| | | | llvm-svn: 81346
* If the alignment of the chosen field in a union is greater than the ↵Anders Carlsson2009-09-031-1/+8
| | | | | | alignment of the union, we need to use a packed LLVM struct. Fixes <rdar://problem/7184250>. llvm-svn: 80964
* Packed unions should be packed. Fixes an assert Daniel reported.Anders Carlsson2009-09-021-2/+1

| | | | | | rdar://problem/7095436. llvm-svn: 78490
* Introduce a new PragmaPack attribute, and use it for #pragma pack. The ↵Anders Carlsson2009-08-081-11/+3
| | | | | | | | 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. llvm-svn: 78483

* Enable the new struct type builder now that the constant struct builder ↵Anders Carlsson2009-07-271-3/+0
| | | | | | works. (The old code will still be there until we know that everything works well. llvm-svn: 77190
* Fix a tail padding bug in the record layout builder code. The bug was found ↵Anders Carlsson2009-07-271-6/+15
| | | | | | by an existing test. llvm-svn: 77189
* Check in a half finished new constant struct builder (Obviously not used yet).Anders Carlsson2009-07-241-2/+2

* Get rid of the size parameter to AppendField. No functionality change.Anders Carlsson2009-07-241-7/+6
| | | | llvm-svn: 76931
* Don't just store the field/bit field info one field, do it for all fields in ↵Anders Carlsson2009-07-231-12/+6

* Fix another thinko.Anders Carlsson2009-07-231-2/+2

* We don't need to keep track of the packed alignment, just whether the struct ↵Anders Carlsson2009-07-231-15/+10
| | | | | | is packed or not. Fixes PR4610. llvm-svn: 76884
* Move the LLVM field number for bit fields into the BitFieldInfo structure, ↵Anders Carlsson2009-07-231-6/+6
| | | | | | since it's meaning is completely different than for non-bit fields. llvm-svn: 76882
* Set field info for unions.Anders Carlsson2009-07-231-1/+11
| | | | llvm-svn: 76856
* Handle zero width bit fields in unions correctly (by ignoring them).Anders Carlsson2009-07-231-0/+9

* Implement union layout support.Anders Carlsson2009-07-231-5/+45
| | | | llvm-svn: 76846
* Check in CGRecordLayoutBuilder which is a reimplementation of the record ↵Anders Carlsson2009-07-231-0/+272
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 :) llvm-svn: 76845
