FAIL: gcc.dg/pr94842.c (internal compiler error)                                
FAIL: gcc.dg/pr94842.c (test for excess errors)
There are no regressions.

I think it should be backported to the gcc-10 release branch.
