Hello world,

this patch fixes a regression with long compile times,
which came about due to our handling of array constructors
at compile time.  This, togeteher with a simplification in
front end optimization, led to long compile times and large
code.

Regression-tested. OK for trunk and the other affected branches?


Well I know 42 is the answer to the ultimate question of the universe so this
must be OK.  I just don't know what the question is.

OK and thanks,

Jerry

+#define CONSTR_LEN_MAX 42

Actually, I was wondering about the choice myself.  With
most common hardware having fairly robust L1 and L2 cache
sizes, a double precision array constructor with 42
elements only occupies 336 bytes.  Seems small.

There is a -fmax-array-constructor=n option. Can’t we use it for the limit?
