Subject: Workaround 'unused variable' cppcheck style warnings
X-Git-Tag: v8.0.0~1109
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=5aaa3cc6f9aa5b2f0956f5be55e2143605ab7026;p=platform%2Fupstream%2Flibgc.git

Workaround 'unused variable' cppcheck style warnings

* include/private/gc_locks.h [PCR && THREADS] (DCL_LOCK_STATE): Define
to empty if CPPCHECK.
* mach_dep.c [MACOS && __MWERKS__ && POWERPC] (getRegisters): Declare
as external of CPPCHECK (as cppcheck does not recognize "asm" in
function declaration).
