Subject: bal instruction in gcc 3.x
Date: Tue, 19 Jul 2005 22:00:20 +0530 [thread overview]
Message-ID: <f07e6e05071909301c212ab4@mail.gmail.com> (raw)
We are facing a problem when U-boot is compiled with gcc 3.x
U-boot uses the following instruction in one of the files.
bal jump_to_symbol
This code gets compiled without any problem with gcc2. However, if I
compile the code
with gcc3, it exits with the error "Cannot branch to unknown symbol".
What should we do to circumvent this problem ?
I replaced
bal jump_to_symbol
by
la t9, jump_to_symbol
jalr t9
Then code gets compiled properly without any problem. Please let me
know, whether this
is correct way of fixing the problem. I am newbie to MIPS assembly
language. Why this
change is required with gcc 3.x compiler ?
TIA,
