If your program only uses provided libraries, then there is no difference. You can compile it as usual.

There should be no difference if you aren't using -noixemul. But my automated tests cover only a tad more than 0%.

If you are using -noixemul and feed the linker yourself then you have to add the endfile xcrt0.o

If you compile some libraries yourself, you might consider to recompile these.

You're able to create resident programs now using -noixemul. Note that you need the correct libraries (well that applies for all programs and isn't new):

Don't use normal libs for baserel or resident programs and vice versa.
Don't use normal libs for for programs using the fpu and vice versa.
Don't mix baserel and baserel32...
special variants for 68040/60 aren't mandatory but do avoid some fline emulation

Regarding section garbage collection:

The linker ld offers that feature but the amiga implementation was a do-nothing. I added an implementation which attempts to remove duplicate sections containg only a weak function - these are created for template and inline stuff - and maybe a tad more, but it's not a correct garbage collection.

There is room for improvements to create a correct gc implementation, which involves scanning all relocations, the exception stuff and god knows what else.

Find here updated binaries for gcc on AmigaOS: https://franke.ms/download/gcc68.lha

All these programs are compiled with
-Os -noixemul -m68040 -ffast-math -fomit-frame-pointer -resident32
and can be made resident now, maybe this gains some speed, maybe not. On WinUAE there is no difference if the programs are resident, and resident does not count the invokations properly /shrug.

I omitted some files, which are duplicates, so copy:

Code:

c++ to g++,  m68k-amigaos-c++ and m68k-amigaos-g++
gcc to m68k-amigaos-gcc-6.5.0b
m68k-amigaos-ld to ld

Assign GCC: to the install folder and add GCC:bin to the path.
The headers and libs can be taken from the "normal" amiga-gcc stuff.
Use a sufficient stack size - I'm using 100k.
The first invokation of gcc fails on my system... since it can't invoke cc1. All further attempts succeed...

With WinUAE's JIT the difference may be hard to measure, given that it dynamically responds to what code is being executed as part of loading the executable. Switching off the JIT and maybe also enabling cycle-accurate CPU emulation might bring out the differences, but it will test one's patience

That said, there has to be a measurable difference in favour of making cc1/cc1plus resident as opposed to loading them from disk, even if that is a virtual disk which uses proper caching and also resides on an SSD, etc.

The dos.library LoadSeg() implementation is not processing load files as quickly as it perhaps should be doing. It reads the load file using buffered file I/O, using a 1024 byte buffer which will be refilled as needed. From this buffer it will copy the code and data into the respective segment list entries allocated for them, a maximum of 1024 bytes at a time, using a modest "move.l (a1)+,(a0)+" repeated for as many 32 bit words as are currently stored in the buffer. It literally copies one 32 bit word at a time, with no loop unrolling or anything else which would speed up this process.

For the cc1 command this means that some 11 MBytes of code are processed in a loop which reads chunks of 1024 bytes each and copies these, about 11,200 times. The same happens for the much shorter data hunk (barely 75 KBytes in size).

The real kicker is what happens with the relocation information which is applied to the code hunk. For cc1 more than 89,840 individual relocations need to be performed and the format in which these instructions are stored in the load file is not geared towards efficiency.

In a nutshell, the dos.library LoadSeg() implementation devolves into a series of complicated delay loops for a load file as large as the cc1 command

Not doing all of that for each invocation of cc1, etc. really should make a difference at that scale.

I can't seem to print floating point numbers with printf. This is the floattest.c program:

Code:

#include <stdio.h>
int main(void)
{
	printf("%f\n", 0.1);
	return 0;
}

I build it with the following command:

Code:

m68k-amigaos-gcc -O2 -ffast-math -save-temps -fomit-frame-pointer -noixemul -m68060 -m68881 -lm -Wl,-Map=floattest.map -o floattest floattest.c

I also uploaded the executable I built and the source files:
http://bszili.morphos.me/stuff/floattest.zip
It it just prints "%f" instead of the actual float value, so the format string is probably not recognized.
Do I have to link it with another library or the argument order in the command is wrong? I updated to the latest version of the toolchain before testing.

alkis · 13 May 2022, 01:46

I usually play with the order of -lm (i.e first in front of the objects, then after the objects). Sometimes it helps.

