COFF sections are accompanied with an auxiliary symbol which includes a checksum. This checksum used to be filled with just zero but this seems to upset LINK.exe when it is processing a /INCREMENTAL link job. Instead, fill the CheckSum field with the JamCRC of the section contents. This matches MSVC's behavior. This fixes PR19666. N.B. A rather simple implementation of JamCRC is given. It implements a byte-wise calculation using the method given by Sarwate. There are implementations with higher throughput like slice-by-eight and making use of PCLMULQDQ. We can switch to one of those techniques if it turns out to be a significant use of time. llvm-svn: 246590 |
