Without the patch, the following gcc-11 compiler warnings are emitted for gdb-10.2/gdb/symtab.c: symtab.c: In function 'void gdb_get_datatype(gnu_request*)': symtab.c:7131:31: warning: ISO C++17 does not allow 'register' storage class specifier [-Wregister] 7131 | register struct type *type; | ^~~~ symtab.c:7132:31: warning: ISO C++17 does not allow 'register' storage class specifier [-Wregister] 7132 | register struct type *typedef_type; | ^~~~~~~~~~~~ ... Usually we don't fix compiler warnings for gdb, but these are emitted even by "make clean ; make warn", which doesn't recompile the whole gdb, so it would be better to fix.
