Hi Mikhail, What is mentioned in the reference manual is this: // Evaluates to "cmdline1" if the option "-A" is provided on the // command line; to "cmdline2" if "-B" is provided; // otherwise to "cmdline3". (case (switch_on "A"), "cmdline1", (switch_on "B"), "cmdline2", (default), "cmdline3") What is generated is this: if (A) { ... } if (B) { .... } else { .... } IMO, What should be generated is...

I propose adding something along these lines: def Preprocess : OptionPreprocessor <[  (squash ["O1", "O2", "O3"], "O3"),  (squash ["O1", "O2"], "O2"),  (conflict  (and (switch_on "E"), (switch_on "S"))),  (warning (and (switch_on "E"), (switch_on "S")), "-E conflicts with -S") ]>; The preprocessing code will run once in the beginning. -- () ascii ribbon campaign - against html e-mail /\ www.asciiribbon.org - agains...

.../Base.td hardcodes the -relocation-model=pic option into invocations of llc: def llc : Tool< [(in_language "llvm-bitcode"), (out_language "assembler"), (output_suffix "s"), (cmd_line "llc -relocation-model=pic -f $INFILE -o $OUTFILE"), (actions (case (switch_on "S"), (stop_compilation))) ]>; This is nice on 64 bit systems, but generates slow code on 32 bit x86, and even breaks on 32 bit Windows (using the mingw port); llc spits out a failed assertion there if invoked with -relocation-model=pic.
