fsincos registers swapped

a/b · 13 December 2023, 03:15

Instruction: fsincos.l #0,fp3:fp5 (or fp3,fp5 depending on assembler)
Opcode: f23c 42b3 00000000
M68K prgref pages 5-121/122: FSINCOS.X FPm,FPc,FPs => FPc bits 0-2, FPs bits 7-9
WinUAE debugger shows: fsincos.l #$00000000,fp5,fp3 (should be fp3,fp5)
Result is OK (fp3 is 1.0, fp5 is 0.0), it's just printed out in the wrong order.
