Subject: Re: [PATCH]mips: ldso: dlopen with flag RTLD_NOW should look up the
symbols
After reading eglibc code, I find it's much similar to uclibc
ldso/ldso/mips/elfinterp.c:_dl_perform_mips_global_got_relocations.
See
http://www.eglibc.org/svn/branches/eglibc-2_18/libc/ports/sysdeps/mips/dl

(1)mipsel-linux-gnu 4.8.4(compiled by Broadcom)
mipsel-linux-gnu-gcc 4.8.4
binutils 2.24 (GNU ld (GNU Binutils) 2.24.0.20140801 Linaro 2014.08)
libc 2.18-2013.10
It's not uclibc.
I do further test in this platform.

open ./libtest_mips.so fail.

I think this support was added (I know that there is PLT support for MIPS in the
binutils linker). I have cc'd Richard Sandiford to confirm.

Andrew, thanks for your reply. You are a mips engineer~
I have a following example for dlopen problem, which I tested a few days ago,
but I have no mips environment these days. Would you mind to test it for me.
Many thanks.
Many thanks for the testcase I will give it a try.

Andrew, thanks for your reply. You are a mips engineer~

for me. Many thanks.
Example:
File main.cpp
#include stdio.h
#include dlfcn.h
typedef void
Reason:
MIPS ELF strategy is so different from other architectures like x86 and arm.
When fPIC enabled in x86 and arm, .rel.plt section is generated after
.rel.dyn section, and the dependency of the library (like the function and
object) . But MIPS only generates .rel.dyn section for the
17 matches
