* Use a more appropriate LLVM type for the vtable pointer.Anders Carlsson2010-05-051-3/+5
| | | | llvm-svn: 103078
* IRgen: Fix another case where we generated an invalid access component when weDaniel Dunbar2010-04-221-13/+12
| | | | | | | immediately narrowed the access size. Fix this (and previous case) by just choosing a better access size up-front. llvm-svn: 102068
* IRgen: Fix case where we might generate an access component with width == 0, ifDaniel Dunbar2010-04-221-0/+10
| | | | | | | we have to narrow the access side immediately (can happen with packed, -fno-bitfield-type-align). llvm-svn: 102067

| | | | | | | | | | | | of the structure, which we also now verify as part of the post-layout consistency checks. - This fixes some pedantic bugs with packed structures, as well as major problems with -fno-bitfield-type-align. - Fixes PR5591, PR5567, and all known -fno-bitfield-type-align issues. - Review appreciated. llvm-svn: 102045

* Simplify wide bit-field layout in CGRecordLayoutBuilder, and also fix a bug ↵Anders Carlsson2010-04-171-15/+10

| | | | | | | | arguments, it is now an immutable object. Also, add some checking of various invariants that should hold on the CGBitFieldInfo access. llvm-svn: 101345
* IRgen: Eliminate now unused fields from CGBitFieldInfo.Daniel Dunbar2010-04-151-7/+4
| | | | llvm-svn: 101344
* IRgen: Enhance CGBitFieldInfo with enough information to fully describe the ↵Daniel Dunbar2010-04-131-5/+65
| | | | | | | | | | "policy" with which a bit-field should be accessed. - For now, these policies are computed to match the current IRgen strategy, although the new information isn't being used yet (except in -fdump-record-layouts). - Design comments appreciated. llvm-svn: 101178
