Hello,
From value.h:
/* Pointer to member function. Depends on compiler implementation. */
#define METHOD_PTR_IS_VIRTUAL(ADDR) ((ADDR) & 0x80000000) #define METHOD_PTR_FROM_VOFFSET(OFFSET) (0x80000000 + (OFFSET)) #define METHOD_PTR_TO_VOFFSET(ADDR) (~0x80000000 & (ADDR))
It also depends on the underlying architecture - not very 64-bit friendly :-/
Yuck!
If I'm reading this right, it corresponded to some old compiler's implementation. But nowadays we fake it in value_struct_elt_for_reference. This is a bit tricky to untangle, but I think this could be solved entirely in eval.c (and the one place we print "virtual" and ditching the remaining bits. I wonder if anything in the testsuite exercises this?
