assertEquals is a deprecated alias for assertEqual and has been removed
in Python 3.12. This wasn't an issue previously because we used a
vendored version of the unittest module. Now that we use the built-in
version this gets updated together with the Python version used to run
the test suite.
This is an ongoing series of commits that are reformatting our Python
code. Reformatting is done with `black` (23.1.0).
If you end up having problems merging this commit because you have made
changes to a python file, the best way to handle that is to run `git
checkout --ours <yourfile>` and then reformat it with black.

I went over the output of the following mess of a command:
(ulimit -m 2000000; ulimit -v 2000000; git ls-files -z | parallel
--xargs -0 cat | aspell list --mode=none --ignore-case | grep -E
'^[A-Za-z][a-z]*$' | sort | uniq -c | sort -n | grep -vE '.{25}' |
aspell pipe -W3 | grep : | cut -d' ' -f2 | less)
and proceeded to spend a few days looking at it to find probable typos
and fixed a few hundred of them in all of the llvm project (note, the
ones I found are not anywhere near all of them, but it seems like a
good start).

Given that you'd never find empty string, just error.

This reverts commit 859ebca744e634dcc89a2294ffa41574f947bd62.
The change contained many unrelated changes and e.g. restored
unit test failes for the old lld port.
This reverts commit 640beb38e7710b939b3cfb3f4c54accc694b1d30.
That commit caused performance degradtion in Quicksilver test QS:sGPU and a functional test failure in (rocPRIM rocprim.device_segmented_radix_sort).
Reverting until we have a better solution to s_cselect_b64 codegen cleanup

This adds a new command for writing memory tags.
It is based on the existing "memory write" command.
Syntax: memory tag write <address-expression> <value> [<value> [...]]
(where "value" is a tag value)
(lldb) memory tag write mte_buf 1 2
(lldb) memory tag read mte_buf mte_buf+32
Logical tag: 0x0
Allocation tags:
[0xfffff7ff9000, 0xfffff7ff9010): 0x1
[0xfffff7ff9010, 0xfffff7ff9020): 0x2
The range you are writing to will be calculated by
aligning the address down to a granule boundary then
adding as many granules as there are tags.
(a repeating mode with an end address will be in a follow
up patch)
This is why "memory tag write" uses MakeTaggedRange but has
some extra steps to get this specific behaviour.
The command does all the usual argument validation:
* Address must evaluate
* You must supply at least one tag value
(though lldb-server would just treat that as a nop anyway)
* Those tag values must be valid for your tagging scheme
(e.g. for MTE the value must be > 0 and < 0xf)
* The calculated range must be memory tagged
That last error will show you the final range, not just
the start address you gave the command.
(lldb) memory tag write mte_buf_2+page_size-16 6
(lldb) memory tag write mte_buf_2+page_size-16 6 7
error: Address range 0xfffff7ffaff0:0xfffff7ffb010 is not in a memory tagged region
(note that we do not check if the region is writeable
since lldb can write to it anyway)
The read and write tag tests have been merged into
a single set of "tag access" tests as their test programs would
have been almost identical.
(also I have renamed some of the buffers to better
show what each one is used for)

This corrects the test added in
31f9960c38529ce805edf9764535eb0ce188cadf
and temporarily patched in
3b4aad1186e8e8e6f6c7887cb5e8d9bfd7d3ce2f.
This test checks that the memory tag read
command errors when you use it on a platform
without memory tagging.
(which is why we skip the test if you actually
have MTE)
The problem with this test is that there's
two levels of unsupported each with it's own
specific error.
On anything that isn't AArch64, there's no
tagging extension we support. So you're told
that that is the case. As in "this won't ever work".
When you're on AArch64 we know that MTE could
be present on the remote and when we find that it
isn't, we tell you that instead.
Expect a different error message on AArch64 to fix
the test.
This new command looks much like "memory read"
and mirrors its basic behaviour.
(lldb) memory tag read new_buf_ptr new_buf_ptr+32
Logical tag: 0x9
Allocation tags:
[0x900fffff7ffa000, 0x900fffff7ffa010): 0x9
[0x900fffff7ffa010, 0x900fffff7ffa020): 0x0
Important proprties:
* The end address is optional and defaults to reading
1 tag if ommitted
* It is an error to try to read tags if the architecture
or process doesn't support it, or if the range asked
for is not tagged.
* It is an error to read an inverted range (end < begin)
(logical tags are removed for this check so you can
pass tagged addresses here)
* The range will be expanded to fit the tagging granule,
so you can get more tags than simply (end-begin)/granule size.
Whatever you get back will always cover the original range.

Summary:
Around a third of our test sources have LLVM license headers. This patch removes those headers from all test
sources and also fixes any tests that depended on the length of the license header.
The reasons for this are:
* A few tests verify line numbers and will start failing if the number of lines in the LLVM license header changes. Once I landed my patch for valid SourceLocations in debug info we will probably have even more tests that verify line numbers.
* No other LLVM project is putting license headers in its test files to my knowledge.
* They make the test sources much more verbose than they have to be. Several tests have longer license headers than the actual test source.
For the record, the following tests had their line numbers changed to pass with the removal of the license header:

Summary:
The error message from the construct `assertTrue(a == b, "msg") ` are nearly always completely useless for actually debugging the issue.
This patch is just replacing this construct (and similar ones like `assertTrue(a != b, ...)` with the proper call to assertEqual or assertNotEquals.
This patch was mostly written by a shell script with some manual verification afterwards:
```
lang=python
import sys
def sanitize_line(line):
if line.strip().startswith("self.assertTrue(") and " == " in line:
line = line.replace("self.assertTrue(", "self.assertEquals(")
line = line.replace(" == ", ", ", 1)
if line.strip().startswith("self.assertTrue(") and " != " in line:
line = line.replace("self.assertTrue(", "self.assertNotEqual(")
line = line.replace(" != ", ", ", 1)
return line
for a in sys.argv[1:]:
with open(a, "r") as f:
lines = f.readlines()
with open(a, "w") as f:
for line in lines:
f.write(sanitize_line(line))
