Comment(by fbissey):
I will check that. The main problem in mpir is there is some code in yasm
assembler and some in GNU assembler (and some more in C but these are not
a problem) depending on the CPU.
In Gentoo we apply the following to the source of mpir-2.X.X:
{{{
for i in $(find . -type f -name '*.asm') ; do
# TODO: why does this not work without the following echo
???
echo $i >/dev/null
cat >> $i <<-EOF
#if defined(__linux__) && defined(__ELF__)
.section .note.GNU-stack,"",%progbits
#endif
EOF
done
for i in $(find . -type f -name '*.as') ; do
echo $i >/dev/null
cat >> $i <<-EOF
%ifidn __OUTPUT_FORMAT__,elf
section .note.GNU-stack noalloc noexec nowrite
progbits
%endif
EOF
done
}}}
We do this following the recommendation from
[http://www.gentoo.org/proj/en/hardened/gnu-stack.xml]
The file naming is somewhat reverse from what we expected if I remember
well.
