It is primarily used by the GCC front end, and as such, attempts to mimic the interface provided by the default system assembler so that it can act as a "drop-in" replacement.<p> <tt>gccas</tt> performs a number of optimizations on the input program.<p> <h3> OPTIONS </h3> <ul> <li> -help <br> Print a summary of command line options. <p> <li> -o <filename> <br> Specify the output filename which will hold the assembled bytecode. <p> <li> -stats <br> Print statistics. <p> <li> -time-passes <br> Record the amount of time needed for each pass and print it to standard error. <p> <li> -verify <br> Verify each pass result. <p> </ul> <h3> EXIT STATUS </h3> If <tt>gccas</tt> succeeds, it will exit with 0. Otherwise, if an error occurs, it will exit with a non-zero value. <h3>SEE ALSO</h3> <a href="llvm-as.html"><tt>llvm-as</tt></a> <a href="gccld.html"><tt>gccld</tt></a> <HR> <a href="http://llvm.cs.uiuc.edu">LLVM Team</a> </body> </html>
