- callback_suite_aggrs: enabling (non-standard) struct packing, by default (via #pragma, should be ignored by compilers not handling that) - comment fix

-- user config for rand-sig.lua:

maxaggrfields= 12
maxarraylen  = 16   -- see *)

-- *) note some callconvs pass structs via regs, so using big numbers here will
--    reduce those cases; however special alignment rules are specified in some
--    ABIs for bigger arrays, which is also worth testing



-- Notes: specify types more than once to increase relative occurance, e.g.:

-- this favors non-aggregate args, especially ints (and also increases avg num of aggregate fields):
--types       = "Bccssiiiiijjllpfd{}"

-- this heavily favors nested structs, while not having any union:
--types       = "Bcsijlpfd{{{{{{}"

-- this heavily favors flat and short/empty aggregates:
--types       = "Bcsijlpfd{}}}}}}<>>>>>"



-- user config for mk-cases.lua

-- force aggregate packing, 0=off, pos values set fixed packing, neg values
-- set a random power-of-2 packing per aggregate, within [1,abs(aggrpacking)]
