Function Documentation

◆ clang_compile_llvm()

void clang_compile_llvm ( const char * fn )

Starts up the clang compiler to compile the generated LLVM-IR into a binary.

Parameters

fn	Name of file to compile

◆ create_tmp_generator_program()

void create_tmp_generator_program ( void )

Create a temporary file for a generator program used to determine compilation information.

◆ get_target_datalayout()

char * get_target_datalayout ( void )

Search through GENERATOR_PROGRAM for the target datalayout.

Returns: char* Pointer to target datalayout string

◆ get_target_triple()

char * get_target_triple ( void )

Get the target triple for the current target.

Returns: char* Pointer to the target triple string

◆ get_temp_dir()

const char * get_temp_dir ( void )

Get the default temporary directory.

Returns: const char* String containing temporary directory name

◆ link_globals()

void link_globals ( void )

Link globals.ll to main LLVM file by copying the contents of each LLVM file into a temporary file, then copying back to the main LLVM file.

◆ regex_match()

char * regex_match	(	const char *	regex,
		char *	target_str,
		int	len,
		int	group_index
	)

Simple regex parser.

Parameters

regex	Regular expression to compile
target_str	String to search in
len	Maximum length of the output match, if found
group_index	Index of group to match (0 for no group)

Returns: char* Pointer to the match text if match found, else NULL
