Bug ID: 82011
Summary: [8 regression] early lto debug causes dsymutil warning
on Darwin
Product: gcc
Version: 8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: debug
Assignee: unassigned at gcc dot gnu.org
Reporter: ro at gcc dot gnu.org
Target Milestone: ---
Target: *-*-darwin*
Created attachment 42062

preprocessed input, assembler output with -dA -fverbose-asm, object file and
executable
Since the early LTO debug patch has landed, I'm seeing a large number of
testsuite
regressions on Darwin, e.g.
FAIL: g++.dg/torture/pr37922.C -O3 -g (test for excess errors)
warning: invalid DWARF generated by the compiler: DIE 0x0000241b has multiple
AT_inline attributes in
'/var/folders/zz/zyxvpxvq6csfxvn_n000087r00021y/T//ccpTfHtT.o'.
The warning is from running dsymutil on the executable, and indeed running
dwarfdump on the corresponding object file finds
0x0000241b: TAG_subprogram [65] *
AT_specification( {0x00000d35} (
"_ZN11rot_mx_infoC4ERK6rot_mx" ) )
AT_decl_line( 469 )
AT_inline( DW_INL_not_inlined )
AT_inline( DW_INL_not_inlined )
AT_sibling( {0x00002481} )
I'm attaching preprocessed input etc. for reference.
