2004-07-19Added support for stdint.h. It is now automatically included byJohn Criswell
DataTypes.h. So far, it doesn't seem to break Linux, Solaris, or MacOS X. This should automatically include it for those people who need it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@15006 91177308-0d34-0410-b5e6-96231b3b80d8

2004-07-19When joining intervals, join intervals in deeply nested loops first. ThisChris Lattner
is a simple change, but seems to improve code a little. For example, on 256.bzip2, we went from 75.0s -> 73.33s (2% speedup). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@15004 91177308-0d34-0410-b5e6-96231b3b80d8

Patch contributed by the fabulous Nate Begeman. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14994 91177308-0d34-0410-b5e6-96231b3b80d8
2004-07-19Two changes, both very significant:Chris Lattner
* vreg <-> vreg joining now works, enable it unconditionally when joining is enabled (which is the default). * Fix a serious pessimization of spill code where we were saying that a spilled DEF operand was live into the subsequent instruction. This allows for substantially better code when spilling starts to happen. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14993 91177308-0d34-0410-b5e6-96231b3b80d8
2004-07-19See comments. The live intervals were not coming out of the spiller in sortedChris Lattner
order, causing the inactive list in the linearscan list to get unsorted, which basically fuxored everything up severely. These seems to fix the joiner, so with more testing I will enable it by default. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14992 91177308-0d34-0410-b5e6-96231b3b80d8

2004-07-19Add some asserts that the list of intervals returned by addIntervalsForSpillsChris Lattner
is sorted. This is not the case currently, which is causing no end of problems. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14990 91177308-0d34-0410-b5e6-96231b3b80d8
2004-07-19remove the mbbi2mbbMap_, which was just keeping track of mbb order anyway.Chris Lattner
Heavily refactor handleVirtualRegisterDef, adding comments and making it more efficient. It is also much easier to follow and convince ones self that it is correct :) Add -debug output to the joine, showing the result of joining the intervals. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14989 91177308-0d34-0410-b5e6-96231b3b80d8
