Bug ID: 31395
Summary: llvm-cov report filtering without function coverage
display
Product: clang
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: -New Bugs
Assignee: unassignedclangb...@nondot.org
Reporter: d...@mapbox.com
CC: llvm-bugs@lists.llvm.org
Classification: Unclassified
I've noticed that `llvm-cov report` shows per-file summaries when no source
files are passed. But when source files are passed, it seems to automatically
go into a new mode where per-function summaries are displayed. I think it would
be more ideal if function summaries were only enabled via an option. The reason
I think it would be better as an option is for the case where:
1. You want to filter out which source files contribute to the summary, but..
2. You don't want to see per-function output
Currently this appears not possible: you can't get per-function summary output
without manually passing source files. And you can't get per-file summary
output if you manually pass source files.
Here is a demonstration of the two modes
(https://gist.github.com/springmeyer/b5a46888bd330f42f6430d9b78a54ca3). The
first is too verbose due to the function-summaries, and the latter is too
verbose due to dependency headers being included in the coverage report that
are not important.
