Changes between ecm-6.2.3 and ecm-6.3:
* New assembly code for 64-bit PowerPC (thanks to Philip McLaughlin)
* Allow several processes to write to the same -save file
* More routines in new P+-1 stage 2 use multi-threading in OpenMP build
* Fixed incompatibility with GMP 5.0.0
* Fixed several bugs, and now check return value from malloc() calls
* Fixed linking of GMP which prevented successful builds under Darwin
(and presumably other systems)
* Allow use of x86_64 asm code under MinGW
Changes between ecm-6.2.2 and ecm-6.2.3:
* Fixed incompatibility with GMP 4.3.0 when testing version in configure
* SSE2 asm code for Visual C added in stage 2 NTT code
* Small improvement to x86_64 mulredc asm code, slight speedup on Core 2
* Fixed incorrect carry propagation in subquadratic REDC code which
could lead to incorrect arithmetic in rare cases
* Fixed memory leak with -v parameter when factor was found in ECM stage 1
* Fixed bug which caused only one ECM curve to be run in spite of -c
parameter if input line did not end in newline
* Assembler mulredc code enabled by default on x86_64
Changes between ecm-6.2.1 and ecm-6.2.2:
* Updated build project files for Visual C by Brian Gladman, also adds
missing NTT_GFP_TWIDDLE_DI[FT]_BREAKOVER defines in VC parameter file
* Fixed uninitialised parameter to P-1 probability computation
* In tune.c : fixed generation of NTT_GFP_TWIDDLE_DI[FT]_BREAKOVER values,
avoid calling cputime() excessively often when timing short functions,
fixed access to uninitialised memory
* Fixed serious split infinitive in configure script (thanks Paul Leyland)
* Removed unnecessary carry propagation in x86_64 mulredc code, slight
speedup (thanks Philip McLaughlin)
* Fixed non-portable PIC code in x86_64/redc.asm
* Fixed problem with pattern matching host type names in configure.in
* Converted binary constants in spv.c and ntt_gfp.c to hexadecimal,
some assembler do not support binary constants
