[Coverage] Use the wrapped segment when a line has entry segments We've worked around bugs in the frontend by ignoring the count from wrapped segments when a line has at least one region entry segment. Those frontend bugs are now fixed, so it's time to regenerate the checked-in covmapping files and remove the workaround. llvm-svn: 317761

[llvm-cov] Warn if -show-functions is used without query files llvm-cov's report mode does not print any output when -show-functions is specified and no source files are specified. This can be surprising, so the tool should at least print out an error message when this happens. rdar://problem/34636859 llvm-svn: 314175

llvm-cov: Use the number of executed functions for the function coverage metric. This commit fixes llvm-cov's function coverage metric by using the number of executed functions instead of the number of fully covered functions. Differential Revision: http://reviews.llvm.org/D5196 llvm-svn: 218672

[llvm-cov] Track function and instantiation coverage separately These are distinct statistics which are useful to look at separately. Example: say you have a template function "foo" with 5 instantiations and only 3 of them are covered. Then this contributes (1/1) to the total function coverage and (3/5) to the total instantiation coverage. I.e, the old "Function Coverage" column has been renamed to "Instantiation Coverage", and the new "Function Coverage" aggregates information from the various instantiations of a function. One benefit of making this switch is that the Line and Region coverage columns will start making sense. Let's continue the example and assume that the 5 instantiations of "foo" cover {2, 4, 6, 8, 10} out of 10 lines respectively. The new line coverage for "foo" is (10/10), not (30/50). The old scenario got confusing because we'd report that there were more lines in a file than what was actually possible. llvm-svn: 281875

[llvm-cov] Minor cleanups to prepare for the html format patch - Add renderView{Header,Footer}, renderLineSuffix, and hasSubViews to support creating tables with nested views. - Move the 'Format' cl::opt to make it easier to extend. - Just create one function view file, instead of overwriting the same file for every new function. Add a regression test for this. llvm-svn: 274086
