|
|
|
|
tblgen - Target Description To C++ Code Generator
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
B<tblgen> [I<options>] [I<filename>]
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
B<tblgen> translates from target description (.td) files into C++ code that can
|
|
be included in the definition of an LLVM target library. Most users of LLVM will
|
|
not need to use this program. It is only for assisting with writing an LLVM
|
|
target backend.
|
|
|
|
The input and output of B<tblgen> is beyond the scope of this short
|
|
introduction. Please see the I<CodeGeneration> page in the LLVM documentation.
|
|
|
|
The F<filename> argument specifies the name of a Target Description (.td) file
|
|
to read as input.
|
|
|
|
=head1 OPTIONS
|
|
|
|
=over
|
|
|
|
=item B<--help>
|
|
|
|
Print a summary of command line options.
|
|
|
|
=item B<-o> F<filename>
|
|
|
|
Specify the output file name. If F<filename> is C<->, then B<tblgen>
|
|
sends its output to standard output.
|
|
|
|
=item B<-I> F<directory>
|
|
|
|
Specify where to find other target description files for inclusion. The
|
|
F<directory> value should be a full or partial path to a directory that contains
|
|
target description files.
|
|
|
|
=item B<-asmwriternum> F<N>
|
|
|
|
Make -gen-asm-writer emit assembly writer number F<N>.

|
=item B<-class> F<class Name>
|
|
|
|
Print the enumeration list for this class.
|
|
|
|
=item B<-print-records>
|
|
|
|
Print all records to standard output (default).
|
|
|
|
=item B<-print-enums>
|
|
|
|
Print enumeration values for a class
|
|
