     37 // Note that although the macros here (which are used in asm files) have the
     38 // same name as those in pub_tool_basics.h (which are used in C files), they
     39 // have different definitions.  Actually, on Linux the definitions are the
     40 // same, but on Darwin they are different.  The reason is that C names on
     41 // Darwin always get a '_' prepended to them by the compiler.  But in order to
     42 // refer to them from asm code, we have to add the '_' ourselves.  Having two
     43 // versions of these macros makes that difference transparent, so we can use
     44 // VG_/ML_ in both asm and C files.
     45 //
     46 // Note also that the exact prefixes used have to match those used in
     47 // pub_tool_basics.h.
