  Hi,

This patch series resolves two PRs related to relocatable links
involving SFrame sections:

PR ld/32666 - Incorrect .rela.sframe when using ld -r
PR libsframe/32589 - function start address is zero in SFrame section dump

The series also addresses a thinko in GAS/ld.bfd related to SFrame FDE
func_start_addr.

I will post my notes on why this series is an RFC separately next.

Thanks,
Indu Bhagat (4):
  gas: ld: sframe: fix RELA r_offset handling
  objdump, readelf: sframe: apply relocations before textual dump
  ld: bfd: sframe: fix incorrect r_offset in RELA entries
  ld: bfd: sframe: fix incorrect r_addend in RELA entries
