2012-07-12Add the ObjFW runtime. Patch by Jonathan Schleifer!John McCall
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160102 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-03Rename the GCC Objective-C runtime to gcc from gnu-fragile and the GNUstepDavid Chisnall
runtime to gnustep from gnu. Fix EH for the GCC runtime. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@159684 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-20Restructure how the driver communicates information about theJohn McCall
target Objective-C runtime down to the frontend: break this down into a single target runtime kind and version, and compute all the relevant information from that. This makes it relatively painless to add support for new runtimes to the compiler. Make the new -cc1 flag, -fobjc-runtime=blah-x.y.z, available at the driver level as a better and more general alternative to -fgnu-runtime and -fnext-runtime. This new concept of an Objective-C runtime also encompasses what we were previously separating out as the "Objective-C ABI", so fragile vs. non-fragile runtimes are now really modelled as different kinds of runtime, paving the way for better overall differentiation. As a sort of special case, continue to accept the -cc1 flag -fobjc-runtime-has-weak, as a sop to PLCompatibilityWeak. I won't go so far as to say "no functionality change", even ignoring the new driver flag, but subtle changes in driver semantics are almost certainly not intended. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158793 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-15It turns out that implementing the rethrow-on-fallthroughJohn McCall
semantics of a ctor/dtor function-try-block catch handler by pushing a normal cleanup is not just overkill but actually actively wrong when the handler contains an explicit return (which is only legal in a dtor). Just emit the rethrow as ordinary code at the fallthrough point. Fixes PR13102. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158488 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-28When we can't prove that the target of an aggregate copy isJohn McCall
a complete object, the memcpy needs to use the data size of the structure instead of its sizeof() value. Fixes PR12204. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@153613 91177308-0d34-0410-b5e6-96231b3b80d8

2011-11-10Whenever explicitly activating or deactivating a cleanup, weJohn McCall
need to provide a 'dominating IP' which is guaranteed to dominate the (de)activation point but which cannot be avoided along any execution path from the (de)activation point to the push-point of the cleanup. Using the entry block is bad mojo. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@144276 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-22Don't remove filters.Bill Wendling
It's not valid to remove filters from landingpad instructions, even if we catch the type. The metadata won't be set up correctly. Testcase is projects/llvm-test/SingleSource/UnitTests/EH/filter-2.cpp. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140335 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-19The eh.selector intrinsic isn't used anymore. Replace the check here with aBill Wendling
check for the landingpad instruction instead. This check looks at each of the clauses in the landingpad instruction. If it's a catch clause, it compares the name directly with the global. If it's a filter clause, it has to look through each value in the filer to see if any have the prefix. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140075 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-19Throw the switch to convert clang to the new exception handling model!Bill Wendling
This model uses the 'landingpad' instruction, which is pinned to the top of the landing pad. (A landing pad is defined as the destination of the unwind branch of an invoke instruction.) All of the information needed to generate the correct exception handling metadata during code generation is encoded into the landingpad instruction. The new 'resume' instruction takes the place of the llvm.eh.resume intrinsic call. It's lowered in much the same way as the intrinsic is. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140049 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-02Extend the ASTContext constructor to delay the initialization ofDouglas Gregor
builtin types (When requested). This is another step toward making ASTUnit build the ASTContext as needed when loading an AST file, rather than doing so after the fact.

2011-08-11Simplify EH control flow by observing that EH scopes form a simpleJohn McCall
hierarchy of delegation, and that EH selector values are meaningful function-wide (good thing, too, or inlining wouldn't work). 2,3d 1a hierarchy of delegation and that EH selector values have the same meaning everywhere in the function instead of being meaningful only in the context of a specific selector. This removes the need for routing edges through EH cleanups, since a cleanup simply always branches to its enclosing scope. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137293 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-22Emit @finally blocks completely lazily instead of forcing theirJohn McCall
existence by always threading an edge from the catchall. Not doing this was previously causing a crash in the very extreme case where neither the normal cleanup nor the EH catchall was actually reachable: we would delete the catchall entry block, which would cause us to delete the entry block of the finally cleanup as well because the cleanup logic would merge the blocks, which in turn triggered an assert because later blocks in the finally would still be using values from the entry. Laziness turns out to be the most elegant solution to the problem. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@133601 91177308-0d34-0410-b5e6-96231b3b80d8
