i64.store8
Copies the first 8 bits of an i64
value into memory at the required location.
Syntax
i64.store8 offset=n align=n
Parameters
offset Optional
A numeric value that gives an extra offset to the memory location given.
Must be a positive value.
Can be written as a decimal number or using the 0x00 hexadecimal notation.
If the memory location is 8 and you add an extra offset of 2, then the final memory location is 10.
This is useful if you are using a data structure with fields at different locations inside.
align Optional
Gives information to the machine running the application about the alignment that could be used
when setting the location of the memory. This can only be 0, 1, 2, or 4.
You will not see any difference and it may not even be used. It is more of a hint than a command.
