[Patch, fortran] PR35780 - internal compiler error for complicated PARAMETER expressions

[Paul Richard Thomas]

:ADDPATCH fortran:

I dropped working on WHERE PRs to do this because it was originally
posted as a regression.  In fact I do not think that it was but I have
fixed it anyway:)

This is a simple extension of expr.c(scalarize_intrinsic_call) to use
any of the arguments of an elemental intrinsic function as the
template to build up the array of function calls.  When I wrote this
function, I had not thought through the possibility that multiple
argument elementals might need scalarization.  The patch speaks for
itself and the testcase is essentially the reporter's.

Bootstrapped and regtested on x86_ia64/FC8 - OK for trunk and 4.3?
