Benjamin Kramer 45e7d53cf4 Turn the enum attributes DenseSet in AttrBuilder into a set of bits.
Avoids malloc and is a lot denser. We lose iteration over target independent
attributes, but that's a strange interface anyways and didn't have any users
outside of AttrBuilder.

Reed Kotler 188dad0eeb One more try to make this look nice. I have lots of pseudo lowering
as well as 16/32 bit variants to do and so I want this to look nice
when I do it. I've been experimenting with this. No new test cases
are needed.

Christian Konig a881179ffe R600/SI: nuke SReg_1 v3
It's completely unnecessary and can be replace with proper
SReg_64 handling instead.

This actually fixes a piglit test on SI.

v2: use correct register class in addRegisterClass,
    set special classes as not allocatable
v3: revert setting special classes as not allocateable

This is a candidate for the stable branch.

Christian Konig c756cb9901 R600/SI: cleanup literal handling v3
Seems to be allot simpler, and also paves the
way for further improvements.

v2: rebased on master, use 0 in BUFFER_LOAD_FORMAT_XYZW,
    use VGPR0 in dummy EXP, avoid compiler warning, break
    after encoding the first literal.
v3: correctly use V_ADD_F32_e64

Derek Schuff 8878bcc9e7 If bundle alignment is enabled, do not add data to a fragment with instructions
With bundle alignment, instructions all get their own MCFragments
(unless they are in a bundle-locked group). For instructions with
fixups, this is an MCDataFragment. Emitting actual data (e.g. for
.long) attempts to re-use MCDataFragments, which we don't want int
this case since it leads to fragments which exceed the bundle size.
So, don't reuse them in this case.
Also adds a test and fixes some formatting.

Bill Wendling aef9c37c65 Use the 'target-features' and 'target-cpu' attributes to reset the subtarget features.
If two functions require different features (e.g., `-mno-sse' vs. `-msse') then
we want to honor that, especially during LTO. We can do that by resetting the
subtarget's features depending upon the 'target-feature' attribute.
