[MirNamer][Canonicalizer]: Perform instruction semantic based renaming
https://reviews.llvm.org/D70210
Previously:
Due to sensitivity of the algorithm with gaps, and extra instructions,
when diffing, often we see naming being off by a few. Makes the diff
unreadable even for tests with 7 and 8 instructions respectively.
Naming can change depending on candidates (and order of picking
candidates). Suddenly if there's one extra instruction somewhere, the
entire subtree would be named completely differently.
No consistent naming of similar instructions which occur in different
functions. If we try to do something like count the frequency
distribution of various differences across suite, then the above
sensitivity issues are going to result in poor results.
Instead:
Name instruction based on semantics of the instruction (hash of the
opcode and operands). Essentially for a given instruction that occurs in
any module/function it'll be named similarly (ie semantic). This has
some nice properties
Can easily look at many instructions and just check the hash and if
they're named similarly, then it's the same instruction. Makes it very
easy to spot the same instruction both multiple times, as well as across
many functions (useful for frequency distribution).
Independent of traversal/candidates/depth of graph. No need to keep
track of last index/gaps/skip count etc.
No off by few issues with diffs. I've tried the old vs new
implementation in files ranging from 30 to 700 instructions. In both
cases with the old algorithm, diffs are a sea of red, where as for the
semantic version, in both cases, the diffs line up beautifully.
Simplified implementation of the main loop (simple iteration) , no keep
track of what's visited and not.
Handle collision just by incrementing a counter. Roughly
bb[N]_hash_[CollisionCount].
Additionally with the new implementation, we can probably avoid doing
the hoisting of instructions to various places, as they'll likely be
named the same resulting in differences only based on collision (ie
regardless of whether the instruction is hoisted or not/close to use or
not, it'll be named the same hash which should result in use of the
instruction be identical with the only change being the collision count)
which is very easy to spot visually.

[RISCV] Match GCC `-march`/`-mabi` driver defaults
Summary:
Clang/LLVM is a cross-compiler, and so we don't have to make a choice
about `-march`/`-mabi` at build-time, but we may have to compute a
default `-march`/`-mabi` when compiling a program. Until now, each
place that has needed a default `-march` has calculated one itself.
This patch adds a single place where a default `-march` is calculated,
in order to avoid calculating different defaults in different places.
This patch adds a new function `riscv::getRISCVArch` which encapsulates
this logic based on GCC's for computing a default `-march` value
when none is provided. This patch also updates the logic in
`riscv::getRISCVABI` to match the logic in GCC's build system for
computing a default `-mabi`.
This patch also updates anywhere that `-march` is used to now use the
new function which can compute a default. In particular, we now
explicitly pass a `-march` value down to the gnu assembler.
GCC has convoluted logic in its build system to choose a default
`-march`/`-mabi` based on build options, which would be good to match.
This patch is based on the logic in GCC 9.2.0. This commit's logic is
different to GCC's only for baremetal targets, where we default
to rv32imac/ilp32 or rv64imac/lp64 depending on the target triple.
Tests have been updated to match the new logic.

[ARM,MVE] Add reversed isel patterns for MVE `vcmp qN,rN`
Summary:
As well as vector/vector compare instructions, MVE also has a family
of comparisons taking a vector and a scalar, which compare every lane
of the vector against the same value. We generate those at isel time
using isel patterns that match `(ARMvcmp vector, (ARMvdup scalar))`.
This commit adds corresponding patterns for the operand-reversed form
`(ARMvcmp (ARMvdup scalar), vector)`, with condition codes swapped as
necessary. That way, we can still generate the vector/scalar compare
instruction if the IR happens to have been rearranged to put the
operands the other way round, which can happen in some optimization
phases. Previously, a vcmp the other way round was handled by emitting
a `vdup` instruction to //explicitly// replicate the scalar input into
a vector, and then doing a vector/vector comparison.
I haven't added a new test, because it turned out that several
existing tests were already exhibiting that failure mode. So just
updating the expected output in the existing MVE codegen tests
demonstrates what's been improved.

