Sometimes ld uses the default builtin loader script to set the origin of the
text segment despite the commandline parameter -Ttext-segment=ORG. In
particular: binutils-2.20.1 on OpenSolaris (SunOS opensolaris 5.11 snv_111b
i86pc i386 i86pc Solaris) when configured and built to handle 64-bit binaries
via "./configure --enable-64-bit-bfd=yes". -Ttext-segment fails for 64-bit,
works for 32-bit.
Test case:
-----start.s
_start: .globl _start
hlt
-----
$ gcc -m32 -c -o start32.o start.s
$ gcc -m64 -c -o start64.o start.s
$ ld-2.20.1 -Ttext-segment=0x90000000 -o start32 start32.o
$ readelf --segments start32 | grep LOAD
LOAD 0x000000 0x90000000 0x90000000 0x00055 0x00055 R E 0x1000
## WORKS because p_vaddr is 0x90000000, default is 0x08048000.
$ ld-2.20.1 --oformat elf64-x86-64 -m elf_x86_64 -Ttext-segment=0x567000 -o
start64 start64.o
$ readelf --segments start64 | grep LOAD
LOAD 0x0000000000000000 0x0000000000400000 0x0000000000400000
### FAILS because p_vaddr is the default 0x400000, should be the specified
0x567000.
