Bug ID: 89099
Summary: Have "-fopt-info" show the original source code
context
Product: gcc
Version: 9.0
Status: UNCONFIRMED
Keywords: diagnostic
Severity: enhancement
Priority: P3
Component: middle-end
Assignee: unassigned at gcc dot gnu.org
Reporter: tschwinge at gcc dot gnu.org
Target Milestone: ---
It would be useful to have "-fopt-info" show the original source code context.
For example, we've got diagnostics like:
[...]/asyncwait-1.c: In function 'main':
[...]/asyncwait-1.c:14:11: warning: unused parameter 'argc'
[-Wunused-parameter]
14 | main (int argc, char **argv)
| ~~~~^~~~
..., but "-fopt-info" only prints a terse form:
[...]
[...]/asyncwait-1.c:480:9: optimized: assigned OpenACC gang loop
parallelism
[...]
... without showing any of the original source code context.
This should be enabled by default, if possible, but disabled by some flag (can
just use "-fno-diagnostics-show-caret" here, too?).