DWARFDebugLoc(v4): Add an incremental parsing function
Summary:
This adds a visitLocationList function to the DWARF v4 location lists,
similar to what already exists for DWARF v5. It follows the approach
outlined in previous patches (D69672), where the parsed form is always
stored in the DWARF v5 format, which makes it easier for generic code to
be built on top of that. v4 location lists are "upgraded" during
parsing, and then this upgrade is undone while dumping.
Both "inline" and section-based dumping is rewritten to reuse the
existing "generic" location list dumper. This means that the output
format is consistent for all location lists (the only thing one needs to
implement is the function which prints the "raw" form of a location
list), and that debug_loc dumping correctly processes base address
selection entries, etc.
The previous existing debug_loc functionality (e.g.,
parseOneLocationList) is rewritten on top of the new API, but it is not
removed as there is still code which uses them. This will be done in
follow-up patches, after I build the API to access the "interpreted"
location lists in a generic way (as that is what those users really
want).

[ARM,MVE] Add intrinsics for vector get/set lane.
This adds the `vgetq_lane` and `vsetq_lane` families, to copy between
a scalar and a specified lane of a vector.
One of the new `vgetq_lane` intrinsics returns a `float16_t`, which
causes a compile error if `%clang_cc1` doesn't get the option
`-fallow-half-arguments-and-returns`. The driver passes that option to
cc1 already, but I've had to edit all the explicit cc1 command lines
in the existing MVE intrinsics tests.
A couple of fixes are included for the code I wrote up front in
MveEmitter to support lane-index immediates (and which nothing has
tested until now): the type was wrong (`uint32_t` instead of `int`)
and the range was off by one.
I've also added a method of bypassing the default promotion to `i32`
that is done by the MveEmitter code generation: it's sensible to
promote short scalars like `i16` to `i32` if they're going to be
passed to custom IR intrinsics representing a machine instruction
operating on GPRs, but not if they're going to be passed to standard
IR operations like `insertelement` which expect the exact type.

don't-care contents); and `vcreateq` (make a 128-bit vector out of two
`uint64_t` halves).
These are all implemented using completely standard IR that's already
tested in existing LLVM unit tests, so I've just written a clang test
to check the IR is correct, and left it at that.
I've also added some richer infrastructure to the MveEmitter Tablegen
backend, to make it specify the exact integer type of integer
arguments passed to IR construction functions, and wrap those
arguments in a `static_cast` in the autogenerated C++. That was
necessary to prevent an overloading ambiguity when passing the integer

[SanitizerCommon] Print the current value of options when printing out help.
Summary:
Previously it wasn't obvious what the default value of various sanitizer
options were. A very close approximation of the "default values" for the
options are the current value of the options at the time of printing the
help output.
In the case that no other options are provided then the current values
are the default values (apart from `help`).
```
ASAN_OPTIONS=help=1 ./program
```
This patch causes the current option values to be printed when the
`help` output is enabled. The original intention for this patch was to append
`(Default: <value>)` to an option's help text. However because this
is technically wrong (and misleading) I've opted to append
`(Current Value: <value>)` instead.
When trying to implement a way of displaying the default value of the
options I tried another solution where the default value used in `*.inc` files
were used to create compile time strings that where used when printing
the help output. This solution was not satisfactory for several reasons:
* Stringifying the default values with the preprocessor did not work very
well in several cases. Some options contain boolean operators which no
amount of macro expansion can get rid of.
* It was much more invasive than this patch. Every sanitizer had to be changed.
* The settings of `__<sanitizer>_default_options()` are ignored.
For those reasons I opted for the solution in this patch.

[Hexagon] Fix clang driver to parse -mcpu/-mvXX and -march properly.

the driver fails to figure out the correct cpu version. This patch fixed this
issue.
