Re: fembedded-cxx

[Jens-Christian Lache <lache at tu-harburg dot de>]

I encountered an other problem with the C++ compiler:

If I use
  asm volatile ("mov r0, #10":::"r0");
I get :
main.cpp: In function `void taskAfunction()':
main.cpp:49: parse error before `::'

Without telling what reg gets clobberd like
  asm volatile ("mov r0, #10");
works fine.

Thanks,
Jens-Christian
