Yes, I am simply building the toolchain and running single testcase by hand
using:

DEJAGNU=~/ixos/linux2.6/linux/3rdParty/crosstool/crosstool-0.28-rc19/boards/
master.exp
PATH=~/ixos/linux2.6/linux/3rdParty/crosstool/crosstool-0.28-rc19/result/dej
agnu/bin/:$PATH runtest --tool=gcc --target=powerpc-750-linux-gnu -v -v -v
-v -a execute.exp=struct-ret-1.c

Or compiling using "~toolDir/powerpc-750-linux-gnu-gcc [flags]
struct-ret-1.c" and then transferring it to the 
target.

Thanks for your time and help.

Then maybe it's due to one of these files in patches/gcc-3.3.3:

  gcc-3.3.2-arm-softfloat.patch
  pr11608.patch
  pr12009.patch
  pr12010.patch
  pr13250-fix.patch
  pr13260-fix-3.3.3.patch
  sh-lib1funcs_sizeAndType.patch
  sh-pic-set_fpscr-gcc-3.3.2.patch

Can you try removing them, and test whether that fixes the problem?

Also, I'm assuming you're simply building the toolchain, then compiling a
simple testcase by hand, rather than running the whole testsuite. Can you
give me the simple command you're using to compile the individual test? Then
I could help narrow down the problem further here, maybe.
