Ah, I think I get it now. This was mentioned earlier in the thread, but it didn't click at the time. It sounds like I can do instruction selection with a pattern like (omitting selection of the sources): let Constraints = "$dst = $oldvalue" in { def MASKEDARITH : MyInstruction< (outs VectorReg:$dst), (ins MaskReg:$mask, VectorReg:$src1, VectorReg:$src2, VectorReg:$oldvalue), "add $dst {$mask}, $src1, $src2", [(set v16i32:$dst, (vselect v16i1:$mask, (add v16i32:$src1, v16i32:$src2)...

...;select' is the proper way to implement predication. I believe the predicated form cannot be explicitly expressed in LLVM asm, because it is SSA. It can be done implicitly: %sum = add <16 x i32> %x, %y %newvalue = select <16 x i1> %mask, <16 x i32> %sum, <16 x i32> %oldvalue The issue becomes how to match the instruction form above in a TableGen pattern. In order for this to emit a masked instruction, %newvalue and %oldvalue must be assigned to same physical register (I'm assuming an instruction like 'add %r0{%m0} %r1 %r2') However, I don't think there...

For any operation that can trap (pretty much any fp operation) you also need to protect the inputs with safe values to adhere to the semantics of the LLVM IR. For an fadd, for example: %tx = select %mask, %x, <0.0, 0.0, 0.0 ...> %ty = select...

Since there are no constructors for Value, how do you properly insert a new Value? If I create a pointer Value *newValue and then call AA.copyValue(oldValue, newValue), this does not work, since newValue is not allocated. -------------- next part -------------- An HTML attachment was scrubbed...

AA.copyValue is used to tell the AliasAnalysis that a transformation is replacing the instruction in oldValue with newValue, so AA should update its internal tables.

Hi, Has anyone successfully implemented the :onsubmit option for form_remote_tag. It doesn''t seem to work for me. Is there any specific version of rails which is required for the same. Here''s my piece of code. <script> function set_tojid(){ alert(''onsubmit''); } </script> <%= form_remote_tag :update => '''', :url => {
