My bad for not looking further. I'm still somewhat confused though. MOVCCr gets expanded in the ARMExpandPseudoInsts pass, and it still seems only a case of one instruction replacing the other. My worry of emitting two instructions, is that a dead code pass will eliminate the first instruction cause it thinks the second instruction is defining the same register. -Dilan On Fri, Jul 7, 2017

Hi Evan, Thanks for your feedback! 2009/1/7 Evan Cheng <evan.cheng at apple.com>: > > On Jan 7, 2009, at 2:48 AM, Roman Levenstein wrote: > > > As you can see, PrologEpilogInserter has inserted at the beginning > of the function some code for manipulation of the frame pointer and > this inserted code uses the LR register. > As far as I understand,

Hi,   For a custom target, there is a pass to perform memory dependence analysis, where, i need to get memory pointer for "load instruction". I want to check the pointer alias behavior. I am getting this by considering the memoperands for the load instruction.   For "load instruction", Machine Instruction dumps as below:   vr12<def> = LD_Iri %vr2<kill>, 0;

Thanks for the response! This would be really helpful because we use a lot of old adobe type 1 fonts that are 100% resource fork and are rendered unusable without the marshalled xattr's in addition to the AFP_ streams. While ideally having it seamlessly integrated into samba would be great, if it's easier to run a one-time conversion utility we can do that too. Thanks! -S On Wed, Apr
