  "message": "parlib: Fix dlopen() with -rdynamic\n\nPart 3 of trying to fix shared objects, following up on commit c77d5ade84b7\n(\"parlib: Fix fake parlib detection for dlopen() (XCC)\").\n\nIf we use -rdynamic, all symbols from the binary (e.g. hello.c) will\noverride functions in the .so.  For instance, __in_fake_parlib() and\nvcore_lib_init() will be from the binary, not the .so, even when we\u0027re\nrunning the library\u0027s ctors.\n\nThe fix is relatively simple: __in_fake_parlib() is a static inline, which\nwon\u0027t give the opportunity for the .so to link against a global version,\nsince there is no global version.\n\nFor the ctors, we actually could leave vcore_lib_init() as a global ctor,\nsince it can safely be called multiple times.  But that\u0027s a little sloppy\nand confusing - I wondered for a little while why vcore_lib_init() ran from\nhello, while uthread_lib_init() was run from within the .so.  static vs\nglobal.  We still need the guts vcore_lib_init() to be in a header for\nuthread.c, so the sanest thing was to just split it up.\n\nSigned-off-by: Barret Rhoden \u003cbrho@cs.berkeley.edu\u003e\n",
