| |
#define MYDEF a, b, c
__stringify(MYDEF) should be replaced by "a, b, c", but compilation fails because the __stringify macro expects only one argument. Fix it by using variable macro arguments in __stringify and __stringify_1.
Needed in my current NMI safe iret paravirt support work so I can expand a macro containing assembly code into a string.
