2010-11-09Introduce the concept of a non-virtual base type to CGRecordLayoutBuilder as ↵Anders Carlsson
a first step towards fixing PR6995. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@118491 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-31Rename getBaseClassOffset to getBaseClassOffsetInBits and introduce a ↵Anders Carlsson
getBaseClassOffset which returns the offset in CharUnits. Do the same thing for getVBaseClassOffset. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@117881 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-22Go back to asking CodeGenTypes whether a type is zero-initializable.John McCall
Make CGT defer to the ABI on all member pointer types. This requires giving CGT a handle to the ABI. It's way easier to make that work if we avoid lazily creating the ABI. Make it so. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111786 91177308-0d34-0410-b5e6-96231b3b80d8

2010-05-18Correctly initialize bases with member pointers. This should fix PR6441 but ↵Anders Carlsson
that test case is a bit weird and I'd like to investigate further before closing that bug. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@104025 91177308-0d34-0410-b5e6-96231b3b80d8

2010-05-18Start laying out bases as individual fields. We still use ugly i8 arrays but ↵Anders Carlsson
this is a step in the right direction. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@104012 91177308-0d34-0410-b5e6-96231b3b80d8

immediately narrowed the access size. Fix this (and previous case) by just choosing a better access size up-front. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@102068 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-22IRgen: Fix case where we might generate an access component with width == 0, ifDaniel Dunbar
we have to narrow the access side immediately (can happen with packed, -fno-bitfield-type-align). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@102067 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-22IRgen: Rewrite bit-field access policy to not access data beyond the bounds ↵Daniel Dunbar
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@102045 91177308-0d34-0410-b5e6-96231b3b80d8

non-bit-fields). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@102014 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-20IRgen: Always use i8 arrays to access union bit-fields. This is ugly, butDaniel Dunbar
matches how we currently handle structs, and this correctly handles -fno-bitfield-type-align. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101918 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-17Simplify wide bit-field layout in CGRecordLayoutBuilder, and also fix a bug ↵Anders Carlsson
where assigning to a bit-field member would overwrite other parts of the struct. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101681 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-13IRgen: Enhance CGBitFieldInfo with enough information to fully describe the ↵Daniel Dunbar
"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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101178 91177308-0d34-0410-b5e6-96231b3b80d8
