Instruction Scheduling in the C2 Compiler

[Ahmed Khawaja]

Greetings,

            I am inquiring as to what would be a good starting point to 
get familiar with the current instruction scheduling capabilities of the 
C2 compiler in hotspot. I am relatively new to working with Hotspot and 
have primarily been working with the macro-assembler and will now be 
looking at the instruction scheduling abilities. I am going through the 
source code now but I am not exactly sure where instruction scheduling 
is done. The OpenJDK wiki also seems to be somewhat empty on this and 
the compiler passes in general.

Thanks in advance,
    Ahmed
