Prints a debugging message. These messages are only printed if g->debugPrint is true
. In addition to a program source code position to associate with the message, a printf()-style format string is passed along with any values needed for items in the format string.

void Error | ( | SourcePos | p, |
const char * | format, | ||
... | |||
) |
Prints an error message. It is assumd that compilation can not be successfully completed after an error has been issued, though the system tries to continue compiling as much as possible, in order to be able to issue any subsequent error messages. In addition to a program source code position to associate with the message, a printf()-style format string is passed along with any values needed for items in the format string.

void FatalError | ( | const char * | file, |
int | line, | ||
const char * | message | ||
) |
This function generally shouldn't be called directly, but should be used via the FATAL macro, which includes the file and line number where the error was issued.

void GetDirectoryAndFileName | ( | const std::string & | currentDir, |

std::string * | directory, | ||
std::string * | filename | ||

Given the current working directory and a filename relative to that directory, this function returns the final directory that the resulting file is in and the base name of the file itself.

std::vector<std::string> MatchStrings | ( | const std::string & | str, |
const std::vector< std::string > & | options | ||
) |
Given a string and a set of candidate strings, returns the set of candidates that are "close" to the given string, where distance is measured by the number of single-character changes needed to transform between the two. An empty vector may be returned if none of the options is close to str
.

void PerformanceWarning | ( | SourcePos | p, |
const char * | format, | ||
... | |||

Prints a message about a potential performance issue in the user's code. These messages are purely informative and don't affect the completion of compilation. In addition to a program source code position to associate with the message, a printf()-style format string is passed along with any values needed for items in the format string.

int TerminalWidth | ( | ) |
Returns the width of the terminal where the compiler is running. Finding this out may fail in a variety of reasonable situations (piping compiler output to 'less', redirecting output to a file, running the compiler under a debuffer; in this case, just return a reasonable default.

bool VerifyDataLayoutCompatibility | ( | const std::string & | module_dl, |

Verification routine, which ensures that DataLayout of the module being compiled is compatible with DataLayout of the library. At the moment we allow the library DataLayout to a subset of the module DataLayout (and extra floating point and vector types to be defined for module) or empty library DataLayout.

void Warning | ( | SourcePos | p, |

Prints a warning about an issue found during compilation. Compilation can still continue after warnings; they are purely informative for the user.
