I  just added -gsystem-verilog flag to the driver in my local copy( easy   task as Steve mentioned).While going through the   lexor_keyword.gpref..., I saw two   keywords GN_KEYWORDS_ICARUS and ..1364_2005.Which one is advisable for adding sv keywords " logic" seems to be already there with -gxtypes

Neither. I'd create a new keyword category GN_KEYWORDS_1800_2005.
SystemVerilog is IEEE 1800 and you are probably working off the -2005
version. The compiler.h header file defines the keywork catagory mask
bits. The definition has comments that describe what the mask is
about, so you should see that you can select a bit and define your
new GN_KEYWORDS_* to use that bit. Then when you add your keywords
to the lexor_keywords.gperf file, use your bit.

SystemVerilog support is a *big* task. You'll be at it for a while;-)
If you haven't already done so, make sure you've read through and
understood the Developer Guide on the iverilog.wikia.com documentation
wiki.
