Soft-float powerpc fails to build with current GCC mainline because of use of libc_hidden_data_def for TLS variables, resulting in a non-TLS alias being defined, to which the tls_model attribute is now copied, resulting in a warning about it being ignored. The problem here appears to be the non-TLS alias. This patch adds a hidden_tls_def macro family, corresponding to the hidden_tls_proto macros, to define TLS aliases properly in such a case, and uses it for those powerpc soft-float variables. Tested with build-many-glibcs.py compilers build for powerpc-linux-gnu soft-float. Also tested for x86_64. * include/libc-symbols.h [SHARED && !NO_HIDDEN && !__ASSEMBLER__] (__hidden_ver2): New macro. Use old definition of __hidden_ver1 with additional parameter thread. [SHARED && !NO_HIDDEN && !__ASSEMBLER__] (__hidden_ver1): Define in terms of __hidden_ver2. (hidden_tls_def): New macro. (libc_hidden_tls_def): Likewise. (rtld_hidden_tls_def): Likewise. (libm_hidden_tls_def): Likewise. (libmvec_hidden_tls_def): Likewise. (libresolv_hidden_tls_def): Likewise. (librt_hidden_tls_def): Likewise. (libdl_hidden_tls_def): Likewise.

(libutil_hidden_tls_def): Likweise. * sysdeps/powerpc/nofpu/sim-full.c (__sim_exceptions_thread): Use libc_hidden_tls_def. (__sim_disabled_exceptions_thread): Likewise. (__sim_round_mode_thread): Likewise. |
