From a quick glance over elf32-hppa.c it looks to me like R_PARISC_SEGREL32 indeed should not be made dynamic. So I'm wondering if debian hppa-ld has some added features? -- You are receiving this mail because: You are on the CC list for the bug. ___ bug-binutils mailing list bug-binutils@gnu.org https://lists.gnu.org/mailman/listinfo/bug-binutils

Possibly, this has to do with following lines in emulparams/hppalinux.sh:
