SVN rev 180405 on 2008-07-10 01:33:48Z by edwin
MFC of changes 180234-180236:
On 64 bit architectures, you can run 32 bit executables and the rtld can trace them, but ldd(1) doesn't know yet how to detect them:
[/] root@ed-exigent>ldd `which httpd`
ldd: /usr/local/sbin/httpd: can't read program header
ldd: /usr/local/sbin/httpd: not a dynamic executable
But...
[/] root@ed-exigent>LD_32_TRACE_LOADED_OBJECTS==1 `which httpd`
libm.so.4 => /lib32//libm.so.4 (0x280c8000)
libaprutil-1.so.2 => /usr/local/lib/libaprutil-1.so.2 (0x280de000)
libexpat.so.6 => /usr/local/lib/libexpat.so.6 (0x280f2000)
libiconv.so.3 => /usr/local/lib/libiconv.so.3 (0x28110000)
libapr-1.so.2 => /usr/local/lib/libapr-1.so.2 (0x281fd000)
libcrypt.so.3 => /lib32//libcrypt.so.3 (0x2821d000)
libpthread.so.2 => not found (0x0)
libc.so.6 => /lib32//libc.so.6 (0x28235000)
libpthread.so.2 => /usr/lib32/libpthread.so.2 (0x2830d000)
Added support in ldd(1) for the LD_32_xxx environment variables if
the architecture of the machine is >32 bits. If we ever go to 128
bit architectures this excercise will have to be repeated but thanks
to earlier commits today it will be relative simple.
