Well, the Horrible Hack does seem to work for me. Attached is a diff, including a fix for setjmp.S too. stmw/lmw only save the low 32 bits so can't really be used, and stmd/lmd aren't available. -- Alan Modra IBM OzLabs - Linux Technology Centre -------------- next part -------------- diff -urpN klibc-0.173/MCONFIG klibc/MCONFIG --- klibc-0.173/MCONFIG 2004-07-02 09:09:19.000000000 +0930 +++ kli...

Sadly the latest optimization broke completely everything. The asm code isn't gas compliant. the libFLAC linker script has a typo, disabling the asm optimization and/or altivec won't let a correct build anyway. Instant fixes for the asm stuff: sed -i -e"s:;:\#:" on the lpc_asm.s to load address instead of addis+ori you could use lis and la and PLEASE use the @l(register)

I have updated the klibc patchset based on feedback received. In particular, the patchset has been reorganized so as not to break git-bisect. Additionally, this updates the patch base to 2.6.17-git12 (d38b69689c349f35502b92e20dafb30c62d49d63) and klibc 1.4.8; the main difference on the klibc side is removal of obsolete code.
