Move from llvm::makeArrayRef to ArrayRef deduction guides - llvm/ part

2023-01-05T13:11:08+00:00

Use deduction guides instead of helper functions.

The only non-automatic changes have been:

1. ArrayRef(some_uint8_pointer, 0) needs to be changed into ArrayRef(some_uint8_pointer, (size_t)0) to avoid an ambiguous call with ArrayRef((uint8_t*), (uint8_t*))
2. CVSymbol sym(makeArrayRef(symStorage)); needed to be rewritten as CVSymbol sym{ArrayRef(symStorage)}; otherwise the compiler is confused and thinks we have a (bad) function prototype. There was a few similar situation across the codebase.
3. ADL doesn't seem to work the same for deduction-guides and functions, so at some point the llvm namespace must be explicitly stated.
4. The "reference mode" of makeArrayRef(ArrayRef &) that acts as no-op is not supported (a constructor cannot achieve that).

Per reviewers' comment, some useless makeArrayRef have been removed in the process.

This is a follow-up to https://reviews.llvm.org/D140896 that introduced
the deduction guides.

[CodeGen] llvm::Optional => std::optional

2022-12-13T09:06:36+00:00

[CodeGen] Use std::nullopt instead of None (NFC)

2022-12-03T04:36:08+00:00

This patch mechanically replaces None with std::nullopt where the
compiler would warn if None were deprecated.  The intent is to reduce
the amount of manual work required in migrating from Optional to
std::optional.

This is part of an effort to migrate from llvm::Optional to
std::optional:

DebugInfo: Move loclist base address from DwarfFile to DebugLocStream

2019-10-17T23:02:19+00:00

There's no need to have more than one of these (there can be two
DwarfFiles - one for the .o, one for the .dwo - but only one loc/loclist
section (either in the .o or the .dwo) & certainly one per
DebugLocStream, which is currently singular in DwarfDebug)

Change Comments SmallVector to std::vector in DebugLocStream [NFC]

2019-10-15T09:21:09+00:00

This changes the 32-element SmallVector to a std::vector. When building
a RelWithDebInfo clang-8 binary, the average size of the vector was
~10000, so it does not seem very beneficial or practical to use a small
vector for that.

The DWARFBytes SmallVector grows in the same way as Comments, so perhaps
that also should be changed to a purely dynamically allocated structure,
but that requires some more code changes, so I let that remain as a
SmallVector for now.

DebugInfo: Rename DebugLocStream::Entry::Begin/EndSym to just Begin/End

2019-10-02T22:58:02+00:00

Brings this struct in line with the RangeSpan class so they might
eventually be used by common template code for generating range/loc
lists with less duplicate code.
