* Add cmakefiles to build profile_rt.so!Nick Lewycky2011-04-26
| | | | git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@130191 91177308-0d34-0410-b5e6-96231b3b80d8
* 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
