...> Here's what happens: > > llvm-as test2_gen.s %% no errors test2_gen.s.bc is produced there's actually no need to assemble this to bitcode: you can pass test2_gen.s directly to opt. At least you can in recent versions of LLVM. > opt -std-compile-opts -S test2_gen.s.bc> test2_opt.s.bc By using -S you ask opt to produce human readable IR rather than bitcode, so you should really output to test2_opt.s. > > %% no errors > %% But now the generated file cannon be disassembled or run > > lli test2_opt.s.bc > lli: error loading program 'test2_opt.s.bc':...
