egcs 970904 miscompile glibc 2.0.5 on linux/alpha

[H.J. Lu]

Hi,

egcs 970904 configured for linux/alpha miscompiled the
dynamic linker in glibc 2.0.5. One file, elf/rtld.c,
is miscompiled by egcs 970904 while gcc 2.7.2.1 is fine.
The symptom is kind of strange. The dynamic linker
runs fine if I do

# elf/ld.so a.out

But when I put elf/ld.so in /lib and do

# a.out

The dynamic linker dies due to a bad address. There
are some differences between asm outputs from gcc 2.7.2.1
and egcs 970904. But I cannot tell what are wrong.

Due to the nature of the dynamic linker, it is very
hard for me to create a small test case. I will be
happy to provide more info.

Thanks.
