* Extensive changes to permit symbols to contain any expression type and to delay the computation of the expression until the value is actually needed. This permits setting symbols to values calculated based on object code size. Expressions were changed to no longer be in a section, to stop the overloading of segment and expression type that previously occurred. * as.c (big_section, pass1_section, diff_section, absent_section): Removed. (expr_section): Added (used for dummy symbols which hold intermediate expression values). (perform_an_assembly_pass): Create expr_section, do not create the sections now removed. * as.h (segT): Removed SEG_ABSENT, SEG_PASS1, SEG_BIG, and SEG_DIFFERENCE. Added SEG_EXPR. (SEG_NORMAL): Corresponding changes. * subsegs.c (seg_name, subsegs_begin): Changed accordingly. * write.c (write_object_file): Ditto. * config/obj-aout.c (seg_N_TYPE): Ditto. * config/obj-bout.c (seg_N_TYPE): Ditto. * config/obj-coff.c (seg_N_TYPE): Ditto. * config/obj-coffbfd.c (seg_N_TYPE): Ditto. * config/obj-vms.c (seg_N_TYPE): Ditto. * expr.h (operatorT): Moved in from expr.c, added some values.
