f141dd1b95 Remove the old vtable layout code.

a086edc0e6 Remove UseNewVTableCode checks. 
llvm-svn: 99868
 2010-03-30 03:35:35 +00:00

a627ac7ee6 More vtable work - it's not possible to use the new vtable code for everything by setting a flag inside CGVtable.cpp. My plan is to run some tests and bootstrap and once that's done flip the bit. 
llvm-svn: 99804

f6f24c609b Cleanup, no functionality change.

a4147148ff When -fdump-vtable-layouts is specified, construction vtable initializers will be generated using the new vtable layout code. (The code is still not completely in place but this is a huge step forward).

d03325c54f More address point map shuffling.

0534b0201e Shuffle some code around; this will make it easier to use the new layout code for address points. 
llvm-svn: 99461

e90954de64 More vtable improvements. We now compute and keep track of all vtable related information which avoids computing the same vtable layout over and over.

67fbf9853f Use getNamedGlobal instead of getGlobalVariable. (Fixes self-host).

5f9a881e1e Store the address points for constructor vtables directly in the VTT builder, because that's the only time they're needed.

8174f2c23c Work-in-progess rewrite of thunks: move thunk generation outside of vtable 
generation, and make sure we generate thunks when the function is defined
rather than when the vtable is defined.

fb4dda4fed Instead of storing CXXMethodDecls in the vtable builder, store GlobalDecls so we can represent both the complete and deleting destructors. Also, when encountering a destructor decl, emit entries for both the complete and deleting destructors. Mike, please review. 
With this change, FileCheck builds and runs the clang test suite without failures!
