Emulation of a math function fails for m68k Linux user mode
Please check the attached math-example.c file.
When running the m68k executable under QEMU, it results in an "Illegal instruction" error.
Other targets don't produce this error.
Steps to reproduce the bug:
1. Download the math-example.c attached file.
2. Compile it by running:
m68k-linux-gnu-gcc -O2 -static math-example.c -o math-example-m68k -lm
3. Run the executable with QEMU:
/build/qemu-5.0.0/build-gcc/m68k-linux-user/qemu-m68k math-example-m68k
The output of execution is:
Profiling function expm1f():
qemu: uncaught target signal 4 (Illegal instruction) - core dumped
Illegal instruction (core dumped)
Expected output:
Profiling function expm1f():
Elapsed time: 47 ms
Control result: 71804.953125
