re PR bootstrap/38578 (fatal warning during bootstrap on arm.c for output_move_double and arm_expand_prologue)
PR bootstrap/38578
* arm.c (load_multiple_sequence): Initialize ORDER array.
(store_multiple_sequence): Likewise.
(output_move_double): Make reg0 unsigned.
(arm_output_epilogue): Make amount unsigned.
(arm_expand_prologue): Move declaration of dwarf before block
statements.
