------- Comment #18 from rguenth at gcc dot gnu dot org 2006-11-28 12:38 ------- Most of the memory used is spent in the string pool:
String pool entries 68980 identifiers 68980 (100.00%) slots 131072 bytes 1012M (10M overhead) table size 1024k coll/search 0.7816 ins/search 0.2876 avg. entry 15394.37 bytes (+/- 68924.74) longest entry 2130575 if you add -g to the compilation, dwarf2out.c happily xstrdup()s most of them a few times and memory consumption goes up to 3.9GB. All the stringpool handling and it's usage by classtype_mangled_name is not very well optimized for such large strings (after all, we know the string length there for example). -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=29433
