2011-03-16The x86-64 ABI says that a bool is only guaranteed to be sign-extended to a byteCameron Zwarich
rather than an int. Thankfully, this only causes LLVM to miss optimizations, not generate incorrect code. This just fixes the zext at the return. We still insert an i32 ZextAssert when reading a function's arguments, but it is followed by a truncate and another i8 ZextAssert so it is not optimized. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127766 91177308-0d34-0410-b5e6-96231b3b80d8

2011-03-16Only convert allocas to scalars if it is profitable. The profitability metric ICameron Zwarich
chose is having a non-memcpy/memset use and being larger than any native integer type. Originally I chose having an access of a size smaller than the total size of the alloca, but this caused some minor issues on the spirit benchmark where SRoA runs again after some inlining. This fixes <rdar://problem/8613163>. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127718 91177308-0d34-0410-b5e6-96231b3b80d8

2011-03-15There were two issues fixed:Johnny Chen
1. The ARM Darwin *r9 call instructions were pseudo-ized recently. Modify the ARMDisassemblerCore.cpp file to accomodate the change. 2. The disassembler was unnecessarily adding 8 to the sign-extended imm24: imm32 = SignExtend(imm24:'00', 32); // A8.6.23 BL, BLX (immediate) // Encoding A1 It has no business doing such. Removed the offending logic. Add test cases to arm-tests.txt. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127707 91177308-0d34-0410-b5e6-96231b3b80d8

2011-03-15The VTBL (and VTBX) instructions are rather permissive concerning the masks theyBill Wendling
accept. If a value in the mask is out of range, it uses the value 0, for VTBL, or leaves the value unchanged, for VTBX. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127700 91177308-0d34-0410-b5e6-96231b3b80d8

defs. After live range splitting, an original value may be available in multiple registers. Tracing back through the registers containing the same value, find the best place to insert a spill, determine if the value has already been spilled, or discover a reaching def that may be rematerialized.

2011-03-15Add C++ global operator {new,new[],delete,delete[]}(unsigned {int,long}) to theNick Lewycky
memory builtins as equivalent to malloc/free. This is different from any attribute we have. For example, you can delete the allocators when their result is unused, but you can't collapse two calls to the same function, even if no global/memory state has changed in between. The noalias return states that the result does not alias any other pointer, but instcombine optimizes malloc() as though the result is non-null for the purpose of eliminating unused pointers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127673 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-15Add a peephole optimization to optimize pairs of bitcasts. e.g.Evan Cheng
v2 = bitcast v1 ... v3 = bitcast v2 ... = v3 => v2 = bitcast v1 ... = v1 if v1 and v3 are of in the same register class. bitcast between i32 and fp (and others) are often not nops since they are in different register classes. These bitcast instructions are often left because they are in different basic blocks and cannot be eliminated by dag combine. rdar://9104514 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127668 91177308-0d34-0410-b5e6-96231b3b80d8

2011-03-15There are some situations which can cause the URoR hack to infinitely recurseBill Wendling
and then go kablooie. The problem was that it was tracking the PHI nodes anew each time into this function. But it didn't need to. And because the recursion didn't know that a PHINode was visited before, it would go ahead and call itself. There is a testcase, but unfortunately it's too big to add. This problem will go away with the EH rewrite. <rdar://problem/8856298> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127640 91177308-0d34-0410-b5e6-96231b3b80d8
