Dan Gohman 84117119ff Clang's #include handling apparently doesn't work for libstdc++'s 
fenv.h. See PR6907 for details. Work around this in FEnv.h to fix
the seflhost build.

This reverts commit 116234.

It compiled just fine with MSVC and clang...

Chris Lattner 1ef5e84c31 Per discussion with Sanjiv, remove the PIC16 target from mainline. When/if 
it comes back, it will be largely a rewrite, so keeping the old codebase
in tree isn't helping anyone.

Kenneth Uildriks b8d7efe785 Now using a variant of the existing inlining heuristics to decide whether to create a given specialization of a function in PartialSpecialization. If the total performance bonus across all callsites passing the same constant exceeds the specialization cost, we create the specialization.

Kenneth Uildriks 99463ca8cf Start separating out code metrics into code size metrics and code performance metrics. Partial Specialization will apply the former to function specializations, and the latter to all callsites that can use a specialization, in order to decide whether to create a specialization

 2010-10-08 03:16:56 +00:00
Jakob Stoklund Olesen 0f1677e190 After splitting, the remaining LiveInterval may be fragmented into multiple 
connected components. These components should be allocated different virtual
registers because there is no reason for them to be allocated together.

Add the ConnectedVNInfoEqClasses class to calculate the connected components,
and move values to new LiveIntervals.

Use it from SplitKit::rewrite by creating new virtual registers for the
components.

Owen Anderson 4698c5d7f7 Next step on the getting-rid-of-static-ctors train: begin adding per-library 
initialization functions that initialize the set of passes implemented in
that library.  Add C bindings for these functions as well.

Owen Anderson 5e19bfcde3 Move the pass initialization helper functions into the llvm namespace, and add 
a header declaring them all.  This is also where we will declare per-library pass-set
initializer functions down the road.

Chris Lattner bf7cffc730 add a common SDPatternOperator base class to SDNode and PatFrag for 
stuff that wants to take one or the other.  These can both be used
as the operation of a dag in a pattern match.

Jakob Stoklund Olesen 18842783cc Add MachineRegisterInfo::constrainRegClass and use it in MachineCSE. 
This function is intended to be used when inserting a machine instruction that
trivially restricts the legal registers, like LEA requiring a GR32_NOSP
argument.

Evan Cheng 49d4c0bd18 - Add TargetInstrInfo::getOperandLatency() to compute operand latencies. This 
allow target to correctly compute latency for cases where static scheduling
  itineraries isn't sufficient. e.g. variable_ops instructions such as
  ARM::ldm.
  This also allows target without scheduling itineraries to compute operand
  latencies. e.g. X86 can return (approximated) latencies for high latency
  instructions such as division.
- Compute operand latencies for those defined by load multiple instructions,
  e.g. ldm and those used by store multiple instructions, e.g. stm.

Bill Wendling 0198ce06fc Provide a fast "get me the target triple from the module" API. This can

Owen Anderson c25b39702f Another step towards getting rid of static ctors for pass registration: have INITIALIZE_PASS AND INITIALIZE_AG_PASS 
expand to an initializeMyPass() function (in additional to the extant static ctors).  Eventually, these will be called
from a big InitializeAllPasses() function, and the PassInfo's they create (which would be leaked if this code were used
at the moment) will be handed off to a PassRegistry for ownership.

Rafael Espindola bce26a1ee0 On ELF we need to know which symbols are used in relocations to decide if 
they should be in the symbol table or not. Instead of "guessing", just compute
the symbol table after the relocations are known.

Bill Wendling 402e54822b The pshufw instruction came about in MMX2 when SSE was introduced. Don't place 
it in with the SSSE3 instructions.

Steward! Could you place this chair by the aft sun deck? I'm trying to get away
from the Astors. They are such boors!

Kevin Enderby a68d004d88 Incorporate suggestions by Daniel Dunbar after his review. Thanks Daniel! 
1) Changed ValidateDwarfFileNumber() to isValidDwarfFileNumber() to be better
   named.  Since it is just a predicate and isn't actually changing any state.

2) Added a missing return in the comments for setCurrentDwarfLoc() in 
   include/llvm/MC/MCContext.h for fix formatting.

3) Changed clearDwarfLocSeen() to ClearDwarfLocSeen() since it does change
   state.

4) Simplified the last test in isValidDwarfFileNumber() to just a one line
   boolean test of MCDwarfFiles[FileNumber] != 0 for the final return statement.
