Ulrich Weigand cdce026b4d [SystemZ] Avoid LER on z13 due to partial register dependencies
On the z13, it turns out to be more efficient to access a full
floating-point register than just the upper half (as done e.g.
by the LE and LER instructions).

Current code already takes this into account when loading from
memory by using the LDE instruction in place of LE.  However,
we still generate LER, which shows the same performance issues
as LE in certain circumstances.

This patch changes the back-end to emit LDR instead of LER to
implement FP32 register-to-register copies on z13.

Benjamin Kramer 12f2de1a1f [Frontend] Disable value name discarding for all sanitizers.
ASan also relies on names on allocas and will emit unhelpful output if
they're not present. Just force-enable value names for now. Should
unbreak release builds of asan.

Haojian Wu e641cb4807 [clang-tidy] Fix "Name is not a simple identifier" assertion in `modernize-loop-convert` check.
Summary:
Fix assertion failure: "Name is not a simple identifier".

`Decl::GetName` assumes the name should be an identifier. When the check
processes the function calling statement with speciail key name like
'it.operator->()', it will trigger the assert in `GetName`.

Rather than using `Decl::GetName`, we use `getNameAsString` which works
with special key names in C++.

Daniel Sanders cfa3483c8e [mips] Simplify ordering of range checked immediate classes.
Summary:
With the addition of checks to ensure that operands have a strict ordering
it has become tricky to manage the order in the way I originally intended.

This patch linearizes the ordering which simplifies the implementation but
requires an order that is arbitrary in places. Here are some examples:
* uimm4 < uimm5 < uimm6
* simm4 < uimm4 < simm5 < uimm5
* uimm5 < uimm5_plus1 (1..32) < uimm5_plus32 (32..63) < uimm6
  The term 'superset' starts to break down here since the *_plus* classes
  are not true supersets of uimm5 (but they are still subsets of uimm6).
* uimm5 < uimm5_64, and uimm5 < vsplat_uimm5
  This is entirely arbitrary. We need an ordering and what we pick is
  unimportant since only one is possible for a given mnemonic.

Haicheng Wu d60ae33d29 [CVP] Convert an SDiv to a UDiv if both operands are known to be nonnegative
The motivating example is this

for (j = n; j > 1; j = i) {
   i = j / 2;
}

The signed division is safely to be changed to an unsigned division (j is known
to be larger than 1 from the loop guard) and later turned into a single shift
without considering the sign bit.
