Plutus Tx compiler options

These options can be passed to the compiler via the OPTIONS_GHC pragma, for instance

{-# OPTIONS_GHC -fplugin-opt PlutusTx.Plugin:dump-uplc #-}
{-# OPTIONS_GHC -fplugin-opt PlutusTx.Plugin:max-simplifier-iterations-uplc=3 #-}

For each boolean option, you can add a no- prefix to switch it off, such as no-typecheck, no-simplifier-beta.

Option	Value Type	Default	Description
conservative-optimisation	Bool	False	When conservative optimisation is used, only the optimisations that never make the program worse (in terms of cost or size) are employed. Implies no-relaxed-float-in, no-inline-constants, no-simplifier-evaluate-builtins, and preserve-logging.
context-level	Int	1	Set context level for error messages.
coverage-all	Bool	False	Add all available coverage annotations in the trace output
coverage-boolean	Bool	False	Add boolean coverage annotations in the trace output
coverage-location	Bool	False	Add location coverage annotations in the trace output
defer-errors	Bool	False	If a compilation error happens and this option is turned on, the compilation error is suppressed and the original Haskell expression is replaced with a runtime-error expression.
dump-compilation-trace	Bool	False	Dump compilation trace for debugging
dump-pir	Bool	False	Dump Plutus IR
dump-tplc	Bool	False	Dump Typed Plutus Core
dump-uplc	Bool	False	Dump Untyped Plutus Core
inline-constants	Bool	True	Always inline constants. Inlining constants always reduces script costs slightly, but may increase script sizes if a large constant is used more than once. Implied by no-conservative-optimisation.
max-cse-iterations	Int	4	Set the max iterations for CSE
max-simplifier-iterations-pir	Int	12	Set the max iterations for the PIR simplifier
max-simplifier-iterations-uplc	Int	12	Set the max iterations for the UPLC simplifier
optimize	Bool	True	Run optimization passes such as simplification and floating let-bindings.
pedantic	Bool	False	Run type checker after each compilation pass
preserve-logging	Bool	False	Turn off optimisations that may alter (i.e., add, remove or change the order of) trace messages. Implied by conservative-optimisation.
profile-all	ProfileOpts	None	Set profiling options to All, which adds tracing when entering and exiting a term.
relaxed-float-in	Bool	True	Use a more aggressive float-in pass, which often leads to reduced costs but may occasionally lead to slightly increased costs. Implied by no-conservative-optimisation.
remove-trace	Bool	False	Eliminate calls to trace from Plutus Core
simplifier-beta	Bool	True	Run a simplification pass that performs beta transformations
simplifier-evaluate-builtins	Bool	True	Run a simplification pass that evaluates fully saturated builtin applications. Implied by no-conservative-optimisation.
simplifier-inline	Bool	True	Run a simplification pass that performs inlining
simplifier-remove-dead-bindings	Bool	True	Run a simplification pass that removes dead bindings
simplifier-unwrap-cancel	Bool	True	Run a simplification pass that cancels unwrap/wrap pairs
strictify-bindings	Bool	True	Run a simplification pass that makes bindings stricter
target-version	Version	1.1.0	The target Plutus Core language version
typecheck	Bool	True	Perform type checking during compilation.
verbosity	Verbosity	Quiet	Set logging verbosity level (0=Quiet, 1=Verbose, 2=Debug)
