Function Documentation

int ir_fprintf ( FILE *  f,
const char *  fmt,
  ... 
)

ir_printf.
int ir_obst_vprintf ( struct obstack *  obst,
const char *  fmt,

)

int ir_printf ( const char *  fmt,
  ... 
)

A string formatting routine for ir objects.

Parameters
fmtThe format string.

This function rudimentary implements a kind of printf(3) for ir nodes and adds the following additional conversion specifiers.

  • %t A type name.
  • %e An entity name.
  • %E An entity ld name.
  • %T A tarval.
  • %n A full description of a node.
  • %O The opcode name of an ir node.
  • %N The node number of an ir node.
  • %m The mode name of an ir mode.
  • %B The block node number of the nodes block.
  • %I An ident.
  • %D Print as many white spaces as given in the parameter.
  • %G A debug info (if available) from the given ir node.
  • %B A bitset.
  • %F A Firm object (automatically detected).

int tarval_snprintf ( char *  buf,
size_t  buflen,
ir_tarval tv 
)

Output a tarval in human readable format to a string buffer.

This function is meant for debugging purposes, the string is formated in a way easily understandable for humans. You should not use this for storage or output for other tools (like assemblers), use get_tarval_sub_bits() for these cases.

The final string in "buf" is guaranteed to be zero-terminated (if buflen is at least 1).

Parameters
bufthe output buffer
buflenthe length of the buffer
tvthe tarval
