+Subject: [PATCH] or1k: Only define TARGET_HAVE_TLS when HAVE_AS_TLS
|
|
|
+
|
|
|
+This was found when testing buildroot with linuxthreads enabled. In
|
|
|
+this case, the build passes --disable-tls to the toolchain during
|
|
|
+configuration. After building the OpenRISC toolchain it was still
|
|
|
+generating TLS code sequences and causing linker failures such as:
|
|
|
+
|
|
|
+ ..../or1k-buildroot-linux-uclibc-gcc -o gpsd-3.24/gpsctl .... -lusb-1.0 -lm -lrt -lnsl
|
|
|
+ ..../ld: ..../sysroot/usr/lib/libusb-1.0.so: undefined reference to `__tls_get_addr'
|
|
|
+
|
|
|
+This patch fixes this by disabling tls for the OpenRISC target when requested
|
|
|
+via --disable-tls.
