Peter Maydell 9e024732f5 linux-user: provide frame information in x86-64 safe_syscall ... Use cfi directives in the x86-64 safe_syscall to allow gdb to get backtraces right from within it. (In particular this will be quite a common situation if the user interrupts QEMU while it's in a blocked safe-syscall: at the point of the syscall insn RBP is in use for something else, and so gdb can't find the frame then without assistance.)
