As reported here, some versions of LD generates the following warning about executable stacks on our assembly files:

/usr/bin/ld: warning: build/mpn_extras/x86_64/broadwell/
sqrhigh_normalised_hard.lo: missing .note.GNU-stack section implies
executable stack
/usr/bin/ld: NOTE: This behaviour is deprecated and will be removed in a
future version of the linker
Building libflint.so.20.0.0
/usr/bin/ld: warning: build/mpn_extras_merged.lo: requires executable
stack (because the .note.GNU-stack section is executable)

This seems to be consistent with fixes in the Linux kernel. A solution seems to be to push -z noexecstack to the linker.

The text was updated successfully, but these errors were encountered:
