Matt Arsenault 8fac501602 Fix nondeterministic output in local stack slot alloc pass
This finds all of the references to a frame index in a function, and
sorts by the offset. If multiple instructions use the same offset,
nothing was breaking the tie for sorting.

This avoids the test failures the reverted r282999 introduced.

Pavel Labath 42eb6908e0 Don't set a software stepping breakpoint at 0 on arm or mips.
Summary:
Check whether the setting the breakpoint failed during instruction emulation. If
it did, the next pc is likely in unmapped memory, and the inferior will crash
anyway after the next instruction. Do not return an error in this case, but just
continue stepping.
Reenabled the crash during step test for android/linux.

Andrea Di Biagio 9bcb064f19 [IndVarSimplify][DebugLoc] When widening the exit loop condition, correctly reuse the debug location of the original comparison.
When the loop exit condition is canonicalized as a != compaison, reuse the
debug location of the original (non canonical) comparison.

Before this patch, the debug location of the new icmp was obtained from the
loop latch terminator. This patch fixes the issue by correctly setting the
IRBuilder's "current debug location" to the location of the original compare.

Vassil Vassilev e53a4b7402 [modules] PR28812: Modules can return duplicate field decls.
If two modules contain duplicate class definitions the lookup result can contain
more than 2 elements. Sift the lookup results until we find a field decl.

It is not necessary to do ODR checks in place as they done elsewhere.

This should fix issues when compiling with libstdc++ 5.2 and 6.2.

All values are returned by a method as size_t, and subsequently passed
to functions taking a size_t, or used where a size_t is also valid.
Better still, two loops (which had an unsigned), can be replaced by
a range-based for loop.

Vitaly Buka 64c80b4e39 [CodeGen] Don't emit lifetime intrinsics for some local variables
Summary:
Current generation of lifetime intrinsics does not handle cases like:

```
  {
    char x;
  l1:
    bar(&x, 1);
  }
  goto l1;

```
We will get code like this:

```
  %x = alloca i8, align 1
  call void @llvm.lifetime.start(i64 1, i8* nonnull %x)
  br label %l1
l1:
  %call = call i32 @bar(i8* nonnull %x, i32 1)
  call void @llvm.lifetime.end(i64 1, i8* nonnull %x)
  br label %l1
```

So the second time bar was called for x which is marked as dead.
Lifetime markers here are misleading so it's better to remove them at all.
This type of bypasses are rare, e.g. code detects just 8 functions building
clang (2329 targets).

Craig Topper 812d3d30ae [AVX-512] Add scalar vfmsub/vfnmsub mask3 intrinsics
Summary: Clang's intrinsic header currently tries to negate the third operand of a vfmadd mask3 in order to create vfmsub, but this fails isel. This patch adds scalar vfmsub and vfnmsub mask3 that we can use instead to avoid the negate. This is consistent with the packed instructions.

provision for supporting other supported platforms and formats later.

This is the first of a many-part change to fully implement the
`llvm-xray` tool.

We also define a subcommand registration and dispatch mechanism to be
used by other further subcommand implementations for llvm-xray.
