Micah Villmow 0242b9b543 Add in support for expansion of all of the comparison operations to the absolute minimum required set. This allows a backend to expand any arbitrary set of comparisons as long as a minimum set is supported.
The minimum set of required instructions is ISD::AND, ISD::OR, ISD::SETO(or ISD::SETOEQ) and ISD::SETUO(or ISD::SETUNE). Everything is expanded into one of two patterns:
Pattern 1: (LHS CC1 RHS) Opc (LHS CC2 RHS)
Pattern 2: (LHS CC1 LHS) Opc (RHS CC2 RHS)

Sean Silva fb509ed156 tblgen: Mechanically move dynamic_cast<> to dyn_cast<>.
Some of these dyn_cast<>'s would be better phrased as isa<> or cast<>.
That will happen in a future patch.

There are also two dyn_cast_or_null<>'s slipped in instead of
dyn_cast<>'s, since they were causing crashes with just dyn_cast<>.

Fariborz Jahanian 1c883b9b57 [Doc parsing] This patch searches overridden objc/c++
methods looking for documentation on a particular base
class inherited by any method that overrides the base class.
In case of redeclaration, as when objc method is defined
in the implementation, it also looks up for documentation
in class/class extension being redeclared.

Jim Ingham 4f465cff8a Change the Thread constructor over to take a Process& rather than a ProcessSP. We can't create Threads with a NULL ProcessSP, so it makes no sense to use the SP.
Then make the Thread a Broadcaster, and get it to broadcast when the selected frame is changed (but only from the Command Line) and when Thread::ReturnFromFrame 
changes the stack.
Made the Driver use this notification to print the new thread status rather than doing it in the command.
Fixed a few places where people were setting their broadcaster class by hand rather than using the static broadcaster class call.

Jordan Rose d8665b3d1a [analyzer] Don't run non-path-sensitive checks on system headers...
...but do run them on user headers.

Previously, we were inconsistent here: non-path-sensitive checks on code
/bodies/ were only run in the main source file, but checks on
/declarations/ were run in /all/ headers. Neither of those is the
behavior we want.

Thanks to Sujit for pointing this out!

Sean Silva 9ce5c06626 docs: Attempt to fix PR14053.
Hypothesis 1: use of `.. code::` directive instead of `.. code-block::`
is causing Sphinx to discard the block. On my machine, `.. code::`
renders fine. However, I don't think that `..  code::` is actually a
legit Sphinx directive. I believe that on my machine Sphinx is falling
back to just displaying it monospace with no syntax, whereas llvm.org's
Sphinx is just discarding it.

This is truly "remote debugging" since I can't reproduce this on my
machine. It would be helpful to be able to see the llvm.org Sphinx
build logs; if that's possible please let me know.

  ISD::FP_ROUND, rounding from v2f64 to v4f32 (after legalization from

Jordan Rose 2bd991a1c0 Move Sema::PropertyIfSetterOrGetter to ObjCMethodDecl::findPropertyDecl.
Then, switch users of PropertyIfSetterOrGetter and LookupPropertyDecl
(the latter by name) over to findPropertyDecl. This actually makes
-Wreceiver-is-weak a bit stronger than it was before.

Jordan Rose 79af985bad Change Sema::PropertyIfSetterOrGetter to make use of isPropertyAccessor.
Old algorithm:
1. See if the name looks like a getter or setter.
2. Use the name to look up a property in the current ObjCContainer
   and all its protocols.
3. If the current container is an interface, also look in all categories
   and superclasses (and superclass categories, and so on).

New algorithm:
1. See if the method is marked as a property accessor. If so, look through
   all properties in the current container and find one that has a matching
   selector.
2. Find all overrides of the method using ObjCMethodDecl's
   getOverriddenMethods. This collects methods in superclasses and protocols
   (as well as superclass categories, which isn't really necessary), and
   checks if THEY are accessors. This part is not done recursively, since
   getOverriddenMethods is already recursive.

This lets us handle getters and setters that do not match the property
names.

2012-10-10 16:42:38 +00:00
Jordan Rose d01e83ab3e Rename ObjCMethodDecl::isSynthesized to isPropertyAccessor.
This more accurately reflects its use: this flag is set when a method
matches the getter or setter name for a property in the same class,
and does not actually specify whether or not the definition of the method
will be synthesized (either implicitly or explicitly with @synthesize).

This renames the setter and backing field as well, and changes the
(soon-to-be-obsolete?) XML dump format to use 'property_accessor'
instead of 'synthesized'.

Michael Liao effae0c8e1 Add alternative support for FP_ROUND from v2f32 to v2f64
- Due to the current matching vector elements constraints in ISD::FP_EXTEND,
  rounding from v2f32 to v2f64 is scalarized. Add a customized v2f32 widening
  to convert it into a target-specific X86ISD::VFPEXT to work around this
  constraints. This patch also reverts a previous attempt to fix this issue by
  recovering the scalarized ISD::FP_EXTEND pattern and thus significantly
  reduces the overhead of supporting non-power-2 vector FP extend.

Stepan Dyatkovskiy 283baa0027 Fix for LDRB instruction:
SDNode for LDRB_POST_IMM is invalid: number of registers added to SDNode fewer
that described in .td.

7 ops is needed, but SDNode with only 6 is created.

In more details:
In ARMInstrInfo.td, in multiclass AI2_ldridx, in definition _POST_IMM, offset
operand is defined as am2offset_imm. am2offset_imm is complex parameter type,
and actually it consists from dummy register and imm itself. As I understood
trick with dummy reg was made for AsmParser. In ARMISelLowering.cpp, this dummy
register was not added to SDNode, and it cause crash in Peephole Optimizer pass.

The problem fixed by setting up additional dummy reg when emitting
LDRB_POST_IMM instruction.

Stepan Dyatkovskiy f13dbb8e24 Issue description:
SchedulerDAGInstrs::buildSchedGraph ignores dependencies between FixedStack
objects and byval parameters. So loading byval parameters from stack may be
inserted *before* it will be stored, since these operations are treated as
independent.

Fix:
Currently ARMTargetLowering::LowerFormalArguments saves byval registers with
FixedStack MachinePointerInfo. To fix the problem we need to store byval
registers with MachinePointerInfo referenced to first the "byval" parameter.

Also commit adds two new fields to the InputArg structure: Function's argument
index and InputArg's part offset in bytes relative to the start position of
Function's argument. E.g.: If function's argument is 128 bit width and it was
splitted onto 32 bit regs, then we got 4 InputArg structs with same arg index,
but different offset values.

Chandler Carruth a6399a519d Apply the same fundamental fix for PR14048 as was applied for PR11905.
The issue arises when coercing to/from types of different sizes. We need
to be certain that the allocation on either end has sufficient room for
the coerced type. When it doesn't, we need to make room, copy across,
and then proceed. PR11905 handled the case of storing function arguments
back into allocas in the function prolog, this patch handles the case of
setting up the function arguments in a call expression.

This is actually significantly simpler than the fix for PR11905. It ends
up being a trivial change to create a temporary alloca when the source
is too small and memcpy across. This should preserve the compile-time
fast-isel benefits of doing gep+load sequences and avoiding FCAs.

Reviewed by Benjamin and Evgeniy (who fixed PR11905).
