Douglas Bagnall 6b4d94c987 compression: fix sign extension of long matches (CID 1517275) ... Very long matches would be written instead as very very long matches. We can't in fact hit this because we have a MAX_MATCH_LENGTH defined as 64M, but if we could, it might make certain 2GB+ strings impossible to compress. CID 1517275 (#1 of 1): Unintended sign extension (SIGN_EXTENSION)sign_extension: Suspicious implicit sign extension: intermediate[i + 2UL] with type uint16_t (16 bits, unsigned) is promoted in intermediate[i + 2UL] << 16 to type int (32 bits, signed), then sign-extended to type unsigned long (64 bits, unsigned). If intermediate[i + 2UL] << 16 is greater than 0x7FFFFFFF, the upper bits of the result will all be 1.
