2012-12-06Modify the LLVM checkout of googletest:Alexey Samsonov
1) don't delete gtest-all.cc (which is used to gather all gtest source files in a single file) 2) make including LLVMSupport headers optional (on by default). Sanitizer tools may want to use their own versions of googletest compiled with specific flags, instead of the common googletest library used for all other LLVM/Clang unittests. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169559 91177308-0d34-0410-b5e6-96231b3b80d8

This is an alternative to the ImmutableMapRef interface where a factory should still be canonicalizing by default, but in certain cases an improvement can be made by delaying the canonicalization. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169532 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-06[msan] Do not store origin for clean values.Evgeniy Stepanov
Instead of unconditionally storing origin with every application store, only do this when the shadow of the stored value is != 0. This change also delays instrumentation of stores until after the walk over function's instructions, because adding new basic blocks confuses InstVisitor. We only keep 1 origin value per 4 bytes of application memory. This change fixes the bug when a store of a single clean byte wiped the origin for the whole 4-byte area. Since stores of uninitialized values are relatively uncommon, this change improves performance of track-origins mode by 5% median and by up to 47% on specs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169490 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-06Handle non-default array bounds.Bill Wendling
Some languages, e.g. Ada and Pascal, allow you to specify that the array bounds are different from the default (1 in these cases). If we have a lower bound that's non-default, then we emit the lower bound. We also calculate the correct upper bound in those cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169484 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-06Let targets provide hooks that compute known zero and ones for any_extendEvan Cheng
and extload's. If they are implemented as zero-extend, or implicitly zero-extend, then this can enable more demanded bits optimizations. e.g. define void @foo(i16* %ptr, i32 %a) nounwind { entry: %tmp1 = icmp ult i32 %a, 100 br i1 %tmp1, label %bb1, label %bb2 bb1: %tmp2 = load i16* %ptr, align 2 br label %bb2 bb2: %tmp3 = phi i16 [ 0, %entry ], [ %tmp2, %bb1 ] %cmp = icmp ult i16 %tmp3, 24 br i1 %cmp, label %bb3, label %exit bb3: call void @bar() nounwind br label %exit exit: ret void } This compiles to the followings before: push {lr} mov r2, #0 cmp r1, #99 bhi LBB0_2 @ BB#1: @ %bb1 ldrh r2, [r0] LBB0_2: @ %bb2 uxth r0, r2 cmp r0, #23 bhi LBB0_4 @ BB#3: @ %bb3 bl _bar LBB0_4: @ %exit pop {lr} bx lr The uxth is not needed since ldrh implicitly zero-extend the high bits. With this change it's eliminated. rdar://12771555 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169459 91177308-0d34-0410-b5e6-96231b3b80d8
