Backend to use for code generation
translation.llvm_via_c:
compile llvm via C
translation.gc:
Garbage Collection Strategy
translation.thread:
enable use of threading primitives
translation.verbose:
Print extra information
translation.debug:
Record extra annotation information
translation.insist:
Try hard to go on RTyping
translation.withsmallfuncsets:
Represent groups of less funtions than this as indices into an array
translation.countmallocs:
Count mallocs and frees
translation.cc:
Specify compiler to use for compiling generated C
translation.profopt:

translation.noprofopt:
Don't use profile based optimization
translation.instrument:
internal: turn instrumentation on
translation.instrumentctl:
internal
translation.output:
Output file name
translation.vanilla:
Try to be as portable as possible, which is not much
translation.no__thread:
don't use __thread for implementing TLS
translation.compilerflags:
Specify flags for the C compiler
translation.linkerflags:
Specify flags for the linker (C backend only)
translation.simplifying:
Simplify flow graphs
translation.builtins_can_raise_exceptions:
When true, assume any call to a 'simple' builtin such as 'hex' can raise an arbitrary exception
translation.list_comprehension_operations:
When true, look for and special-case the sequence of operations that results from a list comprehension and attempt to pre-allocate the list
translation.fork_before:
(UNIX) Create restartable checkpoint before step

Backend Optimization Options
translation.backendopt.inline:
Do basic inlining and malloc removal

Dotted name of an heuristic function for inlining
translation.backendopt.print_statistics:
Print statistics while optimizing
translation.backendopt.merge_if_blocks:
Merge if ... elif chains
translation.backendopt.raisingop2direct_call:
Transform operations that can implicitly raise an exception into calls to functions that explicitly raise exceptions
translation.backendopt.mallocs:
Remove mallocs
translation.backendopt.constfold:
Constant propagation
translation.backendopt.heap2stack:
Escape analysis and stack allocation
translation.backendopt.profile_based_inline:
