Has anybody here before buiding gcc-3.4 cvs version using --with-cpu=iwmmxt option? I'm doing this based on dan's crosstool-0.27. Finally I found out the bootstrap gcc has problem to build glibc-2.3.2 while processing glibc/locale/ld-callob.c it will say: /tmp/ccWwfxuD.s: Assembler messages: /tmp/ccWwfxuD.s:6430: Error: bad immediate value for offset (4128) /tmp/ccWwfxuD.s:6435: Error: bad immediate value for offset (4112)
while using option --with-cpu=xscale, it will be ok. So I think this is related to iwmmxt specific codes in gcc-3.4-cvs.
Who succeeded to build iwmmxt gcc-3.4, pls raise your hand ok? thanks!
gcc-3.4-20040225 builds fine for me here, though I haven't tried testing the resulting toolchain. Here is a patch to crosstool to add the needed files.
You might also need to give crosstool an arm-iwmmxt.config for the kernel, and change arm-iwmmxt.dat to reference that instead of arm.config. If you find this is the case, please send me the kernel config file you end up using.
