#
# outs: if a node defines more than one output, the names of the projections
# nodes having outs having automatically the mode mode_T
+# One can also annotate some flags for each out, additional to irn_flags.
+# They are separated from name with a colon ':', and concatenated by pipe '|'
+# Only I and S are available at the moment (same meaning as in irn_flags).
+# example: [ "frame:I", "stack:I|S", "M" ]
#
# comment: OPTIONAL comment for the node constructor
#
# 1 - caller save (register must be saved by the caller of a function)
# 2 - callee save (register must be saved by the called function)
# 4 - ignore (do not assign this register)
+# 8 - emitter can choose an arbitrary register of this class
+# 16 - the register is a virtual one
# NOTE: Last entry of each class is the largest Firm-Mode a register can hold
