1. "emugen" generates four *dec.cpp files containing code like this to decode offset to pointer in stream tmp = *(T *)(ptr + 8 + 4 + 4 + 4 + *(size_t *)(ptr +8 + 4 + 4)); If *dec.cpp are compiled in 64-bit, size_t is 8-byte and dereferencing of it is likley to get wild offset for dereferencing of *(T *) to crash the code. Solution is to define tsize_t for "target size_t" instead of using host size_t. 2. Cast pointer to "uintptr_t" instead of "unsigned int" for 2nd param of ShareGroup::getGlobalName(NamedObjectType, ObjectLocalName/*64bit*/). 3. Instance of EGLSurface, EGLContext and EGLImageKHR are used as 32-bit key for std::map< unsigned int, * > SurfacesHndlMap, ContextsHndlMap, and ImagesHndlMap, respectively. Cast pointer to uintptr_t and assert upper 32-bit is zero before passing to map::find(). 4. Instance of GLeglImageOES is used to eglAttachEGLImage() which expect "unsigned int". Cast it to uintptr_t and assert upper 32-bit is zero. 5. The 5th param to GLEScontext::setPointer is GLvoid* but contains 32-bit offset to vbo if bufferName exists. Cast it to uintptr_t and assert upper 32-bit is zero. 6. Use %zu instead of %d to print size_t 7. Cast pointer to (uintptr_t) in many other places Change-Id: Iba6e5bda08c43376db5b011e9d781481ee1f5a12
