Subject: [PATCH 0/4] simplification of computed goto
Date: Sat, 21 Nov 2020 21:52:56 +0100 [thread overview]
Message-ID: <20201121205300.94642-1-luc.vanoostenryck@gmail.com> (raw)
This series contains some simplification of computed gotos with
1 or 2 possible target as well as a new instruction which now
really allows the CSE of 'labels-as-values'.
Luc Van Oostenryck (4):
add testcases for COMPUTEDGOTO simplification
simplify OP_COMPUTEDGOTO with unique and known target
simplify CGOTO(SEL(x, L1, L2)) into CBR x, L1, L2
add a new instruction for label-as-value
