 This period is binary. It compiles or it does not. There is no incremental improvement here. I learned a lot and actually changed my ISA a bit because of what I learned doing this. But, I do not remember anything I did here. It is a black hole. I've probably blocked it out of my memory. It was that horrifying.

+=== Notes from April/May
-A sudden thrust of energy, cola and Doritos and the back-end was in sight. A lot of this was fueled by excitement over many small wins. Such as getting something to work. Once I saw it start to emit SDA assembly I was hooked. Many small changes to the assembler were made too, to support LLVM stuff that I didn't want to try and lower out.

 * That stupid string that looks like e-p:32:8-i16:8-i32:8-i64:8-n16 is in:
 ** ''llvm/lib/TargetParser/TargetDataLayout.cpp''
+//Total cost of this note alone: Probably 6 hours.//
 * COMMON files I need to find:

 * Look very carefully at the error message. 90% of the time you're missing a header, a function declaration, or something's type is wrong. The solution is often easier than you think.
 * Use git or you will mess stuff up and be unable to go back.

+A sudden thrust of energy, cola and Doritos and the back-end was in sight. A lot of this was fueled by excitement over many small wins. Such as getting something to work. Once I saw it start to emit SDA assembly I was hooked. Many small changes to the assembler were made too, to support LLVM stuff that I didn't want to try and lower out. One example of an extreme change I made was to remove MOV touching the zero flag because I couldn't figure out how to set it in the files. Its supposed to be [SR] (status register). But there are multiple places you're supposed to add it and I started hallucinating that I had added it in certain places then when I went back to check it was gone. Whatever, I'll just remove the flags from MOV! Now i'm done with that part. HAHA. Hehe hoho.
+Suddenly I was out of the tunnel and I didn't even realize it. I decided to skip some stuff that would have made the generated code "better". Like jumptables and some function calls (that are instead inlined, which bloats code).
+* Remember: jumptables for large switches
+* Remember: mul and div calling functions versus inlining
