<DIV>Hello,</DIV>
<DIV>My target has two data memories, each with its own load/store instructions
but also has some instructions using both memories. I want to be able to access
both memories in C-programs through the address space attribute.</DIV>
<DIV>I have two ideas so far:</DIV>
<DIV>Either: use two sets of addressing modes in InstrInfo.td:</DIV>
<DIV><FONT size=2>def ADDRrr_A : ComplexPattern<i16, 2, “SelectADDRrr_A", [],
[]>;</FONT></DIV>
<DIV><FONT size=2>def ADDRri : ComplexPattern<i16, 2, "SelectADDRri",
[frameindex], []>;</FONT></DIV>
<DIV>and</DIV>
<DIV><FONT size=2>def ADDRrr_B : ComplexPattern<i16, 2, "SelectADDRrr_B", [],
[]>;</FONT></DIV>
<DIV> </DIV>
<DIV>Or: do something in one of the lowering functions to catch load and stores,
look at their address space attribute to pick the right assembly
instruction</DIV>
<DIV> </DIV>
<DIV>Can someone hint me on how this can be implemented? Any input would be
greatly appreciated. </DIV>
