Chris Lattner 1813aabcf2 new testcase 
llvm-svn: 23380
 2005-09-18 05:10:39 +00:00
Chris Lattner af517574ce Implement add.ll:test29. Codegening: 
struct S { unsigned int i : 6, j : 11, k : 15; } b;
void plus1 (unsigned int x) {
  b.i += x;
}

as:
_plus1:
        lis r2, ha16(L_b$non_lazy_ptr)
        lwz r2, lo16(L_b$non_lazy_ptr)(r2)
        lwz r4, 0(r2)
        add r3, r4, r3
        rlwimi r3, r4, 0, 0, 25
        stw r3, 0(r2)
        blr

instead of:

_plus1:
        lis r2, ha16(L_b$non_lazy_ptr)
        lwz r2, lo16(L_b$non_lazy_ptr)(r2)
        lwz r4, 0(r2)
        rlwinm r5, r4, 0, 26, 31
        add r3, r5, r3
        rlwimi r3, r4, 0, 0, 25
        stw r3, 0(r2)
        blr

Chris Lattner 1521298993 Implement or.ll:test21. This teaches instcombine to be able to turn this: 
struct {
   unsigned int bit0:1;
   unsigned int ubyte:31;
} sdata;

void foo() {
  sdata.ubyte++;
}

into this:

foo:
        add DWORD PTR [sdata], 2
        ret

instead of this:

foo:
        mov %EAX, DWORD PTR [sdata]
        mov %ECX, %EAX
        add %ECX, 2
        and %ECX, -2
        and %EAX, 1
        or %EAX, %ECX
        mov DWORD PTR [sdata], %EAX
        ret

llvm-svn: 23370
 2005-09-16 00:29:46 +00:00
Chris Lattner 59e96143a2 teach the type inference code how to infer types for instructions and node 
xforms.  Run type inference on result patterns, so we always have fully typed
results (and to catch errors in .td files).

 2005-09-14 23:05:13 +00:00
Chris Lattner 991c7c973a Promote xform fns to be explicit nodes in result patterns, and clean off 
predicates since they will have already matched at this point.

llvm-svn: 23362
 2005-09-14 23:01:59 +00:00
Chris Lattner bc7aabce12 start building the instruction dest pattern correctly. Change the xform 
functions to preserve the Record for the xform instead of making it into a
function name.

 2005-09-14 20:53:42 +00:00
Chris Lattner f006d15e7f Fix some issues exposed by more testing. XORIS had the wrong operands 
specified.  The various *imm operands defined by PPC are really all i32,
even though the actual immediate is restricted to a smaller value in it.

Chris Lattner 0f965a615e Change the arg lowering code to use copyfromreg from vregs associated 
with incoming arguments instead of the pregs themselves.  This fixes
the scheduler from causing problems by moving a copyfromreg for an argument
to after a select_cc node (now it can, and bad things won't happen).
