* Change uses of getTypeSize to getABITypeSize, getTypeStoreSizeDuncan Sands2007-11-041-0/+30
| | | | | | | | | | | | | | | | | | | | | | | 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

* There are times when the coalescer would not coalesce away a copy but the copyEvan Cheng2007-11-031-0/+35
| | | | | | | | | | | | | | | | | can be eliminated by the allocator is the destination and source targets the same register. The most common case is when the source and destination registers are in different class. For example, on x86 mov32to32_ targets GR32_ which contains a subset of the registers in GR32. The allocator can do 2 things: 1. Set the preferred allocation for the destination of a copy to that of its source. 2. After allocation is done, change the allocation of a copy destination (if legal) so the copy can be eliminated. This eliminates 443 extra moves from 403.gcc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43662 91177308-0d34-0410-b5e6-96231b3b80d8
