Calling convention for ASM on Linux AMD64

[Sean O'Connor]

Okay, cool, thanks for the information.  The main reason for 
using D versus Java for me at the moment is that array slices 
allow me avoid lots of intermediate buffers that Java is forcing 
me to use.
Also the line count is about 2/3 of Java. Further I can directly 
embed any assembly language I need, rather than using JNI.
Maybe some day a version of D for graal can be written, though 
you would lose native assembly language.

All I really want though is a sane low level programming language 
or a sane version of C.
