Hello,
I've recently started adding Blackfin support to Crosstool-NG. On
Blackfin, there are typically 3 toolchains available :
* bfin-elf, a bare-metal toolchain using newlib
* bfin-uclinux, a Linux toolchain that generates flat binaries (no
shared libaries)
* bfin-linux-uclibc, a Linux toolchain that generates FDPIC ELF
binaries (shared libraries are possible)
I've focused on the latest one for the moment, and I've reached the
point where I can compile a small Hello World application, both dynamic
and static and run it on the target. I haven't tried more complicated
examples at the moment.
The attached patches implement the needed modifications:
* 1838, Add basic support for the Blackfin architecture
* 1839, Fix the uClibc clean-up-O_CLOEXEC-handling patch
* 1840, Re-enable the FD_PIC ELF configuration option
* 1841, Add uClibc support for Blackfin
* 1842, Add Blackfin-related uClibc patch
* 1843, Add Blackfin sample
However, in addition to these patches, I had to make a very ugly
modification :

else

}
This is because Crosstool-NG assumes that when the architecture has
no-mmu, the kernel part of the tuple must be "uclinux". However, in the
case of Blackfin toolchains, it seems that the tradition is
bfin-uclinux for FLAT toolchains and bfin-linux-uclibc for FDPIC
toolchains. Therefore, I had to hack this part of Crosstool-NG code.
Obviously, this is not the right way to do it, and that's why I'm
requesting for your comments on how to implement this properly.
On a side note, when is Crosstool-NG switching to git ? When you're
used to Git with all the other open-source projects, switching to
Mercurial just for Crosstool-NG is kind of painful.
Thanks!
Thomas

Add uClibc support for Blackfin
For uClibc, the name of the Blackfin architecture is 'bfin'. Actually,
the naming of the architecture is quite messy: for toolchain tuples
and uClibc, it's bfin, but for the kernel, it's blackfin. We've
arbitraly choosen to name it "blackfin" in Crosstool-NG.
