Why do you want to call 0? Although a C translation unit may arguably not assign a correspondingly defined function as having a pointer value (address) comparing equal to ((void *) 0); it's not clear that the standard forbids the invocation of such a function, nor does it seem like a good idea to silently strip any such invocations especially if allowed to be sp...

Hello, this mail is to raise awareness of https://reviews.llvm.org/D81728, which is substantial enough of a conceptual change that it should probably at least be mentioned in llvm-dev. InstCombine has dealt with target-specific intrinsics for a long time, since its fix-point iteration is arguably the right place to do so. A downside is that there's a pull to add an increasing amount of code into lib/Transforms/InstCombine/ that really is target-specific. What the aforementioned change does is provide a target hook via TargetTransformInfo, and move the handling of all target intrinsics...

...ot;, [(set GR32:$dst, (int_x86_sse2_cvtsd2si (load addr:$src)))]>; Er, this makes us load a 128-bit quantity, which is almost certainly not what we want. Do we need two intrinsics for these scalar converts, one to satisfy the (arguably broken) GCC interface and one to really reflect the operation as specified by the ISA? -Dave

...ll your devices at the WSUS server, you will require CALs for the devices or the users using them to maintain licensing compliance with Microsoft. At this point, you have paid for the number of Windows Server CALs you need to run actual Active Directory and may as well not use Samba at all as it is arguably less reliable (in some situations) and feature rich than a modern Microsoft AD implementation.

Hi, xencomm is the ppc infrastructure to do hypercalls with guest physical addresses instead of virtual address. Because ia64 should also use physicall address, I think it''s better to re-use the ppc code and to put into common code. I''d propose to submit this patch is every part is OK (ie no NAK). This patch creates include/xen/xencomm_access.h which is to be included by

...is exactly why we should switch to github. It is much easier for new > contributors to start with small fixes. There are two really quite separate issues here: 1) Patches, even trivial ones can sit unreviewed for long periods of time leading to a negative first time contribution experience. 2) Arguably, Phabricator provides a confusing interface for first-time or irregular users. There are efforts to improve this https://secure.phabricator.com/T5000 As for 1), this is something a few of us discussed at the LLVM Cauldron in Hebden Bridge last week which inspired me to give a lightning talk.

Hi all, While we were talking of theora PPA's it occured to me is there somebody who has made a howto to compile libtheora 1.1 alpha support in ubuntu 9.04 Why? 2 reasons . a. Whether we like it or not, Ubuntu is arguably one of the more successful distributions. b. When we compile any software we have the freedom and choice to add in flags which make it better for the individual. -- Regards, Shirish Agarwal My quotes in this email licensed under CC 3.0 http://creativecommons.org/licenses/by-...

...coding tools. There are a few other packages that many would find useful for better coding: devtools, testthat, lintr, codetools, svTools, rbenchmark, pkgutils, etc. This might be some overlap with the HPC task view. I would think that rJava, Rcpp and the like are better suited there but this is arguable. The last time I proposed something like this, Martin deftly convinced me to be the maintainer. It is probably better for everyone if we avoid that on this occasion. * Does anyone else see the need for this? * What other packages fit into this bin? * Would anyone like to volunteer? Thanks, M...

Due to unpleasant (but arguably valid) policy changes at work, any SSH server within the work firewall must accept only PKI authentication. Unless we can convince the higher-ups otherwise, we will also have to use the commercial SSH server within the firewall. Of course, I should be able to use whatever client I like. Unfortunat...

...pet: _foo: .fill 0x100 _bar: .fill _bar - _foo _baz: .fill 0x100 While gas compiles this snippet without any errors, the integrated assembler throws an error: expected absolute expression for _bar - _foo. I haven't found any definition of absolute expression in gas manual, and it's arguable whether this case should be considered an absolute expression, but at the point of evaluating the directive, the addresses of backward labels should be already known so this expression could be treated as absolute. A quick search also revealed several bug reports related to this issue so it seems...

Well, /dev/hwrng may be arguable, although oVirt permits passing it to a VM, of course only on explicit user's request. But how about host devices such as USB and PCI devices? For example <hostdev managed="no" mode="subsystem" type="usb"> <source> <address bus=...

What dbPowerAmp does is encapsulate the wav file into a FLAC container without actually compressing it. I guess it can be a bit arguable if you can technically call it a FLAC file :) It's like using "Store" mode in RAR, for instance. The idea behing this "uncompressed FLAC" is to give the FLAC tagging abilities to people who don't want to compress their files. But as WAV is lacking in the tags depart...

That's what's done for most other instructions, unfortunately. For cvtsd2si, there's currently no "normal" version in the tree, but if you add one, it wouldn't be alone. O...

...ot; to LLVM-IR and is supposed to be reused in Flang. First, I tried to place the OpenMP-IR-Builder into llvm/IR, right next to the llvm::IRBuilder, but it would soon introduce a dependence on other libraries (first TransformUtils) [2]. There are more things (especially parts of Clang) that could arguably be shared across frontends and therefore be moved into a such a dedicated location. If it turns out this is a controversial RFC, we will provide examples and reasons. I hope this is fairly straightforward as this does not introduce any drawbacks (I know of).

I would expect the first one to have middle name either NULL or (in a data.frame context) "", while the second would have NA_character_. In this light, mkString should arguably generate "". i don't think the fact that there is another way to get "" is a particularly large problem. On the other hand, and in support of your position it came up as Michael Lawrence and I were talking about this that asChar from utils.c will give you NA_STRING when y...
