GCC uses TLS common for both public common / BSS and local common / BSS. This patch reverts to use .comm directive to allocate TLS common / BSS. This also changes the priority of section selection to use BSS before data section. gcc/ChangeLog: * config/rs6000/rs6000.c (rs6000_xcoff_select_section): Select TLS BSS before TLS data. * config/rs6000/xcoff.h (ASM_OUTPUT_TLS_COMMON): Use .comm. gcc/testsuite/ChangeLog: * g++.dg/gomp/tls-5.C: Expect tbss failure on AIX.
