* raw_ostream: while it is generally desirable to do larger writes, it can lead toBenjamin Kramer2011-03-041-3/+7
| | | | | | | | | | inefficient file system buffering if the writes are not a multiple of the desired buffer size. Avoid this by limiting the large write to a multiple of the buffer size and copying the remainder into the buffer. Thanks to Dan for pointing this out. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127026 91177308-0d34-0410-b5e6-96231b3b80d8
* Renumber slot indexes locally when possible.Jakob Stoklund Olesen2011-03-042-23/+36
| | | | | | | | | | | | | Initially, slot indexes are quad-spaced. There is room for inserting up to 3 new instructions between the original instructions. When we run out of indexes between two instructions, renumber locally using double-spaced indexes. The original quad-spacing means that we catch up quickly, and we only have to renumber a handful of instructions to get a monotonic sequence. This is much faster than renumbering the whole function as we did before. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127023 91177308-0d34-0410-b5e6-96231b3b80d8

Also remove an extra empty index that was inserted after each basic block.

* Revert commit 126684 "Use the correct shift amount type". It is only the ↵Duncan Sands2011-03-041-1/+1
| | | | | | | | | | | | correct type after type legalization has completed. Before then it may simply not be big enough to hold the shift amount, particularly on x86 which uses a very small type for shifts (this issue broke stuff in the past which is why LegalizeTypes carefully uses a large type for shift amounts). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127000 91177308-0d34-0410-b5e6-96231b3b80d8
