The newline-eof fix was rendered as "insert '...'", this patch
special-case it.

canSkipDef() currently skips inaccessiblememonly calls, but not
if they are allocation functions. This check was added in D103009,
but actually seems to be a leftover from a previous implementation
in D101440. canSkipDef() is not used on the storeIsNoop() path,
where the relevant transform ended up being implemented.

This style is similar to AlwaysBreak, but places closing brackets on new lines.
For example, if you have a multiline parameter list, clang-format currently only supports breaking per-parameter, but places the closing bracket on the line of the last parameter.
Function(
param1,
param2,
param3);
A style supported by other code styling tools (e.g. rustfmt) is to allow the closing brackets to be placed on their own line, aiding the user in being able to quickly infer the bounds of the block of code.
Function(
param1,
param2,
param3
);
For prior work on a similar feature, see: https://reviews.llvm.org/D33029.
Note: This currently only supports block indentation for closing parentheses.

Those two TTI hooks are used during vectorization for calculating
register pressure, the default implementation isn't consider for LMUL,
and that's also definitly wrong value for register number (all register class
are 8 registers).
So in this patch we tried to:
1. Calculate right register usage for vector type and scalar type.
2. Return right number of register for general purpose register and
vector register.

Targets with VSX feature but without native float128 instructions can
also use that type with supplementary libcalls. We don't enable it by
default now because Glibc assumes long double and float128 can be
implicitly converted in between, which is not available under default
'ibmlongdouble' semantics in clang.
This commit partly relands cbd93ce.
After the D33630 fallout was properly fixed by a4c5db30be4e216834b44e31b47304ea1b92635f.
Tested by D37462/D44986 tests, the new --no-rosegment test in build-id.s, and a few --rosegment/--no-rosegment programs.
This is unused, and doesn't make a lot of sense as an API. The
usual pattern would be to combine the AttrBuilder(AttributeSet)
constructor with the overlaps() method.
Update code comments in DAGCombiner::ReduceLoadWidth and refactor
the handling of SRL a bit. The refactoring is done with the intent
of adding support for folding away SRA by using SEXTLOAD in a
follow-up patch.
The function is also renamed as DAGCombiner::reduceLoadWidth.

Move all variables at file-scope or function-static-scope into a hosting structure (lld::CommonLinkerContext) that lives at lldMain()-scope. Drivers will inherit from this structure and add their own global state, in the same way as for the existing COFFLinkerContext.

After d4a8fc3a87a1 LV stopped adding metadata to disable runtime
unrolling to the vectorized epilogue loop. This was missed because
278aa65cc495 removed the relevant test coverage.
This patch fixes that by adding the relevant metadata after
vector loop generation.
1b1c8d changed `enable-noundef-analysis` flag to
`disable-noundef-analysis`. noundef_analysis.cpp was using old
`enable-noundef-analysis` flag and this patch fixes it.
Turning on `enable_noundef_analysis` flag allows better codegen by removing freeze instructions.
I modified clang by renaming `enable_noundef_analysis` flag to `disable-noundef-analysis` and turning it off by default.
Test updates are made as a separate patch: D108453

Sorting dynamic relocations is a bottleneck. Simplifying the comparator improves
performance. Linking clang is 4~5% faster with --threads=8.
This change may shuffle R_MIPS_REL32 for Mips and is a NFC for non-Mips.
This is the original patch in my GNUInstallDirs series, now last to merge as the final piece!
It arose as a new draft of D28234. I initially did the unorthodox thing of pushing to that when I wasn't the original author, but since I ended up
- Using `GNUInstallDirs`, rather than mimicking it, as the original author was hesitant to do but others requested.
- Converting all the packages, not just LLVM, effecting many more projects than LLVM itself.
I figured it was time to make a new revision.
I have used this patch series (and many back-ports) as the basis of https://github.com/NixOS/nixpkgs/pull/111487 for my distro (NixOS), which was merged last spring (2021). It looked like people were generally on board in D28234, but I make note of this here in case extra motivation is useful.
---
As pointed out in the original issue, a central tension is that LLVM already has some partial support for these sorts of things. Variables like `COMPILER_RT_INSTALL_PATH` have already been dealt with. Variables like `LLVM_LIBDIR_SUFFIX` however, will require further work, so that we may use `CMAKE_INSTALL_LIBDIR`.
These remaining items will be addressed in further patches. What is here is now rote and so we should get it out of the way before dealing more intricately with the remainder.
