The so-called “reference compiler” is the compiler the LRDE develops to (i) prototype what students will have to implement, and to (ii) control the output from student compilers. It might be useful to some to see the name we gave to our options. The following is informative only, the exact contract for a conforming implementation of a Tiger compiler is defined above, Implementation.

Tiger Compiler, Copyright (C) 2004-2018 LRDE.:
0. Tasks:
--task-list list registered tasks
--task-graph show task graph
--task-selection list tasks to be run
--time-report report execution times
1. Parsing:
--scan-trace trace the scanning
--parse-trace trace the parse
--prelude STRING name of the prelude. Defaults to
"builtin" denoting the builtin prelude
-X [ --no-prelude ] don't include prelude
--parse parse a file
--library-display display library search path
-P [ --library-append ] DIR append directory DIR to the search path
-p [ --library-prepend ] DIR prepend directory DIR to the search path
2. Abstract Syntax Tree:
-A [ --ast-display ] display the AST
--ast-dump dump the AST
--tikz-style enable TikZ-style output in AST dumping
2.5 Cloning:
--clone clone the Ast
3. Bind:
--bound default the computation of bindings to
Tiger (without objects nor overloading)
-b [ --bindings-compute ] bind the identifiers
-B [ --bindings-display ] enable bindings display in the AST
--rename rename identifiers to unique names
3. Callgraph:
--escapes-sl-compute compute the escaping static links and the
functions requiring a static link
--escapes-sl-display enable static links' escapes in the AST
--callgraph-compute build the call graph
--callgraph-dump dump the call graph
--parentgraph-compute build the parent graph
--parentgraph-dump dump the parent graph
3. Escapes:
-e [ --escapes-compute ] compute the escaping variables and the
functions requiring a static link

LLVM IR
--llvm-display display the LLVM IR
6. Translation to Low Level Intermediate Representation:

--canon-trace trace the canonicalization of the LIR
-C [ --canon-display ] display the canonicalized IR
--traces-compute make traces
--traces-trace trace the traces computation
--lir-compute translate to LIR (alias for
--trace-compute)
-L [ --lir-display ] display the low level intermediate
representation
7. Target selection:
-i [ --inst-compute ] select the instructions
-R [ --runtime-display ] display the runtime
--inst-debug enable instructions verbose display
--rule-trace enable rule reducing display
--garbage-collection enable garbage collection
-I [ --inst-display ] display the instructions
-Y [ --nolimips-display ] display Nolimips compatible instructions
(i.e., allocate the frames and then
display the instructions
--targeted default the target to MIPS
--target-mips select MIPS as target
--target-ia32 select IA-32 as target
--target-arm select ARM as target
--target-display display the current target
--callee-save NUM max number of callee save registers
--caller-save NUM max number of caller save registers
--argument NUM max number of argument registers
8. Liveness:
-F [ --flowgraph-dump ] dump the flowgraphs
-V [ --liveness-dump ] dump the liveness graphs
-N [ --interference-dump ] dump the interference graphs
9. Register Allocation:
--asm-coalesce-disable disable coalescence
--asm-trace trace register allocation

from the AST to Tiger (without
overloading)
