Details:
Hello,
I had problems building mldonkey for mips64, and I came up with a patch I
attach for review. The problem was in the CryptoPP.cc file, related to
multiplication of double words.
Since gcc 4.4, the asm constraint 'h' is not there, and I was using gcc
4.5.1.
Once I could build mldonkey, I tried to run it, and some division code in
CryptoPP.cc failed an assertion:
mlnet: src/utils/lib/CryptoPP.cc:3745: void CryptoPP::Divide(CryptoPP::word*,
CryptoPP::word*, CryptoPP::word*, const CryptoPP::word*, unsigned int, const
CryptoPP::word*, unsigned int): Assertion `shiftBits < WORD_BITS' failed.
The gdb session:
(gdb) f 3
#3 0x100983cc in CryptoPP::Divide (R=0x1022ba30, Q=0x1022bac0, T=0x1022bae8,
A=0x1022ba78,
NA=6, B=0x1022b910, NB=4) at src/utils/lib/CryptoPP.cc:3745
3745 assert(shiftBits < WORD_BITS);
(gdb) print shiftBits
$1 = 64
(gdb) print WORD_BITS
$2 = 64
Any idea of what can be wrong in that code? I can debug further if you need.
