2010-07-27It's better to have the arrays, which would trigger the creation of stackBill Wendling
protectors, to be near the stack protectors on the stack. Accomplish this by tagging the stack object with a predicate that indicates that it would trigger this. In the prolog-epilog inserter, assign these objects to the stack after the stack protector but before the other objects. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@109481 91177308-0d34-0410-b5e6-96231b3b80d8

2010-05-14Rename "HasCalls" in MachineFrameInfo to "AdjustsStack" to better describe whatBill Wendling
the variable actually tracks. N.B., several back-ends are using "HasCalls" as being synonymous for something that adjusts the stack. This isn't 100% correct and should be looked into. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103802 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-13Teach MachineFrameInfo to track maximum alignment while stack objects are beingEvan Cheng
created. This ensures it's updated at all time. It means targets which perform dynamic stack alignment would know whether it is required and whether frame pointer register cannot be made available register allocation. This is a fix for rdar://7625239. Sorry, I can't create a reasonably sized test case. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96069 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-12Add a bool flag to StackObjects telling whether they reference spillDavid Greene
slots. The AsmPrinter will use this information to determine whether to print a spill/reload comment. Remove default argument values. It's too easy to pass a wrong argument value when multiple arguments have default values. Make everything explicit to trap bugs early. Update all targets to adhere to the new interfaces.. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@87022 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-25Update the description of MachineFrameInfo's OffsetAdjustment. The value ofBob Wilson
this adjustment does not change the direction or the signs of the object offsets, and the details of the offset calculations can be target-specific.

2008-11-06Implement the stack protector stack accesses via intrinsics:Bill Wendling
- stackprotector_prologue creates a stack object and stores the guard there. - stackprotector_epilogue reads the stack guard from the stack position created by stackprotector_prologue. - The PrologEpilogInserter was changed to make sure that the stack guard is first on the stack frame. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58791 91177308-0d34-0410-b5e6-96231b3b80d8
