By default, the \*(C+ output is a complete +program that builds the module, verifies it and then emits the module as +\&\s-1LLVM\s0 assembly. This technique assists with testing because the input to +\&\fBllvm2cpp\fR and the output of the generated \*(C+ program should be identical. +.PP +If \fIfilename\fR is omitted or is \f(CW\*(C`\-\*(C'\fR, then \fBllvm2cpp\fR reads its input from +standard input. +.PP +If an output file is not specified with the \fB\-o\fR option, then +\&\fBllvm2cpp\fR sends its output to a file or standard output by following +these rules: +.IP "\(bu" 4 +If the input is standard input, then the output is standard output. +.IP "\(bu" 4 +If the input is a file that ends with \f(CW\*(C`.bc\*(C'\fR, then the output file is of +the same name, except that the suffix is changed to \f(CW\*(C`.cpp\*(C'\fR. +.IP "\(bu" 4 +If the input is a file that does not end with the \f(CW\*(C`.bc\*(C'\fR suffix, then the +output file has the same name as the input file, except that the \f(CW\*(C`.cpp\*(C'\fR +suffix is appended. +.SH "OPTIONS" +.IX Header "OPTIONS" +.IP "\fB\-f\fR" 4 +.IX Item "-f" +Force overwrite. Normally, \fBllvm2cpp\fR will refuse to overwrite an +output file that already exists. With this option, \fBllvm2cpp\fR +will overwrite the output file and replace it with new \*(C+ source code. +.IP "\fB\-\-help\fR" 4 +.IX Item "--help" +Print a summary of command line options. +.IP "\fB\-f\fR" 4 +.IX Item "-f" +Normally, \fBllvm2cpp\fR will not overwrite an existing output file. With this +option, that default behavior is changed and the program will overwrite existing +output files. +.IP "\fB\-o\fR \fIfilename\fR" 4 +.IX Item "-o filename" +Specify the output file name. If \fIfilename\fR is \f(CW\*(C`\-\*(C'\fR, then \fBllvm2cpp\fR +sends its output to standard output. +.IP "\fB\-funcname\fR \fIfunctionName\fR" 4 +.IX Item "-funcname functionName" +Specify the name of the function to be generated. The generated code contains a +single function that produces the input module. By default its name is +\&\fImakeLLVMModule\fR. The \fB\-funcname\fR option overrides this default and allows +you to control the name of the generated function. This is handy in conjunction +with the \fB\-fragment\fR option when you only want \fBllvm2cpp\fR to generate a +single function that produces the module. With both options, such generated code +could be \fI#included\fR into another program. +.IP "\fB\-for\fR" 4 +.IX Item "-for" +Specify the name of the thing for which \*(C+ code should be generated. By default +the entire input module is re\-generated. However, use of the various \fB\-gen\-*\fR +options can restrict what is produced. This option indicates what that +restriction is. +.IP "\fB\-gen\-program\fR" 4 +.IX Item "-gen-program" +Specify that the output should be a complete program. Such program will recreate +\&\fBllvm2cpp\fR's input as an \s-1LLVM\s0 module, verify that module, and then write out +the module in \s-1LLVM\s0 assembly format. This is useful for doing identity tests +where the output of the generated program is identical to the input to +\&\fBllvm2cpp\fR. The \s-1LLVM\s0 DejaGnu test suite can make use of this fact. This is the +default form of generated output. +.Sp +If the \fB\-for\fR option is given with this option, it specifies the module +identifier to use for the module created. +.IP "\fB\-gen\-module\fR" 4 +.IX Item "-gen-module" +Specify that the output should be a function that regenerates the module. It is +assumed that this output will be #included into another program that has already +arranged for the correct header files to be #included. The function generated +takes no arguments and returns a \fIModule*\fR. +.Sp +If the \fB\-for\fR option is given with this option, it specifies the module +identifier to use in creating the module returned by the generated function. +.IP "\fB\-gen\-contents\fR" 4 +.IX Item "-gen-contents" +Specify that the output should be a function that adds the contents of the input +module to another module. It is assumed that the output will be #included into +another program that has already arranged for the correct header files to be +#included. The function generated takes a single argument of type \fIModule*\fR and +returns that argument. Note