* Fix some scavenger performance issues.Jakob Stoklund Olesen2012-01-292-24/+13
| | | | | | | | | | | | | - Don't call malloc+free in the very hot forward(). - Don't call isTiedToDefOperand(). - Don't create BitVector temporaries. - Merge DeadRegs into KillRegs. - Eliminate the early clobber checks, they were irrelevant to scavenging. - Remove unnecessary code from -Asserts builds. This speeds up ARM PEI by 3.4x and overall llc -O0 codegen time by 11%. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@149189 91177308-0d34-0410-b5e6-96231b3b80d8

* Don't always create a separate block for the call to _Unwind_Resume.Bill Wendling2012-01-281-32/+61
| | | | | | | | | | | | Sometimes there is only one 'resume' instruction per function. In those situations, we don't need a separate block for the call to _Unwind_Resume. In fact, it adds a lot of overhead to code-gen if we do that -- especially at -O0. If we have a single 'resume' instruction, just generate the call within that block. <rdar://problem/10694814> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@149159 91177308-0d34-0410-b5e6-96231b3b80d8

* Remove Deprecated FeaturesDavid Greene2012-01-271-250/+51
| | | | | | | | | | | | Move to a model where we build whatever branches are checked out in the source directories. This was a bit too smart (and complicated) in handling details best left to the user and the revision control system. In addition, get rid of support for llvm-gcc and building gcc as these are no longer necessary. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@149149 91177308-0d34-0410-b5e6-96231b3b80d8

* Place the GEP instructions nearer to the instructions which use them.Bill Wendling2012-01-271-37/+36
| | | | | | | | | | | | GEP instructions are there for the compiler and shouldn't really output much code (if any at all). When a GEP is stored in the entry block, Fast ISel (for one) will not know that it could fold it into further uses. For instance, inside of the EH handling code. This results in a lot of unnecessary spills and loads which bloat code and slows down pretty much everything. <rdar://problem/10694814> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@149114 91177308-0d34-0410-b5e6-96231b3b80d8
