Use `Freeze` for `SourceFile.lines`

Use relative positions inside a SourceFile.

Avoid unnecessary line lookup.

2023-06-29T01:26:39+00:00

`lookup_debug_loc` calls `SourceMap::lookup_line`, which does a binary search over the files, and then a binary search over the lines within the found file. It then calls `SourceFile::line_begin_pos`, which redoes the binary search over the lines within the found file. This commit removes the second binary search over the lines, instead getting the line starting pos directly using the result of the first binary search over the lines. (And likewise for `get_span_loc`, in the cranelift backend.)

Fix `rustdoc --version` when used with download-rustc

2022-11-09T08:54:51+00:00

Previously, rustdoc would unconditionally report the version that *rustc* was compiled with. That showed things like `nightly-2022-10-30`, which wasn't right, since this was a `dev` build compiled from source. Fix it by changing `rustc_driver::version` to a macro expanded at invocation time.

ssa: implement `#[collapse_debuginfo]`

2022-09-07T12:54:51+00:00

Debuginfo line information for macro invocations are collapsed by default - line information are replaced by the line of the outermost expansion site. Using `-Zdebug-macros` disables this behaviour. When the `collapse_debuginfo` feature is enabled, the default behaviour is reversed so that debuginfo is not collapsed by default. In addition, the `#[collapse_debuginfo]` attribute is available and can be applied to macro definitions which will then have their line information collapsed. Signed-off-by: David Wood
