[PATCH] SH 2a - Part 1: Basic cpu type and register handling

- Subject: [PATCH] SH 2a - Part 1: Basic cpu type and register handling
- Reply-to: gdb-patches at sources dot redhat dot com
Hi,
this and the following three patches override what Alex already submitted
on 2004-07-29. I decided to split the big SH 2a introduction patch into
four parts, each one easy digestible:
Part 1: Basic cpu type and register handling
Part 2: Prologue and epilogue analyzing
Part 3: Bank register handling
Part 4: Begin using RETURN_VALUE
This is the first patch. It introduces the new target types sh2a and
sh2a_nofpu. The patch concentrates only on the necessary stuff to get
SH 2a in, so it basically only adds functions and structures to support
the new register set. The new register set adds a couple of registers
which require to raise the value of SH_NUM_REGS from 59 to 67.
Another new thing is the register bank capability of the SH 2a. On
interrupt, a couple of registers are saved in the register bank. The
register bank is a stack like on-chip storage, which allows to store
up to 512 register sets in case of nested interrupt processing. A
special instruction (RESBANK) is used to restore registers from the bank.
Two new registers, IBCR (bank control register) and IBNR (bank number
register) are used to control and administer the use of the register
banks. A new pseudo register has been introduced, called "bank", which
allows the user to decide, which bank index is accessed when reading or
writing bank registers. The bank registers are printed with a "b" suffix.
What you see is always the content of the registers in bank "bank".
Changing the value of "bank" changes what you see in the register output.
Changing the value of, say, register r0b changes r0 in bank "bank".
Corinna
Ok, here we go with patch 1:
* sh-tdep.c (SH_NUM_REGS): Define as 67.
(sh_sh_register_name): Add eight empty register names.
(sh_sh3_register_name): Ditto.
(sh_sh3e_register_name): Ditto.
(sh_sh2e_register_name): Ditto.
(sh_sh2a_register_name): New function, defining SH2A register set.
(sh_sh2a_nofpu_register_name): New function, defining SH2A register set
in nofpu case.
(sh_sh_dsp_register_name): Add eight empty register names.
(sh_sh3_dsp_register_name): Ditto.
(sh_sh4_register_name): Ditto.
(sh_sh4_nofpu_register_name): Ditto.
(sh_sh4al_dsp_register_name): Ditto.
(sh2a_show_regs): New function.
(sh2a_nofpu_show_regs): New function.
(sh_sh2a_register_type): New function.
(do_bank_register_info): New function.
(sh_print_pseudo_register): Call do_bank_register_info.
Call sh_print_pseudo_register for valid "bank" register.
(sh_sh2a_register_sim_regno): New function.
(sh_gdbarch_init): Add bfd_mach_sh2a and bfd_mach_sh2a_nofpu handling.
Increment pseudo register count by one for all sh variants with
pseudo registers to accomodate pseudo bank register.
* sh-tdep.h: Add register numbers for R0_BANK0_REGNUM, MACHB_REGNUM,
IVNB_REGNUM, PRB_REGNUM, GBRB_REGNUM, MACLB_REGNUM, BANK_REGNUM,
IBCR_REGNUM, IBNR_REGNUM, TBR_REGNUM and PSEUDO_BANK_REGNUM.
Increment pseudo register numbers.
