__USER_LABEL_PREFIX__

Previous Common Predefined Macros

This macro expands to a single token which is the prefix applied to user labels (symbols visible to C code) in assembly. For example, in the m68k-aout environment it expands to an _, but in the m68k-coff environment (as TIGCC is) it expands to nothing.

This macro will have the correct definition even if '-f(no-)underscores' is in use, but it will not be correct if target-specific options that adjust this prefix are used (e.g. the OSF/rose '-mno-underscores' option).
