1044 | * The value is either zero or a 4-byte aligned pointer to that TB combined | |

1046 | * additional information is encoded as follows: | |
0980011b PM |
1047 | * 0, 1: the link between this TB and the next is via the specified |
1048 | * TB index (0 or 1). That is, we left the TB via (the equivalent | |
1049 | * of) "goto_tb <index>". The main loop uses this to determine | |
1050 | * how to link the TB just executed to the next. | |
1051 | * 2: we are using instruction counting code generation, and we | |
1052 | * did not start executing this TB because the instruction counter | |
819af24b | 1053 | * would hit zero midway through it. In this case the pointer |
0980011b PM |
1054 | * returned is the TB we were about to execute, and the caller must |
1055 | * arrange to execute the remaining count of instructions. | |
378df4b2 PM |
1056 | * 3: we stopped because the CPU's exit_request flag was set |
1057 | * (usually meaning that there is an interrupt that needs to be | |
819af24b SF |
1058 | * handled). The pointer returned is the TB we were about to execute |
1059 | * when we noticed the pending exit request. | |
0980011b PM |
1060 | * |
1061 | * If the bottom two bits indicate an exit-via-index then the CPU | |
1062 | * state is correctly synchronised and ready for execution of the next | |
1063 | * TB (and in particular the guest PC is the address to execute next). | |
1064 | * Otherwise, we gave up on execution of this TB before it started, and | |
fee068e4 | 1065 | * the caller must fix up the CPU state by calling the CPU's |
819af24b | 1066 | * synchronize_from_tb() method with the TB pointer we return (falling |
fee068e4 PC |
1067 | * back to calling the CPU's set_pc method with tb->pb if no |
1068 | * synchronize_from_tb() method exists). | |
0980011b PM |
