DESCRIPTION

A header file that can be used to incorporate and control debug information. It is switched ON by default; to switch OFF, the code is compiled with 

-DPRODUCTION_CODE

or 

-DNDEBUG

By default it is used for SpiNNaker ARM code; it can also be used in host-side C, by compiling with -DDEBUG_ON_HOST

EXAMPLES

To use, you must ‘hash-include’ debug.h:

Logging errors, warnings and info: 

log_error(17, "error");                    // not the most useful message..
log_warning(0, "variable x = %8x", 0xFF);  // variable printing
log_info("function f entered");            // trace

Function Documentation

◆ log_error()

void log_error ( const char *  message,
  ... 
)
extern

This function logs errors. Errors usually indicate a serious fault in the program, and that it is about to terminate abnormally (RTE).

Calls to this function are rewritten during the build process to be calls to log_mini_error(); the rewrite also encodes the message so that it is handled more efficiently by the binary deployed to SpiNNaker.

Parameters
[in]messageThe user-defined part of the error message.

◆ log_warning()

void log_warning ( const char *  message,
  ... 
)
extern

This function logs warnings.

Calls to this function are rewritten during the build process to be calls to log_mini_warning(); the rewrite also encodes the message so that it is handled more efficiently by the binary deployed to SpiNNaker.

Parameters
[in]messageThe user-defined part of the error message.

◆ log_info()

void log_info ( const char *  message,
  ... 
)
extern

This function logs informational messages. This is the lowest level of message normally printed.

Calls to this function are rewritten during the build process to be calls to log_mini_info(); the rewrite also encodes the message so that it is handled more efficiently by the binary deployed to SpiNNaker.

Parameters
[in]messageThe user-defined part of the error message.

◆ log_debug()

void log_debug ( const char *  message,
  ... 
)
extern

This function logs debugging messages. This level of message is normally not printed except when the binary is built in debug mode.

Calls to this function are rewritten during the build process to be calls to log_mini_debug(); the rewrite also encodes the message so that it is handled more efficiently by the binary deployed to SpiNNaker.

Parameters
[in]messageThe user-defined part of the error message.

◆ float_to_int()

static uint32_t float_to_int ( float  f)
inlinestatic

Type-pun a float as a 32-bit unsigned integer.

Defeats unwanted casting.

Parameters
[in]fThe floating point number
Returns
The integer that is the bits of the float

Definition at line 121 of file debug.h.

◆ double_to_lower()

static uint32_t double_to_lower ( double  d)
inlinestatic

Type-pun the lower 32 bits of a double as a 32-bit unsigned integer.

Defeats unwanted casting.

Parameters
[in]dThe floating point number
Returns
The integer that is the lower bits of the double

Definition at line 142 of file debug.h.

◆ double_to_upper()

static uint32_t double_to_upper ( double  d)
inlinestatic

Type-pun the higher 32 bits of a double as a 32-bit unsigned integer.

Defeats unwanted casting.

Parameters
[in]dThe floating point number
Returns
The integer that is the higher bits of the double

Definition at line 158 of file debug.h.
