re PR middle-end/64415 (ICE: verify_ssa failed / segmentation fault with LTO)
2015-01-14 Richard Biener <rguenther@suse.de>
PR lto/64415
* tree-inline.c (insert_debug_decl_map): Check destination
function MAY_HAVE_DEBUG_STMTS.
(insert_init_debug_bind): Likewise.
(insert_init_stmt): Remove redundant check.
(remap_gimple_stmt): Drop debug stmts if the destination
function has var-tracking assignments disabled.
* gcc.dg/lto/pr64415_0.c: New testcase.
* gcc.dg/lto/pr64415_1.c: Likewise.
