Tools and libraries will be built into $(BUILD_OBJ_ROOT)/$(BuildMode)/bin and \ $(BUILD_OBJ_ROOT)/$(BuildMode)/lib, respectively. Furthermore, the example \ programs will go in $(BUILD_OBJ_ROOT)/$(BuildMode)/examples to keep them \ separate from the tools and hopefully out of the PATH. Install targets \ have not changed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17953 91177308-0d34-0410-b5e6-96231b3b80d8

2004-11-18Update current expected failures list - expand it to include all ofBrian Gaeke
SingleSource. Update to-do list (open-coding refers to binary operations on longs, not to passing them into functions, which we already support.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17948 91177308-0d34-0410-b5e6-96231b3b80d8
2004-11-18Eliminate another common source of moves that the register allocatorNate Begeman
shouldn't be forced to coalesce for us: folded GEP operations. This too fires thousands of times across the testsuite. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17947 91177308-0d34-0410-b5e6-96231b3b80d8
2004-11-18When accessing the base register for global variables, use the registerNate Begeman
directly rather than making a copy for the register allocator to coalesce. This kills thousands of live intervals across the testsuite. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17946 91177308-0d34-0410-b5e6-96231b3b80d8
2004-11-18* There is no reason for SpillWeights to be an instance varChris Lattner
* Do not put fixed registers into the unhandled set. This means they will never find their way into the inactive, active, or handled sets, so we can simplify a bunch of code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17945 91177308-0d34-0410-b5e6-96231b3b80d8

2004-11-18Moderate head scratching reveals that this conditional is not needed. IfChris Lattner
i->start == j->start, then certainly i->end > j->start. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17943 91177308-0d34-0410-b5e6-96231b3b80d8
2004-11-18Clean up and fix cast codegen by removing cases that are handled elsewhere,Nate Begeman
and properly emitting signed short to unsigned int. This fixes the last regression vs. the CBE, MultiSource/Applications/hbd. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17942 91177308-0d34-0410-b5e6-96231b3b80d8

2004-11-18Add a counter for the number of times linscan has to backtrack. Start usingChris Lattner
the iterator hints we have to speed up overlaps(). This speeds linscan up by about .2s (out of 8.7) on 175.vpr for PPC. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17935 91177308-0d34-0410-b5e6-96231b3b80d8

2004-11-18* Improve comments/documentation substantiallyChris Lattner
* Eliminate the releaseMemory method, this is not an analysis * Change the fixed, active, and inactive lists of intervals to maintain an iterator for the current position in the interval. This allows us to do constant time increments of the iterator instead of having to do a binary search to find our liverange in our liveinterval all of the time, which substantially speeds up cases where LiveIntervals have many LiveRanges - which is very common for physical registers. On targets with many physregs, this can make a noticable difference. With a release build of LLC for PPC, this halves the time in processInactiveIntervals and processActiveIntervals, from 1.5s to .75s. This also lays the ground for more to come. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17933 91177308-0d34-0410-b5e6-96231b3b80d8
