Supervisor Calls on ARM Cortex-M3

[Alex Alexandrov <alexalexsoft2009@xxxxxxxxx>]

Hello,

Do the GCC  C/C++ compilers support supervisor function calls on ARM 
Cortex M3/4 targets?
I mean something like the IAR's "#pragma _swi" or the "__svc" keyword 
used by the RealView compiler.
How can I make the compiler use the "svc" machine instruction when 
calling the function, instead of the regular "branch and link" instruction?
