We can improve this check and reduce the number of copies in GISel-compiled code

- onlyDefinesFP

When function signatures don't match and the undefined function is not
called directly (i.e. only has its address taken) we don't issue a
warning or create a runtime thunk for the undefined function.

Instead in this case we simply use the defined version of the function.
This is possible since checking signatures of dynamic calls happens
at runtime so any invalid usage will still result in a runtime error.

This is needed to allow C++ programs to link without generating
warnings.  Its not uncommon in C++ for vtables to be populated by
function address whee the signature of the function is not known in the

[GlobalISel][AArch64] Improve register bank mappings for G_SELECT

The fcsel and csel instructions differ in only the register banks they work on.

So, they're entirely interchangeable otherwise.

With this in mind, this does two things:

- Teach AArch64RegisterBankInfo to consider the inputs to G_SELECT as well as
  the outputs.
- Teach it to choose the best register bank mapping based off the constraints
  of the inputs and outputs.

The "best" in this case means the one that requires the smallest number of
copies to properly emit a fcsel/csel.

For example, if the inputs are all already going to be on FPRs, we should
emit a fcsel, even if the output is a GPR. This costs one copy to produce the
result, but saves us from copying the inputs into GPRs.

select instruction.

[AArch64][SVE2] Asm: fix overlapping bit

Summary:
Bit 20 in sve2_int_arith_pred TableGen class was overlapping. The
encodings are not affected as bit 20 is defined by the opc bits
and this was overwriting the earlier error of setting bit 20 to 0.

5 years ago[DSE] Bugfix to avoid PartialStoreMerging involving non byte-sized stores

[DSE] Bugfix to avoid PartialStoreMerging involving non byte-sized stores

Summary:
The DeadStoreElimination pass now skips doing
PartialStoreMerging when stores overlap according to
OW_PartialEarlierWithFullLater and at least one of
the stores is having a store size that is different
from the size of the type being stored.

This solves problems seen in
  https://bugs.llvm.org/show_bug.cgi?id=41949
for which we in the past could end up with
mis-compiles or assertions.

The content and location of the padding bits is not
formally described (or undefined) in the LangRef
at the moment. So the solution is chosen based on
that we cannot assume anything about the padding bits
when having a store that clobbers more memory than
indicated by the type of the value that is stored
(such as storing an i6 using an 8-bit store instruction).

DWARF: Implement DW_AT_signature lookup for type unit support

Summary:
This patch implements the main feature of type units. When completing a
type, if we encounter a DW_AT_signature attribute, we use it's value to
lookup the complete definition of the type in the relevant type unit.

To enable this lookup, we build up a map of all type units in a symbol
file when parsing the units. Then we consult this map when resolving the
DW_AT_signature attribute.

I include add a couple of tests which exercise the type lookup feature,
including one that ensure we do something reasonable in case we fail to
lookup the type.

A lot of the ideas in this patch have been taken from D32167 and D61505.

Pavel Labath [Fri, 24 May 2019 08:04:03 +0000 (08:04 +0000)]
DWARFContext: Make loading of sections thread-safe

Summary:
SymbolFileDWARF used to load debug sections in a thread-safe manner.
When we moved to DWARFContext, we dropped the thread-safe part, because
we thought it was not necessary.

It turns out this was only mostly correct.

The "mostly" part is there because this is a problem only if we use the
manual index, as that is the only source of intra-module paralelism.
Also, this only seems to occur for extremely simple files (like the ones
I've been creating for tests lately), where we've managed to start
indexing before loading the debug_str section. Then, two threads start
to load the section simultaneously and produce wrong results.

On more complex files, something seems to be loading the debug_str section
before we start indexing, as I haven't been able to reproduce this
there, but I have not investigated what it is.

I've tried to come up with a test for this, but I haven't been able to
reproduce the problem reliably. Still, while doing so, I created a way
to generate many compile units on demand. Given that most of our tests
work with only one or two compile units, it seems like this could be
useful anyway.
