This should be a trivial change, and I've started using it for generating all
tests at https://github.com/lowrisc/riscv-llvm (i.e. it's been tested in
action quite a lot). Note that the regex does not attempt to match
.cfi_startproc, as I want to ensure compatibility with functions that have the
nounwind attribute.

Ideally, we should compare 32- and 64-bit versions to see if the
ret line is the only difference and then insert the regex only
in that case. But this is a quick hack to avoid a bunch of noise
as existing tests are updated.

Summary:
In D37523 Sanjay pointed out that the tool does not scrub macosx-style 'End of Function' annotations,
where the comments begin with a double-#.
I tested this patch by verifying all existing occurences of 'End function' are scrubbed:
find ./test/CodeGen/X86 -name '*.ll' | xargs grep -l "End function" | xargs utils/update_llc_test_checks.py --llc-binary build/bin/llc

When I tried running the script, the ARM regex parser could not parse
my code. It failed because the .Lfunc_end line has a comment at the
end of it, so this commit removes the newline at the end of the regex.

If there's some reason not to do this, feel free to revert and/or fix, but
for the cases I'm looking at, the script appears to do fine for these targets.

This patch adds support for including the avx512 mask register information in the mask/maskz versions of shuffle instruction comments.
This initial version just adds support for MOVDDUP/MOVSHDUP/MOVSLDUP to reduce the mass of test regenerations, other shuffle instructions can be added in due course.

We lose the 'utils' directory name in our advertising line with
this change. We could retain that, but I don't see the point.
This removes a dependency for making the script apply to more than
'llc'. Ie, we'll want to change the script name if it works with
opt/clang too.

The goal is to enhance this script to be used with opt and clang:
Break 'main' into functions and change variable names to be more
generic because we want to handle more than x86 asm output.

The goal is to enhance this script to be used with opt and clang:
Group all of the regexes together, so it's easier to see what's going on.
This will make it easier to break main() up into pieces too.
Also, note that some of the regexes are for x86-specific asm.

Not thrilled with how it handles the stack manipulation logic, but I'm
much less bothered by that than I am by updating the test manually. =]
If anyone wants to teach the test checks management script about stack
adjustment patterns, that'd be cool too.

This is done in a bit of a strange way to use a multiline RE instead of
looping over the lines. Suggestions welcome here for a more pythonic way
of doing this as long as its reasonably fast.

with 'stress' to indicate that the specific output isn't interesting and
relax them to only check the last instruction (a ret).
I've updated the one test case that really uses this to name the one
'stress_test' which was actually producing output we can directly check.
With this, the script doesn't introduce noise when run over the v16 test
file.

This script is currently specific to x86 and limited to use with very
small regression or feature tests using 'llc' and 'FileCheck' in
a reasonably canonical way. It is in no way general purpose or robust at
this point. However, it works quite well for simple examples. Here is
the intended workflow:
- Make a change that requires updating N test files and M functions'
assertions within those files.
- Stash the change.
- Update those N test files' RUN-lines to look "canonical"[1].
- Refresh the FileCheck lines for either the entire file or select
functions by running this script.
- The script will parse the RUN lines and run the 'llc' binary you
give it according to each line, collecting the asm.
- It will then annotate each function with the appropriate FileCheck
comments to check every instruction from the start of the first
basic block to the last return.
- There will be numerous cases where the script either fails to remove
the old lines, or inserts checks which need to be manually editted,
but the manual edits tend to be deletions or replacements of
registers with FileCheck variables which are fast manual edits.
- A common pattern is to have the script insert complete checking of
every instruction, and then edit it down to only check the relevant
ones.
- Be careful to do all of these cleanups though! The script is
designed to make transferring and formatting the asm output of llc
into a test case fast, it is *not* designed to be authoratitive
about what constitutes a good test!
- Commit the nice fresh baseline of checks.
- Unstash your change and rebuild llc.
- Re-run script to regenerate the FileCheck annotations
- Remember to re-cleanup these annotations!!!
- Check the diff to make sure this is sane, checking the things you
expected it to, and check that the newly updated tests actually pass.
- Profit!
Also, I'm *terrible* at writing Python, and frankly I didn't spend a lot
of time making this script beautiful or well engineered. But it's useful
to me and may be useful to others so I thought I'd send it out.
