* powerpc/xmon: Enable disassembly files (compilation changes)Balbir Singh2017-02-151-540/+52
| | | | | | | | | | | | | | | | | | | | | | | | | | After updating ppc-dis.c, ppc-opc.c and ppc.h the following changes were made to enable compilation and working of xmon: 1. Remove all disassembler_info 2. Use xmon's printf/print_address to output data and addresses respectively. 3. All bfd_* types and casts have been removed. 4. Optimizations related to opcd_indices have been removed. 5. The dialect is set based on cpu features. 6. PPC_OPCODE_CLASSIC is no longer supported in the new disassembler. 7. VLE opcode parsing and printing has been stripped. 8. Coding style conventions used for those routines has been retained and it does not match our CodingStyle. 9. The highest supported dialect is POWER9. 10. Defined ATTRIBUTE_UNUSED in ppc-dis.c. 11. Defined _(x) in ppc-dis.c. Finally, we remove the dependency on BROKEN so that XMON_DISASSEMBLY can be enabled again. Signed-off-by: Balbir Singh <bsingharora@gmail.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>

* powerpc/xmon: Update ppc-dis/opc.c and ppc.hBalbir Singh2017-02-151-48/+224
| | | | | | | | | | | | | | | | | | | | Upgrade ppc-opc.c, ppc-dis.c and ppc.h to the versions belonging to the following binutils commit: 65b650b4c7463f4508bed523c24ab0031a5ae5cd * ppc-dis.c (print_insn_powerpc): Don't skip all operands after setting skip_optional. That is the last version of those files that were licensed under GPLv2. This leaves the code in a state that does not compile, because the binutils code needs to be tweaked to work in the kernel. We don't fix that in this commit, because we want to import more binutils changes in subsequent commits. So for now we mark XMON_DISASSEMBLY as BROKEN, so it can't be built.

* powerpc: Move cpu_has_feature() to a separate fileKevin Hao2016-08-011-0/+1
| | | | | | | | | | | | | | | | | We plan to use jump label for cpu_has_feature(). In order to implement this we need to include the linux/jump_label.h in asm/cputable.h. Unfortunately if we do that it leads to an include loop. The root of the problem seems to be that reg.h needs cputable.h (for CPU_FTRs), and then cputable.h via jump_label.h eventually pulls in hw_irq.h which needs reg.h (for MSR_EE). So move cpu_has_feature() to a separate file on its own.

* [POWERPC] Make xmon disassembly optionalMichael Ellerman2006-12-041-2/+1
| | | | | | | | | | | | | | | | | | While adding spu disassembly support it struck me that we're actually carrying quite a lot of code around, just to do disassembly in the case of a crash. While on large systems it's not an issue, on smaller ones it might be nice to have xmon - but without the weight of the disassembly support. For a Cell build this saves ~230KB (!), and for pSeries ~195KB. We still support the 'di' and 'sdi' commands, however they just dump the instruction in hex. Move the definitions into a header to clean xmon.c just a tiny bit. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Arnd Bergmann <arnd.bergmann@de.ibm.com>
* [POWERPC] Prepare for spu disassembly in xmonMichael Ellerman2006-12-041-3/+3
| | | | | | | | | | | | | | | | In order to do disassembly of spu binaries in xmon, we need to abstract the disassembly function from ppc_inst_dump. We do this by making the actual disassembly function a function pointer that we pass to ppc_inst_dump(). To save updating all the callers, we turn ppc_inst_dump() into generic_inst_dump() and make ppc_inst_dump() a wrapper which always uses print_insn_powerpc(). Currently we pass the dialect into print_insn_powerpc(), but we always pass 0 - so just make it a local.

* powerpc: Merge xmonPaul Mackerras2005-10-281-0/+184
The merged version follows the ppc64 version pretty closely mostly, and in fact ARCH=ppc64 now uses the arch/powerpc/xmon version. The main difference for ppc64 is that the 'p' command to call show_state (which was always pretty dodgy) has been replaced by the ppc32 'p' command, which calls a given procedure (so in fact the old 'p' command behaviour can be achieved with 'p $show_state').
