| 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> |

| Chris Lattner | 537a02c | 2003-10-07 20:01:09 +0000 | [diff] [blame^] | 25 | <tt>gccas</tt> performs a number of optimizations on the input program.<p> |
