If the field/value isn't used yet, wouldn't it make sense to change the texts so that they use an underscore instead of space? I believe that it makes life easier for everyone and helps to avoid similar questions in the future. It seems that GCC uses just v7/v8/v9 (without "SPARC") so that the space doesn't seem to come from an attempt for alignment with GCC or something like that. Regarding Marks attempt - if I understand it correctly (based on information in Wikipedia ;-) ), Sparc v7 supports no HW multiplication / division. So a simple check may be to write a one liner containing multiplication, compiling it with any ppcsparc (or ppccrosssparc) while using the -s parameter and then checking the generated assembly for use of the mul/div asm instructions...
