Only RV64GC is supported. RISC-V Fuchsia is not able to serve packages yet so unit testing is not possible. Bug: fuchsia:127655 Tested: `crasher` with crashpad added to crashsvc, ran minidump through Breakpad stackwalker Change-Id: I1b6d79128759281aee348e333ea15434ab397001 Reviewed-on: https://chromium-review.googlesource.com/c/crashpad/crashpad/+/4602412 Reviewed-by: Mark Mentovai <mark@chromium.org> Reviewed-by: Joshua Peraza <jperaza@chromium.org>
