-The B<llc> command compiles LLVM bytecode into assembly language for a
+The B<llc> command compiles LLVM source inputs into assembly language for a
specified architecture. The assembly language output can then be passed through
a native assembler and linker to generate a native executable.
The choice of architecture for the output assembly code is automatically
-determined from the input bytecode file, unless the B<-march> option is used to

=head1 OPTIONS
-If I<filename> is - or omitted, B<llc> reads LLVM bytecode from standard input.
-Otherwise, it will read LLVM bytecode from I<filename>.
+If I<filename> is - or omitted, B<llc> reads from standard input. Otherwise, it
+will from I<filename>. Inputs can be in either the LLVM assembly language
+format (.ll) or the LLVM bitcode format (.bc).
If the B<-o> option is omitted, then B<llc> will send its output to standard
output if the input is from standard input. If the B<-o> option specifies -,
