Bug #: 55835
Summary: [TileGX] libgcc doesn't build.
Classification: Unclassified
Product: gcc
Version: 4.7.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libgcc
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: gcc.5.saskw...@spamgourmet.com
gcc/config/tilegx/linux.h in the 4.7.2 source wants to #include <arch/icache.h>
but there is no icache.h anywhere in the source distribution.
I grabbed the arch directory from Tilera's MDE distribution and plopped it into
libgcc's include path and now get this error when trying to build libgcc for
the TileGX:
# If this is the top-level multilib, build all the other
# multilibs.

I've built GCC and binutils already for the TileGX with the following commands:
$ ../binutils-2.23/configure --target=tilegx-redhat-linux --prefix=$PREFIX
--disable-nls
$ make -j9 all
$ make install
and, for GCC...
$ ../gcc-4.7.2/configure --target=tilegx-redhat-linux --prefix=$PREFIX
--disable-nls --without-headers
$ make -j9 all-gcc
$ make install-gcc
In the GCC build directory, I then ran
$ make all-target-libgcc
to get the above error.
