[Bug gas/5662] New: Maverick Crunch instructions not recognised with -mfpu=maverick; -mcpu=ep9312 about to be deprecated

[martinwguy at yahoo dot it]

To emit instructions for the Cirrus Logic Maverick Crunch FPU, at present
-mcpu=ep9312 -mfpu=maverick are both necessary; gcc is happy to emit Crunch
instructions with just -mcpu=arm920t -mfpu=maverick but gas barfs saying:

/tmp/ccTa9oWw.s:31: Error: selected processor does not support `cfldrd 
mvd1,[r3,#0]'
/tmp/ccTa9oWw.s:33: Error: selected processor does not support `cfldrd 
mvd0,[r3,#0]'
/tmp/ccTa9oWw.s:34: Error: selected processor does not support `cfmuld
mvd0,mvd1,mvd0'
/tmp/ccTa9oWw.s:36: Error: selected processor does not support `cfmvrdl r2,mvd0'
/tmp/ccTa9oWw.s:37: Error: selected processor does not support `cfmvrdh r3,mvd0'

Now the ep9312 alias is about to be deprecated in gcc-4.3 and removed in
gcc-4.4, which will make compiling for Crunch impossible. The most obvious fix
is to make gas enable Maverick Crunch instructions in gas when -mfpu=maverick is
specified.
