* ld.texinfo (Expression Section): Describe treatment of numbers
and absolute symbols. * ldemul.c (after_open_default): Look up __ld_compatibility. * ldexp.c (fold_name): Convert absolute symbols to numbers when inside output section definitions, or when __ld_compatibility >= 221. (exp_fold_tree_1): Convert numbers to absolute when not in output section definition and __ld_compatibility < 221. Don't always convert values outside an output section definition to absolute. * ldexp.h (uses_defined): Comment. * ldlang.c (ld_compatibility): New variable. * ldlang.h (ld_compatibility): Declare. * emultempl/aix.em, * emultempl/armcoff.em, * emultempl/beos.em, * emultempl/elf32.em, * emultempl/genelf.em, * emultempl/lnk960.em, * emultempl/m68kcoff.em, * emultempl/mmo.em, * emultempl/pe.em, * emultempl/pep.em, * emultempl/sunos.em, * emultempl/z80.em: Call after_open_default from after_open function.
