[fpc-devel] ASM on Win64

Hello everyone,

Before asking too many questions already answered, is there any 
comprehensive up to date documentation of asm usage for the Win64 target?

(Yes, I have googled the archive of this list, but since the compiler is 
still under active development, I didn't think it might be a good idea 
to trust information posted here often more than two years ago. The 
information about the Win64 target that I found at 
http://www.freepascal.org/docs.html is either incomplete or missing 

I am in particular interested in:

1. Since there is no CPU debug window in Lazarus Win64, I tried the -A 
option, but it doesn't seem to work with the compiler bundled with 
Lazarus Win64. I tried -aASW, -AASW and a couple of other combinations. 
Am I missing something obvious?

2. I couldn't find information about the calling convention under Win64 
on the documentation page. Does FPC support the unified MSVC++ calling 
convention for Win64 that is very similar to Register+stack frames? Does 
it, like MSVC++, *only* support that calling convention?
