Bug#983927: gsequencer: ftbfs with -march=x86-64-v2
Package: src:gsequencer
Version: 3.7.38-1
Severity: minor
User: debian-gcc@lists.debian.org
Usertags: ftbfs-x86-64-v2
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-v2.
To reproduce these issues, append -march=x86-64-v2 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 last lines of the build log are at the end of this report.
