Guillaume Chatelet [Wed, 19 Apr 2023 14:57:14 +0000 (14:57 +0000)]
[libc] Improve memcmp latency and codegen

This is based on ideas from @nafi to:
 - use a branchless version of 'cmp' for 'uint32_t',
 - completely resolve the lexicographic comparison through vector
   operations when wide types are available. We also get rid of byte
   reloads and serializing '__builtin_ctzll'.

I did not include the suggestion to replace comparisons of 'uint16_t'
with two 'uint8_t' as it did not seem to help the codegen. This can
be revisited in sub-sequent patches.

The code been rewritten to reduce nested function calls, making the
job of the inliner easier and preventing harmful code duplication.

[NFC][RFC][TableGen] Split GlobalISelEmitter.cpp

This patch splits the GlobalISelEmitter.cpp file, which imports DAG ISel patterns for GISel, into separate "GISelMatchTable.h/cpp" files.

The main motive is readability & maintainability. GlobalISelEmitter.cpp was about 6400 lines of mixed code, some bits implementing the match table codegen, some others dedicated to importing DAG patterns.

Now it's down to  2700 + a 2150 header + 2000 impl.
It's a tiny bit more lines overall but that's to be expected - moving
inline definitions to out-of-line, adding comments in the .cpp, etc. all of that takes additional space, but I think the tradeoff is worth it.

I did as little unrelated code changes as possible, I would say the biggest change is the introduction of the `gi` namespace used to prevent name conflicts/ODR violations with type common names such as `Matcher`.
It was previously not an issue because all of the code was in an anonymous namespace.

This moves all of the "match table" code out of the file, so predicates,
rules, and actions are all separated now. I believe this helps separating concerns, now `GlobalISelEmitter.cpp` is more focused on importing DAG patterns into GI, instead of also containing the whole match table internals as well.

Note: the new files have a "GISel" prefix to make them distinct from the other "GI" files in the same folder, which are for the combiner.

[FPEnv] Intrinsics for access to FP environment

The change implements intrinsics 'get_fpenv', 'set_fpenv' and 'reset_fpenv'.
They are used to read floating-point environment, set it or reset to
some default state. They do the same actions as C library functions
'fegetenv' and 'fesetenv'. By default these intrinsics are lowered to calls
to these functions.

The new intrinsics specify FP environment as a value of integer type, it
is convenient of most targets where the FP state is a content of some
register. Some targets however use long representations. On X86 the size
of FP environment is 256 bits, and even half of this size is not a legal
ibteger type. To facilitate legalization in such cases, two sets of DAG
nodes is used. Nodes GET_FPENV and SET_FPENV are used when FP
environment may be represented by a legal integer type. Nodes
GET_FPENV_MEM and SET_FPENV_MEM consider FP environment as a region in
memory, much like `fesetenv` and `fegetenv` do. They are used when
target has long representation for floationg-point state.

Sergei Barannikov [Sat, 20 May 2023 18:30:02 +0000 (21:30 +0300)]
[CodeGen] Fix incorrect usage of MCPhysReg for diff list elements

The lists contain differences between register numbers, not the register
numbers themselves. Since a difference can also be negative, this also
changes its type to signed.

Changing the type to signed exposed a "bug". For AMDGPU, which has many
registers, the first element of a sequence could be as big as ~45k.
The value does not fit into int16_t, but fits into uint16_t. The bug
didn't show up because of unsigned wrapping and truncation of the Val
field in the advance() method.

To fix the issue, I changed the way regunit difflists are encoded. The
4-bit 'scale' field of MCRegisterDesc::RegUnit was replaced by 12-bit
number of the first regunit, and the first element of each of the lists
was removed. The higher 20 bits of RegUnit field contain the initial
offset into DiffLists array.
AMDGPU has 1'409 regunits (2^12 = 4'096), and the biggest offset is
80'041 (2^20 = 1'048'576). That is, there is enough room.

Changing the encoding method also resulted in a smaller array size, the
numbers are below (I omitted targets with less than 100 elements).

```
AMDGPU   | 80052 | 78741 |  -1,6%

[libcxx] Fix using std::wcout/wcin on Windows with streams configured in wide mode

On Windows, the underlying file descriptors for stdout/stdin/stderr
can be reconfigured to wide mode. In the default (narrow) mode, the
charset usually isn't utf8 (as libcxx assumes), but normally a locale
specific codepage (where each codepage only can represent a small
subset of unicode characters).

By configuring the stdout file descriptor to wide mode, the user can
output wchar_t based strings without convesion to the narrow charset.
Within libcxx, don't try to use codecvt to convert this to a narrow
character encoding, but output these strings as such with fputwc.

In wide mode, such strings could be output directly with fwrite too,
but if the file descriptor hasn't been configured in wide mode, that
breaks the output (which currently works reasonably). By always
outputting one character at a time with fputwc, it works regardless
of mode of the stdout file descriptor.

For the narrow output stream, std::cout, outputting (via fwrite)
does fail when the file descriptor is set to wide mode. This matches
how it behaves with both MS STL and GNU libstdc++ too, so this is
probably acceptable.

This fixes https://github.com/llvm/llvm-project/issues/46646, and

This is missing the new GetClangResourceDir.cmake that is being included,

[TableGen][GlobalISel] Account for HwMode in RegisterBank register sizes

This patch adds logic for determining RegisterBank size to RegisterBankInfo, which allows accounting for the HwMode of the target. Individual RegisterBanks cannot be constructed with HwMode information as construction is generated by TableGen, but a RegisterBankInfo subclass can provide the HwMode as a constructor argument. The HwMode is used to select the appropriate RegisterBank size from an array relating sizes to RegisterBanks.

Targets simply need to provide the HwMode argument to the <target>GenRegisterBankInfo constructor. The RISC-V RegisterBankInfo constructor has been updated accordingly (plus an unused argument removed).

[AMDGPU] Don't flush vmcnt for loops with use/def pairs

Conditions for hoisting vmcnt with flat instructions should be similar to VMEM.
If there are use/def pairs in a loop body we cannot guarantee that hosting the
waitcnt will be profitable. Better heuristics are needed to analyse whether
gains from avoiding waitcnt in loop bodys outweighs waiting for loads in the
