    • PR libstdc++/90314 fix non-equivalent declarations of std::swap · 315f8b5f 
      In order to use the _GLIBCXX_NOEXCEPT_IF macro for an expression
containing commas I enclosed it in parentheses, so the preprocessor
wouldn't treat it as two arguments to the function-like macro. Clang
gives an error because now the noexcept-specifier noexcept((C)) is not
equivalent to the noexcept(C) one on the declaration of swap in
<type_traits>.

Instead of requiring extra parentheses around the expression, redefine
_GLIBCXX_NOEXCEPT_IF as a variadic macro (even though supporting that in
C++98 is a GNU extension).

	PR libstdc++/90314
	* include/bits/c++config (_GLIBCXX_NOEXCEPT_IF): Use variadic macro.
	* include/bits/move.h (swap): Remove extra parentheses.

    • rs6000: Make debug regnums independent of internal ones · fc9613c6 
      Where we use "internal GCC register numbers" in debug info, that
defines an ABI, so we cannot change those numbers.  But we want to
change the internal numbers, and sometimes we do that without
remembering this gotcha anyway; so let's make everything independent
of the internal numbers.

For those registers that are not recognised here (we still have MQ for
example, but also the GCC-internal frame pointer and arg pointer
registers), this just returns the internal register number.  This is a
bit worrying: that number could be the same as that for a register we
validly want to have in debug info.  I first had a gcc_unreachable ()
for that, but this does now work because dwarf2cfi calls
rs6000_dbx_register_number for every internal register.  Then I just
returned 0 for the internal regs, but that causes various regression
tests to fail.  So now I return the internal register number again,
as it was before; but this needs to be fixed.


	* config/rs6000/rs6000.c (rs6000_dbx_register_number): Do not use
	the internal register number, for any "real" register.

    • rs6000: Debug regnums for TM registers · f58bd252 
      Since GCC 8, we have output incorrect numbers for the transactional
memory registers.

Also, we didn't output the correct DWARF register numbers for those.
The number for sprN is 100+N.

This fixes both these issues.


	* config/rs6000/rs6000.c (rs6000_dbx_register_number): Return the
	correct numbers for TFHAR, TFIAR, TEXASR.

triggered with the RISC-V lp64 multilib in a GCC build configured with 
`--enable-multilib --enable-languages=all --target=riscv64-linux-gnu'. 
This is due to unconditional explicit use of F extension instructions 
within inline assembly, to access IEEE exception flags.  The use of 
these instructions is not allowed when building for a soft-float ABI.

Correct the problem by wrapping said inline assembly into a conditional 
such that if `D_SoftFloat' is true, then reads from IEEE exception flags 
return 0 and writes are ignored instead, complementing r270522 
("libphobos: Add D support for RISC-V Linux"), which is an updated 
version of <https://gcc.gnu.org/ml/gcc-patches/2019-04/msg00325.html>, 
where the problematic code has originated from.
