Hector Diaz 4ec6ebabfc [lldb-vscode] Add inheritEnvironment option
Summary:
If no custom launching is used, lldb-vscode launches a program with an empty environment by default. In some scenarios, the user might want to simply use the same environment as the IDE to have a set of working environment variables (e.g. PATH wouldn't be empty). In fact, most DAPs in VSCode have this behavior by default. In other cases the user definitely needs to set their custom environment, which is already supported. To make the first case easier for the user (e.g. not having to copy the PATH to the launch.json every time they want to debug simple programs that rely on PATH), a new option is now offered. inheritEnvironment will launch the program copying its own environment, and it's just a boolean flag.

Jonas Devlieghere 09c8845adf [lldb]/Tablegen] Use ElementType instead of DefaultValueUnsinged
The fourth field in the property struct is the default unsigned or enum
value for all types, except for Array and Dictionary types. For those,
it is the element type. During the tablegen conversion, this was
incorrectly translated to DefaultValueUnsigned with a value
corresponding to the OptionValue: enum type. So for
OptionValue::eTypeString this became DefaultUnsignedValue<16>. This
patch extends the tablegen backend to understand ElementType to express
this as ElementType<"String">.

Richard Smith dc4259d5a3 [c++20] Further extend the set of comparisons broken by C++20 that we

This attempts to accept the same cases a GCC, plus cases where a
comparison is rewritten to an operator== with an integral but non-bool
return type; this is sufficient to avoid most problems with various
major open-source projects (such as ICU) and appears to fix all but one
of the comparison-related C++20 build breaks in LLVM.

This approach is being pursued for standardization.

Nikita Popov 2b52e4e629 [InstCombine] Remove known bits constant folding
If ExpensiveCombines is enabled (which is the case with -O3 on the
legacy PM and always on the new PM), InstCombine tries to compute
the known bits of all instructions in the hope that all bits end up
being known, which is fairly expensive.

How effective is it? If we add some statistics on how often the
constant folding succeeds and how many KnownBits calculations are
performed and run test-suite we get:

    "instcombine.NumConstPropKnownBits": 642,
    "instcombine.NumConstPropKnownBitsComputed": 18744965,

In other words, we get one fold for every 30000 KnownBits calculations.
However, the truth is actually much worse: Currently, known bits are
computed before performing other folds, so there is a high chance
that cases that get folded by known bits would also have been
handled by other folds.

What happens if we compute known bits after all other folds
(hacky implementation: https://gist.github.com/nikic/751f25b3b9d9e0860db5dde934f70f46)?

    "instcombine.NumConstPropKnownBits": 0,
    "instcombine.NumConstPropKnownBitsComputed": 18105547,

So it turns out despite doing 18 million known bits calculations,
the known bits fold does not do anything useful on test-suite.
I was originally planning to move this into AggressiveInstCombine
so it only runs once in the pipeline, but seeing this, I think
we're better off removing it entirely.

As this is the only use of the "expensive combines" mechanism,
it may be removed afterwards, but I'll leave that to a separate patch.

Use the advanceToLowerBound operation available on CoalescingBitVector
iterators to speed up collection of variables which reside within some

The speedup comes from avoiding repeated top-down traversals in
IntervalMap::find. The linear scan forward from one register interval to
the next is unlikely to be as expensive as a full IntervalMap search
starting from the root.

This reduces time spent in LiveDebugValues when compiling sqlite3 by
200ms (about 0.1% - 0.2% of the total User Time).
