[LLVMdev] Question about post RA scheduler
I am having trouble trying to enable post RA scheduler for the Mips backend.
This is the bit code of the function I am compiling:
(gdb) p MF.Fn->dump()
define void @PointToHPoint(%struct.HPointStruct* noalias sret
%agg.result, %struct.ObjPointStruct* byval %P) nounwind {
entry:
%res = alloca %struct.HPointStruct, align 8
%x2 = bitcast %struct.ObjPointStruct* %P to double*
%0 = load double* %x2, align 8
The third instruction is loading the first floating point double of
structure %P which is being passed by value.
This is the machine fu...

[LLVMdev] Question about post RA scheduler
...ferPointerInfo in SelectionDAG.cpp cannot discover a load or store
is accessing a stack object (it can only infer the information if the
expression for the pointer is simple, for example add FI + const).
An alternative approach might be to make the machinepointerinfo of the
stores refer to %struct.ObjPointStruct* byval %P or refer to nothing,
but that currently doesn't seem to be possible.

I've thought of several ways we could potentially handle this. All are fairly messy without recognizing the situation during argument lowering. I'm not very familiar with the argument lowering code. But...
