2010-04-22IRgen: Fix another case where we generated an invalid access component when weDaniel Dunbar
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
2010-04-22IRgen: Fix CGRecordLayout::print to print the bit-field infos in a ↵Daniel Dunbar
consistent order. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@102044 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-21IRgen: Add checking that the LLVM and AST record layout offsets agree (forDaniel Dunbar
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

-fdump-record-layouts. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101815 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-19IRgen: Kill unused function and move the type match assert to after record ↵Daniel Dunbar
dumping. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101814 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
2010-04-17Unnamed bit-fields in a union should be laid out with a type that doesn't ↵Anders Carlsson
affect alignment. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101673 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-17Factor union field layout code out into a separate function. No ↵Anders Carlsson
functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101671 91177308-0d34-0410-b5e6-96231b3b80d8

shortly (Daniel, please review). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101472 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-15IRgen: Change CGBitFieldInfo to take the AccessInfo as constructor ↵Daniel Dunbar
arguments, it is now an immutable object. Also, add some checking of various invariants that should hold on the CGBitFieldInfo access. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101345 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101344 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

2010-04-12IRgen: Add CGRecordLayout::dump, and dump (irgen) record layouts as part of ↵Daniel Dunbar
-fdump-record-layouts. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101051 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-08IRgen: Move the bit-field access type into CGBitFieldInfo, and change ↵Daniel Dunbar
bit-field LValues to just store the base address of object containing the bit-field. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100745 91177308-0d34-0410-b5e6-96231b3b80d8

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

2009-09-03If 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

2009-08-08Introduce 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
