If you have a 64-bit executable with a section whose address starts at higher
than 0xffffffff, the output of a 32-bit size program that targets 64-bit
executables will be wrong:
$ cat test.c
void _start() { }
$ gcc -nostdlib -fPIC -ffreestanding test.c -Wl,-Ttext,0x100000000
$ x86_64-linux-size -Ax a.out
a.out :
section size addr
.text 0x6 0x0
.eh_frame_hdr 0x14 0x8
.eh_frame 0x38 0x20
.comment 0x1d 0x0
Total 0x6f
The expected output is:
$ size -Ax a.out
a.out :
section size addr
.text 0x6 0x100000000
.eh_frame_hdr 0x14 0x100000008
.eh_frame 0x38 0x100000020
.comment 0x1d 0x0
Total 0x6f
I think this patch should fix it:
