[uclibc-ng-devel] [PATCH 2/2] arc: fix TLS_GD macro, bad clobber list

From: Pavel Kozlov <pavel.kozlov(a)synopsys.com> 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.
