Aaron Ballman [Mon, 14 Mar 2022 13:22:37 +0000 (09:22 -0400)]
Implement literal suffixes for _BitInt

WG14 adopted N2775 (http://www.open-std.org/jtc1/sc22/wg14/www/docs/n2775.pdf)
at our Feb 2022 meeting. This paper adds a literal suffix for
bit-precise types that automatically sizes the bit-precise type to be
the smallest possible legal _BitInt type that can represent the literal
value. The suffix chosen is wb (for a signed bit-precise type) which
can be combined with the u suffix (for an unsigned bit-precise type).

The preprocessor continues to operate as-if all integer types were
intmax_t/uintmax_t, including bit-precise integer types. It is a
constraint violation if the bit-precise literal is too large to fit
within that type in the context of the preprocessor (when still using
a pp-number preprocessing token), but it is not a constraint violation
in other circumstances. This allows you to make bit-precise integer
literals that are wider than what the preprocessor currently supports
in order to initialize variables, etc.

2 years agoHave cpu-specific variants set 'tune-cpu' as an optimization hint
Erich Keane [Thu, 10 Mar 2022 21:31:52 +0000 (13:31 -0800)]
Have cpu-specific variants set 'tune-cpu' as an optimization hint

Due to various implementation constraints, despite the programmer
choosing a 'processor' cpu_dispatch/cpu_specific needs to use the
'feature' list of a processor to identify it. This results in the
identified processor in source-code not being propogated to the
optimizer, and thus, not able to be tuned for.

This patch changes to use the actual cpu as written for tune-cpu so that
opt can make decisions based on the cpu-as-spelled, which should better
match the behavior expected by the programmer.

Note that the 'valid' list of processors for x86 is in
llvm/include/llvm/Support/X86TargetParser.def. At the moment, this list
contains only Intel processors, but other vendors may wish to add their
own entries as 'alias'es (or with different feature lists!).

If this is not done, there is two potential performance issues with the
patch, but I believe them to be worth it in light of the improvements to
behavior and performance.

1- In the event that the user spelled "ProcessorB", but we only have the
features available to test for "ProcessorA" (where A is B minus
features),
AND there is an optimization opportunity for "B" that negatively affects
"A", the optimizer will likely choose to do so.

2- In the event that the user spelled VendorI's processor, and the
feature
list allows it to run on VendorA's processor of similar features, AND
there
is an optimization opportunity for VendorIs that negatively affects
"A"s,
the optimizer will likely choose to do so. This can be fixed by adding
an
alias to X86TargetParser.def.

[RISCV] Add DAGCombine to fold (bitreverse (bswap X)) to brev8 with Zbkb.

If the type is less than XLenVT, type legalization will turn this
into (srl (bitreverse (bswap (srl (bswap X), C))), C). We can't
completely recover from these shifts. They introduce zeros into
the upper bits of the result and we can't easily tell if they are
needed. By doing a DAG combine early, we avoid introducing these
shifts.

Where possible, I added additional information to the messages to help
programmers figure out what went wrong.  I also removed all uses of the word
"bad" from the messages since (to me) that implies a moral judgement rather
than a programming error.  I replaced it with either "invalid" or "unsupported"
where appropriate.

[DebugInfo] Include DW_TAG_skeleton_unit when looking for parent UnitDie

`DIE::getUnitDie` looks up parent DIE until compile unit or type unit is found. However for skeleton CU with debug fission, we would have DW_TAG_skeleton_unit instead of DW_TAG_compile_unit as top level DIE.

This change fixes the look up so we can get DW_TAG_skeleton_unit as UnitDie for skeleton CU.
