Binutils with MCST patches
6d45194248
This patch changes rl78-tdep.c so that a 16-bit type is used for register pairs instead of a pointer type as was previously the case. This will cause these register pairs to be displayed as integers instead of as a data address with a 0xf0000 ORed in. E.g. registers ax, bc, de, and hl might now be displayed like this: (gdb) info registers ax bc de hl ax 0x6 6 bc 0x0 0 de 0x10c3 4291 hl 0x108d 423 Whereas, before, they were displayed as follows: (gdb) info registers ax bc de hl ax 0xf0006 0xf0006 bc 0xf0000 0xf0000 de 0xf10c3 0xf10c3 hl 0xf108d 0xf108d These pairs are 16 bit quantities and should be displayed as such. This change also affects the way that the banked register pairs are displayed. Within GDB, the banked register pairs are named bank0_rp0, bank0_rp1, .., bank3_rp2, bank3_rp3. However, these register pairs need to be used as addresses in DWARF expressions. I have added 16 pseudo registers corresponding to banked register pairs. These new pseudo registers are all hidden from the user and have a pointer type. Values from these registers are intended to be used in DWARF expressions. Therefore, rl78_dwarf_reg_to_regnum() has been adjusted to return these new pseudo register numbers. I had a much simpler patch which only changed the types, but it showed a number of regressions due to integer values from the banked register pairs being used as part of an address expression. This current patch shows no regressions and now displays values of register pairs correctly. * rl78-tdep.c ( RL78_BANK0_RP0_PTR_REGNUM, RL78_BANK0_RP1_PTR_REGNUM) (RL78_BANK0_RP2_PTR_REGNUM, RL78_BANK0_RP3_PTR_REGNUM) (RL78_BANK1_RP0_PTR_REGNUM, RL78_BANK1_RP1_PTR_REGNUM) (RL78_BANK1_RP2_PTR_REGNUM, RL78_BANK1_RP3_PTR_REGNUM) (RL78_BANK2_RP0_PTR_REGNUM, RL78_BANK2_RP1_PTR_REGNUM) (RL78_BANK2_RP2_PTR_REGNUM, RL78_BANK2_RP3_PTR_REGNUM) (RL78_BANK3_RP0_PTR_REGNUM, RL78_BANK3_RP1_PTR_REGNUM) (RL78_BANK3_RP2_PTR_REGNUM, RL78_BANK3_RP3_PTR_REGNUM): New constants. (rl78_register_type): Use a data pointer type for SP and new pseudo registers mentioned above. Use a 16 bit integer type for all other register pairs. (rl78_register_name, rl78_g10_register_name): Update for new pseudo registers. (rl78_pseudo_register_read): Likewise. (rl78_pseudo_register_write): Likewise. (rl78_dwarf_reg_to_regnum): Return register numbers representing to the newly added pseudo registers. |

README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
