Bug ID: 28102
Summary: [gas, --gdwarf-5] Duplicate file and dir
Product: binutils
Version: 2.38 (HEAD)
Status: NEW
Severity: normal
Priority: P2
Component: gas
Assignee: unassigned at sourceware dot org
Reporter: vries at gcc dot gnu.org
Target Milestone: ---
Consider test-case ./tui-layout-asm-short-prog.s (based on
gdb/testsuite/gdb.tui/tui-layout-asm-short-prog.S):
...
$ cat ./tui-layout-asm-short-prog.s
.global _start
_start:
.rept 5
nop
.endr
...
Assembled and dwarf-5 generated:
...
$ ~/binutils/install/bin/as --gdwarf-5 --64 -o o.o
./tui-layout-asm-short-prog.s
...
We have:
...
$ readelf -wl o.o
...
The Directory Table (offset 0x22, lines 2, columns 1):
Entry Name
0 (indirect line string, offset: 0x0): .
1 (indirect line string, offset: 0x2): .
The File Name Table (offset 0x30, lines 2, columns 2):
Entry Dir Name
0 0 (indirect line string, offset: 0x4):
tui-layout-asm-short-prog.s
1 1 (indirect line string, offset: 0x20):
tui-layout-asm-short-prog.s
...
In other words, we've got duplicate directories and duplicate files.
