[Qemu-devel] qemu-arm: Make commandline args available to semihosting

[Wolfgang Schildbach]

Hello list,

This patch implements the semihosting call to retrieve command line 
arguments from the host environment. Without this patch, neither 
arm-non-eabi-gcc compiled executables (which use semihosting) nor 
ARM-compiler compiled executables can read command line arguments. It 
works for both little- and bigendian executables, in user mode emulation. 

The patch below applies on the 2006-07-31 version of qemu (later versions 
of qemu don't work for me due to aio changes), but merging this into the 
head should be very straightforward. See more text explaining the code in 
http://lists.gnu.org/archive/html/qemu-devel/2006-06/msg00454.html .

Paul, do you want to take a look at this?

Thx,
- Wolfgang
