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.

Duraid Madina b43eb8c75b HP aCC chokes on this, but it's not required anyway: according to
the bzip2 homepage, only ancient (gcc 2.7.x ?) versions of GCC
require this? It certainly isn't needed for the current bzip2
sources.

Duraid Madina 36501f5eb0 MERRY CHRISTMAS EVERYONE!!! (what better way to spend christmas than
to try building LLVM on HP-UX! (the Right Way seems to be to tear out
the ancient STL that HP ship and use http://incubator.apache.org/stdcxx/ )

Andrew Lenharth 5b18ed9e60 All addressing modes are now exposed. The only remaining relocated forms
are for function prologue.

TODO: move external symbols over to using RelLit.

Evan Cheng 9ae486047e * Removed the use of FLAG. Now use hasFlagIn and hasFlagOut instead.
* Added a pseudo instruction (for each target) that represent "return void".
  This is a workaround for lack of optional flag operand (return void is not
  lowered so it does not have a flag operand.)

Chris Lattner 5ee896aad9 implement vastart. The dag isel compiles this:
void test3(va_list Y);
void test2(int F, ...) {
  va_list X;
  va_start(X, F);
  test3(X);
}

into this:

test2:
        save -104, %o6, %o6
        st %i5, [%i6+88]
        st %i4, [%i6+84]

        add %i6, 72, %o0
        st %o0, [%i6+-4]
        call test3
        nop
        restore %g0, %g0, %g0
        retl

The simple isel emits:
