Collapsed the inc/dec codegen into the loadEAX function, because it
allows us to generate better code for inc/dec'ing a global variable
on ARM, because we don't have to load the variable's address twice.
Added C++-style "//..end-of-line" comments, since I kept trying to use them when writing
test programs.
The biggest known missing piece is global variables.
+ Improved li to handle all 32-bit values.
+ Implemented push/pop of temp registers during evaluation
+ Implemented the unary and binary easy math operators (+,-,*,<<,>>,|,&,^,~)
+ Implemented global function calling.
This program works:
main() { return 42; }
The disassembler was borrowed from codeflinger, and just modified enough to compile
under C++ without warnings.
Implemented gsym
Implemented a hack verison of li, only works for -256..255
Implemented gjmp
+ Changed indentation, causes the stats to say there's a lot of lines changed.
+ Should be able to compile multiple times with the same compiler object.
+ Create a CodeBuffer class to hold the code.
+ Create a CodeGenerator class to encapsulate knowlege of the CPU instruction set.
+ Started filling in the code generator.
