* Revamp the "ConstantStruct::get" methods. Previously, these were scatteredChris Lattner2011-06-201-39/+39
| | | | | | | | | | | | | | | all over the place in different styles and variants. Standardize on two preferred entrypoints: one that takes a StructType and ArrayRef, and one that takes StructType and varargs. In cases where there isn't a struct type convenient, we now add a ConstantStruct::getAnon method (whose name will make more sense after a few more patches land). It would be "really really nice" if the ConstantStruct::get and ConstantVector::get methods didn't make temporary std::vectors. llvm-svn: 133412

| | | | | | | | | | | | mean that it has to be ConstantArray of ConstantStruct. We might have ConstantAggregateZero, at either level, so don't crash on that. Also, semi-deprecate the sentinal value. The linker isn't aware of sentinals so we end up with the two lists appended, each with their "sentinals" on them. Different parts of LLVM treated sentinals differently, so make them all just ignore the single entry and continue on with the rest of the list. llvm-svn: 129307

* Get rid of static constructors for pass registration. Instead, every pass ↵Owen Anderson2010-10-191-1/+3
| | | | | | | | | | | | | | | | | exposes an initializeMyPassFunction(), which must be called in the pass's constructor. This function uses static dependency declarations to recursively initialize the pass's dependencies. Clients that only create passes through the createFooPass() APIs will require no changes. Clients that want to use the CommandLine options for passes will need to manually call the appropriate initialization functions in PassInitialization.h before parsing commandline arguments. I have tested this with all standard configurations of clang and llvm-gcc on Darwin. It is possible that there are problems with the static dependencies that will only be visible with non-standard options. If you encounter any crash in pass registration/creation, please send the testcase to me directly. llvm-svn: 116820
