2018-03-07RISC-V DisassemblerMichael Clark
The RISC-V disassembler has no dependencies outside of the 'disas' directory so it can be applied independently. The majority of the disassembler is machine-generated from instruction set metadata: - https://github.com/michaeljclark/riscv-meta Expected checkpatch errors for consistency and brevity reasons: ERROR: line over 90 characters ERROR: trailing statements should be on next line ERROR: space prohibited between function name and open parenthesis '(' Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Signed-off-by: Michael Clark <mjc@sifive.com>

2017-02-07Fix Thumb-1 BE32 execution and disassembly.Julian Brown
Thumb-1 code has some issues in BE32 mode (as currently implemented). In short, since bytes are swapped within words at load time for BE32 executables, this also swaps pairs of adjacent Thumb-1 instructions. This patch un-swaps those pairs of instructions again, both for execution, and for disassembly. (The previous version of the patch always read four bytes in arm_read_memory_func and then extracted the proper two bytes, in a probably misguided attempt to match the behaviour of actual hardware as described by e.g. the ARM9TDMI TRM, section 3.3 "Endian effects for instruction fetches". It's less complicated to just read the correct two bytes though.)

2012-07-14disas: Fix printing of addresses in disassemblyPeter Maydell
In our disassembly code, the bfd_vma type is always 64 bits, even if the target's virtual address width is only 32 bits. This means that when we print out addresses we need to truncate them to 32 bits, to avoid odd output which has incorrectly sign-extended a value to 64 bits, for instance this ARM example: 0x80479a60: e59f4088 ldr r4, [pc, #136] ; 0xffffffff80479a4f (It would also be possible to truncate before passing the address to info->print_address_func(), but truncating in the final print function is the same approach that binutils takes to this problem.)

2012-03-14Rename CPUState -> CPUArchStateAndreas Färber
Scripted conversion: for file in *.[hc] hw/*.[hc] hw/kvm/*.[hc] linux-user/*.[hc] linux-user/m68k/*.[hc] bsd-user/*.[hc] darwin-user/*.[hc] tcg/*/*.[hc] target-*/cpu.h; do sed -i "s/CPUState/CPUArchState/g" $file done All occurrences of CPUArchState are expected to be replaced by QOM CPUState, once all targets are QOM'ified and common fields have been extracted.
