Hi Samba I noticed that the crc32 function in lib/crc32.c is somewhat inefficient. This little patch will reduce the inner loop from 10 instructions to 8 instructions on x86 with gcc. gcc can't figure out this simple optimization by itself on x86. Further optimization is possible by using the impl. in the linux 2.5 kernel, but...

FYI, The CRC64 intrinsics were renamed to CRC32 since there is no such thing. See below for details.

Dear R-develers, Antoine Lucas suggested extending my small digest package (which provides md5 and sha-1 digests of R objects, which it are serialized if needed) with a crc32 function, and provided a fairly complete patch. We are now wondering if we should play it safe and bundle crc32.c (plus utils) in the digest sources (as I do with md5 and sha1), or if we can assume that crc32 is present on all R platforms thanks to zlib. Is that the case? If so, is it a good id...

What about multiple errors detection with crc32? Is it work? Thanks.

Hi All. Damien merged a bunch of changes today which caused compile errors on a few platforms (which you can see live and in colour at [0]). a) Solaris, early AIX: ../crc32.c:100: `u_int32_t? undeclared (first use in this function) On these platforms u_int32_t is defined in defines.h which is not included by crc32.c. Fixed by attached patch. b) PAM platforms (Redhat, Solaris once a) is fixed, probably others) gcc -o sshd sshd.o [snip] auth2-kbdint.o: In function `...

I found how to build CRC32 table for Ogg in JS, if anyone interested: function _makeCRC32Table() { // From https://stackoverflow.com/questions/53438815/hot-to-build-crc32-table-for-ogg const polynomial = 79764919; const mask = 2147483648; const CRCTable = new Uint32Array(256); for (let i = 256; i--;) {...

OpenSSH defines a function crc32(), and so does the zlib library. This is at best confusing (since they are different functions with different prototypes), and at worst a source of crashes. I found this problem getting OpenSSH up and running on Darwin, which turned out to be calling the wrong function. My bandaid was to includ...

...running program. Is it all or nothing? What if the calling program new it needed a specific module from the larger optimized "package"? Can the original modules, now combined into the one .bc file, get loaded individually? For example, using Java, suppose I wanted to use java.util.zip.CRC32 to compute a checksum in a program. That class (module) is delivered to me as a java.util.zip "package". That is, it is the result of running llvm-link to produce a single bytecode file that includes all the classes with java.util.zip prefix. But (for some mysterious reason) the java.uti...
