LLVM issuse:AArch64 TargetParser
Hi, A64 versus A32/T32 code generation is controlled by the -target option which I don’t believe is under discussion here.

Therefore armv8a can not be used to imply

Hi Bradley, That's a good point. But also, what does "armv8a"

[LLVMdev] TargetParser - Always build all table-gen files?
Hi Folks, I'm back looking at the target parser that we discussed last year, and I have some questions. http://lists.cs.uiuc.edu/pipermail/cfe-dev/2014-August/038699.html There is no way I can create a target-independent parser in lib/Target without re-encoding all the information about the targets that we already have in the table-gen files on all targets' directories. Doing that would

I hope this ends up being a much larger infrastructure to query for target support, not just parsing strings (which we can cope with duplication), but defining architectural behaviour,

Thanks very much, Renato! I looked into the regressions, there're many cases have similar context as the case I mentioned but N just has only one use. In this case, the canonicalisation won't make it more profitable, will only prevent the possible folding or make the sequence is not expected. The regressions be eliminated, after I limit the expanding to not "N->hasOneUse()".

[RFC] New Clang target selection options for ARM/AArch64
Hi, Below is a document detailing changes we'd like to make to Clang/LLVM to improve the usability of the target options for ARM and AArch64. To keep things simple the proposed changes are listed at the start and you can find the supporting examples at the end of the document. I look forward to your feedback. Thanks, David Spickett.

[RFC] Making -mcpu=generic the default for ARM armv7a and arm8a rather than -mcpu=cortex-a8 or -mcpu=cortex-a53
Motivation At the moment, when targeting armv7a, clang defaults to generate code as if -mcpu=cortex-a8 was specified. When targeting armv8a, it defaults to generate code as if -mcpu=cortex-a53 was specified. This leads to surprising code generation, by the compiler optimizing for a specific micro-architecture, whereas the intent from the user was probably to generate code that is

[RFC] Making -mcpu=generic the default for ARM armv7a and arm8a rather than -mcpu=cortex-a8 or -mcpu=cortex-a53
Thanks for everyone giving their feedback! I saw pretty unanimous support for making -mcpu=generic the default and making -mcpu=generic schedule for an in-order CPU (Cortex-A8 in this case). I'll be making those changes shortly. I think the comments also make clear that it's less obvious whether we'd want -mcpu=native to become a default. It's probably good for some use cases, but

Logical test and look up table
Dear R users, I have a data frame with one column (4000 rows) containing name codes (factor with 63 levels). I would like to associate each name with a particular Type (coded as 1,2,3,4,H or H1) in a second column. Is it possible to do a lookup table of associations (i.e. A23 is of type 1, A13 is of type 3 ...) so as to fill up automatically the $Type column. df() $Source $Type A23 A24 A9 A32

Issuse installing either i386 or x86_64
Greetings - Has anyone ever managed to install 4.2 on a Sony Vaio desktop, model VGC-RB53 ? I can install either mentioned - but on bottup after the install, I get a kernel panic and it just hangs. For that matter, it does the same if I try FC4 - TIA -- Best regards, Chris Never create a problem for which you do not have the answer.
