2010-04-05IRgen: Lift BitFieldInfo to CGBitFieldInfo at namespace level.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100433 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-31IRGen: Move the auxiliary data structures tracking AST -> LLVM mappings out ↵Daniel Dunbar
of CodeGenTypes, to per-record CGRecordLayout structures. - I did a cursory check that this was perf neutral, FWIW. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99978 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-31CGRecordLayoutBuilder: Switch unions to use same mechanism for tracking ↵Daniel Dunbar
field and bit-field info as structs. - Anders, please check. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99977 91177308-0d34-0410-b5e6-96231b3b80d8

2009-12-16Baby steps towards fixing PR5589. If a class needs a vtable pointer, add one.Anders Carlsson
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@91545 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-08No need to add tail padding if the resulting LLVM struct type will have the ↵Anders Carlsson
same size as the final record size. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90820 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-03If the alignment of the chosen field in a union is greater than the ↵Anders Carlsson
alignment of the union, we need to use a packed LLVM struct. Fixes <rdar://problem/7184250>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@80964 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-02Packed unions should be packed. Fixes an assert Daniel reported.Anders Carlsson
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@80808 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-23More work towards zero-initializing structs that contain member pointers in ↵Anders Carlsson
constant expressions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@79805 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-23Remove the PaddingFields member from CGRecordLayout, it wasn't used anyway.Anders Carlsson
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@79799 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-13Update for LLVM API change.Owen Anderson
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@78946 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-08Take #pragma pack into account when laying out structs. Fixes ↵Anders Carlsson
rdar://problem/7095436. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@78490 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-08Introduce a new PragmaPack attribute, and use it for #pragma pack. The ↵Anders Carlsson
PackedAttr now only represents __attribute__((packed)). This is necessary because #pragma pack and __attribute__((packed)) have different semantics. No functionality change yet, but this lays the groundwork for fixing a record layout bug. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@78483 91177308-0d34-0410-b5e6-96231b3b80d8

table as it has its own place now. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@77491 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-27Some minor changes toward support of dataFariborz Jahanian
member access in the presense of non-virtual bases. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@77246 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-27Enable the new struct type builder now that the constant struct builder ↵Anders Carlsson
works. (The old code will still be there until we know that everything works well. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@77190 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-27Fix a tail padding bug in the record layout builder code. The bug was found ↵Anders Carlsson
by an existing test. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@77189 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76969 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-24Get rid of the size parameter to AppendField. No functionality change.Anders Carlsson
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76931 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-23Don't just store the field/bit field info one field, do it for all fields in ↵Anders Carlsson
the union. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76907 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-23Correct a thinko in bitfield layout code. Fixes PR4611.Anders Carlsson
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76898 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-23We don't need to keep track of the packed alignment, just whether the struct ↵Anders Carlsson
is packed or not. Fixes PR4610. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76884 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-23Move the LLVM field number for bit fields into the BitFieldInfo structure, ↵Anders Carlsson
since it's meaning is completely different than for non-bit fields. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76882 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76847 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-23Check in CGRecordLayoutBuilder which is a reimplementation of the record ↵Anders Carlsson
layout code. (Yay, no more packed structs unless absolutely necessary). We currently don't use the layouts being built but that will change when the new code is mature enough :) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76845 91177308-0d34-0410-b5e6-96231b3b80d8
