Description Mike 2014-03-16 04:50:10 CET 
* arm-none-eabi-gdc with ARM thumb support built 2014-03-16 from github 4.8 branch.
* built using instructions on wiki (http://wiki.dlang.org/Bare_Metal_ARM_Cortex-M_GDC_Cross_Compiler)

*********** Code to reproduce ***********
import gcc.attribute;

@attribute("forceinline") static void test()
{
    trace.WriteLine("Here");
}

void main()
{
    test();
}

*********** Output ***********

Comment 1 Mike 2014-03-16 09:14:43 CET 
The following test on Arch Linux 64 results in the same error.  Changing platform attribute to 'All'

************* Code to reproduce **************
import std.stdio;
import gcc.attribute;

@attribute("forceinline") static void test()
{
   writeln("here");
}

void main()
{
   test();
}

gdc --version
gdc (GCC) 4.8.2 20130725 (prerelease)

compiled with simply 'gdc main.d'
Comment 2 Iain Buclaw 2014-03-16 09:56:57 CET 
Looks like the frontend devs changed the behaviours of optimize/interpret, again.  This'll need adding to the testsuite to catch any future changes.

*PATCH*
