view test/call_suite_aggrs/config.lua @ 519:99819b874bac

test/call_suite_aggrs: - refactored generator code a bit to be simpler, write cleaner output, have better shareability and clarity - added rtypes w/ default value nil to config.lua, to self document - shared some code under test/common/ - fixed nonemptyaggrs sigs and cases.h (accidentally overwritten with cases having empty aggrs)

-- *) 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{}}}}}}<>>>>>"
