Fix PR8445: a block with no predecessors may be the entry block, in which case
...
it isn't unreachable and should not be zapped. The check for the entry block
was missing in one case: a block containing a unwind instruction. While there,
do some small cleanups: "M" is not a great name for a Function* (it would be
more appropriate for a Module*), change it to "Fn"; use Fn in more places.

Properly model the latency of register defs which are 1) function returns or

2) live-outs.
Previously the post-RA schedulers completely ignore these dependencies since
returns, branches, etc. are all scheduling barriers. This patch model the

handle calls by marking their register uses.

This is a prototype of an experimental register allocation
...
framework. It's purpose is not to improve register allocation per se,
but to make it easier to develop powerful live range splitting. I call
it the basic allocator because it is as simple as a global allocator
can be but provides the building blocks for sophisticated register
allocation with live range splitting.
A minimal implementation is provided that trivially spills whenever it
runs out of registers. I'm checking in now to get high-level design
and style feedback. I've only done minimal testing. The next step is
implementing a "greedy" allocation algorithm that does some register
reassignment and makes better splitting decisions.

Be more strict about detecting multi-use blocks for isolation.
...
When a block has exactly two uses and the register is both live-in and live-out,
don't isolate the block. We would be inserting two copies, so we haven't really
made any progress.
If the live-in and live-out values separate into disconnected components after
splitting, we would be making progress. We can't detect that for now.

half of the Q register), rather than with just regno. This allows us to unify the encodings for

Adding initial AsmParser implementation for the MBlaze backend. It is
...
mostly based on the ARM AsmParser at this time and is not particularly
functional.
Changed the MBlaze data layout from:
"E-p:32:32-i8:8:8-i16:16:16-i64:32:32-f64:32:32-v64:32:32-v128:32:32-n32"
to:
"E-p:32:32:32-i8:8:8-i16:16:16"
because the MicroBlaze doesn't have i64, f64, v64, or v128 data types.
Cleaned up the MBlaze source code:
1. The floating point register class has been removed. The
MicroBlaze does not have floating point registers. Floating
point values are simply stored in integer registers.
2. Renaming the CPURegs register class to GPR to reflect the
standard naming.
3. Removing a lot of stale code from AsmPrinter after
the conversion to InstPrinter.
4. Simplified sign extended loads by marking them as
expanded in ISelLowering.

More tweaks to X86 instructions to allow the 'w' suffix in places it makes

sense, when the instruction takes the 16-bit ax register or m16 memory
location. These changes to llvm-mc matches what the darwin assembler allows
for these instructions. Also added the missing flex (without the wait prefix)
and ud2a as an alias to ud2 (still to add ud2b).

Major update of the MicroBlaze backend. The new features are:
...
1. A delay slot filler that searches for valid instructions
to fill the delay slot with. Previously NOPs would always
be inserted into delay slots.
2. Support for MC based instruction printer added.
3. Support for MC based machine code generation and ELF
file generation. ELF file generation does not yet
completely work as much of the ELF support infrastructure
is still x86/x86-64 specific.
4. General clean up of the MBlaze backend code. Much of the
tablegen code has been cleanup and simplified.
Bug Fixes:
1. Removed duplicate periods from subtarget feature descriptions.
2. Many of the instructions had bad machine code information
in the tablegen files. Much of this has been fixed.

More accurate estimate / tracking of register pressure.
...
- Initial register pressure in the loop should be all the live defs into the
loop. Not just those from loop preheader which is often empty.
- When an instruction is hoisted, update register pressure from loop preheader
to the original BB.
- Treat only use of a virtual register as kill since the code is still SSA.

Shrink MachineOperand from 40 to 32 bytes on 64-bit hosts.

Pull an unsigned out of the Contents union such that it has the same size as two
pointers and no padding.
Arrange members such that the Contents union and all pointers can be 8-byte
aligned without padding.
This speeds up code generation by 0.8% on a 64-bit host. 32-bit hosts should be
unaffected.

Get rid of static constructors for pass registration. Instead, every pass exposes an initializeMyPassFunction(), which
...
must be called in the pass's constructor. This function uses static dependency declarations to recursively initialize
the pass's dependencies.
Clients that only create passes through the createFooPass() APIs will require no changes. Clients that want to use the
CommandLine options for passes will need to manually call the appropriate initialization functions in PassInitialization.h
before parsing commandline arguments.
I have tested this with all standard configurations of clang and llvm-gcc on Darwin. It is possible that there are problems
with the static dependencies that will only be visible with non-standard options. If you encounter any crash in pass
registration/creation, please send the testcase to me directly.

- Add a hook for target to determine whether an instruction def is
...
"long latency" enough to hoist even if it may increase spilling. Reloading
a value from spill slot is often cheaper than performing an expensive
computation in the loop. For X86, that means machine LICM will hoist
SQRT, DIV, etc. ARM will be somewhat aggressive with VFP and NEON
instructions.
- Enable register pressure aware machine LICM by default.

Add support for vmov.f64/.f32 encoding. There's a bit of a hack going on
...
here. The f32 in FCONSTS is handled as a double instead of a float in the
code. So the encoding of the immediate into the instruction isn't exactly in
line with the documentation in that regard. But given that we know it's handled
as a double, it doesn't cause any harm.

PR8359: The ARM backend may end up allocating registers D16 to D31 when
...
"-mattr=+vfp3" is specified. However, this will not work for hardware that
only supports 16 registers. Add a new flag to support -"mattr=+vfp3,+d16".

LocalRewriter.
This is a bit of a hack that adds an implicit use operand to model the

separate passes, and a single operand would never be processed twice.

Extract method ProcessUses from LocalRewriter::RewriteMBB. Both parent and child
...
are still way too long, but it's a start.
No functional change intended.

Do not check that the bodies of two defs of same linkonce global are the same.
...
Such a check does not make any sense in presense of inlining and other compiler-dependent stuff.
This should fix bunch of warnings on mingw32.

Implement a few more binary encoding bits. Still very early stage proof-of-
...
concept level stuff at this point, but it is generally working for those
instructions that know how to map the operands.
This patch fills in the register operands for add/sub/or/etc instructions
and adds the conditional execution predicate encoding.

Filter out illegal formulae after updating offsets, not before, so that
...
formulae which become illegal as a result of the offset updating don't
escape.
This is for rdar://8529692. No testcase yet, because the given cases
hit use-list ordering differences.
