I can reproduce this bug, but I'm not sure what QEMU is doing wrong.
Looking at the "SH4 Software Manual", it definitely says that if the
FPSCR.PR bit is 0 then the 'frchg' and 'fschg' instructions should both
trap.
The 'frchg' that autogen is hitting is the one in glibc's "getcontext" implementation:
https://sourceware.org/git/?p=glibc.git;a=blob;f=sysdeps/unix/sysv/linux/sh/sh4/getcontext.S;hb=b6d2c4475d5abc05dd009575b90556bdd3c78ad0#l70
QEMU linux-user mode runs with FPSCR=0x000800000, which is "FPSCR.PR ==
1", ie "double precision". This seems to match what the kernel has for
its FPSCR_INIT value.
Are you in a position to test what the actual hardware/real Linux kernel
using for its FPSCR value when running sh4 userspace binaries ?

I can provide access to a machine connected to the internet so you can
test it yourself. I'll send you an email.

On that hardware, at least, the user-space visible FPSCR value is indeed
0x000800000. Execution of the 'frchg' insn either doesn't trap, or the
trap is caught by the kernel and emulated. I think it is not being
emulated because CONFIG_SH_FPU_EMU is not set.
The comment at the top of arch/sh/kernel/cpu/sh4/fpu.c:
https://elixir.bootlin.com/linux/latest/source/arch/sh/kernel/cpu/sh4/fpu.c
says that on "some SH4 implementations" executing frchg with the
FPSCR.PR bit set causes a trap; the "SH-4 Software Manual" says it is
"undefined_operation()" which I think means "implementation could do
anything" (though the manual doesn't clearly define its terms here). The
kernel code in fpu.c carefully sets the FPSCR value to clear the PR bit
before performing the frchg instruction.
My best guess is that this is a glibc bug, where its getcontext etc
implementations should be doing the same set-fpscr-first work that the
kernel code is doing, and so the glibc code happens to work OK on
implementations like the SH7785 that seem to not trap here, but will
fail on whatever the SH4 variants are that do trap (as well as on QEMU).
But this needs an SH4 expert to clarify (for instance I might well have
misread the kernel code and maybe it does trap-and-emulate here so that
userspace can rely on the frchg behaviour with FPSCR.PR=1 ?).
Is there somebody we can ask for clarification on what the defined
behaviour of the architecture is here and what the impdef behaviour of
the 7750/7751/7785 happen to be ?

Bug is still pending on git master. Have not pinged the SuperH crew yet.
Will try to do that tomorrow, I'll also ping glibc upstream.
