33 // Note: We do not use C++ exceptions to avoid compiler dependencies and | |
34 // unpredictable performance. | |
35 // | |
36 // Scheme: Exceptions are stored with the thread. There is never more | |
37 // than one pending exception per thread. All functions that can throw | |
38 // an exception carry a THREAD argument (usually the last argument and | |
39 // declared with the TRAPS macro). Throwing an exception means setting | |
40 // a pending exception in the thread. Upon return from a function that | |
41 // can throw an exception, we must check if an exception is pending. | |
42 // The CHECK macros do this in a convenient way. Carrying around the | |
43 // thread provides also convenient access to it (e.g. for Handle | |
44 // creation, w/o the need for recomputation). | |
