Issue
VLE I16L-form instructions (
e_and2i,e_and2is,e_or2i,e_or2is,e_lis)decoded incorrect immediate values due to wrong bit mask.
Fix
Changed
ui0_4mask from0xf(4-bit) to0x1f(5-bit) to match PowerPC VLEI16L-form specification where UI = ui[0-4] || ui[5-15].
Impact
Immediate values are now correctly parsed for all I16L-form instructions.
