Before we go ahead and fix this issue and we would like to know the

Hi Sirl,
As you mention in Bugzilla (comment 13),
aix_return( return in memory)
svr4_return(in registers)
what is the semantics of *svr4gnu* w.r.t return .

Thank you Sirl,

be the default (-msvr4-struct-return=standard)
by default, you mean using registers to return?

Hi,
As per our analysis on the issue, I have some queries as per below:
Is there any target hooks for alloca?
Should we do the same like __builtin_alloca_with_align (array
allocation) or we assume the problem as a target based
(prologue/epilogue optimization) issue?
