Added Irix 5 support. * configure.in (mips-sgi-irix5*): New host and target. Use irix5 for both. * config/mips/irix5.mh, config/mips/irix5.mt, config/mips/xm-irix5.h, config/mips/nm-irix5.h, config/mips/tm-irix5.h, irix5-nat.c: New files for Irix 5 support. * mdebugread.c: New file, split out of mipsread.c. Added elfmdebug_build_psymtabs routine. Added some checks on external symbols. Changed code to keep ecoff_debug_info and ecoff_debug_swap structs in the psymtab and in global pointers rather than retrieving them from the bfd. Also changed to keep the pending list with the psymtab rather than the objfile (each psymtab for a single objfile points to the same pending list). * mipsread.c: Bulk of file moved into mdebugread.c, leaving just the sym_fns. * Makefile.in (SFILES): Added mdebugread.c. (OBS): Added mdebugread.o. (mdebugread.o): New target. * symfile.h: Declare mdebug_build_psymtabs and elfmdebug_build_psymtabs. * elfread.c (struct elfinfo): Added mdebugsect field. (elf_locate_sections): Remember location of .mdebug section. (elf_symfile_read): Call elfmdebug_build_psymtabs on .mdebug section. * infrun.c (AT_FUNCTION_START): Set to 0 if not already defined. (wait_for_inferior): Use AT_FUNCTION_START if it is defined to see if PC is at the start of a function. * mips-tdep.c (read_next_frame_reg): Use SIGFRAME_REG_SIZE, and give it a default definition. (mips_skip_prologue): Skip instructions which initialize $gp register. (in_sigtramp): New procedure, moved in from mipsread.c. * config/mips/tm-mips.h: Declare in_sigtramp.

Added Irix 5 support. * configure.in (mips-sgi-irix5*): New host and target. Use irix5 for both. * config/mips/irix5.mh, config/mips/irix5.mt, config/mips/xm-irix5.h, config/mips/nm-irix5.h, config/mips/tm-irix5.h, irix5-nat.c: New files for Irix 5 support. * mdebugread.c: New file, split out of mipsread.c. Added elfmdebug_build_psymtabs routine. Added some checks on external symbols. Changed code to keep ecoff_debug_info and ecoff_debug_swap structs in the psymtab and in global pointers rather than retrieving them from the bfd. Also changed to keep the pending list with the psymtab rather than the objfile (each psymtab for a single objfile points to the same pending list). * mipsread.c: Bulk of file moved into mdebugread.c, leaving just the sym_fns. * Makefile.in (SFILES): Added mdebugread.c. (OBS): Added mdebugread.o. (mdebugread.o): New target. * symfile.h: Declare mdebug_build_psymtabs and elfmdebug_build_psymtabs. * elfread.c (struct elfinfo): Added mdebugsect field. (elf_locate_sections): Remember location of .mdebug section. (elf_symfile_read): Call elfmdebug_build_psymtabs on .mdebug section. * infrun.c (AT_FUNCTION_START): Set to 0 if not already defined. (wait_for_inferior): Use AT_FUNCTION_START if it is defined to see if PC is at the start of a function. * mips-tdep.c (read_next_frame_reg): Use SIGFRAME_REG_SIZE, and give it a default definition. (mips_skip_prologue): Skip instructions which initialize $gp register. (in_sigtramp): New procedure, moved in from mipsread.c. * config/mips/tm-mips.h: Declare in_sigtramp.
