against machine architecture stored in the ELF header, to resolve
ambiguities.
* elf32.c (bfd_section_from_shdr): Bfd_make_section can return
NULL, so only use results when non-NULL.
* targets.c (elf32_m68k_vec, elf32_i860_vec): Add extern decls
and add to vector of targets.
* config/obj-ecoff.c, config/obj-ecoff.h: Preliminary ECOFF
support.
* config/tc-mips.h (TARGET_FORMAT): Define based on OBJ_AOUT vs.
OBJ_ECOFF as well as TARGET_BYTES_*_ENDIAN.
(struct loc, struct proc, struct file): Moved to tc-mips.c within
#ifndef OBJ_ECOFF block, since ECOFF uses different versions.
* config/tc-mips.c: Rearranged for ECOFF support. Added
prototypes for all static functions. Moved existing minimal
debugging format support info #ifndef OBJ_ECOFF blocks.
(macro_build_lui): Eliminated sign_extend argument, because ECOFF
does not support a non sign extended high 16 bits reloc. Adjusted
all callers accordingly.
(tc_get_register): Renamed from get_register, and made non-static.
* config/mips-big.mt, config/mips-lit.mt: New files. Define
TARGET_BYTES_BIG_ENDIAN and TARGET_BYTES_LITTLE_ENDIAN,
respectively.
* configure.in (mips-*-bsd*): Use gas_target mips-lit.
(mips-*-ultrix*, mips-*-irix*, mips-*-ecoff): New targets, using
obj_format ecoff and gas_target mips-lit or mips-big.
(pollquit): New function to poll keyboard for user interrupt,
called from QUIT.
* xm-go32.h (QUIT): Define to call pollquit.
* h8300-tdep.c (examine_prologue): Use correct value for number of
registers.
CC_FOR_TARGET instead.
(BASE_FLAGS_TO_PASS): Pass GCC_FOR_TARGET=$(CC_FOR_TARGET).
Also added a sanitized dependency of all-gdb on all-chillrt, so that
the gdb chill tests can be built.
(examine_tag): Use it.
(read_register_stack): Only look in the local registers for a
memory address if it's between rfb and rsp; go to memory otherwise.
* command.c (do_setshow_command): var_uintegers are unsigned.
* sparc-tdep.c (save_insn_opcodes, restore_insn_opcodes):
unsigned, since they use hex values with the high bit set.
(ecoff_write_object_contents): Added BFD_ASSERT calls to ensure
relocs are reasonable.
* coff-msym.c: Eliminated uses of DEFUN.
(ecoff_swap_tir_out): New function.
(AUX_PUT_*): New macros corresponding to the AUX_GET macros.
(ecoff_swap_tir_out): Added prototype.
* mips.h (N_BTMASK, N_TMASK, N_BTSHFT, N_TSHIFT): Define; these
are needed to interpret gcc debugging output.
specific emulation.
* mipsidt.sh: New file; emulation for IDT MIPS board.
* Makefile.in (ALL_EMULATIONS): Added em_mipsidt.o.
(em_mipsidt.c): New target. Uses mipsidt.sh and mips.sc-sh.
* config/mips-idt.mt: New file; sets EMUL to mipsidt.
* configure.in (mips-idt-ecoff): New target; uses mips-idt.
size field a define (DBX_STRINGTAB_SIZE_SIZE). Ensure that the
offset to the string table is nonzero and handle the nonexistant
string table case, should it occur. Ensure that the string table
size read from the file is reasonable, with a minimum lower bound
of DBX_STRINGTAB_SIZE_SIZE instead of zero.
(FLAGS_TO_PASS): Added CXX and CXXFLAGS.
(CC_FOR_TARGET, CXX, CXX_FOR_TARGET): New variables.
(TARGET_FLAGS_TO_PASS): New variable.
(SUBDIRS): Added testsuite.
(all): Build testsuite using TARGET_FLAGS_TO_PASS, so that
testsuite is compiled with CC_FOR_TARGET rather than CC.

(Ultrix 2.2 support from Michael Rendell <michael@mercury.cs.mun.ca>)
* configure.in (vax-*-ultrix2*): New triplet.
* config/vaxult2.mh: New file.
* xm-vaxult2.h: New file.
