2001-06-11 Nick Clifton <nickc@cambridge.redhat.com>
* config/m32r/m32r.md (movstrsi_internal): Do not expect a
return string from m32r_output_block_move.
* config/m32r/m32r-protos.h: Make m32r_output_block_move a
void function.
* config/m32r/m32r.h (INT32_P): Rename to UNIT32_P and remove
integer overflow.
(ROUND_ADVANCE): Remove signed/unsigned conflict.
* config/m32r/m32r.c: Declare prototypes for static functions.
(move_src_operand): Replace INT32_P with UINT32_P.
(function_arg_partial_nregs): Fixed signed/unsigned conflict
in initialisation of 'size'.
(m32r_sched_reord): Remove redundant declarations of 'code'.
(m32r_output_block_move): Change to a void function.
(m32r_encode_section_info): Cast return of
TREE_STRING_POINTER to avoid compile time warning.
2001-06-11 Richard Henderson <rth@redhat.com>
* config/alpha/osf5.h (TARGET_LD_BUGGY_LDGP): New.
