Hi, I noticed that klibc started crashing on 64-bit MIPS and in my quest to fix the bug I got a bit carried away and fixed a few other things as well. Here are various miscellaneous MIPS patches, although the first patch is the important one. Thanks, James *** BLURB HERE *** James Cowgill (5): mips64: compile with -mno-abicalls mips: use -Ttext-segment when linking shared library mips/mips64: simplify crt0 code mips: don't save floating point registers in setjmp / longjmp mips64: remove __unused from __jmp_buf usr/include/arch/mips/klibc/archsetjmp.h | 14 -- usr/...

I can't seem to find the right set of commands to enable me to do perform a regression with cluster-adjusted standard-errors. There seems to be nothing in the archives about this -- so this thread could help generate some useful content. I've searched everywhere. Can anyone point me to the right set of commands? An example would be most helpful as well. Bo [[alternative HTML version

James Cowgill dixit: >klibc does this when it saves all the FPU registers in its setjmp Hm, shouldn?t klibc not use the FPU at all? AFAIK it was unsupported to use it. bye, //mirabilos -- <hecker> cool ein Ada Lovelace Google-Doodle. aber zum 197. Geburtstag? H?tten die nicht noch 3 Jahre warten k?n...
