NOTE: 2nd part changeset for cfe trunk to follow. *** PRE-PATCH ISSUES ADDRESSED - clang api docs fail build from objdir - clang/llvm api docs collide in install PREFIX/ - clang/llvm main docs collide in install - clang/llvm main docs have full of hard coded destination assumptions and make use of absolute root in static html files; namely CommandGuide tools hard codes a website destination for cross references and some html cross references assume website root paths *** IMPROVEMENTS - bumped Doxygen from 1.4.x -> 1.6.3 - splits llvm/clang docs into 'main' and 'api' (doxygen) build trees - provide consistent, reliable doc builds for both main+api docs - support buid vs. install vs. website intentions - support objdir builds - document targets with 'make help' - correct clean and uninstall operations - use recursive dir delete only where absolutely necessary - added call function fn.RMRF which safeguards against botched 'rm -rf'; if any target (or any variable is evaluated) which attempts to remove any dirs which match a hard-coded 'safelist', a verbose error will be printed and make will error-stop. llvm-svn: 103213

=head1 NAME
|
|
|
|
llvm-g++ - LLVM C++ front-end
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
B<llvm-g++> [I<options>] I<filename>
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
The B<llvm-g++> command is the LLVM C++ front end. It is a modified
|
|
version of g++ that compiles C++/ObjC++ programs into native code,
|
|
LLVM bitcode or assembly language, depending upon the options.
|
|
|
|
By default, B<llvm-g++> compiles to native objects just like GCC does. If the
|
|
B<-emit-llvm> option is given then it will generate LLVM bitcode files instead.
|
|
If B<-S> (assembly) is also given, then it will generate LLVM assembly.
|
|
|
|
Being derived from the GNU Compiler Collection, B<llvm-g++> has many
|
|
of g++'s features and accepts most of g++'s options. It handles a
|
|
number of g++'s extensions to the C++ programming language.
|
|
|
|
=head1 OPTIONS
|
|
|
|
=over
|
|
|
|
=item B<--help>
|
|
|
|
Print a summary of command line options.
|
|
|
|
=item B<-S>
|
|
|
|
Do not generate an LLVM bitcode file. Rather, compile the source
|
|
file into an LLVM assembly language file.
|
|
|
|
=item B<-c>
|
|
|
|
Do not generate a linked executable. Rather, compile the source
|
|
file into an LLVM bitcode file. This bitcode file can then be
|
|
linked with other bitcode files later on to generate a full LLVM
|
|
executable.
|
|
|
|
=item B<-o> I<filename>
|
|
|
|
Specify the output file to be I<filename>.
|
|
|
|
=item B<-I> I<directory>
|
|
|
|
Add a directory to the header file search path. This option can be
|
|
repeated.
|
|
|
|
=item B<-L> I<directory>
|
|
|
|
Add I<directory> to the library search path. This option can be
|
|
repeated.
|
|
|
|
=item B<-l>I<name>
|
|
|
|
Link in the library libI<name>.[bc | a | so]. This library should
|
|
be a bitcode library.
|
|
|
|
=item B<-emit-llvm>
|
|
|
|
Make the output be LLVM bitcode (or assembly) instead of native object (or
|
|
assembly).
|
|
|
|
=back
|
|
|
|
=head1 EXIT STATUS
|
|
|
|
If B<llvm-g++> succeeds, it will exit with 0. Otherwise, if an error
|
|
occurs, it will exit with a non-zero value.
