Hi all,
There was a recent change to how the JIT works. Before, you would pass
a flag into the code generator to indicate whether you wanted "fast"
code generation or normal code generation. Now, we have a
finer-grained control over this. An enum value is passed instead of a
boolean flag.
The change you should make: every call to addPassesToEmitFile,
addPassesToEmitFileFinish, addPassesToEmitMachineCode, or
addCommonCodeGenPasses should pass an optimization level enum rather
than true / false for "Fast". The enum is in
llvm/Target/TargetMachine.h:
namespace CodeGenOpt {
enum Level {
Default,
None,
Aggressive
};
}
The "Default" enum is the old, non-fast version. "None" is
now the
"fast" version. "Aggressive" is currently identical to
Default, but
will change in the future to apply more passes to the code.
