With the RCInfo data, the new register class definition would be
something like
class MyRegisterClass : RegisterClass<...> {
let RCInfos = HwModeSelect<[Is32Bit, Is64Bit, Is128Bit],
[RCInfo32, RCInfo64, RCInfo128]>;
}
In either case, aggregating the info in a RCInfo class would require
additional changes in TableGen so that it picks up the
size/alignment/type data from the RCInfos list, instead of fro...

RFC: Implement variable-sized register classes
...le instructions with the
same encoding. Without a workaround, an assert is tripped in
llvm-tblgen when trying to produce a StringSwitch for
MatchRegisterName. The solution in Mips, PPC and others seems to be
involve the generation of MatchRegisterName. What has been discussed
so far with regards to HwMode and variable-size register classes
points to a solution, but I don't think it's quite enough. Options
include:
1. Only have one set of register definitions, and have the variable
sized register class determine the bit width. The problem is there are
often some instructions where I think yo...

RFC: Implement variable-sized register classes
...ableGen would need to be aware of the association
between value types and hardware modes. The rest of this proposal
describes the programming interface to provide necessary information to
TableGen.
1. Define a mode class. It will be recognized by TableGen as having a
special meaning.
class HwMode<list<Predicate> Ps> {
// List of Predicate objects that determine whether this mode
// applies. This is used for situation where the code generated by
// TableGen needs to determine this, as opposed to TableGen itself,
// for example in the isel pattern-matching code...

[PATCH v2 00/21] drm: Clean up VBLANK callbacks in struct drm_driver
VBLANK handlers in struct drm_driver are deprecated. Only legacy,
non-KMS drivers are supposed to used them. DRM drivers with kernel
modesetting are supposed to use VBLANK callbacks of the CRTC
infrastructure.
This patchset converts all DRM drivers to CRTC VBLANK callbacks and
cleans up struct drm_driver. The remaining VBLANK callbacks in struct
drm_driver are only used by legacy drivers.

Work on DAG Isel for TableGen and compiler
Given that I'm only somewhat up-to-speed on the DAG ISel scheme and not much at all on the Global ISel scheme, I'm tempted to work on the former and then the latter. So I'll look at the CodeGenDAGPatterns messages first. Then I will take a look at Global ISel.
Matt: Can you suggest one or two things about Global ISel that could use some work? I won't get to it quickly, but it will
