4 years ago[ARM,MVE] Fix vreinterpretq in big-endian mode.
Simon Tatham [Mon, 3 Feb 2020 09:35:36 +0000 (09:35 +0000)]
[ARM,MVE] Fix vreinterpretq in big-endian mode.

Summary:
In big-endian MVE, the simple vector load/store instructions (i.e.
both contiguous and non-widening) don't all store the bytes of a
register to memory in the same order: it matters whether you did a
VSTRB.8, VSTRH.16 or VSTRW.32. Put another way, the in-register
formats of different vector types relate to each other in a different
way from the in-memory formats.

So, if you want to 'bitcast' or 'reinterpret' one vector type as
another, you have to carefully specify which you mean: did you want to
reinterpret the //register// format of one type as that of the other,
or the //memory// format?

The ACLE `vreinterpretq` intrinsics are specified to reinterpret the
register format. But I had implemented them as LLVM IR bitcast, which
is specified for all types as a reinterpretation of the memory format.
So a `vreinterpretq` intrinsic, applied to values already in registers,
would code-generate incorrectly if compiled big-endian: instead of
emitting no code, it would emit a `vrev`.

To fix this, I've introduced a new IR intrinsic to perform a
register-format reinterpretation: `@llvm.arm.mve.vreinterpretq`. It's
implemented by a trivial isel pattern that expects the input in an
MQPR register, and just returns it unchanged.

In the clang codegen, I only emit this new intrinsic where it's
actually needed: I prefer a bitcast wherever it will have the right
effect, because LLVM understands bitcasts better. So we still generate
bitcasts in little-endian mode, and even in big-endian when you're
casting between two vector types with the same lane size.

For testing, I've moved all the codegen tests of vreinterpretq out
into their own file, so that they can have a different set of RUN
lines to check both big- and little-endian.

4 years ago[ARM,MVE] Add intrinsics for v[id]dupq and v[id]wdupq.

[ARM,MVE] Add intrinsics for v[id]dupq and v[id]wdupq.

Summary:
These instructions generate a vector of consecutive elements starting
from a given base value and incrementing by 1, 2, 4 or 8. The `wdup`
versions also wrap the values back to zero when they reach a given
limit value. The instruction updates the scalar base register so that
another use of the same instruction will continue the sequence from
where the previous one left off.

At the IR level, I've represented these instructions as a family of
target-specific intrinsics with two return values (the constructed
vector and the updated base). The user-facing ACLE API provides a set
of intrinsics that throw away the written-back base and another set
that receive it as a pointer so they can update it, plus the usual
predicated versions.

Because the intrinsics return two values (as do the underlying
instructions), the isel has to be done in C++.

This is the first family of MVE intrinsics that use the `imm_1248`
immediate type in the clang Tablegen framework, so naturally, I found
I'd given it the wrong C integer type. Also added some tests of the
check that the immediate has a legal value, because this is the first
time those particular checks have been exercised.

Finally, I also had to fix a bug in MveEmitter which failed an
assertion when I nested two `seq` nodes (the inner one used to extract
the two values from the pair returned by the IR intrinsic, and the
outer one put on by the predication multiclass).

between the same vector splat and the `inactive` input parameter, and
added new Tablegen isel rules to match that pattern into a predicated

[lldb] Increase the rate at which ConstString's memory allocator scales the memory chunks it allocates

Summary:
We currently do far more malloc calls than necessary in the ConstString BumpPtrAllocator. This is due to the 256 BumpPtrAllocators
our ConstString implementation uses internally which end up all just receiving a small share of the total allocated memory
and therefore keep allocating memory in small chunks for far too long. This patch fixes this by increasing the rate at which we increase the
memory chunk size so that our collection of BumpPtrAllocators behaves in total similar to a single BumpPtrAllocator.

[llvm] Add a way to speed up the speed in which BumpPtrAllocator increases slab sizes

Summary:
In D68549 we noticed that our BumpPtrAllocator we use for LLDB's ConstString implementation is growing its slabs at
a rate that is too slow for our use case. It causes that we spend a lot of time calling `malloc` for all the tiny slabs that our
ConstString BumpPtrAllocators create. We also can't just increase the slab size in the ConstString implementation
(which is what D68549 originally did) as this really increased the amount of (mostly unused) allocated memory
in any process using ConstString.

This patch adds a template argument for the BumpPtrAllocatorImpl that allows specifying a faster rate at which the
BumpPtrAllocator increases the slab size. This allows LLDB to specify a faster rate at which the slabs grow which
should keep both memory consumption and time spent calling malloc low.

TraitSelector, and TraitProperty as well as conversion and helper
