Errononous scheduling of COPY instruction.
Hi,
I've instruction scheduling problem that I cannot further investigate by myself... Could someone give me some clues?
After Instruction selection, here is part of the generated instruction.
NOP
MOV_AB_ro @s1, %fab_roff0
%6:fpuaoffsetclass = COPY %fab_roff0; FPUaOffsetClass:%6
MOV_A_oo %6, def %5; FPUaOffsetClass:%6,%5
MOVSUTO_A_iSLo 24575, def %7; FPUaOffsetClass:%7
The order of instruction is very important: the COPY shall take place after the MOV_AB_ro!
But during Instruction scheduling...
