#define FATAL ( message ) FatalError(__FILE__, __LINE__, message)

Reports a fatal error that causes the program to terminate. This should only be used for cases where there is an internal error in the compiler.

Function Documentation

void Debug	(	SourcePos	p,
		const char *	format,
			...
	)

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.

Definition at line 447 of file util.cpp.

References lPrintBugText(), and stderr.

void GetDirectoryAndFileName	(	const std::string &	currentDir,
		const std::string &	relativeName,
		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.

uint32_t RoundUpPow2 ( uint32_t v ) [inline]

Rounds up the given value to the next power of two, if it isn't a power of two already.

Referenced by Module::AddFunctionDeclaration(), and FunctionEmitContext::LaunchInst().

int StringEditDistance	(	const std::string &	str1,
		const std::string &	str2,
		int	maxDist
	)

Returns the number of single-character edits needed to transform between the two strings.

Parameters:

str1	First string
str2	Second string
maxDist	Maximum number of single-character edits allowed

Returns:: Number of single-character edits to transform from str1 to str2, or maxDist+1 if it's not psosible to do so in fewer than maxDist steps

void Warning	(	SourcePos	p,
		const char *	format,
			...
	)

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