| type Bitmap = [StgWord] | |||||||||||
| A bitmap represented by a sequence of StgWords on the target architecture. These are used for bitmaps in info tables and other generated code which need to be emitted as sequences of StgWords. | |||||||||||
| mkBitmap :: [Bool] -> Bitmap | |||||||||||
| Make a bitmap from a sequence of bits | |||||||||||
| intsToBitmap :: Int -> [Int] -> Bitmap | |||||||||||
Make a bitmap where the slots specified are the ones in the bitmap. eg. [0,1,3], size 4 ==> 0xb. The list of Ints must be already sorted. | |||||||||||
| intsToReverseBitmap :: Int -> [Int] -> Bitmap | |||||||||||
Make a bitmap where the slots specified are the zeros in the bitmap. eg. [0,1,3], size 4 ==> 0x4 (we leave any bits outside the size as zero, just to make the bitmap easier to read). The list of Ints must be already sorted. | |||||||||||
| mAX_SMALL_BITMAP_SIZE :: Int | |||||||||||
| Magic number, must agree with BITMAP_BITS_SHIFT in InfoTables.h. Some kinds of bitmap pack a size/bitmap into a single word if possible, or fall back to an external pointer when the bitmap is too large. This value represents the largest size of bitmap that can be packed into a single word. | |||||||||||
