85 /*----- Register values ---------------------------------------------------*/
87 /* The framework doesn't have a preconceived idea about what's in a register
88 * value: it just allocates them and accesses them through the register type
89 * functions. It doesn't even have a baked-in idea of how big a register
90 * value is: instead, it gets that via the `regsz' slot in `struct
91 * tvec_testinfo'. So, as far as the framework is concerned, it's safe to
92 * add new slots to this union, even if they make the overall union larger.
93 * This can be done by defining the preprocessor macro `TVEC_REGSLOTS' to be
94 * a `union' fragment defining any additional union members.
96 * This creates a distinction between code which does and doesn't know the
97 * size of a register value. Code which does, which typically means the test
98 * functions, benchmarking setup and teardown functions, and tightly-bound
99 * runner functions, is free to index the register vectors directly. Code
100 * which doesn't, which means the framework core itself and output formatting
101 * machinery, must use the `TVEC_REG' macro (or its more general `TVEC_GREG'
102 * companion) for indexing register vectors. (In principle, register type
103 * handlers also fit into this category, but they have no business peering
104 * into register values other than the one's they're given.)
108 /* The actual register value. This is what the type handler sees.
109 * Additional members can be added by setting `TVEC_REGSLOTS' before
110 * including this file.
112 * A register value can be /initialized/, which simply means that its
113 * contents represent a valid value according to its type -- the
114 * register can be compared, dumped, serialized, parsed into, etc.
115 * You can't do anything safely to an uninitialized register value
116 * other than initialize it.

134 * particular test group are initialized at all times[1] while that
135 * test group is being processed. (The other register slots don't
136 * even have types associated with them, so there's nothing useful we
137 * could do with them.)
139 * The `TVRF_LIVE' flag indicates that the register was assigned a
140 * value by the test vector file: it's the right thing to use to
141 * check whether an optional register is actually present. Even
142 * `dead' registers are still initialized, though.
144 * [1] This isn't quite true. Between individual tests, the
145 * registers are released and reinitialized in order to reset
146 * them to known values ready for the next test. But you won't
