/* Function: p7_MSVFilter()
* Synopsis: Calculates MSV score, vewy vewy fast, in limited precision.
*
* Purpose: Calculates an approximation of the MSV score for sequence
* <dsq> of length <L> residues, using optimized profile <om>,
* and the one-row DP matrix <ox>. Return the
* estimated MSV score (in nats) in <ret_sc>.
*
* Score may overflow (and will, on high-scoring
* sequences), but will not underflow.
*
* <ox> will be resized if needed. It's fine if it was
* just <_Reuse()'d> from a previous, smaller profile.
*
* The model may be in any mode, because only its match
* emission scores will be used. The MSV filter inherently
* assumes a multihit local mode, and uses its own special
* state transition scores, not the scores in the profile.
*
* Args: dsq - digital target sequence, 1..L
* L - length of dsq in residues
* om - optimized profile
* ox - filter DP matrix (one row)
* ret_sc - RETURN: MSV score (in nats)
*
* Returns: <eslOK> on success.
* <eslERANGE> if the score overflows the limited range; in
* this case, this is a high-scoring hit.
* <ox> may have been resized.
*
* Throws: <eslEMEML> if <ox> reallocation fails.

/*
* Do or undo the 'E8' preprocessing used in LZX. Before compression, the
* uncompressed data is preprocessed by changing the targets of x86 CALL
* instructions from relative offsets to absolute offsets. After decompression,
* the translation is undone by changing the targets of x86 CALL instructions
* from absolute offsets to relative offsets.
*
* Note that despite its intent, E8 preprocessing can be done on any data even
* if it is not actually x86 machine code. In fact, E8 preprocessing appears to
* always be used in LZX-compressed resources in WIM files; there is no bit to
* indicate whether it is used or not, unlike in the LZX compressed format as
* used in cabinet files, where a bit is reserved for that purpose.
*
* E8 preprocessing is disabled in the last 6 bytes of the uncompressed data,
* which really means the 5-byte call instruction cannot start in the last 10
* bytes of the uncompressed data. This is one of the errors in the LZX
* documentation.
*
* E8 preprocessing does not appear to be disabled after the 32768th chunk of a
* WIM resource, which apparently is another difference from the LZX compression
* used in cabinet files.
*
* E8 processing is supposed to take the file size as a parameter, as it is used
* in calculating the translated jump targets. But in WIM files, this file size
* is always the same (LZX_WIM_MAGIC_FILESIZE == 12000000).
