Add new architechture in gcc build error

Add new architechture in gcc build error

[daniel tian]

[-- Attachment #1: Type: text/plain, Size: 4041 bytes --]

Hi,
   I have already finished CPU port named RICE.  The previous version
I did is on gcc 4.0.2. it can be compiled.  Now I wanna move it to
v4.3.0.  I added the config script just as the CRX architechture.
   But when run the configure,

export TARGET=rice-elf
export PREFIX=/usr/local/cross/$TARGET
export PATH=$PATH:$PREFIX/bin

rm -fr build-gcc
mkdir build-gcc

cd build-gcc
../rice-gcc-4.3.0/configure --target=$TARGET --prefix=$PREFIX
--enable-languages=c  --without-headers --with-newlib --with-gnu-as
--with-gnu-ld --disable-multilib --disable-libssp

make all 2>&1 | tee build.log



but the error occurred like the following:

I add the script in those files just like the CRX architechture:

I check the config.log, here is error:

the config.log file is attached in the mail.

Binutils is installed into the computer(Of course it has ported onto RICE).


I search the gcc maillist, but I can't find some useful information.
Can anybody give me some advice.

Thank you very much!

You've got to get in there with gdb and find out why compute_frame_pointer_to_fb_displacement()
is erroring.  There's no way to avoid this.

Thank you.
But I don't know how. I mean which execute file, even I can't find the
"conftest.c" file.

Sorry for asking this simple question.

Re: Add new architechture in gcc build error

[sumanth]

Hi ,
     Follow this wiki  " http://gcc.gnu.org/wiki/DebuggingGCC" to know 
how to debug gcc.
    
   As far as I know  compute_frame_pointer_to_fb_displacement is the 
displacement between your
    frame pointer and the frame base ( mostly stack pointer's location 
after your prologue code - depends on your architecture).
    You need to tell dwarf how much you are displacing your frame in 
order to fit in your variables and stack pushed registers of a specific 
function.
     The above mentioned explanation is my perception ( I am novice too 
in gcc). However  your error might not  be related to it.
 
The only way you can resolve your issue is by debugging gcc as per the 
link I mentioned.
Feel free to ask , if any clarifications required.
  
Thanks,
Sumanth G

Thank you very much.
I will look into it.  I need to figure out where the "conftest.c" is.
I mean I know how to use the gdb or insight.
But I wonder which execute file I need to run, is the "cc1"?
and to compile the "conftest.c" file with "cc1"?

Any advice is appreciated.

Does everyone port the gcc to a new target alway encounter this
problem, or just the luck hits on me?

Thanks.

It happens to everyone.

Thanks.
So it is the simplest program.  I will find the problem..

Thank you again.

This is the error.

This is the failed program.

That should give you all you need to recreate the problem.

Now you need to fire up the debugger and take a look at the failure.  It
has something to do with unexpected behaviour in your backend register
elimination.  It's pretty hard to say anything else about it with the
information you provided.

Re: Add new architechture in gcc build error

[daniel tian]

Thank you. I fixed the error. it caused by macro:
#define ELIMINABLE_REGS \
{\

 {ARG_POINTER_REGNUM,	     FRAME_POINTER_REGNUM}, \
 {ARG_POINTER_REGNUM,	     STACK_POINTER_REGNUM}, \
 {FRAME_POINTER_REGNUM,	     STACK_POINTER_REGNUM} \
}

because everytime when gcc check the frame_pointer_need, if it is
false, aim eliminated register is SP.
But in the former array, gcc still got FP. So error accurred.

Now it is OK with the following:
#define ELIMINABLE_REGS \
{\
 {ARG_POINTER_REGNUM,	     STACK_POINTER_REGNUM}, \
 {ARG_POINTER_REGNUM,	     FRAME_POINTER_REGNUM}, \
 {FRAME_POINTER_REGNUM,	     STACK_POINTER_REGNUM} \
}
just exchange the former two elements.

So thanks for your guys.
