cmmToRawCmm :: Logger -> Profile -> Stream IO CmmGroupSRTs a -> IO (Stream IO RawCmmGroup a) Source #
srtEscape :: Platform -> StgHalfWord Source #
Value of the srt field of an info table when using an StgLargeSRT
closureInfoPtr :: Platform -> DoAlignSanitisation -> CmmExpr -> CmmExpr Source #
Takes a closure pointer and returns the info table pointer
entryCode :: Platform -> CmmExpr -> CmmExpr Source #
Takes an info pointer (the first word of a closure) and returns its entry code
getConstrTag :: Profile -> DoAlignSanitisation -> CmmExpr -> CmmExpr Source #
Takes a closure pointer, and return the *zero-indexed* constructor tag obtained from the info table This lives in the SRT field of the info table (constructors don't need SRTs).
cmmGetClosureType :: Profile -> DoAlignSanitisation -> CmmExpr -> CmmExpr Source #
Takes a closure pointer, and return the closure type obtained from the info table
infoTable :: Profile -> CmmExpr -> CmmExpr Source #
Takes an info pointer (the first word of a closure) and returns a pointer to the first word of the standard-form info table, excluding the entry-code word (if present)
infoTableConstrTag :: Profile -> CmmExpr -> CmmExpr Source #
Takes an info table pointer (from infoTable) and returns the constr tag field of the info table (same as the srt_bitmap field)
infoTableSrtBitmap :: Profile -> CmmExpr -> CmmExpr Source #
Takes an info table pointer (from infoTable) and returns the srt_bitmap field of the info table
infoTableClosureType :: Profile -> CmmExpr -> CmmExpr Source #
Takes an info table pointer (from infoTable) and returns the closure type field of the info table.
funInfoTable :: Profile -> CmmExpr -> CmmExpr Source #
Takes the info pointer of a function, and returns a pointer to the first word of the StgFunInfoExtra struct in the info table.
funInfoArity :: Profile -> CmmExpr -> CmmExpr Source #
Takes the info pointer of a function, returns the function's arity
stdInfoTableSizeW :: Profile -> WordOff Source #
stdInfoTableSizeB :: Profile -> ByteOff Source #
conInfoTableSizeB :: Profile -> Int Source #
stdSrtBitmapOffset :: Profile -> ByteOff Source #
Byte offset of the SRT bitmap half-word which is in the *higher-addressed* part of the type_lit
stdClosureTypeOffset :: Profile -> ByteOff Source #
Byte offset of the closure type half-word
stdPtrsOffset :: Profile -> ByteOff Source #
stdNonPtrsOffset :: Profile -> ByteOff Source #
