llvm.getelementptr is an instruction to do pointer arithmetic by adding/subtracting offsets from a pointer.

See external documentation.

GetElementPtr is documented in various places online:

See the LLVM documentation. A good blogpost.

Note that the first two discuss LLVM IRs GEP operation, not the MLIR one. The semantics are the same, but the structure used by MLIR is not well documented (yet) and the syntax is a bit different.

Here we focus on MLIRs GEP operation:

%res = llvm.getelementptr %ptr [1, 2, %val] ^^^^ ^^^^^^^^^^ input indices

The central point to understanding GEP is that:

GEP never dereferences, it only does math on the given pointer

It always returns a pointer to the element "selected" that is some number of bytes offset from the input pointer:

result = ptr + x for some x parametrized by the arguments

Examples:

Given the following pointer:

%ptr : llvm.ptr<llvm.struct<(i32, i32, llvm.array<2xi32>)>>

The following indices point to the following things:

[0] -> The first element of the pointer, so a pointer to the struct: llvm.ptr<llvm.struct<(i32, i32, llvm.array<2xi32>)>>

[1] -> The next element of the pointer, useful if the pointer points to a list of structs. Equivalent to (ptr + 1), so points to llvm.ptr<llvm.struct<(i32, i32, llvm.array<2xi32>)>>

[0,0] -> The first member of the first struct: llvm.ptr

[1,0] -> The first member of the second struct pointed to by ptr (can result in out-of-bounds access if the ptr only points to a single struct) llvm.ptr

[0,2] -> The third member of the first struct. llvm.ptr<llvm.array<2,i32>>

[0,2,0] -> The first entry of the array that is the third member of the first struct pointed to by our ptr. llvm.ptr

[0,0,1] -> Invalid! The first element of the first struct has no "sub-elements"!

Here is an example of invalid GEP operation parameters:

Given a different pointer to the example above:

%ptr : llvm.ptr<llvm.struct<(llvm.ptr, i32)>>

Note the two pointers, one to the struct, one in the struct.

We can do math on the first pointer:

[0] -> First struct llvm.ptr<llvm.struct<(llvm.ptr, i32)>>

[0,1] -> Second member of first struct llvm.ptr

[0,0] -> First member of the first struct llvm.ptr>

[0,0,3] -> Invalid! In order to find the fourth element in the pointer it would need to be dereferenced! GEP can't do that!

Expressed in "C", this would equate to:

address of first struct

(ptr + 0)

address of first field of first struct

&((ptr + 0)->elm0) ^^^^^^ Even though it looks like it, we are not actually dereferencing ptr here.

address of fourth element:

&(((ptr + 0)->elm0 + 3)) ^^^^^^^^^^ This actually dereferences (ptr + 0) to access elm0!

Which translates to roughly this MLIR code:

%elm0_addr = llvm.gep %ptr[0,0] : (!llvm.ptr<...>) -> !llvm.ptr<!llvm.ptr> %elm0 = llvm.load %elm0_addr : (!llvm.ptr>) -> !llvm.ptr %elm0_3_addr = llvm.gep %elm0[3] : !llvm.ptr -> !llvm.ptr

Here the necessary dereferencing is very visible, as %elm0_3_addr is only accessible through an llvm.load on %elm0_addr.

                              input   indices

    The central point to understanding GEP is that:
    > GEP never dereferences, it only does math on the given pointer

    It *always* returns a pointer to the element "selected" that is some
    number of bytes offset from the input pointer:

    `result = ptr + x` for some x parametrized by the arguments

    ## Examples:

    Given the following pointer:

    %ptr : llvm.ptr<llvm.struct<(i32, i32, llvm.array<2xi32>)>>

    The following indices point to the following things:

    [0]      -> The first element of the pointer, so a pointer to the struct:
                llvm.ptr<llvm.struct<(i32, i32, llvm.array<2xi32>)>>

    [1]      -> The *next* element of the pointer, useful if the
                pointer points to a list of structs.
                Equivalent to (ptr + 1), so points to
                llvm.ptr<llvm.struct<(i32, i32, llvm.array<2xi32>)>>

    [0,0]    -> The first member of the first struct:
                llvm.ptr<i32>

    [1,0]    -> The first member of the *second* struct pointed to by ptr
                (can result in out-of-bounds access if the ptr only points to a single struct)
                llvm.ptr<i32>

    [0,2]    -> The third member of the first struct.
                llvm.ptr<llvm.array<2,i32>>

    [0,2,0]  -> The first entry of the array that is the third member of
                the first struct pointed to by our ptr.
                llvm.ptr<i32>

    [0,0,1]  -> Invalid! The first element of the first struct has no "sub-elements"!


    Here is an example of invalid GEP operation parameters:

    Given a different pointer to the example above:

    %ptr : llvm.ptr<llvm.struct<(llvm.ptr<i32>, i32)>>

    Note the two pointers, one to the struct, one in the struct.

    We can do math on the first pointer:

    [0]      -> First struct
                llvm.ptr<llvm.struct<(llvm.ptr<i32>, i32)>>

    [0,1]    -> Second member of first struct
                llvm.ptr<i32>

    [0,0]    -> First member of the first struct
                llvm.ptr<llvm.ptr<i32>>

    [0,0,3]  -> Invalid! In order to find the fourth element in the pointer
                it would need to be dereferenced! GEP can't do that!

    Expressed in "C", this would equate to:

    # address of first struct
    (ptr + 0)

    # address of first field of first struct
    &((ptr + 0)->elm0)
               ^^^^^^
               Even though it looks like it, we are not actually
               dereferencing ptr here.

    # address of fourth element:
    &(((ptr + 0)->elm0 + 3))
                ^^^^^^^^^^
                This actually dereferences (ptr + 0) to access elm0!

    Which translates to roughly this MLIR code:

    %elm0_addr   = llvm.gep %ptr[0,0]   : (!llvm.ptr<...>) -> !llvm.ptr<!llvm.ptr<i32>>
    %elm0        = llvm.load %elm0_addr : (!llvm.ptr<llvm.ptr<i32>>) -> !llvm.ptr<i32>
    %elm0_3_addr = llvm.gep %elm0[3]    : !llvm.ptr<i32> -> !llvm.ptr<i32>

    Here the necessary dereferencing is very visible, as %elm0_3_addr is only
    accessible through an `llvm.load` on %elm0_addr.
