OR1K tools

[Rosimildo da Silva]

Ok,
I have tried to compile the toolset under my CygWin environmnet:

  + NT 4.0 SP5
  + CygWin 1.1.2


Results:


1. Compiling the Simulator:

   + Configuration fails, if it is not done in the same directory as
     source resides. ( ./configure ... )

   + libreadline library not found. Under CygWin readline.a is 
     not installed. 
     Compiled with the version that came with insight 5.0. 
     Simulator compiled and linked OK. It seems to reach
     some error when executing 'testbench/dhry.or32'.

Here it is the output:

bash-2.04$ ./sim testbench/dhry.or32

2. Binutils

   + Do we have elf support ? It seems to support coff only now.

   + It seems to be already configured.
   
   + ./configure --target=or32 --prefix=/gcc-or32

   + compiled and installed Ok.




3. gcc

  + 'tar' utility of CygWin seems to fail to "untar" the archive.

  + I had to unse PkZip to unzip the gcc archive ( problems with
    gcc/fixincl file ).

  + GCC configured fine in the same directory as source. 
     ( ./configure --target=or32 --prefix=/gcc-or32  --with-gnu-as
--with-gnu-ld ).


  + error during compilation:
