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

I have a question about the SSE scalar convert intrinsics. cvtsd2si is defined thusly: def int_x86_sse2_cvtsd2si64 : GCCBuiltin<"__builtin_ia32_cvtsd2si64">, Intrinsic<[llvm_i64_ty, llvm_v2f64_ty], [IntrNoMem]>; This matches the signature of the GCC intrinsic. The fact that the GCC intrinsic has a type mismatch on the input (vector rather than scalar) is

I don't think the standard forbids you to call 0, but it makes calling 0 undefined behavior ("behavior, upon use of a nonportable or erro...

You can join a Windows Server to a Samba4 Domain controller and set up the WSUS server role and it should work. HOWEVER, if you are going to point all 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

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

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

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. --

...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, Ma...

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. Unfortunately, it is not clear that I can get OpenSSH to use PKI authentication.

...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 l...

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 departm...

I was hoping to introduce a new top level library in llvm/lib/Frontend for code that is (mainly) used by LLVM frontends but not by one exclusively. At first, I would place the OpenMP-IR-Builder [1] (and related code [0]) there. This Builder translates "OpenMP directives" to LLVM-IR and is supposed to be reused in Flang. First, I tried to place the OpenMP-IR-Builder into llvm/IR, right
