--- Comment #10 from Nelson Chu <nelsonc1225 at sourceware dot org> ---
Sorry, I must want to check something while development, but forgot to chan=
ge
the behavior back to what it was...

Before the fixed patch, I can also get the unexpected behavior,

nelson@LAPTOP-QFSGI1F2:~$
~/binutils-dev/build-gdb/build-install/bin/riscv64-unknown-elf-gdb
...
(gdb) disassemble 0x0,+4
Dump of assembler code from 0x0 to 0x4:
   0x0000000000000000:
   0x0000000000000001:
   0x0000000000000002:
   0x0000000000000003:
End of assembler dump.

After the fixed patch, I should get the expected result,

nelson@LAPTOP-QFSGI1F2:~$
~/binutils-dev/build-gdb/build-install/bin/riscv64-unknown-elf-gdb
...
(gdb) disassemble 0x0,+4
Dump of assembler code from 0x0 to 0x4:
   0x0000000000000000:  Cannot access memory at address 0x0


I am not sure how to run the entire gdb regressions...  Tom, could you help=
 to
check if the testcases pass for now?  Sorry for accidentally breaking these.
