This PR adds support for Qualcomm Oryon arm64 chips, AKA Snapdragon X1, that are used in various laptops like the Thinkpad T14s.
With this patch, the
counters-testtest succeeds for me and most of the main tests also pass on my machine (with a Snapdragon X1E-78-100). 5 tests do fail which I looked into:tls: these 2 seem to be related to an existing gdb bug (./gdb/regcache.c:810: internal-error: cooked_read: Assertion `regnum >= 0 && regnum < m_descr->nr_cooked_registers' failed.)fork_exec_info_thris backtrace related (Backtrace stopped: Cannot access memory at address 0x681ffc10)record_replay: these 2 may be related to pointer authentication (SIGILL due to ptrace withPTRACE_SETREGSETofNT_ARM_PACA_KEYS)In any case I don't think they're caused by this patch itself.
