arm gnueabi problem with tls.

[Steve Papacharalambous <stevep at freescale dot com>]

Hi,

I'm trying to build an arm-linux-gnueabi toolchain using:

binutils-2.16.1
gcc-4.1.0
linux-2.6.16.1 kernel headers
glibc-2.4
glibc-ports-2.4

I applied the patches posted by Khem Raj to crosstool-0.42: 
http://sourceware.org/ml/crossgcc/2006-03/msg00090.html

The configure for build-glibc-startfiles fails with: "configure: error: 
compiler support for __thread is required"

If I try to compile a simple test program: "extern __thread int i;" with 
the gcc-core compiler it gives the error: "test-__thread.c:1: error: 
thread-local storage not supported for this target"

The configuration for the gcc-core compiler is:

[snip]
arm-linux-gnueabi-gcc -v
Using built-in specs.
Target: arm-linux-gnueabi
Configured with: ../gcc-4.1.0/configure --target=arm-linux-gnueabi 
--host=i686-host_pc-linux 
--prefix=/home/stevep/work/tools/tcf/glibc-2.4-work/gcc-core-prefix 
--with-local-prefix=/opt/crosstool/gcc-4.1.0-glibc-2.4/arm-linux-gnueabi/arm-linux-gnueabi 
--disable-multilib --with-newlib --disable-libunwind-exceptions 
--without-headers --disable-nls --enable-threads=posix 
--enable-symvers=gnu --enable-__cxa_atexit --enable-languages=c 
--disable-shared --with-tls --with-__thread
Thread model: posix
gcc version 4.1.0
[/snip]

I tried different configuration combinations for gcc, but it doesn't 
seem to make any differnce as I get the same error every time I try to 
compile the test program.  :-(

Is thread local storage supported for arm eabi targets in gcc-4.1.0, or 
have I configured the core compiler incorrectly?  Or is there a patch 
needed to gcc?

Best regards,

Steve
