Aldy Hernandez <aldyh at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jason at gcc dot gnu.org --- Comment #5 from Aldy Hernandez <aldyh at gcc dot gnu.org> --- Jason, this behavior exists prior to the debug-early work. For the 1.ii/2.ii testcase in comment 4 we are generating a DIE for a __base_dtor. First we retrofit the declaration with force_decl_die, and use this DIE as the basis for a DW_AT_specification variant. Eventually dwarf2out_abstract_function() gets called on this DW_AT_specification variant and we annotate it with DW_AT_inline. This DW_AT_specification variant, already has location info which is why we fail the assert. It was my understanding that DW_AT_inline cannot appear in conjunction with location info. I added the check_die() code to a branch of mainline immediately before my work, and it ICEs similarly to current mainline with a problematic DIE of: DIE 0: DW_TAG_subprogram (0x7ffff03885a0) abbrev id: 0 offset: 0 mark: 0 DW_AT_specification: die -> 0 (0x7ffff03884b0) DW_AT_low_pc: label: *.LFB0 DW_AT_high_pc: label: *.LFE0 DW_AT_frame_base: location descriptor: (0x7ffff03885f0) DW_OP_call_frame_cfa 0, 0 DW_AT_GNU_all_call_sites: 1 DW_AT_inline: 2 Could you please take a look at this, since it is broken behavior prior to early debug? Perhaps it is expected behavior and we can remove the DW_AT_inline + location check?
