[LLVMdev] Fwd: Segment Register Use
...a table with ids) in short, trying to do such a thing for complex data sets, especially when the result set or value dictates where to go next, using the linear sequence lookup to a register as defined in most current compilers, simply cant work. Doing so is (assume 2 usable registers for data) (lookupflops*numdatablocks)^2 for math processing. Even linearized, you need a test for eol using stack and ... well stacks break with recursion. Im sure there are documents describing this type and other similar models that function transparently on any hardware host. Obviously preparing large data sets in...

[LLVMdev] Segment Register Use
I realize I am one of the few who uses the segment registers (especially CS and DS) on the ia32 chips for example, and a definite few with complete segregation models that rival specialized physical processors... GCC still fails to use these correctly and if your LLVM still depends on either Generic or some of the RTL models they use in various processor definitions, I express concern for
