Re: SSE & floating point

There a two ways to load a value into a xmm register. To show both methods I used the register method for xmm0 and the memory method for xmm1. I agree that the memory method is best way. It´s also possible to load integers into xmm registers and then convert them in single/double. I extended the pro...

Re: SSE & floating point

Load a xmm register with a single. (dword) Reg32 is a 32bit register, mem32 is a 4 byte memory location. Mov d xmm0, reg32/mem32 Mov d reg32/mem32, xmm0 Load a xmm register with a double. (qword) Reg64 is a 64bit register, mem64 is a 8 byte memory location Mov q xmm0, reg64/mem64 Mov q reg64/mem64, ...

@SARG 0/Conv, int and fix for float --> integer when SSE4_1 feature is not available done with your code for all integer variables except uinteger. I tested simulating the SEE41 lack but check on your side. for uinteger I'm not sure how it could be done. Could you propose a solution. Maybe VCVTS(D/S...

@SARG @frisian Could you execute this code for testing if roundsd is supported or not. On your PC it should display "not supported". Thanks in advance. run your little test and the result is: 802009 roundsd/ss not supported By the way you didn't post the data for optim6 which doesn't work ...

Re: Gas64 (no more use of gcc, only gas) :-)

@SARG The instructions STMXCSR, LDMXCSR, CVTSD2SI and CVTTSD2SI will work on all the CPU's (old and new) To work with CVTSD2SI some extra code is needed, and space for 2x 32bit storage in memory. For testing I created two extra integer variables into the basic file. convert a double/single value to ...

@SARG You have solved some problems, some of my programs are running correct, but the problem with FP calculation stored in a integer still goes wrong. The test crashes the program also command line switch -exx added wil result in no exe file. dim as integer<32> test = 10,answer answer = rnd * 10 pr...

Re: Gas64 (no more use of gcc, only gas) :-)

@SARG I was very excited to see your effort to produce gas64 code, that I tried many programs but forgot to take notes. I hope to make up for it in the next few days. I have tested your fbc64_gas64.exe on small programs (most Rosetta Code stuff) I have a few programs that compiled and run correctly,...
