For some reason, split1 pass converts (insn):

(insn 54 51 109 9 (parallel [
            (asm_operands/v ("btrl %1,%0") ("") 0 [
                    (mem/c:BLK (plus:DI (plus:DI (unspec:DI [
                                        (const_int 0 [0])
                                    ] UNSPEC_TP)
                                (reg:DI 100))
                            (const_int 96 [0x60])) [21 MEM[(struct
revectored_struct *)&vm86u + 96B]+0 S32 A32])
                    (reg:SI 101)
                ]
                 [
                    (asm_input:BLK ("m") ../../../src/include/cpu.h:355)
                    (asm_input:SI ("r") ../../../src/include/cpu.h:355)
                ]
                 [] ../../../src/include/cpu.h:355)
            (clobber (reg:CC 17 flags))
        ]) "../../../src/include/cpu.h":355:2 -1
     (expr_list:REG_DEAD (reg:SI 101)
        (expr_list:REG_DEAD (reg:DI 100)
            (expr_list:REG_UNUSED (reg:CC 17 flags)
                (nil)))))

to (jump_insn):

(jump_insn 111 51 113 9 (parallel [
            (asm_operands/v ("btrl %1,%0") ("") 0 [
                    (mem/c:BLK (plus:DI (reg:DI 100)
                            (const_int 96 [0x60])) [21 MEM[(struct
revectored_struct *)&vm86u + 96B]+0 S32 A32 AS1])
                    (reg:SI 101)
                ]
                 [
                    (asm_input:BLK ("m") ../../../src/include/cpu.h:355)
                    (asm_input:SI ("r") ../../../src/include/cpu.h:355)
                ]
                 [] ../../../src/include/cpu.h:355)
            (clobber (reg:CC 17 flags))
        ]) "../../../src/include/cpu.h":355:2 -1
     (nil))

This confuses sched2 pass.
