2016-10-10Always support float128 on ia64 (PR target/77586).Joseph Myers2-3/+9
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).

2016-09-08Correct libgcc complex multiply excess precision handling (PR libgcc/77519).Joseph Myers2-4/+9
libgcc complex multiply is meant to eliminate excess precision from certain internal values by forcing them to memory in exactly those cases where the type has excess precision. But in https://gcc.gnu.org/ml/gcc-patches/2014-09/msg01894.html I accidentally inverted the logic so that values get forced to memory in exactly the cases where it's not needed. (This is a pessimization in the no-excess-precision case, in principle could lead to bad results depending on code generation in the excess-precision case. Note: I do not have a test demonstrating bad results.) Bootstrapped with no regressions on x86_64-pc-linux-gnu.

2016-08-26Always support float128 on x86.Joseph Myers2-12/+10
In <https://gcc.gnu.org/ml/gcc-bugs/2016-08/msg03233.html>, Nick reported i386-elf and 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 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).

2016-07-21[ARM] Fix PR target/59833Aurelien Jarno2-3/+12
For Aurelien Jarno <aurelien@aurel32.net> On ARM soft-float, the float to double conversion doesn't convert a sNaN to qNaN as the IEEE Std 754 standard mandates: "Under default exception handling, any operation signaling an invalid operation exception and for which a floating-point result is to be delivered shall deliver a quiet NaN." Given the soft float ARM code ignores exceptions and always provides a result, a float to double conversion of a signaling NaN should return a quiet NaN. Fix this in extendsfdf2. gcc/ChangeLog: PR target/59833 * config/arm/ieee754-df.S (extendsfdf2): Convert sNaN to qNaN. gcc/testsuite/ChangeLog: * gcc.dg/pr59833.c: New testcase. From-SVN: r238584
