Hello,
The first patch allows to use general ARC TLS macro for ARCv3 and allows to build tests for ARCv3. The second patch contains fix for the TLS_GD macro.

Pavel Kozlov (1): arc: fix TLS_GD macro, bad clobber list
Sergey Matyukevich (1): arc: use existing tls macros for ARCv3 32-bit CPUs

Move function call outside the inline asm code to simplify a clobber list.
The patch fixes tests tst-tls7 and tst-tls8 on ARCv3, they didn't pass because cc was not in clobber list and bad code was generated. The compiler didn't take in account changes of CPU Condition flags.
