Using qemu (user mode) with gdb testsuites

[Meg Yuan]

Hi there,

I'm wondering if it is possible to use qemu as gdbserver when running gdb
testsuites from a riscv cross-compiler with dejagnu.

Here is an example of starting qemu (user mode) with the program at
localhost:1234:

qemu-riscv64 -g 1234 <program>

Then, we can start gdb with connection to qemu with this command:

riscv64-unknown-linux-gnu-gdb <program> -ex "target remote localhost:1234"

I am new to dejagnu. Though I tried some existing recipes, none worked out
of the box. Has anyone done this before? If so, could you give me a recipe
for an exp file?

Thanks,
Meg
