[Csnd] tables of arbitrary size

Subject	[Csnd] tables of arbitrary size
	the manual page for f statements has the following note: "Not all opcodes accept tables whose size is not a power of two, since they may depend on this for internal optimization." with respect to this i have two questions: - is there a list of all the opcodes that accept tables of arbitrary size? - would it be too difficult or for some reason inconvenient that all the opcodes that normally access tables created with GEN01 could read tables of deferred size? (hint: fog) best, lj

	Hi Luis, The thing is that there are some significant performance optimizations in the code that are only possible for table sizes that are powers of two (they are actually quite significant, and still relevant for mobile platforms). What could be done is write an opcode that does take arbitrary sized tables. I don't think there is actually a list, but it would be ideal if each opcode had information about this. You can check in the sources where it will be clear when the opcode accesses the f-table, whether it requires a power of two or not.
