示例1: consume_yields
# 需要导入模块: from pykit.ir import Builder [as 别名]
# 或者: from pykit.ir.Builder import replace_predecessor [as 别名]
def consume_yields(func, consumer, generator_func, valuemap):
b = Builder(func)
copier = lambda x : x
loop = consumer.loop
inlined_values = set(valuemap.values())
for block in func.blocks:
if block in inlined_values:
for op in block.ops:
if op.opcode == 'yield':
# -- Replace 'yield' by the loop body -- #
b.position_after(op)

# Copy blocks
blocks = [copier(block) for block in loop.blocks]
# Insert blocks
prev = op.block
for block in blocks:
func.add_block(block, after=prev)
prev = block
# Fix wiring
b.jump(blocks[0])
b.position_at_end(blocks[-1])
b.jump(resume)
# We just introduced a bunch of copied blocks
func.reset_uses()
# Update phis with new predecessor
b.replace_predecessor(loop.tail, op.block, loop.head)
b.replace_predecessor(loop.tail, op.block, loop.head)
# Replace next() by value produced by yield
value = op.args[0]
consumer.next.replace_uses(value)
op.delete()
# We don't need these anymore
consumer.next.delete()
