similar to: Defining intrinsic with arbitrary number of parameter?

+ Alexey Anastasia According to SPIR spec v1.2 s2.10.3 2.10.3 The printf function The printf function is supported, and is mangled according to its prototype as follows: int printf(constant char * restrict fmt, ... ) Note that the ellipsis formal argument (...) is mangled to argument type specifier z It seems printf should be mangled. Alexey/Anastasia, What do you think? Thanks. Sam From:

I don't see any problem mangling it to be honest even though there seems to be only one prototype anyways. We could add restrict in as well.

Thanks a lot.

Hongbin, Did you tweak sys.path? # Extend paths to allow loading zorg and config modules. import os, sys path = os.path.join(os.environ.get('HOME'), 'zorg', 'buildbot', 'osuosl', 'master') if path not in sys.path: sys.path.append(path) path = os.path.join(os.environ.get('HOME'), 'zorg') if path not in sys.path: sys.path.append(path)

Hi, I had cloned zorg from https://llvm.org/svn/llvm-project/zorg/trunk, then I try to start the buildbot master located in buildbot/osuosl/master (the absolute path is /nfs/home/hongbin.zheng/buildbot/zorg/buildbot/osuosl/master) by simply typing "buildbot start" And I get something like this from my twistd.log: --- <exception caught here> --- File

the packed + aligned attribute will automatically introduce explicit padding byte array: https://godbolt.org/g/TlHX2g Sometimes Clang will decide to automatically pack the struct/class in C++, I don't know the details here, but looks like it is related to inheritance.

Hi Mats, When the struct is packed, explicit byte array is introduced to pad the struct. (I saw this happened in clang 3.9.) I want to check if a byte or byte array in an LLVM struct is introduce for explicit padding or not. I don't need to worry about this problem in case the newest clang do not introduce byte array anymore. Thanks Hongbin On Thu, May 18, 2017 at 1:03 AM, mats petersson

Like I said, i'm nearly positive there is a much faster way, as the sets are mostly shared except in the cyclic case, and in all reducible cyclic cases, removal of back-arcs does not affect dominance (because in any reducible flowgraph, v dominates u whenever u,v is a back-arc) On Tue, Apr 25, 2017 at 7:38 PM, Hongbin Zheng <etherzhhb at gmail.com> wrote: > Hi Daniel, > >

Hi Daniel, Thanks a lot for all these explanation, I will try it out.

R Friends, I'm running R2.7.1 on Windows XP. I'm trying to get some lattice functionality which I have not seen previously documented--I'd like to plot the exact same data in multiple panels but changing the grouping variable each time so that each panel highlights a different feature of the data set. The following code does exactly that with a simple and fabricated air quality data

Hi Steve, Several people told me that LLVM TOT bcreader can read odder version of bitcode without any problem. Do you know the oldest version of bitcode that the TOT bitcode reader supports? Also, why do you generate bitcode instead of the textural representation, i.e. the "ll" file, for older version of LLVM? I guess generating "ll" code is simpler. Another approach I am

Hi, Yes, I can see why that would not work. The sinking algorithm in SimplifyCFG isn't particularly clever. In particular it can't reason about memory ordering and aliasing. In unswitch1(), it can identify that the stores correlate because the correlating stores appear in the same relative source order. In unswitch2() they have been permuted, and the algorithm cannot deal with this. This

Thanks Steve and Mehdi for the explanation. Steve, I am a little be confused by looking at the code in https://android.googlesource.com/platform/frameworks/compile/libbcc/+/master/bcinfo/BitReader_3_0/BitcodeReader.cpp. Looks like the BitcodeReader do some translation while reading the bitcode. If LLVM ToT can read the bitcode of LLVM 3.0, while can't we just use the bitcode reader in LLVM
