[NFC][Clang][RISCV] Reduce boilerplate when determining prototype for segment loads

No functionality change of the RVV builtin and compiler intrinsics is intended

This patch gathers scattered comments for the segment load builtin/intrinsics
and its variants (e.g. segment unit-stride load, segment strided load) into a
single paragraph under riscv_vector.td.

are essentially the same actions but differs in index based on the the value
of the policy attributes and whether the intrinsic is masked.

with gpu.known_{block,grid}_size, use that size to set a "range"
attribute on the corresponding rocdl intrinsic so that the LLVM
frontend can optimize based on that range information.

function call.
2. Deprecate the old rocdl.max_flat_work_group_size attribute, which
was used in a tensorflow backend. Instead, use
rocdl.flat_work_group_size going forward to allow kernel generators to
specify the minimum and maximum work group sizes a kernel may be
launched with in one attribute, thus more closely matching the backend.
3. When translating from gpu.func to llvm.func within gpu-to-rocdl,
copy the known_block_size attribute as rocdl.reqd_work_group_size to
enable further translations to set the corresponding metadata on the
LLVM IR function. Also, set the rocdl.flat_work_group_size attribute
to ensure that the reqd_work_group_size metadata and the
amdgpu-flat-work-group-size metadata are consistent.
3b. Extend the ROCDL to LLVM IR translation to set the
!reqd_work_group_size metadata on LLVM functions

Also update tests and add functions to the ROCDL dialect to ensure

[mlir][llvm] Make the import of LLVM IR intrinsics extensible.

The revision introduces the LLVMImportDialectInterface to make the
import of LLVM IR intrinsics extensible. It uses a dialect interface
that enables external projects to provide their own conversion functions
for custom intrinsics. These conversion functions can rely on the
ModuleImport class to perform support tasks such as mapping LLVM
values to MLIR values or for converting types between the two worlds.

The implementation largely mirrors the export implementation. One major
difference is the dispatch to the appropriate dialect interface, since
LLVM IR intrinsics have no direct association to an MLIR dialect. The
dialect interfaces thus have to publish the supported intrinsics to
ensure incoming conversion calls are dispatched to the right dialect
interface.

Teresa Johnson [Thu, 29 Dec 2022 20:11:38 +0000 (12:11 -0800)]
[MemProf] Fix inline propagation of memprof metadata

It isn't correct to always remove memprof metadata MIBs from the
original allocation call after inlining.

Let's say we have the following partial call graph:

C     D
 \   /
  v v
   B   E
   |  /
   v v
    A

where A contains an allocation call. If both contexts including B have
the same allocation behavior, the context in the memprof metadata on the
allocation will be pruned, and we will have 2 MIBs with contexts:
A,B and A,E.

Previously, if we inlined A into B we propagate the matching MIBs onto
the inlined allocation call in B' (A,B in this case), and remove it from
the original out of line allocation in A. This is correct if we have a
single round of bottom up inlining.

However, in the compiler we can have multiple invocations of the inliner
pass (e.g. LTO). We may also inline non-bottom up with an alternative
inliner such as the ModuleInliner. In that case, we could end up first
inlining B into C, without having inlined A into B. The call graph then
looks like:

    D
    |
    v
C'  B   E
 \  |  /
  v v v
    A

If we subsequently (perhaps on a later invocation of bottom up inlining)
inline A into B, the previous handling would propagate the memprof MIB
context A,B up into the inlined allocation in B', and remove it from the
original allocation in A. The propagation into B' is fine, however, by
removing it from A's allocation, we no longer reflect the context coming
from C'.

To fix this, simply prevent the removal of MIB from the original
allocation callsites.

Note that the memprof_inline.ll test has some changes to existing
checking to replace "noncold" with "notcold" in the metadata. The
corresponding CHECK was accidentally commented out in the old version
and thus this mistake was not previously detected.
