Fields

stgToCmmProfile :: !Profile
Current profile
stgToCmmThisModule :: Module
The module being compiled. This field kept lazy for Cmm/Parser.y which preloads it with a panic
stgToCmmTmpDir :: !TempDir
Temp Dir for files used in compilation
stgToCmmContext :: !SDocContext
Context for StgToCmm phase
stgToCmmEmitDebugInfo :: !Bool
Whether we wish to output debug information
stgToCmmBinBlobThresh :: !(Maybe Word)
Threshold at which Binary literals (e.g. strings) are either dumped to a file and a CmmFileEmbed literal is emitted (over threshold), or become a CmmString Literal (under or at threshold). CmmFileEmbed is only supported with the NCG, thus a Just means two things: We have a threshold, and will be using the NCG. Conversely, a Nothing implies we are not using NCG and disables CmmFileEmbed. See Note [Embedding large binary blobs] in GHC.CmmToAsm.Ppr, and cgTopBinding in GHC.StgToCmm.
stgToCmmMaxInlAllocSize :: !Int
Max size, in bytes, of inline array allocations.
stgToCmmDoTicky :: !Bool
Ticky profiling enabled (cf -ticky)
stgToCmmTickyAllocd :: !Bool
True indicates ticky prof traces allocs of each named thing in addition to allocs _by_ that thing
stgToCmmTickyLNE :: !Bool
True indicates ticky uses name-specific counters for join-points (let-no-escape)
stgToCmmTickyDynThunk :: !Bool
True indicates ticky uses name-specific counters for dynamic thunks
stgToCmmTickyTag :: !Bool
True indicates ticky will count number of avoided tag checks by tag inference.
stgToCmmLoopification :: !Bool
Loopification enabled (cf -floopification)
stgToCmmAlignCheck :: !Bool
Insert alignment check (cf -falignment-sanitisation)
stgToCmmFastPAPCalls :: !Bool
stgToCmmSCCProfiling :: !Bool
Check if cost-centre profiling is enabled
stgToCmmEagerBlackHole :: !Bool
stgToCmmOrigThunkInfo :: !Bool
Push stg_orig_thunk_info frames during thunk update.
stgToCmmInfoTableMap :: !Bool
true means generate C Stub for IPE map, See Note [Mapping Info Tables to Source Positions]
stgToCmmInfoTableMapWithFallback :: !Bool
Include info tables with fallback source locations in the info table map
stgToCmmInfoTableMapWithStack :: !Bool
Include info tables for STACK closures in the info table map
stgToCmmOmitYields :: !Bool
true means omit heap checks when no allocation is performed
stgToCmmOmitIfPragmas :: !Bool
true means don't generate interface programs (implied by -O0)
stgToCmmPIC :: !Bool
true if -fPIC
stgToCmmPIE :: !Bool
true if -fPIE
stgToCmmExtDynRefs :: !Bool
true if -fexternal-dynamic-refs, meaning generate code for linking against dynamic libraries
stgToCmmDoBoundsCheck :: !Bool
decides whether to check array bounds in StgToCmm.Prim or not
stgToCmmDoTagCheck :: !Bool
Verify tag inference predictions.
stgToCmmObjectDeterminism :: !Bool
Enable deterministic code generation (more precisely, the deterministic unique-renaming pass in StgToCmm)
stgToCmmAllowArith64 :: !Bool
Allowed to emit 64-bit arithmetic operations
stgToCmmAllowQuot64 :: !Bool
Allowed to emit 64-bit division operations
stgToCmmAllowQuotRemInstr :: !Bool
Allowed to generate QuotRem instructions
stgToCmmAllowQuotRem2 :: !Bool

stgToCmmAllowExtendedAddSubInstrs :: !Bool
Allowed to generate AddWordC, SubWordC, Add2, etc.
stgToCmmAllowIntMul2Instr :: !Bool
Allowed to generate IntMul2 instruction
stgToCmmAllowWordMul2Instr :: !Bool
Allowed to generate WordMul2 instruction
stgToCmmAllowFMAInstr :: FMASign -> Bool
Allowed to generate FMA instruction
stgToCmmAllowIntWord64X2MinMax :: !Bool
Allowed to generate minmax instructions for Int64X2Word64X2
stgToCmmTickyAP :: !Bool
Disable use of precomputed standard thunks.
stgToCmmSaveFCallTargetToLocal :: !Bool
Save a foreign call target to a Cmm local, see Note [Saving foreign call target to local] for details
stgToCmmVecInstrsErr :: Maybe String
Error (if any) to raise when vector instructions are used, see StgToCmm.Prim.checkVecCompatibility
stgToCmmAvx :: !Bool
check for Advanced Vector Extensions
stgToCmmAvx2 :: !Bool
