* Add support for line profiling. Very work-in-progress.Nick Lewycky2011-04-12
| | | | | | | | | | | Use debug info in the IR to find the directory/file:line:col. Each time that location changes, bump a counter. Unlike the existing profiling system, we don't try to look at argv[], and thusly don't require main() to be present in the IR. This matches GCC's technique where you specify the profiling flag when producing each .o file. The runtime library is minimal, currently just calling printf at program shutdown time. The API is designed to make it possible to emit GCOV data later on. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129340 91177308-0d34-0410-b5e6-96231b3b80d8
* Implementation of path profiling.Andrew Trick2011-01-29
| | | | | | | | | | | Modified patch by Adam Preuss. This builds on the existing framework for block tracing, edge profiling and optimal edge profiling. See -help-hidden for new flags. For documentation, see the technical report "Implementation of Path Profiling..." in llvm.org/pubs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@124515 91177308-0d34-0410-b5e6-96231b3b80d8
