Description David Daoust CLA 2006-06-05 13:23:22 EDT 
#define mb()  __asm__ __volatile__ ("sync" : : : "memory")

int main(int argc, char **argv) {
	mb();
}

This is an example ppc assembly usage -- note that it is syntactically correct, but gcc on windows will complain about the instructions (which are not x86).

This may mask other errors -- but the parser seems to recover ok.

Patch to support GNU Extended ASM

This patch updates the AbstractGNUSourceCodeParser to accept the GNU asm extensions and adds a test in CompleteParser2Tests.

I'm not storing any of the additional information so for the example above you couldn't tell that the declaration is volatile and only "sync" returned by getAssembly.
