For some instructions this cpu has two flavors: first performs an operation, and the second performs an operation and updates condition codes (carry, zero, overflow, negative etc) based on the outcome. For example: add rd,rs instruction adds the contents of

Thank you very very much for your answer! Am I correct in my understanding that "let Defs = [CPSR]" in the definition of AI1_bin_s_irs multiclass explains the effect of setting conditional codes to the TableGen in ARM's case?

I suggest u grep how this file is used. Since it is included in xxInstrInfo.td and this is its only use, we can conclude that this file does nothng more than defining some helper tablegen classes and we thus can totally move these definitions into xxInstrInfo.td and then remove XXInstFormat.td Regards. 在 2013-2-6 下午4:52，"陳韋任 (Wei-Ren Chen)" <chenwj at iis.sinica.edu.tw>写道： >

Hi all, I have some troubles in writing XXInstFormat.td for my little backend. I don't know how should I start writing up this file. Is there any general rule? Thanks.

Besizes, XXInstFormat.td usually represents how ISA is grouped in the manual. 在 2013-2-7 上午12:31，"Triple Yang" <triple.yang at gmail.com>写道： > I suggest u grep how this file is used. > Since it is included in xxInstrInfo.td and this is its only use, we can > conclude that this file does nothng more than defining some helper tablegen > classes and we thus can totally

Hi, I think there are a set of typos in the ATOMIC_LOAD_UMIN_I* and ATOMIC_LOAD_UMAX_I* pseudo-instructions . Specifically, def ATOMIC_LOAD_MIN_I32 : PseudoInst< (outs GPR:$dst), (ins GPR:$ptr, GPR:$val), NoItinerary, [(set GPR:$dst, (atomic_load_min_32 GPR:$ptr, GPR:$val))]>; and def ATOMIC_LOAD_UMIN_I32 : PseudoInst< (outs

Hello, I’m a newbie here, working on a project to enforce Control Flow Integrity (CFI) on programs compiled with LLVM. We’re using LLVM 3.3 so we can leverage poolalloc's dsa analysis. Ideally this will be as target-independent as possible, but our primary target is ARM. One of our passes requires inserting different i32 IDs at various points into the code we’re compiling. As far as I can

Thanks. Fixed with r147032.

Hi Everyone, I am trying to decide on a MC'ized reorg of ARMAsmPrinter for MC/ELF, and had some questions. Currently, it defines quite a few methods like printAddrMode4Operand (linked to ARMInstrInfo.td) that currently assume raw text support in the OutStreamer. Are these methods still supposed to be invoked in the MC'ized path for assembly output? Is JimG's new MC/.s

I could do the same thing as before on the subset sf, but I would like to avoid the possibility that not all

Hello, Is it possible to draw level lines on the surface of a bivariate function? In the following example, to draw surface and levels lines for a multivariate normal law, I use persp, trans3d, contourLines and lines, but if the lines are correctly drawn, some parts of them are, of course, visible even if they are drawn on a non visible "face". Any suggestion to avoid this problem
