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

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++.

Lauro Ramos Venancio 6be85337b0 - Divides the comparisons in two types: comparisons that only use N and Z
flags (ARMISD::CMPNZ) and comparisons that use all flags (ARMISD::CMP).
- Defines the instructions: TST, TEQ (ARM) and TST (Thumb).

Lauro Ramos Venancio 682baf2dda "The C standards do say that "char" may either be a "signed char" or "unsigned

followed."
