%*()

Turns all tokens of its single argument non-frozen.

%**()

Same as %*, but expands its argument first

These operators can be used to create sophisticated macros, as demonstrated in the

Dwarf2 header that comes with the standard distribution. However, as they tend to make the

code harder to follow, use should be considered with care.

10.6.4

Predefined macros

The assembler defines a set of macros available for use.

__VERSION_NUM__

This macro expands to six digits hexadecimal integer 0xJJNNCC where JJ, NN and CC are,

respectively, the major, minor, and micro version numbers.

__VERSION__

This macro expands to a string containing the current version number.

__FILE__

This macro expands to a string and features the original file name (as it appears in the

command line or the including '#include' directive) within which it appears.

__ABS_FILE__

This macro expands to a string and features the absolute path to the file name (as it appears

in the command line or the including '#include' directive) within which it appears.

__LINE__

This macro expands to the current number of source lines.

__DATE__

This macro expands to a string containing the current date.

__TIME__

This macro expands to a string containing the current time.
