I just got to looking at my test cases and I have successfully compiled all of my test cases that are derivatives of actual memory initialization code with -O2 and no extra registers.
It also translates the K8 smbus_write_byte() function now.. great!
Which is a very good sign for the case of using extra registers to avoid inlining subroutines.
Does this mean we can push the size of the linuxbios image down noticably now?
That is the goal. .36 allows static const variables outside of functions, and does not duplicate them when they are inside of functions.
-O2 helps a little bit.
I am just starting on not inlining function calls. Once that is working we can see if there is noticeable size decrease. I expect that to be the case, but you never know until you try.
