Felipe de Azevedo Piovezan [Fri, 10 Mar 2023 03:22:50 +0000 (22:22 -0500)]
[MachineCombiner] Preserve debug instruction number

Each target's `TargetInstrInfo` is responsible for announcing which code
patterns it is able to transform during the MachineCombiner pass.
Currently, these patterns are applied without preserving the debug
instruction number required by the InstrRef implementation of
LiveDebugValues. As such, we've seen a number of examples where debug
information is dropped for variables in InstrRef mode that were
otherwise available in VarLoc mode. This has been observed both in X86
and AArch examples.

This commit is an initial attempt at preserving said numbers by changing
the general (target agnostic) implementation of TargetInstrInfo: the
reassociation pattern must keep the debug number of the "top level"
instruction, i.e., the instruction whose value represents the final
value of the arithmetic expression. Intermediate values must have their
debug number dropped, as they have no equivalent value in the
unoptimized code.

Future work is required to update each target's
`TargetInstrInfo::genAlternativeCodeSequence` method.

[LLD] Increase thunk pass limit

In issue 61250 https://github.com/llvm/llvm-project/issues/61250 there is
an example of a program that takes 17 passes to converge, which is 2 more
than the current limit of 15. Analysis of the program shows a particular
section that is made up of many roughly thunk sized chunks of code ending
in a call to a symbol that needs a thunk. Due to the positioning of the
section, at each pass a subset of the calls go out of range of their
original thunk, needing a new one created, which then pushes more thunks
out of range. This process eventually stops after 17 passes.

This patch is the simplest fix for the problem, which is to increase
the pass limit. I've chosen to double it which should comfortably
account for future cases like this, while only taking a few more
seconds to reach the limit in case of non-convergence.

As discussed in the issue, there could be some additional work done
to limit thunk reuse, this would potentially increase the number of
thunks in the program but should speed up convergence.

1. After dynamic relocations and functions were read search for dynamic
relocations located in functions. Currently we expected them only to be
relative and only to be in constant island. Mark islands of such
functions to have dynamic relocations and create CI access symbol on the
relocation offset, so the BD would be created for such place.
2. During function disassemble and handling address reference for
constant island check if the referred external CI has dynamic
relocation. And if it has one we would continue to refer original CI
rather then creating a local copy.
3. After function disassembly stage mark function that has dynamic reloc
in CI as non-simple. We don't want such functions to be optimized, since
such passes as split function would create 2 copies of CI which we
unable to support currently.
4. During updating output values for BF search for BD located in CI and
update their output locations.
5. On dynamic relocation patching stage search for binary data located
on relocation offset. If it was moved use new relocation offset value
rather then an old one.

[InstCombine] use loop info when running the pass after loop vectorization

This is the follow-up to D144199 and suggestion from D144045.
We make use of loop info explicit via InstCombine pass parameter
rather than semi-arbitrary via caching.

The only InstCombine transform that uses LoopInfo currently is a
GEP fold in visitGEPOfGEP(), so that shows up as a failure in the
dedicated test for the fold as well as several LoopVectorizer tests
that run extra passes.

I don't see any pass manager regression tests that actually check
for pass options, but this is intended to be NFC for the pass
pipeline behavior - we only try to use loop info where it would
have been used before via caching .

[mlir][core] Fix inline pass default pipeline dump

The inliner pass performs canonicalization when created programtically, run with `mlir-opt` with default options, or when explicitly specified. However, when running the pipeline resulting from a `-dump-pass-pipeline` on a default inline pass, the canonicalization is not performed as part of the inlining. This is because the default value for the `default-pipeline` option of the inline pass is an empty string, and this is selected during the dumping. When `InlinerPass::initializeOptions` detects the empty string, it sets the `defaultPipeline` to `nullptr`, which was previously set to canonicalize in the `InlinerPass` constructor, thus the canonicalization is not performed.

The added test checks if the inline pass performs canonicalization by default, and that the dumped `default-pipeline` is set to `canonicalize`.

[libc] update LibcTableGenUtil for LLVM_LINK_LLVM_DYLIB

DISABLE_LLVM_LINK_LLVM_DYLIB.  This option avoids linking with
libLLVM.so when LLVM_LINK_LLVM_DYLIB is specified.  Unfortunately,
this can cause wierd linkage errors where symbols are defined
multiple times, with one definition coming from static linkage
and another definition coming from libLLVM.so.  This is usually
apparent as a link error with options defined multiple times.

This patch adds DISABLE_LLVM_LINK_LLVM_DYLIB to this library, to
get consistent linkage of libc-hdrgen.
