* Don't use a red zone for code coverage if the user specified `-mno-red-zone'.Bill Wendling2012-12-101-4/+17
| | | | | | | | | The `-mno-red-zone' flag wasn't being propagated to the functions that code coverage generates. This allowed some of them to use the red zone when that wasn't allowed. <rdar://problem/12843084> llvm-svn: 169754
* Use the new script to sort the includes of every file under lib.Chandler Carruth2012-12-031-6/+6
| | | | | | | | | | | | | | | | | Sooooo many of these had incorrect or strange main module includes. I have manually inspected all of these, and fixed the main module include to be the nearest plausible thing I could find. If you own or care about any of these source files, I encourage you to take some time and check that these edits were sensible. I can't have broken anything (I strictly added headers, and reordered them, never removed), but they may not be the headers you'd really like to identify as containing the API being implemented. Many forward declarations and missing includes were added to a header files to allow them to parse cleanly when included first. The main module rule does in fact have its merits. =] llvm-svn: 169131

* Introduce the __llvm_gcov_flush function.Bill Wendling2012-09-131-6/+56
| | | | | | | | | | This function writes out the current values of the counters and then resets them. This can be used similarly to the __gcov_flush function to sync the counters when need be. For instance, in a situation where the application doesn't exit. <rdar://problem/12185886> llvm-svn: 163757

* Move llvm/Support/IRBuilder.h -> llvm/IRBuilder.hChandler Carruth2012-06-291-9/+9
| | | | | | | | | | | | | | | | | This was always part of the VMCore library out of necessity -- it deals entirely in the IR. The .cpp file in fact was already part of the VMCore library. This is just a mechanical move. I've tried to go through and re-apply the coding standard's preferred header sort, but at 40-ish files, I may have gotten some wrong. Please let me know if so. I'll be committing the corresponding updates to Clang and Polly, and Duncan has DragonEgg. Thanks to Bill and Eric for giving the green light for this bit of cleanup. llvm-svn: 159421
* Move lib/Analysis/DebugInfo.cpp to lib/VMCore/DebugInfo.cpp andBill Wendling2012-06-281-1/+1
| | | | | | | | | include/llvm/Analysis/DebugInfo.h to include/llvm/DebugInfo.h. The reasoning is because the DebugInfo module is simply an interface to the debug info MDNodes and has nothing to do with analysis. llvm-svn: 159312
* Extend the IL for selecting TLS models (PR9788)Hans Wennborg2012-06-231-1/+1
| | | | | | | | | | | | | | | This allows the user/front-end to specify a model that is better than what LLVM would choose by default. For example, a variable might be declared as @x = thread_local(initialexec) global i32 42 if it will not be used in a shared library that is dlopen'ed. If the specified model isn't supported by the target, or if LLVM can make a better choice, a different model may be used. llvm-svn: 159077
* Register the gcov "writeout" at init time. Don't list this as a d'tor. Instead,Bill Wendling2012-06-011-2/+22
| | | | | | | | | | | | inject some code in that will run via the "__mod_init_func" method that registers the gcov "writeout" function to execute at exit time. The problem is that the "__mod_term_func" method of specifying d'tors is deprecated on Darwin. And it can lead to some ambiguities when dealing with multiple libraries. <rdar://problem/11110106> llvm-svn: 157852
* Implement the indirect counter increment code in a better way. Instead ofBill Wendling2012-05-281-53/+72
| | | | | | | | replicating the code for every place it's needed, we instead generate a function that does that for us. This function is local to the executable, so there shouldn't be any writing violations. llvm-svn: 157564
* The llvm_gcda_increment_indirect_counter function writes to the arguments thatBill Wendling2012-05-251-17/+57
| | | | | | | | | | | | | | are passed in. However, those arguments may be in a write-protected area, as far as the runtime library is concerned. For instance, the data could be placed into a 'linkedit' section, which isn't writable. Emit the code from llvm_gcda_increment_indirect_counter directly into the function instead. Note: The code for this is ugly, and can lead to bloat. We should look into simplifying this code instead of having all of these branches. <rdar://problem/11181370> llvm-svn: 157505

| | | | | | | | | | | | | | 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. llvm-svn: 130186
