Evan Cheng 94b5a80b93 Change instruction description to split OperandList into OutOperandList and
InOperandList. This gives one piece of important information: # of results
produced by an instruction.
An example of the change:
def ADD32rr  : I<0x01, MRMDestReg, (ops GR32:$dst, GR32:$src1, GR32:$src2),
                 "add{l} {$src2, $dst|$dst, $src2}",
                 [(set GR32:$dst, (add GR32:$src1, GR32:$src2))]>;
=>
def ADD32rr  : I<0x01, MRMDestReg, (outs GR32:$dst), (ins GR32:$src1, GR32:$src2),
                 "add{l} {$src2, $dst|$dst, $src2}",
                 [(set GR32:$dst, (add GR32:$src1, GR32:$src2))]>;

from constant pools, while others are always rematerializable. This hook
allows both to be identified as being rematerializable with the same

Reid Spencer c23c9fce34 The Intrinsic::getDeclaration function's Tys parameter only contains the

Without this option the script will continue to check out from CVS. To

-svnurl followed by the URL. For now, -svnurl will default to Reid's

Reid Spencer e67d0c226d For PR1297:
Implement code generation for overloaded intrinsic functions. The basic
difference is that "actual" argument types must be provided when

suffix is checked by the Verifier, however.

Bill Wendling 98d2104c6f Add support for the v1i64 type. This makes better code for this:
#include <mmintrin.h>

extern __m64 C;

void baz(__v2si *A, __v2si *B)
{
  *A = C;
  _mm_empty();
}

We get this:

_baz:
        call "L1$pb"
"L1$pb":
        popl %eax
        movl L_C$non_lazy_ptr-"L1$pb"(%eax), %eax
        movq (%eax), %mm0
        movl 4(%esp), %eax
        movq %mm0, (%eax)
        emms
        ret

GCC gives us this:

_baz:
        pushl   %ebx
        call    L3
"L00000000001$pb":
L3:
        popl    %ebx

Reid Spencer 7a9c62baa6 For PR1064:
Implement the arbitrary bit-width integer feature. The feature allows
integers of any bitwidth (up to 64) to be defined instead of just 1, 8,
16, 32, and 64 bit integers.

This change does several things:
1. Introduces a new Derived Type, IntegerType, to represent the number of
   bits in an integer. The Type classes SubclassData field is used to
   store the number of bits. This allows 2^23 bits in an integer type.
2. Removes the five integer Type::TypeID values for the 1, 8, 16, 32 and
   64-bit integers. These are replaced with just IntegerType which is not
   a primitive any more.
3. Adjust the rest of LLVM to account for this change.

Note that while this incremental change lays the foundation for arbitrary
bit-width integers, LLVM has not yet been converted to actually deal with
them in any significant way. Most optimization passes, for example, will
still only deal with the byte-width integer types.  Future increments
will rectify this situation.

is implicit.

Chris Lattner f405928e86 Special case tblgen generated code for patterns like (and X, 255) or (or X, 42).
The dag/inst combiners often 'simplify' the masked value based on whether
or not the bits are live or known zero/one.  This is good and dandy, but
often causes special case patterns to fail, such as alpha's CMPBGE pattern,
which looks like "(set GPRC:$RC, (setuge (and GPRC:$RA, 255), (and GPRC:$RB, 255)))".
Here the pattern for (and X, 255) should match actual dags like (and X, 254) if
the dag combiner proved that the missing bits are already zero (one for 'or').

For CodeGen/Alpha/cmpbge.ll:test2 for example, this results in:

        sll $16,1,$0
        cmpbge $0,$17,$0
        ret $31,($26),1

instead of:

        sll $16,1,$0
        and $0,254,$0
        and $17,255,$1
        cmpule $1,$0,$0
        ret $31,($26),1

Chris Lattner 13a5dcddce Fix a long-standing wart in the code generator: two-address instruction lowering
actually *removes* one of the operands, instead of just assigning both operands

because you need to know if you are before or after register allocation to match
up operand #'s with the target description file.

Changing this also gets rid of a bunch of hacky code in various places.

Patrick Jenkins 06725191ab Corrected an error that was introduced yesterday that caused the GCC
version to be left blank if the build failed.

Also corrected a problem where if the build failed the nightly tester
would still try to read the results of the Dejagnutests log even
though it didnt exist.

Patrick Jenkins 235abe4ce8 The new nightly tester should stop outputing a message stating the
testresults directory is not present unless the script is run as verbose.

Patrick Jenkins deb77ee8eb These changes reflect the changes in the database for how tests are stored
and bring the handing of dejagnu tests into compliance with this new scheme.

Patrick Jenkins d515016982 Changing the format dejagnu tests are submitted. We used to only submit multisource information for pass fail. Now we submit all pass/fail test information. This should fix the issue where some results were not being reported.
