riscv64 support?

[RobertBerger]

Hi, Just wanted to check what is the status with crash and riscv64.

[k-hagio]

No, the current crash does not support riscv64.

Probably the gdb-7.6 that crash contains also does not support it in the first place. We have been working on rebasing gdb to 10.1 [1], it might be needed.

Upgrading gdb is insufficient. configure.c has also to be adjusted. Please, create a branch to allow collaboration on the update.

Is there a place form where the original patch email files can be downloaded?

Here is Alexey's branch for gdb 10.2: https://github.com/YustasSwamp/crash/tree/crash-gdb10.2-devel-temp

[xypron]

For RISC-V support at least the following is needed:

• switching to current GDB
• add RISC-V defintions to configure.c (like https://github.com/xypron/crash/commit/2391175c7936a3d873b7b7f1b6c6cae2f4c166b8)
• add RISC-V definitions to defs.h
• create riscv64.c, unwind_riscv64.c

just give an update for this, there are working patches[1] for RISC-V support, which is kind of usable..
