7 years ago[PM] Remove the preverifier and directly compute the DominatorTree for
Chandler Carruth [Fri, 17 Jan 2014 10:56:02 +0000 (10:56 +0000)]
[PM] Remove the preverifier and directly compute the DominatorTree for
the verifier after ensuring the CFG is at least usefully formed.

This fixes a number of problems:
1) The PreVerifier was missing the controls the Verifier provides over
   *how* an invalid module is handled -- it just aborted the program!
   Now it uses the same logic as the Verifier which is significantly
   more library-friendly.
2) The DominatorTree used previously could have been cached and not
   updated due to bugs in prior passes and we would silently use the
   stale tree. This could cause dominance errors to not be as quickly
   diagnosed.
3) We can now (in the next patch) pull the functionality of the verifier
   apart from the pass infrastructure so that you can verify IR without
   having any form of pass manager. This in turn frees the code to share
   logic between old and new pass manager variants.

Along the way I fixed at least one annoying bug -- the state for
'Broken' wasn't being cleared from run to run causing all functions
visited after the first broken function to be marked as broken
regardless of whether *they* were a problem. Fortunately, I don't really
know much of a way to observe this peculiarity.

In case folks are worried about the runtime cost, its negligible.
I looked at running the entire regression test suite (which should be
a relatively good use of the verifier) before and after but was unable
to even measure the time spent on the verifier and there was no
regresion from before to after. I checked both with debug builds and
optimized builds.

Quentin Colombet [Thu, 16 Jan 2014 21:44:34 +0000 (21:44 +0000)]
[opt][PassInfo] Allow opt to run passes that need target machine.

When registering a pass, a pass can now specify a second construct that takes as
argument a pointer to TargetMachine.
The PassInfo class has been updated to reflect that possibility.
If such a constructor exists opt will use it instead of the default constructor
when instantiating the pass.

Since such IR passes are supposed to be rare, no specific support has been
added to this commit to allow an easy registration of such a pass.
In other words, for such pass, the initialization function has to be
hand-written (see CodeGenPrepare for instance).

Now, codegenprepare can be tested using opt:
opt -codegenprepare -mtriple=mytriple input.ll

7 years agoReMat: fix overly cavalier attitude to sub-register indices
Tim Northover [Thu, 16 Jan 2014 12:29:55 +0000 (12:29 +0000)]
ReMat: fix overly cavalier attitude to sub-register indices

There are two attempted optimisations in reMaterializeTrivialDef, trying to
avoid promoting the size of a register too much when rematerializing.
Unfortunately, both appear to be flawed. First, we see if the original register
would have worked, but this is inadequate. Consider:

    v1 = SOMETHING (v1 is QQ)
    v2:Q0 = COPY v1:Q1 (v1, v2 are QQ)
    ...
    uses of v2

In this case even though v2 *could* be used directly as the output of
SOMETHING, this would set the wrong bits of the QQ register involved. The
correct rematerialization must be:

    v2:Q0_Q1 = SOMETHING (v2 promoted to QQQ)
    ...
    uses of v2:Q1_Q2

For the second optimisation, if the correct remat is "v2:idx = SOMETHING" then
we can't necessarily expect v2 itself to be valid for SOMETHING, but we do try
to hunt for a class between v1 and v2 that works. Unfortunately, this is also
wrong:

    v1 = SOMETHING (v1 is QQ)
    v2:Q0_Q1 = COPY v1 (v1 is QQ, v2 is QQQ)
    ...
    uses of v2 as a QQQ

The canonical rematerialization here is "v2:Q0_Q1 = SOMETHING". However current
logic would decide that v2 could be a QQ (no interest is taken in later uses).

This patch, therefore, always accepts the widened register class without trying
to be clever. Generally there is no penalty to this (e.g. in the common GR32 <
GR64 case, expanding the width doesn't matter because it's not like you were
going to do anything else with the high bits of a GR32 register). It can
increase register pressure in cases like the ARM VFP regs though (multiple
non-overlapping but equivalent subregisters). This situation can be
spotted by the fact that both source and destination in the
not-quite-coalesced pair have a sub-register index and
rematerialisation is skipped in that situation.

Unfortunately, no in-tree targets actually expose this as far as I can tell
(there are so few isAsCheapAsAMove instructions for it to trigger on) so I've
been unable to produce a test. It was exposed in our ARM64 SPEC tests though,
and I will be adding a test there that we should be able to contribute
soon(TM).