BSzili · 13 May 2022, 05:59

Nice, that did the trick! I had to put -lm to the very end after the objects.

bebbo · 13 May 2022, 08:10

simply add -v and have a look (I stripped all non objects/libs):

Code:

 /opt/amiga/libexec/gcc/m68k-amigaos/6.5.0b/collect2 -o floattest /opt/amiga/m68k-amigaos/libnix/lib/ncrt0.o -lm floattest.o -( -lnix20 -lnixmain -lnix -lstubs -lamiga -lgcc -lm -l__m__ -) /opt/amiga/m68k-amigaos/libnix/lib/xcrt0.o

That's the order how ld links the executable. Every entry is visited once. Objects are included as provided. Libs are used to resolve not yet found symbols. The brackets define a loop, what's in the loop is searched again and again until no unresolved symbol was added.
Next thing to know is: there are two implementations of printf - one with floating point support in -lm and one without floating point support in -lnix. Follow the link order and you'll see that it's mandatory to specify the lib after the referring object.
Usually libs are built in a way to avoid picking up too much unused code, sometimes it's unavoidable. And sometimes there is superfluous code in the provided object files:
There -gc-sections may help, which is yet experimental, but it exists.
Using inline and/or c++ may also yield WEAK symbols, which amiga-gcc does support. That stuff is also cleaned up by specifying -gc-sections.

BSzili · 13 May 2022, 09:44

Thanks, this makes perfect sense. In many cases the float-less printf is desirable, when the program uses no floating point math otherwise. I took a note of the -v switch.

mateusz_s · 06 June 2022, 22:13

@bebbo Hi, the online compiler at: https://franke.ms/cex/ no longer works.
Did you stop to supporting it?

mateusz_s · 08 June 2022, 18:29

Ok it works thanks

Really great! Any recommendations what would be the best 'base gcc' archive to use for the includes and libraries?

And if I add the ppc libraries for warpos would I be able to create ppc binaries as well?

Use the includes and libs from the amiga-gcc cross-toolchain.

Is there a flag to make the toolchain use detach.o for startup?

sorry, there isn't a flag.

add the detach.o object to the linked objects and you're set.
Don't use it with resident stuff and select the proper version matching cpu/baserel(32).

Hope it works... I never tried this^^

I'm trying to compile a recent rsync with GCC 6.5. It seems there is a problem with ixemul and dirent.h. During configure of rsync the test for dirent.h fails so in the end DIR is not defined.

I would expect that dirent.h is available when using ixemul (by not giving -noixemul and any -mcrt), as can be seen in the ixemul repo. However, in a simple test I get:

Code:

sh-3.2$ cat de.c
#include <dirent.h>
sh-3.2$ m68k-amigaos-gcc de.c -c
In file included from /opt/amiga/m68k-amigaos/sys-include/dirent.h:7:0,
                 from de.c:1:
/opt/amiga/m68k-amigaos/sys-include/sys/dirent.h:10:2: error: #error "<dirent.h> not supported"
 #error "<dirent.h> not supported"
  ^~~~~

This is obviously not the file from ixemul? It seems to be newlib:

Code:

sh-3.2$ grep -rnw "<dirent.h> not supported" amiga-gcc
amiga-gcc/projects/newlib-cygwin/newlib/libc/include/sys/dirent.h:10:#error "<dirent.h> not supported"
sh-3.2$

Hi,
could you help me with adding assembler .s file to compilation?

