Bug ID: 108905
Summary: Debugging information refers to the wrong file
Product: gcc
Version: 11.2.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: lveyde at redhat dot com
Target Milestone: ---
It seems GCC sometimes injects wrong DWARF information regarding the source
file and line.
In particular this shows itself in case of some Linux kernel symbols, for
example __SCT__x86_pmu_handle_irq.
$ /tmp/binutils-gdb/binutils/addr2line -fie vmlinux 0xffffffff81c00290
__SCT__x86_pmu_handle_irq
/tmp/linux-5.15.95/./arch/x86/include/asm/paravirt.h:10
In reality this symbol is generated by macro on line 63 of
arch/x86/events/core.c
source file.
