go to the same destination. Now we're producing really good code for
switch-lower-feature.ll testcase

Reid Spencer d1b53f538d For PR1302:
Use local variable names that match the function parameter name that it
is passed to so the code is more clear, to wit: is_bytecode -> is_native

Nicolas Geoffray 23710a7da3 Starting implementation of the ELF32 ABI specification of varargs handling.
LowerVASTART emits the right code if the subtarget is ELF32, the other intrinsics
(VAARG, VACOPY and VAEND) are not yet implemented.

Nicolas Geoffray b3e99a18ee The PPC64 ELF ABI is "intended to use the same structure layout and calling convention rules
as the 64-bit PowerOpen ABI" (Reference http://www.linux-foundation.org/spec/ELF/ppc64/).
Change all ELF tests to ELF32.

Nicolas Geoffray ab559f6e3c Addition to the previous commit for getCalleeSavedRegClasses:
"The ELF ABI specifies F1-F8 registers as argument registers for double, not
F1-F10. This affects only ELF, not MachO."

Chris Lattner f742e2fe70 Arm supports negative strides as well, add them. This lets us compile:
CodeGen/ARM/arm-negative-stride.ll to:

LBB1_2: @bb
        str r1, [r3, -r0, lsl #2]
        add r0, r0, #1
        cmp r0, r2
        bne LBB1_2      @bb

Scott Michel 16627a542f 1. Insert custom lowering hooks for ISD::ROTR and ISD::ROTL.
2. Help DAGCombiner recognize zero/sign/any-extended versions of ROTR and ROTL
patterns. This was motivated by the X86/rotate.ll testcase, which should now
generate code for other platforms (and soon-to-come platforms.) Rewrote code
slightly to make it easier to read.

Zhou Sheng 9bc8ab100d 1. Make use of APInt operation instead of using ConstantExpr::getXXX.
2. Use cheaper APInt methods.

Chris Lattner 28e0e4e11e Pass the type of the store access, not the type of the store, into the
target hook.  This allows us to codegen a loop as:

LBB1_1: @cond_next
        mov r2, #0
        str r2, [r0, +r3, lsl #2]
        add r3, r3, #1
        cmn r3, #1
        bne LBB1_1      @cond_next

instead of:

LBB1_1: @cond_next
        mov r2, #0
        str r2, [r0], #+4
        add r3, r3, #1
        cmn r3, #1
        bne LBB1_1      @cond_next

This looks the same, but has one fewer induction variable (and therefore,
one fewer register) live in the loop.

Chris Lattner 3e21eb7fd7 Fix a bug which caused us to never be able to use signed comparisons for
equality comparisons of a constant.  This allows us to codegen the 'sintzero'
loop in PR1288 as:

LBB1_1: ;cond_next
        li r4, 0
        addi r2, r2, 1
        stw r4, 0(r3)
        addi r3, r3, 4
        cmpwi cr0, r2, -1
        bne cr0, LBB1_1 ;cond_next

instead of:

LBB1_1: ;cond_next
        addi r2, r2, 1
        li r4, 0
        xoris r5, r2, 65535
        stw r4, 0(r3)
        addi r3, r3, 4
        cmplwi cr0, r5, 65535
        bne cr0, LBB1_1 ;cond_next

This implements CodeGen/PowerPC/compare-simm.ll, and also cuts 74
instructions out of kc++.
