[Debian-astro-maintainers] Bug#983947: libsharp: ftbfs with -march=x86-64-v3

Wed Mar 3 15:39:15 GMT 2021

Package: src:libsharp
Version: 1.0.0-2
Severity: minor
User: debian-gcc at lists.debian.org
Usertags: ftbfs-x86-64-v3

Starting with LLVM 12 and GCC 11 (and backported to gcc-10 for Debian), 
GCC introduces optimizations for new micro-architecture levels from
the x86-64 psABI.  Filing these bug reports for packages building with
the current level (x86-64), but not with x86-64-v3.

To reproduce these issues, append -march=x86-64-v3 to the compiler
flags (CFLAGS, CXXFLAGS, ...).  You also need hardware supporting these.
The easiest way is to call the dynamic linker in glibc 2.33 like
  /lib/x86_64-linux-gnu/ld-linux-x86-64.so.2 --help
Otherwise look at the flags in /proc/cpuinfo and compare these with
those from table 3.1 in the System V Application Binary Interface doc:
https://gitlab.com/x86-psABIs/x86-64-ABI/-/wikis/x86-64-psABI

Please don't upload a package setting these flags by default.  The
x86-64 baseline is still unchanged.

The full build log can be found at:
http://people.debian.org/~doko/logs/20210228/filtered/gcc10-v3/libsharp_1.0.0-2_unstable_gcc10-v3.log
The last lines of the build log are at the end of this report.
