Ohh, that makes sense. And is the reason the first instruction doesn't get deleted because the ExpandPseudoInstructions pass occurs after Register Allocation and machine dead code elimination? -Dilan On Fri, Jul 7, 2017 at 12:37 PM Friedman, Eli <efriedma at codeaurora.org> wrote: > On 7/7/2017 12:10 PM, Dilan Manatunga wrote: > > My bad for not looking further.

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

MachineRegisterInfo is maintaining a list of live-out registers for the MachineFunction. It contains the return value registers, and is typically created by XXXISelLowering::LowerReturn(). Various passes after instruction selection need to look at this list to determine which physical registers are live in return blocks. Eventually, the register allocators copy these live-out registers onto the

Hi Jakob, thanks for the advice. I'll do as you suggest and make sure that CCR is never live. I can use pseudo-instructions to bundle cmp+jump but it's not ideal because I might also have to bundle cmp+jump+jump+... into a pseudo. Also, there are several flavours of cmp instruction so I might need a lot of pseudos. That's what led me to wonder whether MachineInstrBundles might be a

I'm working on an out-of-tree target and am having some problems with rematerialization and spilling. The target's load and store instructions affect the condition code register (CCR). Describing this in the InstrInfo.td file using Defs = [CCR] certainly prevents spills and fills from being inserted where they might clobber CCR but it also prevents the load instruction from being

Hello all, I would like to assign some bits in the instructions, based on the order of mnemonics that appear in a special order. I can do it in TableGen itself, but it will not be well maintainable based on the things I want to accomplish. Therefor, I would like to do it in the c++ file which is waaay easier (at least in the concept!!). Imagine I have this in my base class in TableGen:

Dear Deepayan Sarkar, I have (again) a question concerning "panel" and my function "SplomT", see attachments. Some time ago you helped me to write this function, thanks again. I have used it to great advantage in my statistics instructions. Now the problem I encounter is that the .pdf figure generated in Sweave consists of one extra empty page at the start. This prevents

Dear all, Happy New year! I have used the 'crr' function to fit the 'proportional subdistribution hazards' regression model described in Fine and Gray (1999). dat1 is a three column dataset where: - ccr is the time to event variable - Crcens is an indicator variable equal to 0 if the event was achieved, 1 if the event wasn't acheived due to death or 2 if the event wasn't

Hi, all I want to reduce the checkpoint size of a VM by memory exclusion. I try to find out all the free pages by reference count at VMM-level, As they declared that: /* Page is on a free list: ((count_info & PGC_count_mask) == 0). */ , in struct page_info which is defined in /xen/include/asm-x86/mm.h, but unfortunately, all the pages in a idle VM accords with this condition.

Hello, Good time, I want to write a source code with the model DEA CCR stochastice in R software. But I could not find any example that guides me. I need this model for my article. Where can I find the source code for this model? Is it possible to send me an example of this source code? Help me please. Thanks [[alternative HTML version deleted]]

Hi, Sorry to bother all of you this way, I see no other way at this point. I am trying to get a Siemens Masteguard working and found, by trial and error. Has anyone seen this before? I have the following info: 9600 BAUD 8 bits no parity 1 stop The commands look a lot like the SENA protocol except for the messaging format. It reacts as follows Sending ascii command:

Those CC&Rs may very well be legally void and unenforceable.

Commit 03e0d26fcf79 ("drm/nouveau: slowpath for pushbuf ioctl") included a logic-bug which results in the relocations not actually getting applied at all as the call to nouveau_gem_pushbuf_reloc_apply() is never reached. This causes a regression with graphical corruption, triggered when relocations need to be done (for example after a suspend/resume cycle.) Fix by setting *apply_relocs

Hi, I recently tried to get Samba 3.0.21a running on Solaris 9 several times, using different build environments. The compilers in use where Sun Forte Version 11 and gcc 3.4.2. The binaries where compiled for 64 bit, using CFLAGS="-m64" for gcc for example. I just used configure --prefix=<path> The core file analysis of the latest build shows that strlen() is called: # mdb core
