Re: [PATCH for-9.2 v3 0/6] target/sparc: emulate floating point queue when raising fp traps

[Carl Hauser]

Further info: 

netbsd panics in the kernel trap handler; unfortunately it does not include the fsr in the panic message, but I expect it will be the same as on Solaris.

linux raises SIGFPE in the application that caused the exception. Not surprising since we've seen before that linux is blissfully unaware of the floating point queue.
