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.

for cross-platform dynamic loading of shared objects.

visitCallInst works.  Support cast of byte/short/int to long.

llvm-svn: 17949

SingleSource. Update to-do list (open-coding refers to binary operations on
longs, not to passing them into functions, which we already support.)

shouldn't be forced to coalesce for us: folded GEP operations.  This too
fires thousands of times across the testsuite.

llvm-svn: 17947

directly rather than making a copy for the register allocator to coalesce.
This kills thousands of live intervals across the testsuite.

* 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.

incrementing i.

llvm-svn: 17944

i->start == j->start, then certainly i->end > j->start.

and properly emitting signed short to unsigned int.  This fixes the last
regression vs. the CBE, MultiSource/Applications/hbd.

search physreg intervals every time we access it.  This takes another

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.
