data Sequel Source #

A Sequel tells what to do with the result of this expression

Constructors

Return	Return result(s) to continuation found on the stack.
AssignTo
Fields [LocalReg] Put result(s) in these regs and fall through NB: no void arguments here Bool Should we adjust the heap pointer back to recover space that's unused on this path? We need to do this only if the expression may allocate (e.g. it's a foreign call or allocating primOp)

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.

Insert alignment check (cf -falignment-sanitisation)
stgToCmmOptHpc :: !Bool

Check if cost-centre profiling is enabled
stgToCmmEagerBlackHole :: !Bool

stgToCmmOmitYields :: !Bool
true means omit heap checks when no allocation is performed

stgToCmmExtDynRefs :: !Bool

decides whether to check array bounds in StgToCmm.Prim or not
stgToCmmDoTagCheck :: !Bool
Verify tag inference predictions.
