+
+ * mips-tdep.c, mipsread.c, tm-mips.h: Get rid of ".gdbinfo."
+ symbol. #define MIPS_EFI_SYMBOL_NAME instead. Use different
+ value so that demangler won't be invoked. This greatly speeds up
+ stepping.
+ * mips-tdep.c (mips_pop_frame): Rewrite handling of
+ linked_proc_info so that it properly deallocates the appropriate
+ item after it is done with it instead of before.
+ * Don't pass bogus frame pointer to create_new_frame(). Just
+ leave it as zero so that lower level code will figure out the
+ correct value.
