From 7d7c187b4a12f1bb350e85cdb0115e19537cc704 Mon Sep 17 00:00:00 2001 From: Simon Marlow Date: Wed, 5 Aug 2009 10:21:59 +0000 Subject: Declare RTS-private prototypes with __attribute__((visibility("hidden"))) This has no effect with static libraries, but when the RTS is in a shared library it does two things: - it prevents the function from being exposed by the shared library - internal calls to the function can use the faster non-PLT calls, because the function cannot be overriden at link time. --- rts/ThreadLabels.h | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'rts/ThreadLabels.h') diff --git a/rts/ThreadLabels.h b/rts/ThreadLabels.h index 60289ef306..550e2869e3 100644 --- a/rts/ThreadLabels.h +++ b/rts/ThreadLabels.h @@ -10,6 +10,8 @@ #ifndef THREADLABELS_H #define THREADLABELS_H +#pragma GCC visibility push(hidden) + #if defined(DEBUG) void initThreadLabelTable (void); void freeThreadLabelTable (void); @@ -19,4 +21,6 @@ void removeThreadLabel (StgWord key); void labelThread (StgPtr tso, char *label); #endif +#pragma GCC visibility pop + #endif /* THREADLABELS_H */ -- cgit v1.2.1
