qemu sparc -cpu help does not generate correct display

[Donald R Laster Jr]

The output for the "-cpu help" on the Sparc executables is not generating accurate information.

Running

./qemu-sparc64 -cpu help

produces:

The T1 entries are in the list above. The Micro- and Super- SPARC
entries are not supposed to be there because they are 32 bit CPUs and
thus not compatible with qemu-sparc64.
Works as designed.
