The __cpu_indicator_init and __cpu_model symbols are not safe to use from shared libgcc_s.so from ifunc resolvers, so since gcc-6, only the definitions from static libgcc.a are used, however the symbols are kept in libgcc_s as well for backward compatibility (with appropriate symbol version).

2016-10-10Always support float128 on ia64 (PR target/77586).jsm28
Bug 77586, and previously <https://gcc.gnu.org/ml/gcc-bugs/2016-08/msg03233.html>, reports ia64-elf failing to build because of float128_type_node being NULL, but being used by the back end for __float128. The global float128_type_node is only available conditionally, if target hooks indicate TFmode is not only available as a scalar mode and of the right format, but also supported in libgcc. The back-end support, however, expects the type always to be available for __float128 even if the libgcc support is missing. Although a target-specific node could be restored in the case where libgcc support is missing, it seems better to address the missing libgcc support. Thus, this patch enables TFmode soft-fp in libgcc globally for all ia64 targets. Support for XFmode in libgcc (that is, for libgcc2.c XFmode functions, not soft-fp) is also enabled for all ia64 targets so that ia64 no longer needs to define the TARGET_LIBGCC_FLOATING_MODE_SUPPORTED_P hook. I've confirmed that ia64-elf builds cc1 with this patch and it passes -fself-test. I have not otherwise tested the patch. It's plausible that ia64-elf and ia64-freebsd might work as-is, but ia64-vms probably needs further changes, by someone familiar with VMS shared libraries, to implement an equivalent of ia64/t-softfp-compat in that case (avoiding conflicts between __divtf3 from soft-fp and the old alias for __divxf3).

The back-end support, however, expects the type always to be available for __float128 even if the libgcc support is missing. Although a target-specific node could be restored in the case where libgcc support is missing, it seems better to address the missing libgcc support. Thus, this patch enables TFmode soft-fp in libgcc globally for all x86 targets - the only special cases needed being for targets that use soft-fp for SFmode and DFmode, one of which already had the support for TFmode as well (so I based the i[34567]86-*-rtems* configuration on that present for i[34567]86-*-elfiamcu). The i386 implementation of TARGET_LIBGCC_FLOATING_MODE_SUPPORTED_P is then removed as no longer needed. I can provide such a patch for ia64 if useful, but am not in a position to test it (and while I'm reasonably confident that enabling this support would be right for ia64-elf and ia64-freebsd, I've no real idea if enabling libgcc support for TFmode, with or without also enabling it for XFmode, would be safe for ia64-vms). Bootstrapped with no regressions on x86_64-pc-linux-gnu. gcc: * config/i386/i386.c (ix86_libgcc_floating_mode_supported_p) (TARGET_LIBGCC_FLOATING_MODE_SUPPORTED_P): Remove. * config/i386/i386elf.h (IX86_MAYBE_NO_LIBGCC_TFMODE): Likewise. * config/i386/lynx.h (IX86_MAYBE_NO_LIBGCC_TFMODE): Likewise. * config/i386/netbsd-elf.h (IX86_MAYBE_NO_LIBGCC_TFMODE): Likewise. * config/i386/netbsd64.h (IX86_MAYBE_NO_LIBGCC_TFMODE): Likewise. * config/i386/nto.h (IX86_MAYBE_NO_LIBGCC_TFMODE): Likewise. * config/i386/openbsd.h (IX86_MAYBE_NO_LIBGCC_TFMODE): Likewise. * config/i386/rtemself.h (IX86_NO_LIBGCC_TFMODE): Likewise. * config/i386/vxworks.h (IX86_MAYBE_NO_LIBGCC_TFMODE): Likewise. libgcc: * config.host (i[34567]86-*-* | x86_64-*-*): Enable TFmode soft-fp where not already enabled. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@239775 138bc75d-0d04-0410-961f-82ee72b054a4
