tstSSM.cpp@ 100696

Last change on this file since 100696 was 99775, checked in by vboxsync, 19 months ago
*: Mark functions as static if not used outside of a given compilation unit. Enables the compiler to optimize inlining, reduces the symbol tables, exposes unused functions and in some rare cases exposes mismtaches between function declarations and definitions, but most importantly reduces the number of parfait reports for the extern-function-no-forward-declaration category. This should not result in any functional changes, bugref:3409
