Did you test the plugins with all gcc versions (4.5-6)?What's the concern about gcc versions? Just not breaking the build on old compilers? I'm pretty sure powerpc big endian still builds with gcc 4.4.
gcc's plugin support only landed in 4.5, so we don't care about <=4.4.
However if Andrew's only tested on little endian, then that select should be guarded with an "if CPU_LITTLE_ENDIAN". And to build LE you need gcc >= 4.9.
I'm going to give BE a test too just to be sure. -- Andrew Donnellan OzLabs, ADL Canberra andrew.donnellan@au1.ibm.com IBM Australia Limited
