Dan Gohman 0b3bcee284 Rename AliasSet to SubRegs, to reflect changes in the surrounding code.

Dan Gohman 6613991eae Move the include of MachineLocation.h into MachineModuleInfo.h
because it declares a std::vector<MachineMove>, and strict
concept checking requires the definition of MachineMove to be
available.

Dan Gohman bf293c48db Fix a subtle bug in DeadMachineInstructionElim's liveness
computation. A def of a register doesn't necessarily kill
live super-registers.

Dan Gohman 4459c4250d Adjust whitespace in debug messages to be more consistent
with other debug messages.

Evan Cheng 3b0f5e4d61 - Add target lowering hooks that specify which setcc conditions are illegal,
i.e. conditions that cannot be checked with a single instruction. For example,
SETONE and SETUEQ on x86.
- Teach legalizer to implement *illegal* setcc as a and / or of a number of
legal setcc nodes. For now, only implement FP conditions. e.g. SETONE is
implemented as SETO & SETNE, SETUEQ is SETUO | SETEQ.
- Move x86 target over.

Dan Gohman e7ced74558 FastISel support for exception-handling constructs.
- Move the EH landing-pad code and adjust it so that it works
   with FastISel as well as with SDISel.
 - Add FastISel support for @llvm.eh.exception and
   @llvm.eh.selector.

Dan Gohman 9c4b7d5c4f Fix command-line option printing to print two spaces where needed,
instead of requiring all "short description" strings to begin with
two spaces. This makes these strings less mysterious, and it fixes
some cases where short description strings mistakenly did not
begin with two spaces.

Matthijs Kooijman 43686a6665 * Make TargetLowering not crash when TargetMachine::getTargetAsmInfo() returns
null. This assumes that any target that does not have AsmInfo, does not
   support "LocAndDot".

Chris Lattner 2753955fc0 Change CALLSEQ_BEGIN and CALLSEQ_END to take TargetConstant's as
parameters instead of raw Constants.  This prevents the constants from
being selected by the isel pass, fixing PR2735.

Dan Gohman 60ad173dfe Remove -disable-fast-isel. Use cl::boolOrDefault with -fast-isel
instead.

So now: -fast-isel or -fast-isel=true enable fast-isel, and
-fast-isel=false disables it. Fast-isel is also on by default
with -fast, and off by default otherwise.

Dan Gohman c1d47c56f9 Avoid emitting redundant materializations of integer constants
for things like null pointers, which at this level aren't
different from regular integer constants.

Dan Gohman 13b048268b Fix fast-isel's handling of atomic instructions. They may
expand to multiple basic blocks, in which case fast-isel
needs to informed of which block to use as it resumes
inserting instructions.

Dan Gohman 78bb44fcd4 Fix a bug in the local allocator's liveness computation where it
was setting kill flags on tied uses in two-address instructions.
The kill flags were causing the allocator to think it could
allocate the use and its tied def in different registers.

Dale Johannesen 5d60c1ebb1 Pass MemOperand through for 64-bit atomics on 32-bit,

Duncan Sands 6e42742d2d The result of getSetCCResultType (eg: i32) may be larger
than the type an i1 is promoted to (eg: i8).  Account
for this.  Noticed by Tilmann Scheller on CellSPU; he
will hopefully take care of fixing this in LegalizeDAG
and adding a testcase!

Dan Gohman 4e072a75cc Implement fast-isel support for zero-extending from i1.
It turns out that this is a fairly common operation,
and it's easy enough to handle.

Dan Gohman 1ab1d31f7a Optimize conditional branches in X86FastISel. This replaces

with this:
