As a final note on this bug, the core dumps disappear on mips-sgi-irix if I start from the beginning with 64bit code, i.e. mips64-sgi-irix.
By setting -mabi=64 in CFLAGS, longs become 8 bytes, and bugs disappear. No need for my hack of tricking gmp into using 32 bit mips asm. This solves the package.conf bug, the __decodeFloat bug and the gmp div bug that mips people have encountered.
After edting by hand the configure script, to accept the "mips64-sgi-irix" platform, I got the next failure gcc -x c GHC/IOBase.hc -o GHC/IOBase.o -c -O -DNO_REGS -DUSE_MINIINTERPRETER -D__GLASGOW_HASKELL__=600 -O -DNO_REGS -DUSE_MINIINTERPRETER -I/usr/users/eden/scratch/6.0.1/ghc-6.0.1/ghc/includes -I/usr/users/eden/scratch/6.0.1/ghc-6.0.1/libraries/base/include -I/usr/users/eden/scratch/6.0.1/ghc-6.0.1/libraries/unix/include -mabi=64 -I. `echo | sed 's/^$/-DSTOLEN_X86_REGS=4/'` gcc -x c GHC/Int.hc -o GHC/Int.o -c -O -DNO_REGS -DUSE_MINIINTERPRETER -D__GLASGOW_HASKELL__=600 -O -DNO_REGS -DUSE_MINIINTERPRETER -I/usr/users/eden/scratch/6.0.1/ghc-6.0.1/ghc/includes -I/usr/users/eden/scratch/6.0.1/ghc-6.0.1/libraries/base/include -I/usr/users/eden/scratch/6.0.1/ghc-6.0.1/libraries/unix/include -mabi=64 -I. `echo | sed 's/^$/-DSTOLEN_X86_REGS=4/'` GHC/Int.hc: In function `sbsy_ret': GHC/Int.hc:3093: `int64ToIntegerzh_fast' undeclared (first use in this function) GHC/Int.hc:3093: (Each undeclared identifier is reported only once GHC/Int.hc:3093: for each function it appears in.)

So we'll see how far we get using 64 bits right from the start on this funny Irix thing.
