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] Fix issues with segment highlighting in the html view The text and html coverage views take different approaches to emitting highlighted regions. That's because this problem is easier in the text view: there's no need to worry about escaping text or adding tooltip content to a highlighted snippet. Unfortunately, the html view didn't get region highlighting quite right. This patch fixes the situation, bringing parity between the two views. llvm-svn: 280981

Retry: [llvm-cov] Add support for exporting coverage data to JSON This enables users to export coverage information as portable JSON for use by analysis tools and storage in document based databases. The export sub-command is invoked just like the others: llvm-cov export -instr-profile path/to/foo.profdata path/to/foo.binary The resulting JSON contains a list of files and functions. Every file object contains a list of segments, expansions, and a summary of the file's region, function, and line coverage. Every function object contains the function's name and regions. There is also a total summary for the entire object file. Changes since the initial commit (r276813): - Fixed the regexes in the tests to handle Windows filepaths. Patch by Eddie Hurtig!
