2010-04-16fix a bogus assertion exposed by a recent change: packing theChris Lattner
struct may cause it to shrink more than one byte. Before my recent changes we compiled the new test into: %0 = type { [6 x i8] } @x = global %0 { [6 x i8] undef }, align 2 ; <%0*> [#uses=0] which is obviously bogus. Now we compile it into: %0 = type <{ i32, i8, i8 }> @x = global %0 zeroinitializer, align 2 ; <%0*> [#uses=0] Where the last byte only is tail padding. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101536 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-15IRgen: Eliminate now unused fields from CGBitFieldInfo.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101344 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-15IRgen: (Reapply 101222, with fixes) Move EmitStoreThroughBitfieldLValue to ↵Daniel Dunbar
use new CGBitfieldInfo::AccessInfo decomposition, instead of computing the access policy itself. - Sadly, this doesn't seem to give any .ll size win so far. It is possible to make this routine significantly smarter & avoid various shifting, masking, and zext/sext, but I'm not really convinced it is worth it. It is tricky, and this is really instcombine's job. - No intended functionality change; the test case is just to increase coverage & serves as a demo file, it worked before this commit. The new fixes from r101222 are: 1. The shift to the target position needs to occur after the value is extended to the correct size. This broke Clang bootstrap, among other things no doubt. 2. Swap the order of arguments to OR, to get a tad more constant folding. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101339 91177308-0d34-0410-b5e6-96231b3b80d8

Stop multiplying constant by 8 accordingly in the header and change intrinsic definition for what types we expect. Add to existing palignr test to check that we're emitting the correct things. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101332 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-13IRgen: Move EmitLoadOfBitfieldLValue to use new CGBitfieldInfo::AccessInfo ↵Daniel Dunbar
decomposition, instead of computing the access policy itself. - This lets the method focus slightly more on emitting clean IR to honor the policy which has been selected. On 403.gcc's combine.c, x86_64, -O0, this reduces the number of lines in the .ll file (~= # of instructions) by 2.5%. - No intended functionality change -- at -O3 this should produce equivalent if not identical output. On 403.gcc's combine.c, x86_64, -O3, this isn't quite true and some of the changes are regressions, but I'm not going to worry about that until we move to a new access policy. - There is still some room for improvement in the generated IR, in particular we can usually fold the sign-extension of the bit-field into one of the component access. See the FIXME. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101192 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

2010-04-13Rework the ConstStructBuilder code to emit missing initializerChris Lattner
elements with explicit zero values instead of with tail padding. On an example like this: struct foo { int a; int b; }; struct foo fooarray[] = { {1, 2}, {4}, }; We now lay this out as: @fooarray = global [2 x %struct.foo] [%struct.foo { i32 1, i32 2 }, %struct.foo { i32 4, i32 0 }] instead of as: @fooarray = global %0 <{ %struct.foo { i32 1, i32 2 }, %1 { i32 4, [4 x i8] zeroinitializer } }> Preserving both the struct type of the second element, but also the array type of the entire thing. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101155 91177308-0d34-0410-b5e6-96231b3b80d8
