2013-01-24The next phase of Mips16 hard float implementation.Reed Kotler
Allow Mips16 routines to call Mips32 routines that have abi requirements that either arguments or return values are passed in floating point registers. This handles only the pic case. We have not done non pic for Mips16 yet in any form. The libm functions are Mips32, so with this addition we have a complete Mips16 hard float implementation. We still are not able to complete mix Mip16 and Mips32 with hard float. That will be the next phase which will have several steps. For Mips32 to freely call Mips16 some stub functions must be created. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173320 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-24Create a new class: AttributeSetNode.Bill Wendling

2013-01-23Add the heuristic to differentiate SSPStrong from SSPRequired.Bill Wendling
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.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173231 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-23Add the IR attribute 'sspstrong'.Bill Wendling
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173230 91177308-0d34-0410-b5e6-96231b3b80d8

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.
