Subject: [PATCH 00/16] simplify & canonicalize compares
Date: Sun,  8 Nov 2020 02:19:30 +0100	[thread overview]
Message-ID: <20201108011939.94252-1-luc.vanoostenryck@gmail.com> (raw)

This series contains a series of simplifications and
canonicalizations, mainly ones involving sign or zero extension.

Luc Van Oostenryck (16):
  cmp: adapt testcase for compares' canonicalization
  cmp: add testcases for the simplification of compares
  cmp: add signed/unsigned to opcode table
  cmp: move some code in a separate function: simplify_compare_constant()
  cmp: use a few helpers for the simplification of compares
  cmp: canonicalize unsigned (x {<,>=} C) --> (x {<=,>} C-1)
  cmp: simplify unsigned (x {<=,>} UMAX) into {1,0}
  cmp: canonicalize unsigned compare with UMAX or UMAX-1
  cmp: canonicalize unsigned (x {<=,>} SMAX)
  cmp: simplify sext(x) cmp C --> x cmp C
  cmp: simplify zext(x) cmp C --> x cmp C
  cmp: simplify sext(x) cmps {SMAX,SMIN}
  cmp: canonicalize sext(x) cmpu C (with C >= SMAX)
  cmp: simplify zext(x) cmps C
  cmp: simplify zext(x) cmpu C
  cmp: simplify compares and sign/zero extend
