Works fine in all cases with ELF output. There are problems with many routines (such as OpenWindowTags) if you use HUNKOBJ format. Dunno why, found it myself a while ago.

I have no information about the 601 execution times, but I have the User's manuals for 603e and 604e and there *are* differences. Example: 603-div 37 cycles, 604-div 20 cycles. Another advantage of the 604e is, that it has 7 pipelines (two and a half integer units) and the 603e has only 5 (one and a half integer units). > and another question i have about the float-instructions. the book > tells, that all divide-instructions stall the pipeline for quite a long > time. but what about the eg. fres, fsqrt (not 603) or frsqrte ? fres stalls the FPU pipeline on 603e and 604e for 18 cycles. fsqrt doesn't exist for 603/604 and frsqrte *doesn't* stall the pipeline (executes in 3 cycles). -- _ Frank Wille (frank@phoenix.owl.de) _ // http://home.owl.de/~frank/ \X/ Phx @ #AmigaGer From amigappc-dev-owner@amiga.com.pl Sat Oct 17 15:17:28 1998 Received: from vesuri.Helsinki.FI (jxsaarin@vesuri.helsinki.fi [128.214.205.10]) by amiga.com.pl (8.8.8/8.7.3) with ESMTP id PAA13249 for ; Sat, 17 Oct 1998 15:14:18 +0200 (CEST) Received: from localhost (jxsaarin@localhost) by vesuri.Helsinki.FI (8.8.8/8.8.0) with ESMTP id QAA14954 for ; Sat, 17 Oct 1998 16:14:25 +0300 (EET DST) Date: Sat, 17 Oct 1998 16:14:24 +0300 (EET DST) From: Jyrki O Saarinen To: "AmigaPPC developers' mailing list" Subject: Re: execution-times In-Reply-To: <42120803@phoenix.owl.de> Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Reply-To: AmigaPPC developers' mailing list Sender: amigappc-dev-owner@amiga.com.pl Precedence: list > fres stalls the FPU pipeline on 603e and 604e for 18 cycles. > fsqrt doesn't exist for 603/604 and frsqrte *doesn't* stall the > pipeline (executes in 3 cycles).

Strange, but true. When I try fsqrt with my 604e I'm running in an illegal instruction exception. Try it. :) BTW, frsqrte is not really 1/sqrt(x) but only an estimation.

What exact do I have to do to use functions like printf, fopen,... with gcc for PPC? I have heard about the ixemul bridge from Holger Jacob, but never tried it. Jyrki O Saarinen wrote that it is possible to use the SAS/C ANSI C link library together with egcs. Is this also possible with with gcc and how would I do this? If egcs is better than gcc, what exactly do I need and were can I download or buy it? What about a crosscompiler for linux? What about vbcc? Which compiler would you prefer? For my project (pc-emulator) I need the fastest code possible at all. AFAIK AmigaInc has selected WarpOs as the ppc-system for the future. Can I use SAS/C (gcc, egcs) to produce WarpOs programs?

You can easily build a cross compiler for Linux. Build binutils with target=ppc-elf and build egcs with target=ppc-elf. > What about vbcc? Which compiler would you prefer?

No but OS3.5 will support ppc.library programs too.

I used the standard example with SetAPen() and WritePixel(), but I was interested in the speed-up if some cache flushing is involved, as it is necessary for some graphics functions; e.g., if you want to know for some reason the actual drawing position or some other rastport info inaccesible by means of GetRPAttr(). As you see, the reason was more or less laziness to create another test program.

The compiler and preprocessor will work. I ported vbcc successfully to NetBSD/68k and SCO/i386 (Volker runs it under Linux/Alpha). But you need to find an appropriate linker, assembler, header files and libraries for this platform - or write your own standard libs, as I did for PowerUp and WarpOS. Which Linux, BTW?

Hmm..seems you are talking about bootstrapping vbcc for a system without a (usable) native compiler. I assume he already has a native compiler under Linux. Therefore he just has to build vc, vcpp, vbcc, pasm and vlink using this compiler to get a cross-vbccppc. Volker
