are in the .plt section. * minsyms.c (lookup_solib_trampoline_symbol_by_pc, find_solib_trampoline_target): New functions for handling stepping into -g compiled shared libraries. * symtab.h (lookup_solib_trampoline_symbol_by_pc, find_solib_trampoline_target): Add prototypes. * config/tm-sunos.h (IN_SOLIB_TRAMPOLINE, SKIP_TRAMPOLINE_CODE): Define to handle stepping into -g compiled shared libraries. * config/tm-sysv4.h (SKIP_TRAMPOLINE_CODE): Define to handle stepping into -g compiled shared libraries. * configure.in: Add mips-*-sysv4* support. * config/mips/mipsv4.mh, config/mips/mipsv4.mt, config/mips/tm-mipsv4.h, config/mips/xm-mipsv4.h, mipsv4-nat.c: New files for MIPS SVR4 support. * Makefile.in: Update for new mipsv4 files. * alpha-tdep.c (heuristic_proc_desc, find_proc_desc): Use read_next_frame_reg to obtain the frame relative stack pointer. * mips-tdep.c (heuristic_proc_desc): Use read_next_frame_reg to obtain the frame relative stack pointer. * mdebugread.c (parse_partial_symbols, psymtab_to_symtab1): Handle stStatic and stStaticProc symbols in stabs-in-ecoff output by entering them into the minimal symbol table. * printcmd.c (print_scalar_formatted): Do not try to unpack to a long for float formats. * solib.c: Include "elf/mips.h" only if DT_MIPS_RLD_MAP does not get defined in <link.h>. * solib.c (solib_add): Add shared library sections to the section table of the target before adding the symbols. * partial-stab.h: Relocate static and global functions. * dbxread.c (read_dbx_symtab): Remove unused variable end_of_text_address. Relocate text_addr when passing it to end_psymtab. For Alpha OSF/1 targets, enable gdb to set breakpoints in shared library functions before the executable is run. Retrieve dynamic symbols from stripped executables. * mipsread.c (read_alphacoff_dynamic_symtab): New function. * mipsread.c (mipscoff_symfile_read): Use it. Issue warning message if no debugging symbols were found. * alpha-tdep.c (alpha_skip_prologue): Silently return the unaltered pc if memory at the pc is not accessible and GDB_TARGET_HAS_SHARED_LIBS is defined. * config/alpha/nm-alpha.h (GDB_TARGET_HAS_SHARED_LIBS): Define, OSF/1 has shared libraries.
