Evan Cheng 14c53b45f5 Added field noResults to Instruction.
Currently tblgen cannot tell which operands in the operand list are results so
it assumes the first one is a result. This is bad. Ideally we would fix this
by separating results from inputs, e.g. (res R32:$dst),
(ops R32:$src1, R32:$src2). But that's a more distruptive change. Adding
'let noResults = 1' is the workaround to tell tblgen that the instruction does
not produces a result. It works for now since tblgen does not support
instructions which produce multiple results.

Andrew Lenharth b9aaea3564 Unify the patterns for loads and stores. Now offset addressing should be
supported.  This almost completes memory operations.

Andrew Lenharth 4621488965 Let's see if we can break things.

llvm-svn: 24535
2005-11-30 16:10:29 +00:00
Andrew Lenharth 6db615df14 All sorts of stuff.
Getting in on the custom lowering thing, yay
evilness with fp setcc, yuck
trivial int select, hmmm
in memory args for functions, yay
DIV and REM, always handy.  They should be custom lowered though.

Lots more stuff compiles now (go go single source!).  Of course, none of it
probably works, but that is what the nightly tester can find out :)
