i32.load
Takes 32 bits (4 bytes) of memory from the given location and pushes it onto the stack as an i32 value.

Syntax

i32.load 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.

Stack In

i32 Memory offset location to get the data from.

Stack Out

i32 The data copied from memory.

Examples

;; Memory is [ 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08 ]

;; Push the i32 memory offset value location onto the stack
i32.const 2

;; Pop the memory location off the stack, get the memory
;; at the given location, and push the value onto the stack
i32.load

;; The stack contains an i32 value of 0x06050403

;; Memory is [ 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08 ]

;; Push the i32 memory offset value location onto the stack
i32.const 2

;; Pop the memory location off the stack, get the memory
;; at the given location, and push the value onto the stack
i32.load offset=2

;; The stack contains an i32 value of 0x08070605
