OpenBLAS in everyday R?
On point 1):
The standard approach seems to favor the reference BLAS for reasons other
than speed.
For example, vecLib, Apple's multi-threaded BLAS library, is not the
default choice for macOS binaries due to concerns about 'precision'. See:

OpenBLAS in everyday R?
Hi R-devel list,
OpenBLAS is readily available for unix-likes:
https://cloud.r-project.org/web/packages/gcbd/vignettes/gcbd.pdf
However, my questions are:
1) Would R-devel consider using OpenBLAS for the main distribution of R for
all platforms including Windows?
2) If so, would R-devel set the default multi-thread level to the number of
(real) cores on a machine?
My sense is there're a

Please consider re-reading this vignette of mine. BLAS is an interface,
OpenBLAS is but one implementation. R has allowed you to switch between
different implementations for a long time (if you used a

It seems that reproducibility across systems is also an issue with

Ah, you're in luck then: an MSP430 backend was checked in to SVN today

[LLVMdev] leveraging back-end C compiler features in the gcc-based front-end
...lace a call to
__get_SR_register() in my front-end source, and it simply shows up in
the back-end .c file; other "extensions" to compilers (such as
'interrupt' keyword to generate different prologue/epilogue code) would
be a little trickier (though there are presumably already gcc
mechansims for flagging interrupt routines??)<br>

[LLVMdev] [cfe-dev] Unwind behaviour in Clang/LLVM
Hi all,
I feel that there are two problems with the existing infrastructure:
* The nounwind attribute is ambiguous for (1) not throwing exceptions and
(2) not performing stack unwinding. I feel that it will be better to
separate this in two different attributes
* There is some problem when the function has both uwtable and nounwind.
Although, I think it fine to keep the current definition of

"privileged slots"
Hi all,
in the help for RClassUtils I found the expression "privileged slots" in
function "checkSlotAssignment" with the explanation:
/privileged slots (those that can only be set by accesor functions
defined along with the class itself)/
I thought all slots of a (not private) class can be a accessed by a user
via the @ Operator.
Is there a way to make a single slot of a

thank you, i saw this entry. However, this entry is rather

into a package. But I have meant smth else.

input transformations
I spent some time this week trying to add support for input
transformations to the server. I tried a few different approaches. The
patches I've attached are what's currently working best for me.
In this approach I allow every window to have it's own root window
coordinate space. A window's root window coordinate space is affected by
all it's ancestors. Composite clients can

In many cases it's as easy as downloading a new tar source file and adding it to the existing source rpm, doing three seconds of editing on the spec file to account for the new update, and compiling the result.

[LLVMdev] [cfe-dev] Unwind behaviour in Clang/LLVM
I'd love to hear more details. Are you saying that this infinite loop
is a limitation of EHABI table format, and not something that can be
fixed in the compiler?
Meanwhile, please notice that gcc behavior matches current clang
behavior that I described above. We would not want to create an
incompatibility.
