[clang-tidy/google-runtime-int] Allow passing non-bitwidth types to printf()-style APIs

Summary:
The `google-runtime-int` check currently fires on calls like:

  printf("%lu", (unsigned long)foo);

However, the style guide says:

> Where possible, avoid passing arguments of types specified by
> bitwidth typedefs to printf-based APIs.

http://google.github.io/styleguide/cppguide.html#64-bit_Portability

This diff relaxes the check to not fire on parameters to functions
with the `__format__` attribute. (I didn't specifically check
for `__printf__` since there are a few variations.)

We know if we go through the path L1 --> L3, %t6 should always be true. However
currently, if the rhs of the eq comparison is phi, JumpThreading fails to

The `applyUpdates` routine requires that updates are "balanced". This is

contract violation) goes wrong because we're never inserting and
removing the same edge. The implementation *happens* to do the right
thing to eliminate redundant insertions in that case.

[SystemZ] Do not use glue to represent condition code dependencies

Currently, an instruction setting the condition code is linked to

SelectionDAG.  This has a number of drawbacks; in particular, it
means the same CC cannot be used by multiple users.  It also makes
it more difficult to efficiently implement SADDO et. al.

This patch changes the back-end to represent CC dependencies as
normal values during SelectionDAG matching, along the lines of
how this is handled in the X86 back-end already.

In addition to the core mechanics of updating all relevant patterns,
this requires a number of additional changes:

- We now need to be able to spill/restore a CC value into a GPR
  if necessary.  This means providing a copyPhysReg implementation
  for moves involving CC, and defining getCrossCopyRegClass.

- Since we still prefer to avoid such spills, we provide an override
  for IsProfitableToFold to avoid creating a merged LOAD / ICMP if
  this would result in multiple users of the CC.

- combineCCMask no longer requires a single CC user, and no longer
  need to be careful about preventing invalid glue/chain cycles.

- emitSelect needs to be more careful in marking CC live-in to
  the basic block it generates.  Also, we can now optimize the
  case of multiple subsequent selects with the same condition
  just like X86 does.

6 years ago[BranchFolding] Salvage DBG_VALUE instructions from empty blocks
Bjorn Pettersson [Mon, 30 Apr 2018 14:37:46 +0000 (14:37 +0000)]
[BranchFolding] Salvage DBG_VALUE instructions from empty blocks

Summary:
This patch will introduce copying of DBG_VALUE instructions
from an otherwise empty basic block to predecessor/successor
blocks in case the empty block is eliminated/bypassed. It
is currently only done in one identified situation in the
BranchFolding pass, before optimizing on empty block.
It can be seen as a light variant of the propagation done
by the LiveDebugValues pass, which unfortunately is executed
after the BranchFolding pass.

We only propagate (copy) DBG_VALUE instructions in a limited
number of situations:
 a) If the empty BB is the only predecessor of a successor
    we can copy the DBG_VALUE instruction to the beginning of
    the successor (because the DBG_VALUE instruction is always
    part of the flow between the blocks).
 b) If the empty BB is the only successor of a predecessor
    we can copy the DBG_VALUE instruction to the end of the
    predecessor (because the DBG_VALUE instruction is always
    part of the flow between the blocks). In this case we add
    the DBG_VALUE just before the first terminator (assuming
    that the terminators do not impact the DBG_VALUE).

A future solution, to handle more situations, could perhaps
be to run the LiveDebugValues pass before branch folding?

This fix is related to PR37234. It is expected to resolve
the problem seen, when applied together with the fix in

6 years ago[SelectionDAG] Improve selection of DBG_VALUE using a PHI node result
Bjorn Pettersson [Mon, 30 Apr 2018 14:37:39 +0000 (14:37 +0000)]
[SelectionDAG] Improve selection of DBG_VALUE using a PHI node result

Summary:
When building the selection DAG at ISel all PHI nodes are
selected and lowered to Machine Instruction PHI nodes before
we start to create any SDNodes. So there are no SDNodes for
values produced by the PHI nodes.

In the past when selecting a dbg.value intrinsic that uses
the value produced by a PHI node we have been handling such
dbg.value intrinsics as "dangling debug info". I.e. we have
not created a SDDbgValue node directly, because there is
no existing SDNode for the PHI result, instead we deferred
the creationg of a SDDbgValue until we found the first use
of the PHI result.

The old solution had a couple of flaws. The position of the
selected DBG_VALUE instruction would end up quite late in a
basic block, and for example not directly after the PHI node
as in the LLVM IR input. And in case there were no use at all
in the basic block the dbg.value could be dropped completely.

This patch introduces a new VREG kind of SDDbgValue nodes.
It is similar to a SDNODE kind of node, but it refers directly
to a virtual register and not a SDNode. When we do selection
for a dbg.value that is using the result of a PHI node we
can do a lookup of the virtual register directly (as it already
is determined for the PHI node) and create a SDDbgValue node
immediately instead of delaying the selection until we find a
use.

This should fix a problem with losing debug info at ISel
as seen in PR37234 (https://bugs.llvm.org/show_bug.cgi?id=37234).
It does not resolve PR37234 completely, because the debug info
is dropped later on in the BranchFolder (see D46184).
