* 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.

||||
