2012-07-16Doubleword Shift Left Logical Plus 32Jack Carter
Mips shift instructions DSLL, DSRL and DSRA are transformed into DSLL32, DSRL32 and DSRA32 respectively if the shift amount is between 32 and 63 Here is a description of DSLL: Purpose: Doubleword Shift Left Logical Plus 32 To execute a left-shift of a doubleword by a fixed amount--32 to 63 bits Description: GPR[rd] <- GPR[rt] << (sa+32) The 64-bit doubleword contents of GPR rt are shifted left, inserting zeros into the emptied bits; the result is placed in GPR rd. The bit-shift amount in the range 0 to 31 is specified by sa. This patch implements the direct object output of these instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160277 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-16Fix a bug in the 3-address conversion of LEA when one of the operands is anNadav Rotem
undef virtual register. The problem is that ProcessImplicitDefs removes the definition of the register and marks all uses as undef. If we lose the undef marker then we get a register which has no def, is not marked as undef. The live interval analysis does not collect information for these virtual registers and we crash in later passes. Together with Michael Kuperstein <michael.m.kuperstein@intel.com> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160260 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-16Revert r160254 temporarily.Chandler Carruth
It turns out that ASan relied on the at-the-end block insertion order to (purely by happenstance) disable some LLVM optimizations, which in turn start firing when the ordering is made more "normal". These optimizations in turn merge many of the instrumentation reporting calls which breaks the return address based error reporting in ASan. We're looking at several different options for fixing this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160256 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-16Teach AddressSanitizer to create basic blocks in a more natural order.Chandler Carruth
This is particularly useful to the backend code generators which try to process things in the incoming function order. Also, cleanup some uses of IRBuilder to be a bit simpler and more clear. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160254 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-16Add a basic test for AddressSanitizer. This is just a bare-bonesChandler Carruth
functionality test. In general, unless the functionality is substantially separated, we should lump more basic testing into this file.

2012-07-16Add support for attaching branch weight metadata directly from the IRBuilder.Chandler Carruth
Added a basic unit test for this with CreateCondBr. I didn't go all the way and test the switch side as the boilerplate for setting up the switch IRBuilder unit tests is a lot more. Fortunately, the two share all the interesting code paths. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160251 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-16This CL changes the function prologue and epilogue emitted on X86 when stack ↵Alexey Samsonov
needs realignment. It is intended to fix PR11468. Old prologue and epilogue looked like this: push %rbp mov %rsp, %rbp and $alignment, %rsp push %r14 push %r15 ... pop %r15 pop %r14 mov %rbp, %rsp pop %rbp The problem was to reference the locations of callee-saved registers in exception handling: locations of callee-saved had to be re-calculated regarding the stack alignment operation. It would take some effort to implement this in LLVM, as currently MachineLocation can only have the form "Register + Offset". Funciton prologue and epilogue are now changed to: push %rbp mov %rsp, %rbp push %14 push %15 and $alignment, %rsp ... lea -$size_of_saved_registers(%rbp), %rsp pop %r15 pop %r14 pop %rbp Reviewed by Chad Rosier. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160248 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-15Move llvm/Support/TypeBuilder.h -> llvm/TypeBuilder.h. This completesChandler Carruth
the move of *Builder classes into the Core library. No uses of this builder in Clang or DragonEgg I could find. If there is a desire to have an IR-building-support library that contains all of these builders, that can be easily added, but currently it seems likely that these add no real overhead to VMCore. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160243 91177308-0d34-0410-b5e6-96231b3b80d8

Add a micro-optimization to getNode of CONCAT_VECTORS when both operands are undefs.

Together with Michael Kuperstein <michael.m.kuperstein@intel.com> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160229 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-15Reapply r160194, switching to use LV information for finding local kills.Chandler Carruth
The notable fix is to look at any dependencies attached to the kill instruction (or other instructions between MI nad the kill) where the dependencies are specific to the register in question. The old code implicitly handled this by rejecting the transform if *any* other uses were found within the block, but after the start point. The new code directly finds the kill, and has to re-use the existing dependency scan to check for non-kill uses. This was caught by self-host, but I found the bug via inspection and use of absurd assert scaffolding to compute the kills in two ways and compare them. So I have no useful testcase for this other than "bootstrap". I'd work harder to reduce a test case if this particular code were likely to live for a long time. Thanks to Benjamin Kramer for reviewing the fix itself. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160228 91177308-0d34-0410-b5e6-96231b3b80d8

This allows SCEVExpander to run on the IV expressions. This codifies an assumption made by LSR to complete the fix for PR11356, but I haven't been able to generate a separate unit test for this part. I'm adding it as an extra safety check. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160204 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-13This is one of the first steps at moving to replace target-dependent Joel Jones
intrinsics with target-indepdent intrinsics. The first instruction(s) to be handled are the vector versions of count leading zeros (ctlz). The changes here are to clang so that it generates a target independent vector ctlz when it sees an ARM dependent vector ctlz. The changes in llvm are to match the target independent vector ctlz and in VMCore/AutoUpgrade.cpp to update any existing bc files containing ARM dependent vector ctlzs with target-independent ctlzs. There are also changes to an existing test case in llvm for ARM vector count instructions and a new test for the bitcode upgrade. <rdar://problem/11831778> There is deliberately no test for the change to clang, as so far as I know, no consensus has been reached regarding how to test neon instructions in clang; q.v. <rdar://problem/8762292> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160200 91177308-0d34-0410-b5e6-96231b3b80d8
