From: David S. Miller Date: Sat, 13 Feb 2010 00:01:20 +0000 (+0000) Subject: * output.h (Output_reloc::Output_reloc): Add X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=0da6fa6c5b5a2b4fc5b64fbae25ccd9509210860;p=binutils-gdb.git * output.h (Output_reloc::Output_reloc): Add is_symbolless parameter. (Output_reloc::is_symbolless): New. (Output_reloc::is_symbolless_): New. (Output_reloc::type_): Decrease to 29 bits. (Output_reloc::Output_reloc): Add is_symbolless parameter. (Output_reloc::is_symbolless): New. (Output_data_reloc::add_global): Handle is_symbolless. (Output_data_reloc::add_global_relative): Likewise. (Output_data_reloc::add_local): Likewise. (Output_data_reloc::add_local_relative): Likewise. (Output_data_reloc::add_symbolless_global_addend): New. (Output_data_reloc::add_symbolless_local_addend): New. * output.cc (Output_reloc::Output_reloc): Handle is_symbolless. (Output_reloc::set_needs_dynsym_index): Test ->is_symbolless_ instead of ->is_relative_ (Output_reloc::write): Likewise. (Output_reloc::get_symbol_index): Return 0 when ->is_symbolless_ (Output_reloc::write_rel): Simplify. * sparc.cc (Target_sparc::Scan::local): Use ->add_symbolless_local_addend as needed. (Target_sparc::Scan::global): Use ->add_symbolless_global_addend as needed. Also, emit appropriate unaligned vs. aligned dynamic reloc based upon relocation offset. --- diff --git a/gold/ChangeLog b/gold/ChangeLog index 0b50eadca79..936d0b9e366 100644 --- a/gold/ChangeLog +++ b/gold/ChangeLog @@ -1,3 +1,32 @@ +2010-02-12 David S.
