How to inline x64 asm in vs2017 ?

Hi Insid3Code. Not used any local variables inside. So the allocation is unnecessary I think. Even it can be shorter. Eg.

F1 PROC
PUSHAD
LEA RCX, TXT_F1
CALL puts
POPAD
F1 ENDP

More, your edited code should be:

F1 PROC
PUSH RBP
MOV RBP, RSP
SUB RSP, 40 ; Allocate space on the stack (8 for alignment and 32 for shadow space); Below of MOV RBP, RSP, this instruction already saved RSP to RBP.
LEA RCX, TXT_F1
CALL puts
LEAVE
ADD RSP, 40 ; Cleanup the stack... ; Not needed. The LEAVE instruction did it.
RET
F1 ENDP
