Great Job Joblo  

big thank´s ,  increase on i7 2600  +70k/h  means atm up to 475K/h  for this old thing. Wink at Timetravel  , others not tested yet

btw  may i ask you why i cant use the avx ?  is that a limitation of Windows , cpu works only with the sse41 , or corei7 exe´s

hi all ...

ive finally got my old profile back ...

tanx to cyrus ( bct mod ) and a few others - i now have full access to my old profile ... so will be using this one as much as possible from now on ...

the 'crysx' profile will still be in use - but will be only when necessary - not as my standard ...

a lot to sort out now ...

update ...

Tired of seeing all those compiler warnings from algo-gate-api.c? Well the're going away. I found the
way to supress them for selected code segments.

#pragma GCC diagnostic push
#pragma GCC diagnostic ignored "-Wimplicit-function-declaration"
// ignore these warnings
[...]
// until here
#pragma GCC diagnostic pop

These warnings get displayed because algos don't, are for convenience are not required, to declare
their registration functions in base code.

On another note I still hate c pointer arithmetic. Pointer arithmetic should always use byte offsets,
arrays indexes scale to the target size. p+n should always have the same result regardless of
the size of p's target. I wasted the better part of a day fighting with a problem that turned out to
be bad pointer arithmetic.

Since no one has reported it It's probably not a big issue but I have just discovered x11evo is broken
in the latest release. If you have a working version don't upgrade until this is fixed.

It works in 3.5.1, broken in 3.5.2.

Edit: I've got a fix plus a surprise. I still need to finish the other stuff I was working on before the next release.

you can also toggle warnings per kind with CFLAGS :

-Wimplicit-function-declaration vs -Wno-implicit-function-declaration

but they are there for a good reason in general Wink

Agreed, I didn't want to disable them everywhere, just the block of code where I call the
registration functions because these implicit declarations aren't going away. I actually added some includes to
remove some of the others. Most of the remaining warnings are due to the optimized macros.
I'm going to have to do something about those.

I'm doing something different with v3.5.4, I've submitted the code to git but haven't
built the binaries yet. There are two reasons, it's quicker and this release has a higher risk
of problems that I want to shake out.

v3.5.4 contains small code changes to many algos that will take forever to test. I'l wait about a
day for problem reports before making the formal release.

I'd also like confirmation on improvements, it's hard to tell when the improvement is well within
the margin of error.

- x11evo fixed (broken in v3.5.2) and optimized 23% faster
- Small improvements of 1% to 3% on many algos including timetravel,
   xevan and cryptonight.
- More code cleanup and compiler warning reduction.
- Improved checking for missing command line arguments.

OK I know what's wrong. I had to reorder some things for the command line option checking and now the CPU capabilities
check is done before the algo is registered so it doesn't know the algo's features. Speed should be correct for your CPU,
I need to rework that.

Edit: fixed in git, will be included in final release.
