* Add the heuristic to differentiate SSPStrong from SSPRequired.Bill Wendling2013-01-233-38/+2635
| | | | | | | | | | | | | | | | | | 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.) llvm-svn: 173231
* Add the IR attribute 'sspstrong'.Bill Wendling2013-01-2314-44/+856
| | | | | | | | | | | | | | | | | | | | | 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. llvm-svn: 173230

| | | | | | | | | | | | | | | | | | | | 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.

* [ObjCARC] Refactored out the inner most 2-loops from PerformCodePlacement ↵Michael Gottesman2013-01-221-153/+198
| | | | | | | | | | | | | | | | 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). llvm-svn: 173201

* Begin fleshing out an interface in TTI for modelling the costs ofChandler Carruth2013-01-225-66/+225
| | | | | | | | | | | | | | | | | | | | | | | | | | | generic function calls and intrinsics. This is somewhat overlapping with an existing intrinsic cost method, but that one seems targetted at vector intrinsics. I'll merge them or separate their names and use cases in a separate commit. This sinks the test of 'callIsSmall' down into TTI where targets can control it. The whole thing feels very hack-ish to me though. I've left a FIXME comment about the fundamental design problem this presents. It isn't yet clear to me what the users of this function *really* care about. I'll have to do more analysis to figure that out. Putting this here at least provides it access to proper analysis pass tools and other such. It also allows us to more cleanly implement the baseline cost interfaces in TTI. With this commit, it is now theoretically possible to simplify much of the inline cost analysis's handling of calls by calling through to this interface. That conversion will have to happen in subsequent commits as it requires more extensive restructuring of the inline cost analysis. The CodeMetrics class is now really only in the business of running over a block of code and aggregating the metrics on that block of code, with the actual cost evaluation done entirely in terms of TTI. llvm-svn: 173148
