Currently prefixed instructions are dumped as two separate word instructions. Use mread_instr() so that prefixed instructions are read as such and update the incrementor in the loop to take this into account. 'dump_func' is print_insn_powerpc() which comes from ppc-dis.c which is taken from binutils. When this is updated prefixed instructions will be disassembled. Currently dumping prefixed instructions looks like this: 0:mon> di c000000000094168 c000000000094168 0x06000000 .long 0x6000000 c00000000009416c 0x392a0003 addi r9,r10,3 c000000000094170 0x913f0028 stw r9,40(r31) c000000000094174 0xe93f002a lwa r9,40(r31) c000000000094178 0x7d234b78 mr r3,r9 c00000000009417c 0x383f0040 addi r1,r31,64 c000000000094180 0xebe1fff8 ld r31,-8(r1) c000000000094184 0x4e800020 blr c000000000094188 0x60000000 nop ... c000000000094190 0x3c4c0121 addis r2,r12,289 c000000000094194 0x38429670 addi r2,r2,-27024 c000000000094198 0x7c0802a6 mflr r0 c00000000009419c 0x60000000 nop c0000000000941a0 0xe9240100 ld r9,256(r4) c0000000000941a4 0x39400001 li r10,1 After this it looks like: 0:mon> di c000000000094168 c000000000094168 0x06000000 0x392a0003 .long 0x392a000306000000 c000000000094170 0x913f0028 stw r9,40(r31) c000000000094174 0xe93f002a lwa r9,40(r31) c000000000094178 0x7d234b78 mr r3,r9 c00000000009417c 0x383f0040 addi r1,r31,64 c000000000094180 0xebe1fff8 ld r31,-8(r1) c000000000094184 0x4e800020 blr c000000000094188 0x60000000 nop ... c000000000094190 0x3c4c0121 addis r2,r12,289 c000000000094194 0x38429570 addi r2,r2,-27280 c000000000094198 0x7c0802a6 mflr r0 c00000000009419c 0x60000000 nop c0000000000941a0 0xe9240100 ld r9,256(r4) c0000000000941a4 0x39400001 li r10,1 c0000000000941a8 0x3d02000b addis r8,r2,11 Signed-off-by: Jordan Niethe <jniethe5@gmail.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Link: https://lore.kernel.org/r/20200602052728.18227-2-jniethe5@gmail.com |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
