2005-08-26Change ConstantPoolSDNode to actually hold the Constant itself instead ofChris Lattner
putting it into the constant pool. This allows the isel machinery to create constants that it will end up deciding are not needed, without them ending up in the resultant function constant pool. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23081 91177308-0d34-0410-b5e6-96231b3b80d8
2005-08-26Fix a huge annoyance: SelectNodeTo took types before the opcode unlikeChris Lattner
every other SD API. Fix it to take the opcode before the types. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23079 91177308-0d34-0410-b5e6-96231b3b80d8

2005-08-24For PR616:Reid Spencer
These patches make threading optional in LLVM. The configuration scripts are now modified to accept a --disable-threads switch. If this is used, the Mutex class will be implemented with all functions as no-op. Furthermore, linking against libpthread will not be done. Finally, the ParallelJIT example needs libpthread so its makefile was changed to always add -lpthread to the link line. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23003 91177308-0d34-0410-b5e6-96231b3b80d8
2005-08-24Keep the killed/dead sets sorted, so that "KillsRegister" can do a quickChris Lattner
binary search to test for membership. This speeds up LLC a bit more on KC++, e.g. on itanium from 16.6974s to 14.8272s, PPC from 11.4926s to 10.7089s and X86 from 10.8128s to 9.7943s, with no difference in generated code (like all of the RA patches). With these changes, isel is the slowest pass for PPC/X86, but linscan+live intervals is still > 50% of the compile time for itanium. More work could be done, but this is the last for now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22993 91177308-0d34-0410-b5e6-96231b3b80d8
2005-08-23Change live variables from using multimaps to using maps of vectors andChris Lattner
rearrange some of the accessors to be more efficient. This makes it much more efficient to iterate over all of the things with the same value. This speeds up liveintervals analysis from 8.63s to 3.79s with a release build of llc on kc++ with -march=ia64. This also speeds up live var from 1.66s -> 0.87s as well, reducing total llc time from 20.1s->15.2s. This also speeds up other targets slightly, e.g. llc time on X86 from 16.84 -> 16.45s, and PPC from 17.64->17.03s. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22990 91177308-0d34-0410-b5e6-96231b3b80d8

2005-08-16Eliminate the RegSDNode class, which 3 nodes (CopyFromReg/CopyToReg/ImplicitDef)Chris Lattner
used to tack a register number onto the node. Instead of doing this, make a new node, RegisterSDNode, which is a leaf containing a register number. These three operations just become normal DAG nodes now, instead of requiring special handling. Note that with this change, it is no longer correct to make illegal CopyFromReg/CopyToReg nodes. The legalizer will not touch them, and this is bad, so don't do it. :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22806 91177308-0d34-0410-b5e6-96231b3b80d8
