John Criswell	ecf32e5	2003-09-11 19:58:03 +0000	[diff] [blame]	18
Chris Lattner	537a02c	2003-10-07 20:01:09 +0000	[diff] [blame]	19	The <tt>gccas</tt> utility takes an LLVM assembly file generated by the <a
				20	href="llvmgcc.html">C</a> or <a href="llvmgxx.html">C++</a> frontends and
				21	converts it into an LLVM bytecode file. It is primarily used by the GCC front
				22	end, and as such, attempts to mimic the interface provided by the default system
				23	assembler so that it can act as a "drop-in" replacement.<p>
