Comment (by ChrisKuklewicz):
The "lis hi16/ori lo16" instructions seem to only be from
compiler/nativeGen/MachCodeGen.hs line 1754
{{{
getRegister (CmmLit lit)
= let rep = cmmLitRep lit
imm = litToImm lit
code dst = toOL [
LIS dst (HI imm),
OR dst dst (RIImm (LO imm))
]
in return (Any rep code)
}}}
So that is probably the place to fix the code generation.
The above is then rendered to text by PpcMach.hs in the obvious way.
Replacing HI/hi16 by HA/ha16 and changing OR to the right kind of "la" or
"addi"
might fix it.
