Jeppe Johansen	2227045e23	Replace forbidden chars in more places in the GAS assembler writer. ... Add support for .set and .weak on AVR. Fix 64 bit negation on AVR. Add cpu_capabilities to cpuinfo.pas and fixed some peephole optimizations. Pass >4 byte parameters by reference. git-svn-id: trunk@26943 -	2014-03-04 08:01:23 +00:00
Jeppe Johansen	e33550b67d	Added support for X,Y,and Z register aliases plus low/high forms, and post-incrementation in AVR assembler reader. ... 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. git-svn-id: trunk@26925 -	2014-03-02 15:37:24 +00:00
