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

[LLVMdev] backend question
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?
Sincerely,

[LLVMdev] How to write up XXInstFormat.td?
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.

[LLVMdev] How to write up XXInstFormat.td?
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.

[LLVMdev] Typos in ARMInstrInfo.td ?
Hi,
I think there are a set of typos in the ATOMIC_LOAD_UMIN_I* and
ATOMIC_LOAD_UMAX_I*
pseudo-instructions .
Specifically,

(outs GPR:$dst), (ins GPR:$ptr, GPR:$val), NoItinerary,
[(set GPR:$dst, (atomic_load_min_32 GPR:$ptr, GPR:$val))]>;

[LLVMdev] Lower CFI IDs Using Target Intrinsic
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

Find missing days

I have a data.frame like this:

[LLVMdev] Questions on ARMInstrInfo.td and MC/ARM/ELF
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?

How to assign the same levels to a dataframe column?
Hello,
I have a dataframe df with a column x that has these unique values:
"L" "M" "V" "N" "H". I can assign a factor to it:
```
df$x = as.factor(df$x)
> [1] L M V N H
Levels: H L M N V

I now need to get a subset of this dataframe. I could do the same
thing as before on the subset sf, but I would like to avoid the

Draw level lines on the surface of a bivariate function
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
