2012-09-13Use Nick's suggestion of storing a large NULL into the GV instead of memset, ↵Bill Wendling
which requires TargetData. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@163799 91177308-0d34-0410-b5e6-96231b3b80d8
2012-09-13Introduce the __llvm_gcov_flush function.Bill Wendling
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> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@163757 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-29Move llvm/Support/IRBuilder.h -> llvm/IRBuilder.hChandler Carruth
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159421 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-28Move lib/Analysis/DebugInfo.cpp to lib/VMCore/DebugInfo.cpp andBill Wendling
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159312 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-23Extend the IL for selecting TLS models (PR9788)Hans Wennborg
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159077 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-01Register the gcov "writeout" at init time. Don't list this as a d'tor. Instead,Bill Wendling
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> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157852 91177308-0d34-0410-b5e6-96231b3b80d8
2012-05-28Implement the indirect counter increment code in a better way. Instead ofBill Wendling
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157564 91177308-0d34-0410-b5e6-96231b3b80d8
2012-05-25The llvm_gcda_increment_indirect_counter function writes to the arguments thatBill Wendling
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> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157505 91177308-0d34-0410-b5e6-96231b3b80d8

2011-11-27Place the "cfg checksum" around a test. This was recently added in April 2011 toNick Lewycky
gcc, though I thought it was older (my gcc 4.4 has it as a local patch. Whoops!) This fixes PR10589. Also add some debugging statements. Remove GcnoFiles, the mapping from CompilationUnit to raw_ostream. Now that we start by iterating over each CU and descending into them, there's no need to maintain a mapping. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@145208 91177308-0d34-0410-b5e6-96231b3b80d8

Fix an off-by-one in string emission. Extra whoops! Tolerate DISubprograms that have null Function*'s attached to them.

2011-04-26Rename everything to follow LLVM style ... I think.Nick Lewycky
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
