Before accessing a node as a ConstandSDNode, make sure it actually is one. No testcase of non-trivial size. rdar://11948669 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160735 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-25Don't perform an overaligned load in this test, since that's undefinedDuncan Sands
behaviour that might be exploited one day. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160714 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-25When folding a load from a global constant, if the load started in the middleDuncan Sands
of an array element (rather than at the beginning of the element) and extended into the next element, then the load from the second element was being handled wrong due to incorrect updating of the notion of which byte to load next. This fixes PR13442. Thanks to Chris Smowton for reporting the problem, analyzing it and providing a fix. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160711 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-25Eliminate the stack slot used to save the global base register.Akira Hatanaka
The long branch pass (fixed in r160601) no longer uses the global base register to compute addresses of branch destinations, so it is not necessary to reserve a slot on the stack. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160703 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-24In order to correctly compileRafael Espindola
struct s { double x1; float x2; }; __attribute__((regparm(3))) struct s f(int a, int b, int c); void g(void) { f(41, 42, 43); } We need to be able to represent passing the address of s to f (sret) in a register (inreg). Turns out that all that is needed is to not mark them as mutually incompatible. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160695 91177308-0d34-0410-b5e6-96231b3b80d8
