Subject: [U-Boot] [PATCH 2/2] [NEXT] arm926ejs: reduce code size with -msingle-pic-base
Date: Wed, 22 Sep 2010 23:36:29 +0200 [thread overview]
Message-ID: <4C9A76DD.4030604@free.fr> (raw)
In-Reply-To: <AANLkTinmFDTi1wnOxWDrL2a5z7P0+oBxd3cwRKT3nGR4@mail.gmail.com>
As for _TEXT_BASE vs TEXT_BASE, this is normal: TEXT_BASE is the image
base, and _TEXT_BASE is the address of a variable holding the value of
TEXT_BASE, so it's not surprising that they are not equal.
As for your problem: your reports show that start.S sets r10 and r9 as
expected, but that board_init_f does not contain the pic prolog code. I
wonder if you may have built it without -fPIC or -fPIE. Normally with
-fPIE/PIC you should have seen board_init_f (and any function) start
with something like:
c1080690: e59fa120 ldr sl, [pc, #288] ; c10807b8 <board_init_f+0x128>
c1080694: e08fa00a add sl, pc, sl
Can you check the build logs to see which options were applied to
lib/arm/board.c?
I'll try with your CodeSourcery toolchain (I'm using the ELDK 4.2 one),
but there is no reason why it would not be EABI compliant.
Amicalement,
