First, avoid calling setTailCall(false) on musttail calls.  The funciton
prototypes should be "congruent", so the shadow layout should be exactly
the same.

Second, avoid inserting instrumentation after a musttail call to

7 years ago[MachineSink] Improve the compile time by preserving the dominance information
Quentin Colombet [Mon, 11 Aug 2014 23:52:01 +0000 (23:52 +0000)]
[MachineSink] Improve the compile time by preserving the dominance information
as long as possible.

** Context **

Each time the dominance information is modified, the dominator tree analysis
switches in a slow query mode. After a few queries without any modification on
the dominator tree, it performs an expensive update of its internal structure to
provide fast queries again.

** Problem **

Prior to this patch, the MachineSink pass was splitting the critical edges on
demand while relying heavy on the dominator tree information. In some cases,
this leads to pathological behavior where:
- We end up in the slow query mode right after splitting an edge.
- We update the dominance information.
- We break the dominance information again, thus ending up in the slow query
  mode and so on.

** Proposed Solution **

To mitigate this effect, this patch postpones all the splitting of the edges at
the end of each iteration of the main loop.
The benefits are:
- The dominance information is valid for the life time of an iteration.
- This simplifies the code as we do not have to special treat instructions that
  are sunk on critical edges. Indeed, the related block will be available
  through the next iteration.

The downside is that when edges splitting is required, this incurs an additional
iteration of the main loop compared to the previous scheme.

** Performance **

Thanks to this patch, the motivating example compiles in 6+ minutes instead of
10+ minutes. No test case added as the motivating example as nothing special but
being huge!

I have measured only noise for both the compile time and the runtime on the llvm
test-suite + SPECs with Os and O3.

Note: The current implementation of MachineBasicBlock::SplitCriticalEdge also
uses the dominance information and therefore, hits this problem. A subsequent
patch will address that.

ARM: try harder to detect non-IT eligible instructions

For many Thumb-1 register register instructions, setting the CPSR is not

The previous change to identify this scenario was insufficient as it did not

inspection of the ARMv6M ARM.

stringent checking of the MIs results in the If Conversion pass being prevented

ARM: correct isPredicable for MULS in ThHUMB mode

The ARM ARM states that CPSR may not be updated by a MUL in thumb mode.  Due to
an ordering of Thumb 2 Size Reduction and If Conversion, we would end up
generating a THUMB MULS inside an IT block.

The If Conversion pass uses the TTI isPredicable method to ensure that it can
transform a Basic Block.  However, because we only check for IT handling on
Thumb2 functions, we may miss some cases.  Even then, it only validates that the
CPSR is not *live* rather than it is not accessed.  This corrects the handling
for that particular case since the same restriction does not hold on the vast
majority of the instructions.

This does prevent the IfConversion optimization from kicking in in certain
cases, but generating correct code is more valuable.  Addresses PR20555.

R600/SI: Update concat_vectors.ll to check for scratch usage

These tests were using SI-NOT: MOVREL to make sure concat vectors
weren't being lowered to stack loads and stores, but we are using
scratch buffers for the stack now instead of registers, so we need
to add an additional SI-NOT check for scratch buffers.

With this change I was able to uncover one broken test which will
be fixed in a future commit.

[MCJIT] Simplify immediate decoding code in the RuntimeDyldMachO hierarchy.

Cleanup only: no functional change.

This patch makes RuntimeDyldMachO targets directly responsible for decoding
immediates, rather than letting them implement catch a callback from generic
code. Since this is a very target specific operation, it makes sense to let the
target-specific code drive it.
