Subject: [PATCH 00/10] simplify and canonicalize signed compares
Date: Tue, 26 Jan 2021 23:04:22 +0100	[thread overview]
Message-ID: <20210126220432.58265-1-luc.vanoostenryck@gmail.com> (raw)

This series fixes and improves the simplification and the
canonicalization of signed compares.

Luc Van Oostenryck (10):
  cmps: make clearer we're using the operands' size
  cmps: fix simplification of sext(x) + signed compare of {SMAX,SMIN}
  cmpu: fix canonicalization of unsigned (x {<,>=} C) --> (x {<=,>} C-1)
  cmps: add testcases for simplification of signed compares
  cmps: simplify signed compares with SMIN or SMAX
  cmps: canonicalize signed compares with SMIN/SMAX
  cmps: canonicalize SMIN/SMAX +- 1 --> EQ/NE
  cmps: canonicalize signed compares with constant
  cmps: canonicalize SEL(x {<,<=} y, a, b) --> SEL(x {>=,>} y, b, a)
  cmps: canonicalize SEL(x > 0, a, -a) --> SEL(x >= 0, a, -a)
