Package: libgcrypt20 Version: 1.6.0-2 Severity: serious Tags: sid jessie Looking at the sources, and adding the missing arm source files, you'll see that at least on armhf the neon optimizations are enabled by default. The Debian armhf port is supporting vfp only. If you don't want to disable that for all cases, you may want to provide two implementations and selecting the one needed using the ifunc support provided in recent glibc/gcc versions.
I didn't check armel yet. The configury detects avx and sse features on i386 too. I didn't check if these are then enabled by default too. -- To UNSUBSCRIBE, email to debian-bugs-rc-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
