| Subject: [PATCH] Differentiate between a bss TLS initialized symbol. |
| |
| Back-port from https://github.com/foss-for-synopsys-dwc-arc-processors/gcc/commit/366cc86e4f8ff6f00f0b731dc6f78d22c7ac9e0a |
| |
| This patch fixes "undefined reference to .tdata" observed in many autobuilder |
| results for ARC. |
| |
| Once the next release of ARC GNU tools happens this patch must be removed from |
| Buildroot. |
