Max Filippov 2a26adf1d8 xtensa: don't use unwind-dw2-fde-dip with elf targets 
Define LIB2ADDEH_XTENSA_UNWIND_DW2_FDE to unwind-dw2-fde.c in
xtensa/t-elf and to unwind-dw2-fde-dip.c in xtensa/t-linux and use
LIB2ADDEH_XTENSA_UNWIND_DW2_FDE in LIB2ADDEH definition.

This fixes build for elf target with windowed xtensa core that currently
breaks with the following error message:
    
  unwind-dw2-fde-dip.c:36:40: fatal error: elf.h: No such file or directory

Joseph Myers 73f01cca84 Always support float128 on ia64 (PR target/77586). 
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).

Joseph Myers d758aeb5ff Correct libgcc complex multiply excess precision handling (PR libgcc/77519). 
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.  Code size
went down on x86_64 as expected; old sizes:

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.

Aurelien Jarno a1b01d3403 [ARM] Fix PR target/59833 
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.
