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,
