Subject: [PATCH v2 00/11] aarch64: Implement TImode comparisons
Date: Thu,  2 Apr 2020 11:53:42 -0700	[thread overview]
Message-ID: <20200402185353.11047-1-richard.henderson@linaro.org> (raw)

This is attacking case 3 of PR 94174.

In v2, I unify the various subtract-with-borrow and add-with-carry
patterns that also output flags with unspecs.  As suggested by
Richard Sandiford during review of v1.  It does seem cleaner.
