There are target hooks to suppress the generation of lookup
tables, if you need that. See shouldBuildLookupTables and
shouldBuildLookupTablesForConstant in TargetTransformInfo. If you
need something beyond that, you'll have to modify the transform.
You can set a section on a global, but it sounds like that isn't
what you want?<br>
<br>
In terms of putting IR globals into a function, the only precedent
I can think of is the arm-constant-promote transform.</blockquote>

Err, sorry, I meant "arm-promote-constant"; see
promoteToConstantPool in ARMISelLowering.cpp.<br>
