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
