Subject: The new x86 gas in binutils.
Date: Mon, 27 Feb 1995 22:20:00 -0000 [thread overview]

Hi,
I have been trying to compile the new binutils snapshot under Linux
for a while now. I am usung gas-950222. I have found the following
things:
1. Some 16 bit supports were added to the binutils. Some assembly
codes in the Linux C library had to be modified to assembler.
One example is I had to change "popfl" to just "popf". There
may be more in the Linux kernel code. I am not sure if that is
a feature or a bug :-(.
2. The new binutils are very unstable for ELF with PIC. I couldn't
use gas/ld in gas-950222 to make a shared Linux C library in
ELF. I had to go back to my private version, 2.5.2.7.
I am afraid the current new binutils are not usable for Linux and
once when they get fixed some asm code in the Linux kernel may
have to be modified.
