* llvm-ar: Let opening a directory failed in llvm-ar.NAKAMURA Takumi2013-11-08
| | | | | | | | Linux cannot open directories with open(2), although cygwin and *bsd can. Motivation: The test, Object/directory.ll, had been failing with --target=cygwin on Linux. XFAIL was improper for host issues. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194257 91177308-0d34-0410-b5e6-96231b3b80d8

* IR: Do not canonicalize constant GEPs into an out-of-bounds array accessDavid Majnemer2013-11-07
| | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Consider a GEP of: i8* getelementptr ({ [2 x i8], i32, i8, [3 x i8] }* @main.c, i32 0, i32 0, i64 0) If we proceeded to GEP the aforementioned object by 8, would form a GEP of: i8* getelementptr ({ [2 x i8], i32, i8, [3 x i8] }* @main.c, i32 0, i32 0, i64 8) Note that we would go through the first array member, causing an out-of-bounds accesses. This is problematic because we might get fooled if we are trying to evaluate loads using this GEP, for example, based off of an object with a constant initializer where the array is zero. This fixes PR17732.

* Rewrite SCEV's backedge taken count computation.Andrew Trick2013-11-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Patch by Michele Scandale! Rewrite of the functions used to compute the backedge taken count of a loop on LT and GT comparisons. I decided to split the handling of LT and GT cases becasue the trick "a > b == -a < -b" in some cases prevents the trip count computation due to the multiplication by -1 on the two operands of the comparison. This issue comes from the conservative computation of value range of SCEVs: taking the negative SCEV of an expression that have a small positive range (e.g. [0,31]), we would have a SCEV with a fullset as value range. Indeed, in the new rewritten function I tried to better handle the maximum backedge taken count computation when MAX/MIN expression are used to handle the cases where no entry guard is found. Some test have been modified in order to check the new value correctly (I manually check them and reasoning on possible overflow the new values seem correct). I finally added a new test case related to the multiplication by -1 issue on GT comparisons. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194116 91177308-0d34-0410-b5e6-96231b3b80d8
* Slightly change the way stackmap and patchpoint intrinsics are lowered.Andrew Trick2013-11-05
| | | | | | | | | | | | | | MorphNodeTo is not safe to call during DAG building. It eagerly deletes dependent DAG nodes which invalidates the NodeMap. We could expose a safe interface for morphing nodes, but I don't think it's worth it. Just create a new MachineNode and replaceAllUsesWith. My understaning of the SD design has been that we want to support early target opcode selection. That isn't very well supported, but generally works. It seems reasonable to rely on this feature even if it isn't widely used. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194102 91177308-0d34-0410-b5e6-96231b3b80d8

* [objc-arc] Convert the one directional retain/release relation assert to a ↵Michael Gottesman2013-11-05
| | | | | | | | | | | | | | | | | conditional check + fail. Due to the previously added overflow checks, we can have a retain/release relation that is one directional. This occurs specifically when we run into an additive overflow causing us to drop state in only one direction. If that occurs, we should bail and not optimize that retain/release instead of asserting. Apologies for the size of the testcase. It is necessary to cause the additive cfg overflow to trigger. rdar://15377890 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194083 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | | | | Submit the basic port of the rest of ARM constant islands code to Mips. Two test cases are added which reflect the next level of functionality: constants getting moved to water areas that are out of range from the initial placement at the end of the function and basic blocks being split to create water when none exists that can be used. There is a bunch of this code that is not complete and has been marked with IN_PROGRESS. I will finish cleaning this all up during the next week or two and submit the rest of the test cases. I have elminated some code for dealing with inline assembly because to me it unecessarily complicates things and some of the newer features of llvm like function attributies and builtin assembler give me better tools to solve the alignment issues created there. Also, for Mips16 I even have the option of not doing constant islands in the present of inline assembler if I chose. When everything has been completed I will summarize the port and notify people that are knowledgable regarding the ARM Constant Islands code so they can review it in it's entirety if they wish. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194053 91177308-0d34-0410-b5e6-96231b3b80d8

* AArch64: use default asm operand printing when modifier inapplicableTim Northover2013-11-04
| | | | | | | | | | | | If an inline assembly operand has multiple constraints (e.g. "Ir" for immediate or register) and an operand modifier (E.g. "w" for "print register as wN") then we need to decide behaviour when the modifier doesn't apply to the constraint. Previousely produced some combination of an assertion failure and a fatal error. GCC's behaviour appears to be to ignore the modifier and print the operand in the default way. This patch should implement that. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194024 91177308-0d34-0410-b5e6-96231b3b80d8
