OK for quarter.
Is this necessary for recognizing a different pattern?
Are you saying that the testcases xxx-1 and xxx-2 are duplicate

Hi,
This patch adds conditional sign/zero extension and truncation autovec
patterns by combining EXTENSION/TRUNCATION and VCOND_MASK patterns.
For quad truncation, two vncvt instructions are generated. This patch
combine the second vncvt and vmerge to form a masked vncvt, while the
first vncvt re
