Hi Rolando,
to answer a few points from your previous email:
> the ARM target of the xcode project is not compiling ARM code
It is compiling the arm JIT for x86 architecture: V8 includes a small
simulator which allows it to run, albeit slowly, the arm JIT on non arm
platforms.
> I disabled thumb code generation
V8 does not generate thumb code, so I assume you mean c++ compiled code.
> (assuming target armv6, so no thumb for faster floating point operations)
I am not sure I follow you:
* thumb is present on armv6 CPU
* pre armv7 there are no hardware floating point instructions in thumb
* in armv7, thumb and arm offer the same vfp instructions

sys_* look like "real" functions whereas __ARM_NR_cacheflush was a system
call number, they get call differently (code for v5 and after):
@ r0 = start
@ r1 = size
ldr ip, =sys_dcache_flush
blx ip
@ r0-r1 is now your return value if any, r2-r3 and r12 are now rubbish
assuming the iPhoneOS use a standard ABI of course.
