| 132 | |
| 133 | An origin tag comprises an upper 30-bit ECU field and a lower 2-bit |
| 134 | 'kind' field. The ECU field is a number given out by m_execontext |
| 135 | and has a 1-1 mapping with ExeContext*s. An ECU can be used |
| 136 | directly as an origin tag (otag), but in fact we want to put |

| 138 | tag came from. This helps print more understandable error messages |
| 139 | for the user -- it has no other purpose. |
| 140 | |
| 141 | Hence the following 2-bit constants are needed for 'kind' field. |
| 142 | |
| 143 | To summarise: |
| 144 | |
| 145 | * Both ECUs and origin tags are represented as 32-bit words |
| 146 | |
| 147 | * m_execontext and the core-tool interface deal purely in ECUs. |
| 148 | They have no knowledge of origin tags - that is a purely |
| 149 | Memcheck-internal matter. |
| 150 | |
| 151 | * all valid ECUs have the lowest 2 bits zero and at least |
| 152 | one of the upper 30 bits nonzero (see VG_(is_plausible_ECU)) |
| 153 | |
| 154 | * to convert from an ECU to an otag, OR in one of the MC_OKIND_ |
| 155 | constants below |
| 156 | |
| 157 | * to convert an otag back to an ECU, AND it with ~3 |
