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

// Basic handling of line counts.

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'.

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

llvm-cov: Only emit colour by default if the output is a tty This replaces the -no-color flag with a -color={auto|always|never} option, with auto as the default, which is much saner. llvm-svn: 232693
