<pre>Relocatable expressions may be used as operands; however they are not accounted
for when computing the total number of literals used by an instruction.
Examples:
// All GPUs
s_sub_u32 s0, 123, 123 // ok
s_sub_u32 s0, 123, 456 // error
s_sub_u32 s0, 123, x // ok, but should trigger an error
// GFX10
v_bfe_u32 v0, v1, 123, 123 // ok
v_bfe_u32 v0, v1, 123, 456 // error
v_bfe_u32 v0, v1, 123, x // ok, but should trigger an error
// GFX9
v_bfe_u32 v0, v2, v3, v4 // ok
v_bfe_u32 v0, v2, v3, 123 // error
v_bfe_u32 v0, v2, v3, x // breaks assembler (should trigger an error)</pre>
