示例1: assert
uint32_t
StructuredLoopToSelectionReductionOpportunity::FindOrCreateFunctionVariable(
uint32_t pointer_type_id) {
// The pointer type of a function variable must have Function storage class.
assert(context_->get_type_mgr()
->GetType(pointer_type_id)
->AsPointer()
->storage_class() == SpvStorageClassFunction);
// Go through the instructions in the function's first block until we find a
// suitable variable, or go past all the variables.
BasicBlock::iterator iter = enclosing_function_->begin()->begin();
for (;; ++iter) {
// We will either find a suitable variable, or find a non-variable
// instruction; we won't exhaust all instructions.
assert(iter != enclosing_function_->begin()->end());
if (iter->opcode() != SpvOpVariable) {
// If we see a non-variable, we have gone through all the variables.
break;
}
if (iter->type_id() == pointer_type_id) {
return iter->result_id();
}
}
// At this point, iter refers to the first non-function instruction of the
// function's entry block.
const uint32_t variable_id = context_->TakeNextId();
std::unique_ptr<Instruction> variable_inst(new Instruction(
context_, SpvOpVariable, pointer_type_id, variable_id,
{{SPV_OPERAND_TYPE_STORAGE_CLASS, {SpvStorageClassFunction}}}));
iter->InsertBefore(std::move(variable_inst));
return variable_id;
