From 2000-04-07 Jonathan Larmour <jlarmour@redhat.co.uk>:
|
||||
* mips-tdep.c (saved_gpreg_size_enums): Define enum command for
|
||||
new "set mips saved-gpreg-size" command
|
||||
(MIPS_SAVED_REGSIZE): Now a function mips_saved_regsize()
|
||||
(MIPS_DEFAULT_SAVED_REGSIZE): Define for default MIPS_SAVED_REGSIZE,
|
||||
either from target, or gdb multi-arch
|
||||
(show_mips_command): New. For "show mips" prefix command
|
||||
(set_mips_command): New. For "show mips" prefix command
|
||||
(_initialize_mips_tdep): Add top-level mips prefix command
|
||||
Add "set mips saved-gpreg-size" command
|
||||
|
||||
* mips-tdep.c (struct gdbarch_tdep): Rename mips_saved_regsize to
|
||||
mips_default_saved_regsize.
|
||||
(mips_gdbarch_init): Update.
|
||||
(MIPS_DEFAULT_SAVED_REGSIZE): Update.
|
||||
(mips_gdbarch_init): Use MIPS_REGSIZE as the default value for
|
||||
mips_default_saved_regsize.

that could indicate -gp32 BUT gas/config/tc-mips.c contains the
|
||||
comment:
|
||||
|
||||
``We deliberately don't allow "-gp32" to set the MIPS_32BITMODE
|
||||
flag in object files because to do so would make it impossible to
|
||||
link with libraries compiled without "-gp32". This is
|
||||
unnecessarily restrictive.
|
||||
|
||||
We could solve this problem by adding "-gp32" multilibs to gcc,
|
||||
but to set this flag before gcc is built with such multilibs will
|
||||
break too many systems.''
|
||||
|
||||
But even more unhelpfully, the default linker output target for
|
||||
mips64-elf is elf32-bigmips, and has EF_MIPS_32BIT_MODE set, even
|
||||
for 64-bit programs - you need to change the ABI to change this,
|
||||
and not all gcc targets support that currently. Therefore using
|
||||
this flag to detect 32-bit mode would do the wrong thing given
|
||||
the current gcc - it would make GDB treat these 64-bit programs

as 32-bit programs by default. */