I want to include this c2p asm routine into my project:

Thank You in advance

you need to compile that assembly file with VASM

bebbo bye Join Date: Jun 2016 Location: Some / Where Posts: 680	simply add -v and have a look (I stripped all non objects/libs): Code: /opt/amiga/libexec/gcc/m68k-amigaos/6.5.0b/collect2 -o floattest /opt/amiga/m68k-amigaos/libnix/lib/ncrt0.o -lm floattest.o -( -lnix20 -lnixmain -lnix -lstubs -lamiga -lgcc -lm -l__m__ -) /opt/amiga/m68k-amigaos/libnix/lib/xcrt0.o That's the order how ld links the executable. Every entry is visited once. Objects are included as provided. Libs are used to resolve not yet found symbols. The brackets define a loop, what's in the loop is searched again and again until no unresolved symbol was added. Next thing to know is: there are two implementations of printf - one with floating point support in -lm and one without floating point support in -lnix. Follow the link order and you'll see that it's mandatory to specify the lib after the referring object. Usually libs are built in a way to avoid picking up too much unused code, sometimes it's unavoidable. And sometimes there is superfluous code in the provided object files: There -gc-sections may help, which is yet experimental, but it exists. Using inline and/or c++ may also yield WEAK symbols, which amiga-gcc does support. That stuff is also cleaned up by specifying -gc-sections. Last edited by bebbo; 13 May 2022 at 10:12. Reason: typo

ciVic Registered User Join Date: Oct 2013 Location: Germany Posts: 39	dirent.h with ixemul I'm trying to compile a recent rsync with GCC 6.5. It seems there is a problem with ixemul and dirent.h. During configure of rsync the test for dirent.h fails so in the end DIR is not defined. I would expect that dirent.h is available when using ixemul (by not giving -noixemul and any -mcrt), as can be seen in the ixemul repo. However, in a simple test I get: Code: sh-3.2$ cat de.c #include <dirent.h> sh-3.2$ m68k-amigaos-gcc de.c -c In file included from /opt/amiga/m68k-amigaos/sys-include/dirent.h:7:0, from de.c:1: /opt/amiga/m68k-amigaos/sys-include/sys/dirent.h:10:2: error: #error "<dirent.h> not supported" #error "<dirent.h> not supported" ^~~~~ This is obviously not the file from ixemul? It seems to be newlib: Code: sh-3.2$ grep -rnw "<dirent.h> not supported" amiga-gcc amiga-gcc/projects/newlib-cygwin/newlib/libc/include/sys/dirent.h:10:#error "<dirent.h> not supported" sh-3.2$ Last edited by ciVic; 11 September 2022 at 17:55.

bebbo bye Join Date: Jun 2016 Location: Some / Where Posts: 680	Find here updated binaries for gcc on AmigaOS: https://franke.ms/download/gcc68.lha All these programs are compiled with -Os -noixemul -m68040 -ffast-math -fomit-frame-pointer -resident32 and can be made resident now, maybe this gains some speed, maybe not. On WinUAE there is no difference if the programs are resident, and resident does not count the invokations properly /shrug. I omitted some files, which are duplicates, so copy: Code: c++ to g++, m68k-amigaos-c++ and m68k-amigaos-g++ gcc to m68k-amigaos-gcc-6.5.0b m68k-amigaos-ld to ld Assign GCC: to the install folder and add GCC:bin to the path. The headers and libs can be taken from the "normal" amiga-gcc stuff. Use a sufficient stack size - I'm using 100k. The first invokation of gcc fails on my system... since it can't invoke cc1. All further attempts succeed...

BSzili old chunk of coal Join Date: Nov 2011 Location: Hungary Posts: 1,289	I can't seem to print floating point numbers with printf. This is the floattest.c program: Code: #include <stdio.h> int main(void) { printf("%f\n", 0.1); return 0; } I build it with the following command: Code: m68k-amigaos-gcc -O2 -ffast-math -save-temps -fomit-frame-pointer -noixemul -m68060 -m68881 -lm -Wl,-Map=floattest.map -o floattest floattest.c I also uploaded the executable I built and the source files: http://bszili.morphos.me/stuff/floattest.zip It it just prints "%f" instead of the actual float value, so the format string is probably not recognized. Do I have to link it with another library or the argument order in the command is wrong? I updated to the latest version of the toolchain before testing.
