Wed Dec 23 10:27:44 1998 Nick Clifton <nickc@cygnus.com>
* config/arm/t-arm-elf: Add multiplib option for leading
underscores.
* config/arm/thumb.h (ASM_OUTPUT_LABELREF): Use variable
'user_label_prefix' rather than macro USER_LABEL_PREFIX.
(thumb_shiftable_const): Use macro 'BASE_REG_CLASS' rather
than variable 'reload_address_base_reg_class'. [Note this
change is unrelated to the others in this patch].
* config/arm/unknown-elf.h (USER_LABEL_PREFIX): Default to no
leading underscore.
Wed Dec 23 09:51:32 1998 Kaveh R. Ghazi <ghazi@caip.rutgers.edu>
* alias.c (record_alias_subset): Remove ignored `&'.