that Module level attributes such as endianess, +pointer size, target triple and inline asm are not passed on from the input +module to the destination module. Only the sub-elements of the module (types, +constants, functions, global variables) will be added to the input module. +.Sp +If the \fB\-for\fR option is given with this option, it specifies the module +identifier to set in the input module by the generated function. +.IP "\fB\-gen\-function\fR" 4 +.IX Item "-gen-function" +Specify that the output should be a function that produces the definitions +necessary for a specific function to be added to a module. It is assumed that +the output will be #included into another program that has already arranged +for the correct header files to be #included. The function generated takes a +single argument of type \fIModule*\fR and returns the \fIFunction*\fR that it added to +the module. Note that only those things (types, constants, etc.) directly +needed in the definition of the function will be placed in the generated +function. +.Sp +The \fB\-for\fR option must be given with this option or an error will be produced. +The value of the option must be the name of a function in the input module for +which code should be generated. If the named function does not exist an error +will be produced. +.IP "\fB\-gen\-inline\fR" 4 +.IX Item "-gen-inline" +This option is very analagous to \fB\-gen\-function\fR except that the generated +function will not re-produce the target function's definition. Instead, the body +of the target function is inserted into some other function passed as an +argument to the generated function. Similarly any arguments to the function must +be passed to the generated function. The result of the generated function is the +first basic block of the target function. +.Sp +The \fB\-for\fR option works the same way as it does for \fB\-gen\-function\fR. +.IP "\fB\-gen\-variable\fR" 4 +.IX Item "-gen-variable" +Specify that the output should be a function that produces the definitions +necessary for a specific global variable to be added to a module. It is assumed +that the output will be #included into another program that has already arranged +for the correct header files to be #included. The function generated takes a +single argument of type \fIModule*\fR and returns the \fIGlobalVariable*\fR that it +added to the module. Note that only those things (types, constants, etc.) +directly needed in the definition of the global variable will be placed in the +generated function. +.Sp +The \fB\-for\fR option must be given with this option or an error will be produced. +THe value of the option must be the name of a global variable in the input +module for which code should be generated. If the named global variable does not +exist an error will be produced. +.IP "\fB\-gen\-type\fR" 4 +.IX Item "-gen-type" +Specify that the output should be a function that produces the definitions +necessary for specific type to be added to a module. It is assumed that the +otuput will be #included into another program that has already arranged for the +correct header files to be #included. The function generated take a single +argument of type \fIModule*\fR and returns the \fIType*\fR that it added to the +module. Note that the generated function will only add the necessary type +definitions to (possibly recursively) define the requested type. +.Sp +The \fB\-for\fR option must be given with this option or an error will be produced. +The value of the option must be the name of a global type in the input module +for which code should be generated. If the named type does not exist an error +will be produced. +.IP "\fB\-stats\fR" 4 +.IX Item "-stats" +Show pass statistics (not interesting in this program). +.IP "\fB\-time\-passes\fR" 4 +.IX Item "-time-passes" +Show pass timing statistics (not interesting in this program). +.IP "\fB\-version\fR" 4 +.IX Item "-version" +Show the version number of this program. +.SH "EXIT STATUS" +.IX Header "EXIT STATUS" +If \fBllvm2cpp\fR succeeds, it will exit with 0. Otherwise, if an error +occurs, it will exit with a non-zero value. +.SH "SEE ALSO" +.IX Header "SEE ALSO" +llvm-as tblgen +.SH "AUTHORS" +.IX Header "AUTHORS" +Written by Reid Spencer (<http://hlvm.org>). |
