[mod.computers.vax] Hidden floating point use?

ins_ajbh@JHUNIX.BITNET.UUCP (03/12/87)

Does an assembler instruction of the following form

 MOV      (R0)[R1], R3

kick in the floating point hardware on a 785? R0 points to a
array of longwords. The reason for the question is that I have a
program that runs much faster on a machine with FPA than on a
machine without FPA but has no obvious floating instructions. I could
see it evaluating "Address(R0) + 4*R1" this way.
