From afdbd6d03b32209a99c57bfe2ee96e87a58a25bc Mon Sep 17 00:00:00 2001 From: Chris Demetriou Date: Thu, 1 Nov 2001 01:33:47 +0000 Subject: [ bfd/ChangeLog ] 2001-10-31 Chris Demetriou * elf32-mips.c (_bfd_mips_elf_hi16_reloc): Handle PC-relative relocations properly. [ gas/ChangeLog ] 2001-10-31 Chris Demetriou * config/tc-mips.c (HAVE_32BIT_ADDRESSES): If compiling embedded PIC code, assume pointers the same size as GPRs. (macro): In M_LA_AB handling for embedded PIC code, support "la $treg,foo-bar($breg)". In load/store handling (label ld_st) support " $treg,-($breg)" which is used by the compiler for switch statements. In load/store double multi-instruction macro handling (label ldd_std) add a comment that no special handling is currently done for embedded PIC. (mips_ip): In 'o' (16-bit offset) case, only accept 16 bit offsets.
