Why does __gcov_flush only flush the current compilation unit? For gcc __gcov_flush flushes all of the loaded files. Is there a way to have __gcov_flush flush everything? -- John Harrison On Wed, Feb 6, 2013 at 10:24 AM, John Harrison <ash.gti at gmail.com> wrote: > Ah, my mistake. So this already works. I...

Yikes! It only flushes the counts for the current compilation unit? That sounds like a terrible bug. Can you file a bugzilla report, please?

The way `-ftest-coverage -fprofile-arcs` works at the moment it only flushes via `atexit()`. This patch allows you to flush the coverage at any point by calling `__llvm_gcov_flush` the same way `__gcov_flush` works for gcc. If there is another way of doing this, I might of missed it but I was looking for `__gcov_flush` and I did not find the equivalent in llvm at the moment. -- John Harrison On Tue, Feb 5, 2013 at 11:26 PM, Bill Wendling <wendling at apple.com> wrote: > We do have a gcov...

...ture request that you cannot flush gcov buffers while the app is running. They are only called when you exit the program, since the flush functions are registered with atexit(). This is the bug report: http://llvm.org/bugs/show_bug.cgi?id=12144 I have what I think is a basic implementation of the `__gcov_flush` call, although I called this version `__llvm_gcov_flush`. Here is the diff https://gist.github.com/ashgti/4685743 if anyone would like to see it. So, my question is where should I go from here? Do I need to email the exact patch to llvm-commits? This touches both the llvm and compiler-rt, so I do...

...should be declared as hidden, i.e. symbols that are not exported by shared libraries. This would allow the GCDA based profiling to work correctly with code using dlopen/dlclose to load and unload shared libraries. Each shared library must have its own copy of the following GCDA functions: - __gcov_flush - llvm_delete_flush_function_list - llvm_delete_writeout_function_list - llvm_gcda_emit_arcs - llvm_gcda_emit_function - llvm_gcda_end_file - llvm_gcda_increment_indirect_counter - llvm_gcda_start_file - llvm_gcda_summary_info - llvm_gcov_init - llv...

Updated set of patches for coverage. Changes: - change copyright lines - use gcov: instead of cover: in commit comment - use #ifdef in xen/common/sysctl.c instead of dummy inline function - added base documentation in docs/misc - added -h option to xencov
