X64 calling convention

Is shown below:

pre-arg-push:
| 0xffff                 0 |
| ----- stack growth ----> |
[locals..., space-for-args]
|                        ^rsp

after-arg-push and pre-call (a1-a6 are passed in reg):
| 0xffff                 0 |
| ----- stack growth ----> |
[a9:16(rsp), a8:8(rsp), a7:0(rsp)]

after-call and pre-callee-save:
| 0xffff                 0 |
| ----- stack growth ----> |
[a9:24(rsp), a8:16(rsp), a7:8(rsp), retAddr:0(rsp)]

after-callee-save after-new-rbp
| where N = all pushes (including push rbp)
| 0xffff                 0 |
| ----- stack growth ----> |
[a9:8N+24(rbp), a8:8N+16(rbp), a7:8N+8(rbp), retAddr:8N(rbp), ...xN]
