Bug ID: 16533
Summary: Gold does not set HASENTRY attribute on ARM
Product: binutils
Version: 2.25 (HEAD)
Status: NEW
Severity: normal
Priority: P2
Component: gold

Proposed patch
I've recently detected an inconsistency between ld.bfd and ld.gold on ARM
platforms. It seems that Gold does not set entry flag in ELF header:
# Binutils with --enable-gold=no
$ arm-v7a15v5r0-linux-gnueabi-gcc justmain.c
$ arm-v7a15v5r0-linux-gnueabi-readelf -h a.out
ELF Header:
...
Flags: 0x5000202, has entry point, Version5 EABI,
<unknown>
# Binutils with --enable-gold=default
$ arm-v7a15v5r0-linux-gnueabi-gcc justmain.c
$ arm-v7a15v5r0-linux-gnueabi-readelf -h a.out
ELF Header:
...
Flags: 0x5000000, Version5 EABI
The attached simple patch seems to fix this:
$ arm-v7a15v5r0-linux-gnueabi-readelf -h a.out
ELF Header:
...
Flags: 0x5000002, has entry point, Version5 EABI
