1121 | AARCH64_OPDE_RECOVERABLE | |
1122 | Less severe error found during the parsing, very possibly because that | |
1123 | GAS has picked up a wrong instruction template for the parsing. | |
1124 | ||
1125 | AARCH64_OPDE_SYNTAX_ERROR | |
1126 | General syntax error; it can be either a user error, or simply because | |
1127 | that GAS is trying a wrong instruction template. | |
1128 | ||
1129 | AARCH64_OPDE_FATAL_SYNTAX_ERROR | |
1130 | Definitely a user syntax error. | |
1131 | ||
1132 | AARCH64_OPDE_INVALID_VARIANT | |
1133 | No syntax error, but the operands are not a valid combination, e.g. | |
1134 | FMOV D0,S0 | |
1135 | ||
0c608d6b RS |
1136 | AARCH64_OPDE_UNTIED_OPERAND |
1137 | The asm failed to use the same register for a destination operand | |
1138 | and a tied source operand. | |
1139 | ||
a06ea964 NC |
1140 | AARCH64_OPDE_OUT_OF_RANGE |
1141 | Error about some immediate value out of a valid range. | |
1142 | ||
1143 | AARCH64_OPDE_UNALIGNED | |
1144 | Error about some immediate value not properly aligned (i.e. not being a | |
1145 | multiple times of a certain value). | |
1146 | ||
1147 | AARCH64_OPDE_REG_LIST | |
1148 | Error about the register list operand having unexpected number of | |
1149 | registers. | |
1150 | ||
1151 | AARCH64_OPDE_OTHER_ERROR | |
1152 | Error of the highest severity and used for any severe issue that does not | |
1153 | fall into any of the above categories. | |
1154 | ||
1155 | The enumerators are only interesting to GAS. They are declared here (in | |
1156 | libopcodes) because that some errors are detected (and then notified to GAS) | |
1157 | by libopcodes (rather than by GAS solely). | |
1158 | ||
1159 | The first three errors are only deteced by GAS while the | |
1160 | AARCH64_OPDE_INVALID_VARIANT error can only be spotted by libopcodes as | |
1161 | only libopcodes has the information about the valid variants of each | |
1162 | instruction. | |
1163 | ||
1164 | The enumerators have an increasing severity. This is helpful when there are | |
1165 | multiple instruction templates available for a given mnemonic name (e.g. | |
1166 | FMOV); this mechanism will help choose the most suitable template from which | |
1167 | the generated diagnostics can most closely describe the issues, if any. */ | |
