On hppa-linux, the change introduces the following regressions in the
gas testsuite:
FAIL: CFI on hppa
FAIL: CFI common 1
FAIL: CFI common 2
FAIL: CFI common 3
FAIL: CFI common 4
FAIL: CFI common 5
FAIL: CFI common 6
The failures are a result of the following warning from readelf:
readelf: Warning: unable to apply unsupported reloc type 9 to section .eh_frame
dave@mx3210:~/gnu/binutils/objdir/gas/testsuite$ ../as-new -o dump.o /home/dave/gnu/binutils/src/gas/testsuite/gas/cfi/cfi-common-2.s
dave@mx3210:~/gnu/binutils/objdir/gas/testsuite$ readelf -r dump.o|less
Relocation section '.rela.eh_frame' at offset 0x274 contains 1 entries:
Offset Info Type Sym.Value Sym. Name + Addend
0000001c 00000109 R_PARISC_PCREL32 00000000 .text + 0
R_PARISC_PCREL32 is reloc 9. Before the change, the reloc was R_PARISC_NONE.
