Added: trunk/payloads/libpayload/bin/ trunk/payloads/libpayload/bin/lp.functions trunk/payloads/libpayload/bin/lpas trunk/payloads/libpayload/bin/lpgcc trunk/payloads/libpayload/lib/ trunk/payloads/libpayload/lib/libpayload.ldscript Removed: trunk/payloads/libpayload/libpayload.ldscript Modified: trunk/payloads/libpayload/Makefile trunk/payloads/libpayload/sample/Makefile Log: libpayload: Implement gcc wrappers for libpayload
