Missed a few last week... Grrr.
1998-07-23 * am33.igen: Autoincrement loads/store fixes.Jeff Law1-34/+253
1998-07-21 * am33.igen: Add most am33 DSP instructions.Jeff Law1-15/+3530
1998-07-09 * am33.igen: Fix Z bit for remaining addc/subc instructions.Jeff Law1-40/+47
Do not sign extend immediate for mov imm,XRn. More random mul, mac & div fixes. Remove some unused variables. Sign extend 24bit displacement in memory addresses. Whee, more fixes.
1998-07-09 * mn10300.igen: Fix Z bit for addc and subc instructions.Jeff Law1-20/+25
Minor fixes in multiply/divide patterns. start-sanitize-am33 * am33.igen: Fix Z bit for addc Rm,Rn and subc Rm,Rn. Various fixes to 2 register multiply, divide and mac instructions. Set Z,N correctly for sat16. Sign extend 24 bit immediate for add, and sub instructions. * am33.igen: Add remaining non-DSP instructions. end-sanitize-am33
1998-07-09 * am33.igen: Add remaining non-DSP instructions.Jeff Law1-20/+686
Lots of work still remains. PSW handing is probably broken badly and the mul/mac classes of instructions are probably not handled correctly.
