Thank you, Adam, I did not think of that posibility.
I will give it a shot.

I have to create a toolchain with hard fpu support for
arm1176's VFPv2.
That's because, by looking at the ARM
documentation I don't see how I can perform
mathematic operations on the FPU (like FABSx, FADDx
without using these mnemonics), (as it is the case for fpu load/store operations), so as far as see, I have to build a toolchain that recognized these mnemonics.
I dont' know where to start.
Has anybody used a script like crosstools for this? I
hope by creating a new dat file with proper GCC and GLIBC argumets I could do the job myself, but I have no idea what would those arguments be or where to find them:
GCC += ?? --with-float=hard --fpu=vfpv2
--cpu=arm1176jzf ??
GLIBC += ??
Where can I find what gcc version might include
support for my hard fpu? I tried the man pages in gcc-4.1.2 and gcc-3.4.4 without success and I can't figure out where to look for this on gnu.org.
Can you point me in the right direction to use.
