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.
