--- Comment #4 from Richard Biener <rguenth at gcc dot gnu.org> ---
Trying to work around my stage1 issue with the patch below results in a link
failure of at least gnatlink in stage3:
../../xgcc -B../../ -c -g -O2 -W -Wall -gnatpg -gnata -I- -I../rts -I.
-I/space/rguenther/src/gcc-14-branch/gcc/ada -gnatws -gnatyN \
b_gnatl.adb -o b_gnatl.o
../../xg++ -B../../ ... b_gnatl.o ... -pie -ldl
/usr/lib64/gcc/x86_64-suse-linux/7/../../../../x86_64-suse-linux/bin/ld:
b_gnatl.o: relocation R_X86_64_32S against `.rodata' can not be used when
making a PIE object; recompile with -fPIE
and yeah, you can see that b_gnatl.o was not built with -fPIE!? That's also
true for other objecs referenced. Note this particular experiment was done
on the gcc-14 branch.
