Thus when writing the output we get a dramatic slowdown due to commit 014a602b86. PR 30724 * bfd.c (enum bfd_last_io): New. (struct bfd): Add last_io field. * bfd-in2.h: Regenerate. * bfd-io.c (bfd_bread, bfd_bwrite): Force seek if last_io is opposite direction. (bfd_seek): Reinstate optimisation for seek to same position. -- You are receiving this mail because: You are on the CC list for the bug.
