-Subject: [PATCH] Fix uninitialised use in mips_split_move
-
-While testing the fix for PR91068, I hit an rtl checking failure
-while building newlib.  mips_split_move was decomposing an address that
-happened to be symbolic and then tried to access the REGNO of the base
-register field, which wasn't initialised but which by chance pointed to
-valid memory.
