// TODO(greg-lunarg): Add tests to verify handling of these cases:
//
// Empty modules
// Modules without function definitions
// Modules in which all functions do not call other functions
// Caller and callee both accessing the same global variable
// Functions with OpLine & OpNoLine
// Others?
// TODO(dneto): Test suggestions from code review
// https://github.com/KhronosGroup/SPIRV-Tools/pull/534
//
// Callee function returns a value generated outside the callee,
// e.g. a constant value. This might exercise some logic not yet
// exercised by the current tests: the false branch in the "if"
// inside the spv::Op::OpReturnValue case in InlinePass::GenInlineCode?
// SampledImage before function call, but callee is only single block.
// Then the SampledImage instruction is not cloned. Documents existing
// behaviour.
// SampledImage after function call. It is not cloned or changed.
