InstrProf: Use the proftext format for these coverage tests This format's easier to understand and update by hand. llvm-svn: 231686

llvm-cov: add code coverage tool that's based on coverage mapping format and clang's pgo. This commit expands llvm-cov's functionality by adding support for a new code coverage tool that uses LLVM's coverage mapping format and clang's instrumentation based profiling. The gcov compatible tool can be invoked by supplying the 'gcov' command as the first argument, or by modifying the tool's name to end with 'gcov'.

[llvm-cov] Unify region marker placement between text/html modes 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. This is related to D35925, and depends on D36014 Differential Revision: https://reviews.llvm.org/D36020 llvm-svn: 312813

[llvm-cov] Suppress sub-line highlights in simple cases llvm-cov tends to highlight too many regions because its policy is to highlight all region entry segments. This can look confusing to users: not all region entry segments are interesting and deserve highlighting. Emitting these highlights only when the region count differs from the line count is a more user-friendly policy. llvm-svn: 316109

InstrProf: Fix display of large numbers in llvm-cov llvm-cov was truncating numbers that were larger than a particular fixed width, which is as confusing as it is useless. Instead, we use engineering notation with SI prefix for magnitude. llvm-svn: 237307
