[PATCH] D36020: [llvm-cov] Unify region marker placement between text/html modes

[Vedant Kumar via Phabricator via llvm-commits]

vsk created this revision.

Make sure that the text and html emitters always emit the same set of
region markers, and avoid emitting redundant markers for line segments
which don't end on the line they start on.

Here is the html output from the deferred-region.cpp test:
F3813435: region-markers.html <https://reviews.llvm.org/F3813435>

This is related to https://reviews.llvm.org/D35925, and depends on https://reviews.llvm.org/D36014
