mips linux glibc-2.3.3 build - Assembler errors in rtld.c

Hi,

glibc-2.2.3 build on mips linux breaks with following assembler errors:

This is now fixed in libc CVS.

Also, you might have to pass -fno-unit-at-a-time to gcc 3.4. (at least glibc 2.3.2 requires it).

Which is also fixed in the CVS. ;-)

So that inline mess is also gone? Find... Or is that about a different thing?

Could you please elaborate? What current glibc does is adding
-fno-unit-at-a-time where appropriate.

Some weeks ago, I had a build error (gcc+glibc head) which was because of some function being first forced to be inline, then it's address was taken... Didn't work :-)

I merged the patch int the URL you gave. It worked. Thanks.

(But now I am getting a linker error. I will post it seperately.)
