--- Comment #9 from Martin Jambor <jamborm at gcc dot gnu.org> 2011-04-20 18:17:14 UTC --- Actually, IPA-CP is clearly involved, the function we're inlinig to is: (gdb) call debug_generic_expr(id->dst_fn) _ZN10xalanc_1_818XalanDOMStringPoolC2Emmm.constprop.15285 Looking at the WPA cgraph dump, it is apparent that also the src_fn is cloned by IPA-CP. However, it remains to be seen why the original and not the clone is being inlined here. When I look at the ASM name of the src function: (gdb) call debug_generic_expr(decl_assembler_name(id->src_fn)) _ZN10xalanc_1_818XalanDOMStringPoolC2Emmm.9230 And then it up in WPA cgraph_node, it shows no callers or callees at all: __base_ctor /77004(-1) @0x7f91ca86f000 (asm: _ZN10xalanc_1_818XalanDOMStringPoolC2Emmm) availability:n ot_available local prevailing_def_ironly finalized called by: calls: References: Refering this function: aliases & thunks: __comp_ctor /77005 (asm: _ZN10xalanc_1_818XalanDOMStringPoolC1Emmm) So I don't quite understand how it can be scheduled to be inlined...
