* tc-arm.c (struct arm_it): Make operands.imm signed to match its
|
||||
use an immediate value.
|
||||
(parse_vfp_reg_list): Make the 2nd parameter an unsigned pointer
|
||||
since the register field of the operands structure is unsigned.
|
||||
(s_arm_unwind_save_vfp): Make "reg" unsigned.
|
||||
(parse_operands): Make the 2ns parameter an unsigned pointer to
|
||||
match its use.
|
||||
(do_ldrd): When using the imm field of the operands structure as a
|
||||
second register field, treat it as unsigned.
