# Flags:
|
|
# S: has size (use in CONST1, CONST2, CONST4, CONST8 forms)
|
|
# V: has no size (use in JUMP, CJUMP, RET forms)
|
|
#
|
|
# Types:
|
|
# I, F: integer, float
|
|
# A: any (will be coerced to I or F during IR postprocessing)
|
|
#
|
|
# Any instruction with an A type must be followed by the corresponding F
|
|
# version.
