You might just say: 'Yeah! crosstool-NG's got its own repo!". Unfortunately, that's because the previous repo got damaged beyond repair and I had no backup. That means I'm putting backups in place in the afternoon. That also means we've lost history... :-(

I believe this flushes my current patches to make glibc work on SH. Issues:
|
|
- MIPS pread functions have some wackiness in them for the MIPS calling
|
|
conventions, which align long longs to even register pairs; it appears
|
|
that SH does not do this. This fixes pread64/pwrite64.
|
|
- st_ino is _NOT_ 64-bit in the latest SH kernel trees, or at least it
|
|
wasn't when I checked in April. --enable-kernel=2.4.x breaks terribly
|
|
without this patch; the errors are along the lines of "version GLIBC_2.3
|
|
not found", because that's the first consequence of a messed up inode
|
|
field - ld.so compares by inodes at some point.
