In issue11656.go, it tests that if the runtime can get a reasonable traceback when it faults at a non-function PC. It does it by jumping to an address that contains an illegal or trap instruction. When it traps, the SIGTRAP crashes the runtime. This CL changes it to use an instruction that triggers SIGSEGV. This is due to two reasons: - currently, the handling of bad PC is done by preparePanic, which is only used for a panicking signal (SIGSEGV, SIGBUS, SIGFPE), not a fatal signal (e.g. SIGTRAP). - the test uses defer+recover to get a traceback, which only works for panicking signals, not fatal signals. Ideally, we should handle all kinds of faults (SIGSEGV, SIGBUS, SIGILL, SIGTRAP, etc.) with a nice traceback. I'll leave this for the future. This CL also adds RISCV64 support. Fixes #43283.

README.md
The test directory contains tests of the Go tool chain and runtime. It includes black box tests, regression tests, and error output tests. They are run as part of all.bash.
To run just these tests, execute:
../bin/go run run.go
To run just tests from specified files in this directory, execute:
../bin/go run run.go -- file1.go file2.go ...
Standard library tests should be written as regular Go tests in the appropriate package.
The tool chain and runtime also have regular Go tests in their packages. The main reasons to add a new test to this directory are:
- it is most naturally expressed using the test runner; or
- it is also applicable to
gccgoand other Go tool chains.
