--- Comment #7 from H.J. Lu <hjl.tools at gmail dot com> ---
Gold didn't properly align the NT_GNU_PROPERTY_TYPE_0 note:
[hjl@gnu-cet-1 simple-linux]$ make LD=ld.gold
gcc -g -fcf-protection -c -o test.o test.S
gcc -g -fcf-protection -c -o start.o start.S
gcc -g -fcf-protection -c -o syscall.o syscall.S
ld.gold -o test test.o start.o syscall.o
./test hello world
[hjl@gnu-cet-1 simple-linux]$ readelf -l test
Elf file type is EXEC (Executable file)
Entry point 0x400151
There are 3 program headers, starting at offset 64
Program Headers:
Type Offset VirtAddr PhysAddr
FileSiz MemSiz Flags Align
LOAD 0x0000000000000000 0x0000000000400000 0x0000000000400000
0x00000000000001f0 0x00000000000001f0 R E 0x1000
LOAD 0x0000000000001000 0x0000000000401000 0x0000000000401000
0x0000000000000000 0x0000000000000000 RW 0x1000
NOTE 0x00000000000000e8 0x00000000004000e8 0x00000000004000e8
0x0000000000000030 0x0000000000000030 R 0x4
Section to Segment mapping:
Segment Sections...
00 .note.gnu.property .text .eh_frame
01 .data .bss
02 .note.gnu.property
[hjl@gnu-cet-1 simple-linux]$
The NT_GNU_PROPERTY_TYPE_0 note follows gABI and should have 8 byte
alignment for 64-bit ELF.
