2005-08-25LFS/STFS load and store FP values, not integer ones. This change allows usChris Lattner
to codegen this: float foo() { return 1.245; } into this: _foo: lis r2, ha16(.CPI_foo_0) lfs f1, lo16(.CPI_foo_0)(r2) blr instead of this: _foo: lis r2, ha16(.CPI_foo_0) lfs r2, lo16(.CPI_foo_0)(r2) <-- ouch or f1, r2, r2 <-- ouch blr with the dag isel. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23033 91177308-0d34-0410-b5e6-96231b3b80d8

2005-08-24teach selection dag mask tracking about the fact that select_cc operates likeChris Lattner
select. Also teach it that the bit count instructions can only set the low bits of the result, depending on the size of the input. This allows us to compile this: int %eq0(int %a) { %tmp.1 = seteq int %a, 0 ; <bool> [#uses=1] %tmp.2 = cast bool %tmp.1 to int ; <int> [#uses=1] ret int %tmp.2 } To this: _eq0: cntlzw r2, r3 srwi r3, r2, 5 blr instead of this: _eq0: cntlzw r2, r3 rlwinm r3, r2, 27, 31, 31 blr when setcc is marked illegal on ppc (which restores parity to non-illegal setcc). Thanks to Nate for pointing this out. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23013 91177308-0d34-0410-b5e6-96231b3b80d8

2005-08-24For PR619:Reid Spencer
Make any header files that are automatically generated be preconditions of the compilation. This ensures that if a *.h.in file is changed then its corresponding *.h file gets updated on the next rebuild. Note that this can lead to confusing (but correct) results if the *.h.in file changed unsubstantially so that autoheader doesn't update the *.h file. In that case, manually touch the *.h file in question to restore order. Moral of the story, if you're going to "touch" a *.in file then modify it substantially. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23006 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

2005-08-23Keep track of which registers are related to which other registers.Chris Lattner
Use this information to avoid doing expensive interval intersections for registers that could not possible be interesting. This speeds up linscan on ia64 compiling kc++ in release mode from taking 7.82s to 4.8s(!), total itanium llc time on this program is 27.3s now. This marginally speeds up PPC and X86, but they appear to be limited by other parts of linscan, not this code. On this program, on itanium, live intervals now takes 41% of llc time. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22986 91177308-0d34-0410-b5e6-96231b3b80d8
