Argument. This is still an egregious hack since we don't have a nice interface for this kind of thing but should help the valgrind leak check buildbot to become green. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173267 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
2013-01-23R600: rework handling of the constantsTom Stellard
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.

2013-01-20Revert 172708.Nadav Rotem
The optimization handles esoteric cases but adds a lot of complexity both to the X86 backend and to other backends. This optimization disables an important canonicalization of chains of SEXT nodes and makes SEXT and ZEXT asymmetrical. Disabling the canonicalization of consecutive SEXT nodes into a single node disables other DAG optimizations that assume that there is only one SEXT node. The AVX mask optimizations is one example. Additionally this optimization does not update the cost model. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@172968 91177308-0d34-0410-b5e6-96231b3b80d8
