Re: 971122 for arm-coff dies building newlib/libm: testcase attached

[Richard Earnshaw <rearnsha at arm dot com>]

This patch was checked into the gcc2 sources back in October to fix 
precisely this bug.  There are a large number of ARM related patches that 
have been made to the gcc2 tree that have not yet propagated to egcs (ie 
most of them).  I thought there were going to be regular merges of gcc2 
changes into the egcs tree?

        * arm.md (movsfcc): If not TARGET_HARD_FLOAT, ensure operand[3] 
valid.
