diff_plist"
Following r363007, which reverted r362998, r362996, and r362994,
reapply with adjustments for the CRLF differences encountered with
Windows. Namely, the `-b` option of `diff` is employed, and the `grep`
patterns have `$` replaced with `[[:space:]]*$`.

diff_plist"
Reverts r362998, r362996, and r362994 because the tests do not pass on
Windows due to CRLF changes. Adding back `-w` to diff is not enough, the
new grep substitution doesn't work on Windows, and fixing it is
non-trivial.

Summary:
The `%diff_plist` lit substitution invokes `diff` with a non-portable
`-I` option. The intended effect can be achieved by normalizing the
inputs to `diff` beforehand. Such normalization can be done with
`grep -Ev`, which is also used by other tests.
This patch applies the change (adjusted for review comments) described
in http://lists.llvm.org/pipermail/cfe-dev/2019-April/061904.html
mechanically to the cases where the output file is piped to
`%diff_plist` via `cat`.
The changes were applied via a script, except that
`clang/test/Analysis/NewDelete-path-notes.cpp` and
`clang/test/Analysis/plist-macros-with-expansion.cpp` were each adjusted
for the line-continuation on the relevant `RUN` step.

The current argument order has "expected" and "actual" the wrong way around,
so that the diff shows the change from expected to actual, not from actual to expected.
Namely, if the expected diagnostics contains the string "foo", but the analyzer emits "bar",
we really want to see:
```
- foo
+ bar
```
not
```
- bar
+ foo
```
since adapting to most changes would require applying that diff to the expected output.

files, use diff instead of a FileCheck
Some of the analyzer tests check the exact plist output, in order to
verify that the diagnostics produced is correct.
Current testing setup has many issues:
plist output clobbers tests, making them harder to read
it is impossible to debug test failures given error messages from FileCheck.
The only recourse is manually creating the files and using the diff
again, it is impossible to update the tests given the error message:
the only process is a tedious manual one,
going from a separate plist file to CHECK directives.
This patch offers a much better approach of using "diff" directly in place of FileCheck,
and moving tests to separate files.
Generated using the following script:
```
import os
import glob
import re
import subprocess
diagnostics_key = "// CHECK: <key>diagnostics</key>"
def process_file(f, data):
idx = data.index(diagnostics_key)
plist_out_f = 'ExpectedOutputs/plists/%s.plist' % f
plist_out_folder = os.path.join('ExpectedOutputs/plists/', os.path.dirname(f))
plist_data = data[idx:]
plist_data = plist_data.replace('// CHECK: ', '')
plist_data = plist_data.replace('// CHECK-NEXT: ', '')
plist_data += "</dict>\n</plist>\n"
data = data[:idx]
ptn = re.compile("FileCheck --?input-file(=| )(%t|%t\.plist) %s")
if not ptn.findall(data):
print "none found =/ skipping..."
return
data = ptn.sub(lambda m: "tail -n +11 %s | diff -u -w - %%S/../%s" % (m.group(2), plist_out_f), data)
with open(f, 'w') as out_f:
out_f.write(data)
subprocess.check_call(["mkdir", "-p", plist_out_folder])
with open(plist_out_f, 'w') as out_f:
out_f.write(plist_data)
def main():
files = glob.glob("**/*.*")
for f in files:
with open(f) as f_handler:
data = f_handler.read()
if diagnostics_key in data:
print "Converting %s" %f
process_file(f, data)
if __name__ == "__main__":
main()

Note diagnostic pieces are an additional way of highlighting code sections to
the user. They aren't part of the normal path diagnostic sequence. They can
also be attached to path-insensitive reports.
Notes are already supported by the text output and scan-build.
Expanding our machine-readable plist output format to be able to represent notes
opens up the possibility for various analyzer GUIs to pick them up.

Summary:
So far we used a value of 10 which was useful for testing but produces many false-positives in real programs. The usual suspicious clones we find seem to be at around a complexity value of 70 and for normal clone-reporting everything above 50 seems to be a valid normal clone for users, so let's just go with 50 for now and set this as the new default value.
This patch also explicitly sets the complexity value for the regression tests as they serve more of a regression testing/debugging purpose and shouldn't really be reported by default in real programs. I'll add more tests that reflect actual found bugs that then need to pass with the default setting in the future.

llvm-svn: 283182

|
Highlight code clones referenced by the warning message with the help of
the extra notes feature recently introduced in r283092.
Change warning text to more clang-ish. Remove suggestions from the copy-paste
error checker diagnostics, because currently our suggestions are strictly 50%
wrong (we do not know which of the two code clones contains the error), and
for that reason we should not sound as if we're actually suggesting this.
Hopefully a better solution would bring them back.
Make sure the suspicious clone pair structure always mentions
the correct variable for the second clone.
