Richard SmithandJon Meow e85f45de10 Move CHECK lines in tests next to the line that caused the output. (#1224) 
Use FileCheck's `[[@LINE+n]]` mechanism to refer to the next line.

This is made awkward by a couple of things:

* We want to keep the `CHECK` lines in the original order.
* Errors are sometimes more than one line long.

The approach we use is to interleave the original lines and the check lines, putting each check line as early as possible subject to two rules:

1) Check lines never precede the 'AUTOUPDATE' line
2) Except when required by rule (1), a check line that refers to a source line by line number is never placed earlier than a source line that precedes that source line.

The actual `[[@LINE+n]]` annotations are created in a second pass after we've interleaved the lines so that we can work out the correct offsets.

Jon Meow b87747306f Add the ability to pipe trace output to a file. (#1183) 
Breaks `--trace` into two flags:

- `--parser_debug`, which sets the parser debug level (which I haven't dug into piping with `--trace`, but seemed likely to be troublesome)
- `--trace_file`, which now the type checker and interpreter will use for trace information (note compile errors should use a different channel)

Most of the file edits are just mechanical testdata flag updates: `sed -i 's/--trace/--parser_debug --trace_file=-/' testdata/**/*.carbon`

To explain the output paths:

- parse/compile errors: stderr
- print() calls: stdout
- parser tracing: `--parser_debug` option, stdout (formerly stdout if `--trace`)
- type check/compile tracing: `--trace_file=<file>`, giving `-` uses stdout (formerly stdout if `--trace`)
- return code of executed Carbon code: `--trace_file` if set, stdout if not (formerly stdout always)

Geoff Romer f75b4d322f Handle use-before-declare in static name lookup (#967) 
Also remove inheritance from NamedEntity for some classes that don't need it.

Geoff RomerandJon Meow 17e0a1afb9 Implement static name resolution (#958) 
This doesn't actually use the results of name resolution, but it does verify that they are present.
Also ensures that name resolution and type checking are applied to deduced function parameters and the implicit call to `Main()`.

Geoff Romer b14c97d0d7 Clean up remaining uses of old spelling main (#959) 2021-11-24 14:32:39 -08:00
Chandler Carruth b990bab452 Fix main names that got past CI to fix tests. (#945) 
#939 switch to `Main`, but #919 predated it and didn't get updated
before merging. Its tests passed on the PR branch as a consequence, but
failed when landed.

This just updates the test cases. Trivial fix forward.

Jon MeowandGeoff Romer 27e084d37a Start populating named entities in relevant locations. (#919) 
This starts detecting naming collisions as a consequence of being able to determine when the name is declared twice in a given scope.
