Bug ID: 18837
Summary: gold does not handle linker-scripts with inputs
Product: binutils
Version: 2.25
Status: NEW
Severity: critical
Priority: P2
Component: gold
Assignee: ccoutant at gmail dot com
Reporter: rguenth at gcc dot gnu.org
CC: ian at airs dot com
Target Milestone: ---
.section .gnu.lto_.debug_info,"",@progbits
.hidden t.c.f0aceea6
.globl t.c.f0aceea6
t.c.f0aceea6:
.long 0x31
.value 0x4
.long .Ldebug_abbrev1
.section .gnu.lto_.debug_abbrev,"",@progbits
.Ldebug_abbrev1:
.uleb128 0x1
.section .gnu.lto_.debug_str,"MS",@progbits,1
.string "/abuild/rguenther/trunk-g/gcc"
> as -o t.o t.s
and script
SECTIONS {
.debug_info : { t.o(.gnu.lto_.debug_info) }
.debug_abbrev : { t.o(.gnu.lto_.debug_abbrev) }
.debug_str : { t.o(.gnu.lto_.debug_str) }
}
and trying to have it link from t.o input sections to debug-info sections
doesn't result in any success (nor do I have an idea how to debug it).
> ld.gold -o x script
> readelf -S x
There are 5 section headers, starting at offset 0xb0:
Section Headers:
[Nr] Name Type Address Offset

[ 0] NULL 0000000000000000 00000000

using a partial link or adding a dummy object and using -T script doesn't
change anything. GOLD also doesn't like parsing
SECTIONS {
.debug_info : { HIDDEN(t.c.f0aceea6 = .); t.o(.gnu.lto_.debug_info) }
}
btw. so assigning new symbols doesn't work (fortunately I ended up not
needing that).
This bug makes gold completely unable to handle what will be the new way
to do debuginfo with GCC and -flto (so called early debug with LTO).
