* Profile: move a single enum out of ProfileInfoTypes.h into a new Manman Ren2012-08-24
| | | | | | | | | | | | | ProfileDataTypes.h header. With this patch the old and new profiling code can exist side-by-side. The new profiling code will be submitted soon and it only supports insert-edge-profiling for now and will not depend on ProfileInfo.

Implement GCOV_PREFIX. Doesn't handle GCOV_PREFIX_STRIP yet. Fix an off-by-one in string emission. Extra whoops! Tolerate DISubprograms that have null Function*'s attached to them. I don't yet understand what this means, but it happens when you have a global static with a non-trivial constructor/destructor.

* Rename everything to follow LLVM style ... I think.Nick Lewycky2011-04-26
| | | | | | | | | | | | | | | Add support for switch and indirectbr edges. This works by densely numbering all blocks which have such terminators, and then separately numbering the possible successors. The predecessors write down a number, the successor knows its own number (as a ConstantInt) and sends that and the pointer to the number the predecessor wrote down to the runtime, who looks up the counter in a per-function table. Coverage data should now be functional, but I haven't tested it on anything other than my 2-file synthetic test program for coverage. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@130186 91177308-0d34-0410-b5e6-96231b3b80d8

* 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.
