Hi Kostya & Yury, Thanks for the advice.

Hi, # TL;DR I've been building an application with and without the address sanitizer (with gcc 5.3 and clang 3.7.1) and I've observed that the application's behaviour changes (assertion hit/ not hit). I'm wondering if this could be a bug in address sanitizer or if the application I'm running is just buggy (e.g. doing bad things like relying on memory layout, etc.). I'm

Do you use make install DESTDIR to build into your debian directory? This is a general libtool + DESTDIR bug. -Ben

Hi, In buildling XPS using LLVM's makefile system, I'm finding that there's a few things lacking in our support for LLVM-based projects. The items below should help but may require changes to project makefiles. I thought I'd check before just going and doing it. 1. Various autoconf generated v...

John, The following steps should work for you (or anyone buildling on a RedHat box): 1) Get the official OpenSSH source RPM from ftp://ftp.openbsd.org/pub/OpenBSD/OpenSSH/portable/rpm/SRPMS/openssh-3.7.1p2-1.src.rpm 2) Do 'rpmbuild --rebuild ./openssh-3.7.1p2-1.src.rpm' from where you saved the file. 3) This should create the following files in /usr/...

...nding that Tktable and BWidget source (both on sourceforge) are under BSD, like the other Tcl already included with R. Of course some would say that you can build faster and smaller Tcl libraries using Visual C++. I didn't notice much difference with my application running Tktable. I did try buildling Tcl/Tk with the free version of VC++.NET SDK but nmake -f makefile.vc in Tcl_source/win/ complained that vcvars32.bat needed to be run. The latest version of the (free) VC++.NET SDK seems to only have sdkvars.bat, which does something similar to vcvars32.bat (i.e. set PATH, INCLUDE, LIB and NetSam...

For RISC-V V and VE being explicit about %evl is important for performance & correctness and that is what VP does. The get.active.lane.mask intrinsic is used as a hint for the MVE, SVE backends to use hardware tail-predication (the backends reverse engineer that hint by pattern matching for get.active.lane.mask in the mask parameter of "some" masked intrinsics). IMHO, it's more
