Description Enrico Scholz 2008-02-14 06:19:39 EST
Description of problem:

Trying to build dietlibc on ppc/ppc64 fails on the first invocation of the
generated 'diet' program; there

| $ strace -f -s9999 bin-ppc/diet gcc -D__dietlibc__ -O2 -g -pipe -Wall
| ...
| execve("/usr/sbin/-D__dietlibc__", ["-D__dietlibc__", "-O2", "-g", ...

happens where i386/x86_64 platforms do

| execve("/usr/sbin/gcc", ["gcc", "-nostdlib", "-static", ..., "-D__dietlibc__",
"-O2", "-g", ...


I suspect there are problems with alloca(), but can not debug it further. Hence,
I am going to exclude ppc/ppc64 for now.


Version-Release number of selected component (if applicable):

dietlibc-0.31-1.20080212.fc9.src.rpm
gcc-4.3.0-0.7   


How reproducible:

100%

fixed; optimized string functions were buggy on big-endian.
