Fixed multiplication code generation for AVR controllers without mul instructions.
Added handling of the old interrupt procedure directive such that procedures with that use RETI instead of RET.
git-svn-id: trunk@31030 -
Cleaned up parameter and funcretloc information generation in AVR paramanger, and made it closer to GCC's calling convention.
Fixed a number of codegenerator bugs generating invalid or broken instructions: CP operands were swapped, a number of instructions had immediate operands, and stack frame epilogue wasn't complete.
Added a bunch of peephole optimizations that clears the generated code up a lot.
