H A Dcpu.c65c1c039cdbcf66e9bc5b0366c8f7cc22284359a Tue Nov 05 10:09:55 UTC 2024 Peter Maydell <peter.maydell@linaro.org> target/sparc: Move cpu_put_fsr(env, 0) call to reset

Currently we call cpu_put_fsr(0) in sparc_cpu_realizefn(), which
initializes various fields in the CPU struct:
* fsr_cexc_ftt
* fcc[]
* fsr_qne
* fsr
It also sets the rounding mode in env->fp_status.

This is largely pointless, because when we later reset the CPU
this will zero out all the fields up until the "end_reset_fields"
label, which includes all of these (but not fp_status!)

Move the cpu_put_fsr(env, 0) call to reset, because that expresses
the logical requirement: we want to reset FSR to 0 on every reset.
This isn't a behaviour change because the fields are all zero anyway.
