error generated by clang: unknown use of instruction mnemonic without a size suffix
时间: 2024-05-22 09:13:15 浏览: 13
This error message is generated by the Clang compiler when it encounters an assembly instruction that does not have a size suffix. In assembly language, a size suffix is used to indicate the size of the operand being operated on. For example, the "mov" instruction can be used to move data between registers or memory locations, but the size of the data being moved must be specified using a size suffix such as "byte", "word", "dword", or "qword".
When Clang encounters an instruction without a size suffix, it does not know how to interpret the instruction and generates an error message. To resolve this error, you will need to add a size suffix to the instruction to specify the size of the operand being operated on. The appropriate size suffix will depend on the specific instruction and the data being operated on.
