sergei bd5ce35130 * m68k: completely replaced 64-bit comparison code with a clone of i386 implementation. No optimizations yet, but it already makes system unit about 300 instructions shorter due to changing node location to LOC_JUMP.
* Cleaned up 32-bit comparison code and implemented one of the optimizations (TST instruction for comparison with constant zero which can act directly on references). This makes system unit shorter by about 1000 instructions.

aasmcpu.pas * m68k: initial support for ROL/ROR operations, defining 'cpurox' for CPU target can actually enable them. However it cannot be done outright because these instructions do not exits on Coldfire, and internal processing of RoX,Sar,BsX, etc. can not yet be switched depending on CPU subtype. 2014-06-29 17:49:30 +00:00

cgcpu.pas * m68k: fixed extension in a_load_ref_reg. Existing code cleans only bits 16-31 when loading a 8-bit register from 16-bit reference, and leaves garbage in bits 8-15. 2014-07-24 12:17:29 +00:00

cpunode.pas m68k: cleaned up and fixed cgcpu/fixref for coldfire at least; also enabled n68kmem node, so addressing with scaling is generated now 2014-06-21 21:36:48 +00:00
cpupara.pas * m68k: support stack cleanup at caller side, fixed calculation of pushed parameters size and offsets and cleaned out another pile of junk. 2014-07-08 19:08:56 +00:00

n68kmat.pas * m68k: Transform 32-bit div/mod nodes into helper calls during pass 1. This is consistent with the way other targets do it, and results in pretty much nicer code. 2014-06-28 13:28:01 +00:00
n68kmem.pas m68k: tweaks and fixes in n68kmem. the node is still disabled, needs further fixes in cgcpu/fixref to work properly 2014-06-20 11:49:38 +00:00
