lto.c (lto_wpa_write_files): Move call to lto_promote_cross_file_statics ...
2014-03-19 Richard Biener <rguenther@suse.de>
* lto.c (lto_wpa_write_files): Move call to
lto_promote_cross_file_statics ...
(do_whole_program_analysis): ... here, into the partitioning
block. Do not ggc_collect after lto_wpa_write_files but
for a last time before it.
