On openSUSE Tumbleweed I run into this for the dwarf assembly test-cases, and
some hardcoded assembly test-cases:
...
Running gdb.dwarf2/fission-absolute-dwo.exp ...
gdb compile failed, ld: warning: fission-absolute-dwo.o: \
missing .note.GNU-stack section implies executable stack
ld: NOTE: This behaviour is deprecated and will be removed in a future \
version of the linker
=== gdb Summary ===
# of untested testcases 1
...
Fix the dwarf assembly test-cases by adding the missing .note.GNU-stack in
proc Dwarf::assemble.
Fix the hard-coded test-cases using this command:
...
$ for f in $(find gdb/testsuite/gdb.* -name *.S); do
if ! grep -q note.GNU-stack $f; then
echo -e "\t.section\t.note.GNU-stack,\"\",@progbits" >> $f;
fi;
done
...
Likewise for .s files, and gdb/testsuite/lib/my-syscalls.S.
The idiom for arm seems to be to use %progbits instead, see commit 9a5911c08b
("gdb/testsuite/gdb.dwarf2: Replace @ with % for ARM compatability"), so
hand-edit gdb/testsuite/gdb.arch/arm-disp-step.S to use %progbits instead.
Note that dwarf assembly testcases use %progbits as decided by proc _section.
Tested on x86_64-linux.
