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] Ignore unclosed line segments when setting line counts This patch makes a slight change to the way llvm-cov determines line execution counts. If there are multiple line segments on a line, the line count is the max count among the regions which start *and* end on the line. This avoids an issue posed by deferred regions which start on the same line as a terminated region, e.g: if (false) return; //< The line count should be 0, even though a new region //< starts at the semi-colon. foo(); Another change is that counts from line segments which don't correspond to region entries are considered. This enables the first change, and corrects an outstanding issue (see the showLineExecutionCounts.cpp test change). This is related to D35925.

[llvm-cov] Add an option which maps the location of source directories on another machine to your local copies Summary: This patch adds the -path-equivalence option (example: llvm-cov show -path-equivalence=/origin/path,/local/path) which maps the source code path from one machine to another when using `llvm-cov show`. This is similar to the -filename-equivalence option, but doesn't require you to specify all the source files on the command line. This allows you to generate the coverage data on one machine (e.g. in a CI system), and then use llvm-cov on another machine where you have the same code base on a different path.

Reapply "[llvm-cov] Add an -output-dir option for the show sub-command"" Passing -output-dir path/to/dir to llvm-cov show creates path/to/dir if it doesn't already exist, and prints reports into that directory. In function view mode, all views are written into path/to/dir/functions.$EXTENSION. In file view mode, all views are written into path/to/dir/coverage/$PATH.$EXTENSION.
