* Calling ReassociateExpression recursively is extremely dangerous since it willDuncan Sands2012-05-081-7/+7
| | | | | | | | | | | | | replace the operands of expressions with only one use with undef and generate a new expression for the original without using RAUW to update the original. Thus any copies of the original expression held in a vector may end up referring to some bogus value - and using a ValueHandle won't help since there is no RAUW. There is already a mechanism for getting the effect of recursion non-recursively: adding the value to be recursed on to RedoInsts. But it wasn't being used systematically. Have various places where recursion had snuck in at some point use the RedoInsts mechanism instead. Fixes PR12169. llvm-svn: 156379

* Ordinary patch for PR1255.Stepan Dyatkovskiy2012-05-083-34/+144
| | | | | | | Added new case-ranges orientated methods for adding/removing cases in SwitchInst. After this patch cases will internally representated as ConstantArray-s instead of ConstantInt, externally cases wrapped within the ConstantRangesSet object. Old methods of SwitchInst are also works well, but marked as deprecated. So on this stage we have no side effects except that I added support for case ranges in BitcodeReader/Writer, of course test for Bitcode is also added. Old "switch" format is also supported. llvm-svn: 156374

* Coalesce subreg-subreg copies.Jakob Stoklund Olesen2012-05-071-14/+25
| | | | | | | | | | | | | | | | | At least some of them: %vreg1:sub_16bit = COPY %vreg2:sub_16bit; GR64:%vreg1, GR32: %vreg2 Previously, we couldn't figure out that the above copy could be eliminated by coalescing %vreg2 with %vreg1:sub_32bit. The new getCommonSuperRegClass() hook makes it possible. This is not very useful yet since the unmodified part of the destination register usually interferes with the source register. The coalescer needs to understand sub-register interference checking first. llvm-svn: 156334
* Add an MF argument to TRI::getPointerRegClass() and TII::getRegClass().Jakob Stoklund Olesen2012-05-0728-47/+69
| | | | | | | | | | | | | The getPointerRegClass() hook can return register classes that depend on the calling convention of the current function (ptr_rc_tailcall). So far, we have been able to infer the calling convention from the subtarget alone, but as we add support for multiple calling conventions per target, that no longer works. Patch by Yiannis Tsiouris! llvm-svn: 156328

* Add TRI::getCommonSuperRegClass().Jakob Stoklund Olesen2012-05-071-0/+71
| | | | | | | | | | | | | | | | | | | | | | | | | | This function is a generalization of getMatchingSuperRegClass() to the symmetric case where both sides are using a sub-register index. It will find a super-register class and sub-register indexes that make this diagram commute: PreA SuperRC ----------> RCA | | | | PreB | | SubA | | | | V V RCB ----------> SubRC SubB This can be used to coalesce copies like: %vreg1:sub16 = COPY %vreg2:sub16; GR64:%vreg1, GR32: %vreg2 llvm-svn: 156317
