  • JBigI:
    • Replace old non-PIC 62-bit linux libs (GMP 4.1.4 built in 2005) with PIC libs built with GMP 5.0.2. License is LGPLv3. Built by sponge with GCC 4.4.4, downloaded from http://sponge.i2p/files/jbigi/gmp-5.0.2/ For 64-bit processors, both performance testing and the GMP changelog led us to use 5.0.2 for both the 32- and 64-bit versions, even though the files are twice as big. See http://zzz.i2p/topics/306 for discussion and test results. libjbigi-linux-athlon64.so was a 64 bit file; by the new naming standard supported by NativeBigInteger?, it is now a 32-bit file and the 64-bit one is libjbigi-linux-athlon64_64.so. All new 64-bit libs will have _64 appended.

    19jbigi.jar was built by jrandom on Aug 21, 2004 with the jbigi and jcpuid
    210native libraries compiled on linux, winXP (w/ MinGW), and freebsd (4.8). 
     
    2432as it should offer amd64 users better performance than jbigi-win-none.dll
    2533until we get a full amd64 build.

     35================================

     37Updates May/June 2011:
     38  jcpuid:
     39   - jcpuid.c updated to be compatible with -fPIC
     40   - 32 bit libjcpuid-linux-x86.so updated, compiled with -fPIC.
     41   - 64 bit libjcpuid-linux-x86_64.so added, compiled with -fPIC.
     42   - See also javadoc and code in CPUID.java
     43  jbigi:
     44   - k62 and k63 are identical for all except windows; exception added to
     45     NativeBigInteger to use k62 for k63. k63 files deleted.
     46   - All 32 bit linux files updated with GMP 4.3.2, compiled with -fPIC,
     47     except for athlon64 and pentium4, which use GMP 5.0.2.
     48   - All 64 bit linux files updated with GMP 5.0.2.
     49   - libjbigi-windows-athlon64.dll deleted, it was a duplicate of
     50     libjbigi-windows-athlon.dll. NativeBigInteger now uses athlon as
     51     a fallback for all 64-bit processors.
     52   - Note that all new 64 bit files will use the _64 suffix. For example,
     53     the old libjbigi-linux-athlon64.so file was 64 bit; now it is 32 bit
     54     and the 64 bit file is libjbigi-linux-athlon64_64.so.
     55   - The 4.3.2 files are half the size of the 5.0.2 files, and there was
     56     little or no performance difference for 32 bit, so we are using
     57     4.3.2 for 32 bit. For 64-bit processors, both performance testing and
     58     the GMP changelog led us to use 5.0.2 for both the 32- and 64-bit versions.
     59   - See also checkin comments, javadoc and code in NativeBigInteger.java
