that there is no padding. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43691 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-05Eliminate the remaining uses of getTypeSize. ThisDuncan Sands
should only effect x86 when using long double. Now 12/16 bytes are output for long double globals (the exact amount depends on the alignment). This brings globals in line with the rest of LLVM: the space reserved for an object is now always the ABI size. One tricky point is that only 10 bytes should be output for long double if it is a field in a packed struct, which is the reason for the additional argument to EmitGlobalConstant. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43688 91177308-0d34-0410-b5e6-96231b3b80d8

2007-11-04Change uses of getTypeSize to getABITypeSize, getTypeStoreSizeDuncan Sands
or getTypeSizeInBits as appropriate in ScalarReplAggregates. The right change to make was not always obvious, so it would be good to have an sroa guru review this. While there I noticed some bugs, and fixed them: (1) arrays of x86 long double have holes due to alignment padding, but this wasn't being spotted by HasStructPadding (renamed to HasPadding). The same goes for arrays of oddly sized ints. Vectors also suffer from this, in fact the problem for vectors is much worse because basic vector assumptions seem to be broken by vectors of type with alignment padding. I didn't try to fix any of these vector problems. (2) The code for extracting smaller integers from larger ones (in the "int union" case) was wrong on big-endian machines for integers with size not a multiple of 8, like i1. Probably this is impossible to hit via llvm-gcc, but I fixed it anyway while there and added a testcase. I also got rid of some trailing whitespace and changed a function name which had an obvious typo in it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43672 91177308-0d34-0410-b5e6-96231b3b80d8
