Summary: LTO debug info for early inlined functions missing
Product: gcc
Version: 4.6.0
Status: UNCONFIRMED
Keywords: lto
Severity: normal
Priority: P3
Component: lto
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: rgue...@gcc.gnu.org
FAIL: gcc.dg/guality/pr43329-1.c -O2 -flto line 12 argx == 25
is because we inline foo during early inlining and the BLOCKs of the
inline instance are not emitted. With -fno-early-inlining it succeeds.
That is, the effect of
/* Output the inlining info for this abstract function, since it has been
inlined. If we don't do this now, we can lose the information about the
variables in the function when the blocks get blown away as soon as we
remove the cgraph node. */
(*debug_hooks->outlining_inline_function) (cg_edge->callee->decl);
isn't reflected in the LTO IL and thus gets lost.
The information should still be there in the inlined BLOCKs abstract
origins though, no?
