Version 0.9.4_prerelease (....):
|
||||
* fixed: cannot compile on MS Windows when compiling with GCC (Mingw) for 64 bit platform:
|
||||
incorrect size of ttmath::uint and ::sint were used
|
||||
they were 'long' but 'long' is a 32bit type on Windows
|
||||
* fixed: a crash in Big::Add() (buffer overflow)
|
||||
there was an offset calculated from Int type by using Abs() method and a carry was not checked
|
||||
(if there is a carry we should not make addition -- the argument is too small)
|
||||
this had no impact on calculated values because there was a crash (bus error) immediately
|
||||
following program could crash (64bit):
|
||||
typedef ttmath::Big<1, 8> MyBig;
|
||||
ttmath::Parser<MyBig> parser;
|
||||
parser.Parse("2^(2^63) + 1");
|
||||
* fixed: similar problems were in methods Big::BitAnd() Big::BitOr() and Big::BitXor() (bitwise operations)
|
||||
and they could return incorrect values
|
||||
* fixed: in x86_64 asm code (*.asm for Win64) there was in some places esp register used,
|
||||
there should be rsp used instead
|
||||
this affects MS Windows users when they use the asm version (ttmathuint_x86_64_msvc.asm)
