2001-07-03Fix mips16 testsuite failure by allowing finalize_syms to be set beforeNick Clifton1-3/+13
size_segs is called.
2001-06-27Do not set finalize_syms until after the segments have been sized.Nick Clifton1-3/+6
Some backends may still need to access the syms's frags in order to adjust relaxed frags.

subtract MD_PCREL_FROM_SECTION for 68k. (fixup_segment <Difference of 2 syms different seg>): Only fudge by adding MD_PCREL_FROM_SECTION for 68k or if not already pcrel.
2001-06-27 * write.c (fixup_segment <Difference of 2 syms same seg>): IfAlan Modra1-2/+4
pcrel, subtract MD_PCREL_FROM_SECTION value.
2001-05-27 * write.c (relax_segment <rs_space>): Check the section of aAlan Modra1-1/+1
symbol to determine whether it is absolute rather than comparing its frag against zero_address_frag as listings play tricks with frags.
2001-05-26 * write.c (relax_segment <rs_space>): Calculate growth usingAlan Modra1-15/+21
addresses before stretch. Prevent repeated error messages. From Peter Jakubek <pjak@snafu.de> Use as_bad_where and as_warn_where to pinpoint errors.
