+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
+
+
