* This file was schizophrenic when it came to representing sizes. In someChris Lattner2005-01-291-44/+45
| | | | | | | | | | | cases it represented them as 'unsigned's, which are not enough for 64-bit hosts. In other cases, it represented them as uint64_t's, which are inefficient for 32-bit hosts. This patch unifies all of the sizes to use size_t instead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@19918 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | bzip2: block size 9 -> 5, reduces memory by 400Kbytes, doesn't affect speed or compression ratio on all but the largest bytecode files (>1MB) zip: level 9 -> 6, this speeds up compression time by ~30% but only degrades the compressed size by a few bytes per megabyte. Those few bytes aren't worth the effort. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17647 91177308-0d34-0410-b5e6-96231b3b80d8
