75b29335ab [flang] Clean out obsolete parsing code. Handle !cdir$ fixed and free in parser.
Work on scanning compiler directive lines.

Fix glitch in earlier change to parse-state.h.

Add ClassifyLine(), simplify some token sequence data lifetimes and interfaces.

Handle continued directives.  Obey !DIR$ FIXED and FREE in prescanner.

Some refactoring of TokenSequence API, then support initial directives (FIXED, FREE, IGNORE_TKR).

Fix !DIR$ IGNORE_TKR syntax, manual was wrong.

Debugging directive scanning & parsing.

Profiling-directed speed-up - do not map cooked source locations to Provenance until a Message is emitted.  Turn some non-nullable pointers into references.

Debugging.

Handle !DIR$ IVDEP too, it is in a test.

Accept directives in the execution part.

424ec7b35b [flang] Handle empty files gracefully.
Create interval.h.  Use std::size_t instead of bare size_t.  Redefine parser::Name to not be just a bare string.

Break out and rename CharBlock from token-sequence.h for use in the parse tree.

Incremental replacement of name strings with pointers to cooked characters.

Fix case sensitivity problem.

Use new CharBlock encoding to replace strings for real literal constants.

Normalized cooked character stream to lower case.

Simplify parsing now that cooked stream is lower case.  Replace Keyword in parse tree.

Add static_asserts to || and recovery parsers to enforce same result types.

Remove needless TODO comment inserted earlier.

Fix case conversion on prefixed character literals (f90_correct/dc04.f90).

Use CharBlock in user-state.h.

Complete transition from nextChar to nextCh (i.e., always use pointers).

Document extensions.  Begin work on compiler directive lines.

More documentation work.

Reformat prescan.cc.

More work on compiler directive scanning.

79d044e9b5 [flang] Take flang-compiler/f18#2 on unparsing, now using the new parse tree walker.
Clean out old data structure formatter.

Create stand-alone Parsing class to compose parts of the parser together.

Hello, world!

Better error recovery on command line errors.

Fix bugs from initial run at f77_correct.

Allow parentheses on PROGRAM statement.

Fix Hollerith scanning.

Remove REDIMENSION with good error recovery.

Fix new "spaces" parser, clean up calls to it.

Fix bugs exposed by in38.f90.

Escaped \a is not special to pgf90; get slashes around STRUCTURE name right.

Better multi-byte source encoding support in Hollerith.

Reformat C++.

More work on multi-byte source encoding.

Pass 219 tests in f77_correct, with good excuses for the rest.

Add omitted DIRECT= and UNFORMATTED= specifiers to INQUIRE statement.
Add Interval<>, rebase ProvenanceRange upon it, rebase CharPointerWithLength
and rename it ContiguousChars.

03aecfc336 [flang] Preserve some minor changes that accumulated as I was implementing
an unparsing feature.

Enum classes in parse tree node class types are now defined with
a macro so that the names of the enumerations can be captured for
formatting purposes.

Add a TODO comment.

Rebase to new master with parse tree traversal code.
