-fdebug-prefix-map=: make the last win when multiple prefixes match

2023-04-25T22:12:17+00:00

For
`clang -c -g -fdebug-prefix-map=a/b=y -fdebug-prefix-map=a=x a/b/c.c`,
we apply the longest prefix substitution, but
GCC has always been picking the last applicable option (`a=x`, see
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=109591).

I feel that GCC's behavior is reasonable given the convention that the last
value wins for the same option.

Before D49466, Clang appeared to apply the shortest prefix substitution,
which likely made the least sense.

reland: [clang] Don't append the working directory to absolute paths

2022-03-15T20:42:35+00:00

This fixes a bug that happens when using -fdebug-prefix-map to remap an
absolute path to a relative path. Since the path was absolute before
remapping, it is safe to assume that concatenating the remapped working
directory would be wrong.

This was originally submitted as https://reviews.llvm.org/D113718, but
reverted because when testing with dwarf 5 enabled, the tests were too
strict.

[clang] Fix DIFile directory root on Windows

2022-03-15T03:07:01+00:00

On unix systems this logic would not separate the file and directory of
the DIFile unless they shared more components at the start than just the
root path character. The logic to do this was unix specific so it didn't
work on Windows. Now we check if the entire root_path is the same as
what you were going to set as the Dir and use the full filepath in that
case.

Use functions with prototypes when appropriate; NFC

2022-02-15T21:06:43+00:00

A significant number of our tests in C accidentally use functions
without prototypes. This patch converts the function signatures to have
a prototype for the situations where the test is not specific to K&R C
declarations. e.g.,

  void func();

becomes

  void func(void);

This is the eleventh batch of tests being updated (there are a
significant number of other tests left to be updated).

Allow remapping the sysroot with -fdebug-prefix-map.

Fix tests on Windows after D49466

2019-11-27T00:15:39+00:00

It is tricky to use replace_path_prefix correctly on Windows which uses
backslashes as native path separators. Switch back to the old approach
(startswith is not ideal) to appease build bots for now.
