2011-03-04Go back to comparing spill weights when deciding if interference can be evicted.Jakob Stoklund Olesen
It gives better results. Sometimes, a live range can be large and still have high spill weight. Such a range should not be spilled. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127036 91177308-0d34-0410-b5e6-96231b3b80d8

2011-03-04When decling to reuse existing expressions that involve casts, ignoreDan Gohman
bitcasts, which are really no-ops here. This fixes slowdowns on MultiSource/Applications/aha and others. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127031 91177308-0d34-0410-b5e6-96231b3b80d8

2011-03-04Be nice to Xcore and the XMOS assembler and avoid quoting section namesJoerg Sonnenberger
that contain only letters, digits and the characters "_" and ".". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127028 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-04Lowers block address. Currently asserts when relocation model is not PIC. ↵Bruno Cardoso Lopes
Patch by Akira Hatanaka git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127027 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-04raw_ostream: while it is generally desirable to do larger writes, it can lead toBenjamin Kramer
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
2011-03-04Renumber slot indexes locally when possible.Jakob Stoklund Olesen
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

individual variable's info from merged global. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127019 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-04Expands FCOS and FSIN nodes when type is f64.Bruno Cardoso Lopes
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127017 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-04Number SlotIndexes uniformly without looking at the number of defs on each ↵Jakob Stoklund Olesen
instruction. You can't really predict how many indexes will be needed from the number of defs, so let's keep it simple. Also remove an extra empty index that was inserted after each basic block. It was intended for live-out ranges, but it was never used that way. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127014 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-04raw_ostream: If writing a string that is larger than the buffer, write it ↵Benjamin Kramer
directly instead of doing many buffer-sized writes. This caps the number of write(2) calls per string to a maximum of 2. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127010 91177308-0d34-0410-b5e6-96231b3b80d8

2011-03-04Remove (hopefully) all trailing whitespaces from the mips backend. Patch by ↵Bruno Cardoso Lopes
Hatanaka, Akira git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127003 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-04Revert commit 126684 "Use the correct shift amount type". It is only the ↵Duncan Sands
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
2011-03-04Allow vector shifts (shl,lshr,ashr) on SPU.Kalle Raiskila
There was a previous implementation with patterns that would have matched e.g. shl <v4i32> <i32>, but this is not valid LLVM IR so they never were selected. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126998 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-04Allow load from constant on SPU.Kalle Raiskila
A 'load <4 x i32>* null' crashes llc before this fix. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126995 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-04Fold "icmp pred (srem X, Y), Y" like we do for urem. Handle signed comparisonsNick Lewycky
in the urem case, though not the other way around. This is enough to get #3 from PR9343! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126991 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-04Teach instruction simplify to use constant ranges to solve problems of the formNick Lewycky
"icmp pred %X, CI" and a number of examples where "%X = binop %Y, CI2". Some of these cases (div and rem) used to make it through opt -O2, but the others are probably now making code elsewhere redundant (probably instcombine). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126988 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-04DenseMap<uintptr_t,...> doesn't allow all values as keys.Jakob Stoklund Olesen
Avoid colliding with the sentinels, hopefully unbreaking llvm-gcc-x86_64-linux-selfhost. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126982 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-04Minor pre-RA-sched fixes and cleanup.Andrew Trick
Fix the PendingQueue, then disable it because it's not required for the current schedulers' heuristics. Fix the logic for the unused list-ilp scheduler. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126981 91177308-0d34-0410-b5e6-96231b3b80d8

2011-03-04Use an IndexedMap instead of a DenseMap for the live-out cache.Jakob Stoklund Olesen
This speeds up updateSSA() so it only accounts for 5% of the live range splitting time. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126972 91177308-0d34-0410-b5e6-96231b3b80d8

2011-03-03There are times when the landing pad won't have a call to 'eh.selector' inBill Wendling
it. It's been assumed up til now that it would be in its immediate successor. However, this isn't necessarily the case. It could be in one of its successor's successors. Modify the code to more thoroughly check for an 'eh.selector' call in successors. It only looks at a successor if we get there as a result of an unconditional branch. Testcase ObjC/exceptions-4.m in r126968. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126969 91177308-0d34-0410-b5e6-96231b3b80d8
