From f046f4c87acd6605fd0186b806717059c6657133 Mon Sep 17 00:00:00 2001 From: Wilfried Moser Date: Wed, 10 Apr 1996 10:01:30 +0000 Subject: * ch-valprint.c (chill_val_print): Remove call to calculate_array_length. (calculate_array_length): Move function from here ... * ch-exp.c (calculate_array_length): ... to here.
