35// See pub_tool_basics.h for the purpose of these macros.
36//
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.
