Building GCC 3.2.3 for mips

["SARAVANAP" <SARAVANAP at infosys dot com>]

Hi,

   I'm trying to build a GCC cross compiler for MIPS 32-bit and 64-bit platforms. I'm having problems in building the bootstrap compiler for "mips3" ISA. The compiler (xgcc) itself is getting built properly. But I guess, building gcc library is failing. The assembler does not like the assembly code generated by compiler.

   Binutils used: 2.13.2.1

   The error output is given below.

   I tried compiling a simple (test.c) program using the xgcc. I got the same result.

[embtools@hoopa gcc-3.2.3-compile]$ /data/tools/gcc-3.2.3-compile/gcc/xgcc -mips3  test.c

/home/embtools/tmp/ccRh1Pdw.s:20: Error: illegal operands `addiu'

   The assembly code that is failing is given below.

<...>
19:        lui     $1,%hi(%neg(%gp_rel(main)))
20:        addiu   $1,$1,%lo(%neg(%gp_rel(main)))

    Any help will be greatly appreciated.

thanks,
