Author: adrian Date: Sun Aug 14 19:04:37 2016 New Revision: 304096 URL: https://svnweb.freebsd.org/changeset/base/304096 Log: [mips] convert over =v to =r for the inline assembly. Later gcc and clang have deprecated =v (which maps to a specific temp register) and instead we should just use =r to have the assembler (hopefully!) save/restore things appropriately after choosing a register. Tested: * AR9344 SoC, with userreg support * AR9331 SoC, with no userreg support Sponsored by: Sponsored by: DARPA, AFRL (MIPS TLS user register work) Modified: head/lib/libthr/arch/mips/include/pthread_md.h Modified: head/lib/libthr/arch/mips/include/pthread_md.h ============================================================================== --- head/lib/libthr/arch/mips/include/pthread_md.h Sun Aug 14 19:03:33 2016 (r304095) +++ head/lib/libthr/arch/mips/include/pthread_md.h Sun Aug 14 19:04:37 2016 (r304096) @@ -84,7 +84,7 @@ _tcb_get(void) ".set\tmips64r2\n\t" "rdhwr\t%0, $29\n\t" ".set\tpop" - : "=v" (_rv)); + : "=r" (_rv)); /* * XXXSS See 'git show c6be4f4d2d1b71c04de5d3bbb6933ce2dbcdb317' @@ -106,7 +106,7 @@ _tcb_get(void) ".set\tmips32r2\n\t" "rdhwr\t%0, $29\n\t" ".set\tpop" - : "=v" (_rv)); + : "=r" (_rv)); /* * XXXSS See 'git show c6be4f4d2d1b71c04de5d3bbb6933ce2dbcdb317'
