+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
+
+
+
+
+
+Tracing gives me:
+
+IN: expm1f
+0x800005cc:  fetoxm1x %fp2,%fp0
+Disassembler disagrees with translator over instruction decoding
+Please report this to <email address hidden>
+
+(gdb) x/2hx 0x800005cc
+0x800005cc:	0xf200	0x0808
+
+The instruction is not implemented in qemu. I fix that.
+
+
+
+Fix available.
+
+Execution doesn't fail anymore:
+
+  Profiling function expm1f():
+    Elapsed time: 41 ms
+    Control result: 71805.108342
+
+Control result matches real hardware one:
+
+  Profiling function expm1f():
+    Elapsed time: 2152 ms
+    Control result: 71805.108342
+
+
