70465616c2 Initialize the components of this class. Otherwise GCC thinks that Array may be
used uninitialized, since it fails to understand that Array is only used when
SingleValue is not, and outputs a warning.  It also seems generally safer given
that the constructor is non-trivial and has plenty of early exits.

e4957fb9b7 Add the heuristic to differentiate SSPStrong from SSPRequired.
The requirements of the strong heuristic are:

* A Protector is required for functions which contain an array, regardless of
  type or length.

* A Protector is required for functions which contain a structure/union which
  contains an array, regardless of type or length.  Note, there is no limit to
  the depth of nesting.

* A protector is required when the address of a local variable (i.e., stack
  based variable) is exposed. (E.g., such as through a local whose address is
  taken as part of the RHS of an assignment or a local whose address is taken as
  part of a function argument.)

114baee1fa Add the IR attribute 'sspstrong'.
SSPStrong applies a heuristic to insert stack protectors in these situations:

* A Protector is required for functions which contain an array, regardless of
  type or length.

* A Protector is required for functions which contain a structure/union which
  contains an array, regardless of type or length.  Note, there is no limit to
  the depth of nesting.

* A protector is required when the address of a local variable (i.e., stack
  based variable) is exposed. (E.g., such as through a local whose address is
  taken as part of the RHS of an assignment or a local whose address is taken as
  part of a function argument.)

This patch implements the SSPString attribute to be equivalent to
SSPRequired. This will change in a subsequent patch.

9f7818d9bd R600: rework handling of the constants
Remove Cxxx registers, add new special register - "ALU_CONST" and new
operand for each alu src - "sel". ALU_CONST is used to designate that the
new operand contains the value to override src.sel, src.kc_bank, src.chan
for constants in the driver.

Patch by: Vadim Girlin

Vincent Lejeune:
  - Use pointers for constants
  - Fold CONST_ADDRESS when possible

Tom Stellard:
  - Give CONSTANT_BUFFER_0 its own address space
  - Use integer types for constant loads

862d51fc67 [ObjCARC] Refactored out the inner most 2-loops from PerformCodePlacement into the method ConnectTDBUTraversals.
The method PerformCodePlacement was doing too much (i.e. 3x loops, lots of
different checking). This refactoring separates the analysis section of the
method into a separate function while leaving the actual code placement and
analysis preparation in PerformCodePlacement.

*NOTE* Really this part of ObjCARC should be refactored out of the main pass
class into its own seperate class/struct. But, it is not time to make that
change yet though (don't want to make such an invasive change without fixing all
of the bugs first).

the body does not use them and it appears the body has positional parameters.

This can cause unexpected results as in the added test case.  As the darwin

ignore the named parameters.  Now that we want to support both styles of
macros we issue a warning in this specific case.
