#file includes an entire gigantic path whenever it is used, and it is often used implicitly. This has two negative effects: It wastes space on something that is almost never needed and it invisibly embeds information in the binary, such as the developer's username, that they may want to keep private.

This PR changes the behavior of #file so that it evaluates to a short string containing the module name and filename, but not the full path. It also adds #filePath, which continues to give you the absolute path.

These changes are hidden behind a feature flag, -enable-experimental-concise-pound-file, because making them permanent will require an evolution proposal.

This change includes some basic tests with the flag enabled, but they're not comprehensive; for instance, code completion isn't tested anywhere. The implementation for the proposal should update existing #file tests and add matching #filePath tests to ensure adequate coverage.

Progresses towards fixing rdar://problem/56816166.

How to read the data The tables contain differences in performance which are larger than 8% and differences in code size which are larger than 1%.

If you see any unexpected regressions, you should consider fixing the
regressions before you merge the PR.

Noise: Sometimes the performance results (not code size!) contain false
alarms. Unexpected regressions which are marked with '(?)' are probably noise.
If you see regressions which you cannot explain you can try to run the
benchmarks again. If regressions still show up, please consult with the
performance team (@eeckstein).

Okay, "up to 6% code size" is probably a fair summary of that. Let's try compiler performance and look at number of bytes output as a rough proxy for code size of the source compatibility suite.

@swift-ci please test compiler performance

macOS test failures are examples of the feature working correctly, but affecting tests I didn't update. I'm not sure why they didn't run locally. 🤷‍♂️

How to read the data The tables contain differences in performance which are larger than 8% and differences in code size which are larger than 1%.

If you see any unexpected regressions, you should consider fixing the
regressions before you merge the PR.

Noise: Sometimes the performance results (not code size!) contain false
alarms. Unexpected regressions which are marked with '(?)' are probably noise.
If you see regressions which you cannot explain you can try to run the
benchmarks again. If regressions still show up, please consult with the
performance team (@eeckstein).

The test failure is because I need to re-gyb SwiftSyntax files.

@beccadax
Make #file only include the filename
1e9d3b7 
This change may have significant code size benefits.
@beccadax
Include module name in string
e5b582f 
Along with a not-yet-usable way to get back to the old behavior.
@beccadax
Control #file behavior with a command line option
789d38e
@beccadax
Turn new #file behavior off by default
44a2f67
@beccadax
Flip default in test
2acaf38
@beccadax
Introduce a separate #filePath, remove -pound-file
63ec1cf 
This makes the path behavior more first-class. The feature is now hidden behind an experimental flag, -enable-experimental-concise-pound-file.
@beccadax beccadax changed the title Add command-line flag to shorten #file Shorten #file and add #filePath (behind an experimental flag) Dec 5, 2019
