| <h3>NAME</h3> |
| <tt>gccas</tt> |
| |
| <h3>SYNOPSIS</h3> |
| <tt>gccas [options] < filename></tt> |
| |
| <h3>DESCRIPTION</h3> |
| |
| The <tt>gccas</tt> utility takes an LLVM assembly file generated by the <a |
| href="llvmgcc.html">C</a> or <a href="llvmgxx.html">C++</a> frontends and |
| converts it into an LLVM bytecode file. 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> |
| |
