However these days modern gcc apparently got better at not being influenced by such constructs (which is good in general) and therefore such workaround is of no real advantage anymore. The good news is that gcc (from version 4.1.0) is now fixed with regards to the defficiency this workaround was trying to address. For those interested the patch can easily be backported to older gcc versions and can be found here: http://gcc.gnu.org/cgi-bin/cvsweb.cgi/gcc/gcc/config/arm/arm.c.diff?r1=1.476&r2=1.478 and also here: http://savannah.gnu.org/cgi-bin/viewcvs/gcc/gcc/gcc/config/arm/arm.c.diff?r1=text&tr1=1.476&r2=text&tr2=1.478&diff_format=u Signed-off-by: Nicolas Pitre Signed-off-by: Russell King --- include/asm-arm/arch-pxa/hardware.h | 18 +++--------------- include/asm-arm/arch-sa1100/hardware.h | 18 ++---------------- 2 files changed, 5 insertions(+), 31 deletions(-) diff --git a/include/asm-arm/arch-pxa/hardware.h b/include/asm-arm/arch-pxa/hardware.h index 72b04d846a2..cf35721cfa4 100644 --- a/include/asm-arm/arch-pxa/hardware.h +++ b/include/asm-arm/arch-pxa/hardware.h @@ -44,24 +44,12 @@ #ifndef __ASSEMBLY__ -#if 0 -# define __REG(x) (*((volatile u32 *)io_p2v(x))) -#else -/* - * This __REG() version gives the same results as the one above, except - * that we are fooling gcc somehow so it generates far better and smaller - * assembly code for access to contigous registers.
