[CMake] Anybody using IAR compiler here ?

[Alexander Neundorf]

Hi,

is anybody here using an IAR compiler for AVR or ARM ?
If so, how can I execute the assembler so that it just prints its name and 
version number and exits ?
(i.e. the equivalent to "as --version", which gives
"GNU assembler (Linux/GNU Binutils) 2.17.50.0.17.20070615

...")

Thanks
Alex
