* Tail call optimization improvements:Arnold Schwaighofer2008-04-301-0/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Move platform independent code (lowering of possibly overwritten arguments, check for tail call optimization eligibility) from target X86ISelectionLowering.cpp to TargetLowering.h and SelectionDAGISel.cpp. Initial PowerPC tail call implementation: Support ppc32 implemented and tested (passes my tests and test-suite llvm-test). Support ppc64 implemented and half tested (passes my tests). On ppc tail call optimization is performed if caller and callee are fastcc call is a tail call (in tail call position, call followed by ret) no variable argument lists or byval arguments option -tailcallopt is enabled Supported: * non pic tail calls on linux/darwin * module-local tail calls on linux(PIC/GOT)/darwin(PIC) * inter-module tail calls on darwin(PIC) If constraints are not met a normal call will be emitted. A test checking the argument lowering behaviour on x86-64 was added. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@50477 91177308-0d34-0410-b5e6-96231b3b80d8

* Use std::set instead of std::priority_queue for the RegReductionPriorityQueue. Roman Levenstein2008-04-291-1/+2
| | | | | | | | | | | | | | | | This removes the existing bottleneck related to the removal of elements from the middle of the queue. Also fixes a subtle bug in ScheduleDAGRRList::CapturePred: It was updating the state of the SUnit before removing it. As a result, the comparison operators were working incorrectly and this SUnit could not be removed from the queue properly. Reviewed by Evan and Dan. Approved by Dan. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@50412 91177308-0d34-0410-b5e6-96231b3b80d8

* Implement a signficant optimization for inline asm:Chris Lattner2008-04-271-4/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | When choosing between constraints with multiple options, like "ir", test to see if we can use the 'i' constraint and go with that if possible. This produces more optimal ASM in all cases (sparing a register and an instruction to load it), and fixes inline asm like this: void test () { asm volatile (" %c0 %1 " : : "imr" (42), "imr"(14)); } Previously we would dump "42" into a memory location (which is ok for the 'm' constraint) which would cause a problem because the 'c' modifier is not valid on memory operands. Isn't it great how inline asm turns 'missed optimization' into 'compile failed'?? Incidentally, this was the todo in PowerPC/2007-04-24-InlineAsm-I-Modifier.ll Please do NOT pull this into Tak. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@50315 91177308-0d34-0410-b5e6-96231b3b80d8
