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

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