Jonathan Wakely a12c16de52 Fix location of invocable check for unique_ptr deleter
The deleter only needs to be invocable when the unique_ptr destructor
and reset member function are instantiated. In other contexts it might
not be possible to pass unique_ptr<T, D>::pointer to the deleter, if
that requires a derived-to-base conversion from T* and T is incomplete.

	* include/bits/unique_ptr.h (__uniq_ptr_impl): Remove static assertion
	checking invocable condition.
	(unique_ptr::~unique_ptr, unique_ptr::reset): Restore static assertion
	here, where types must be complete. Pass pointer to deleter as an
	rvalue.
	* testsuite/20_util/unique_ptr/requirements/incomplete.cc: New test.

Kyrylo Tkachov 6902e3a01d Fix gcc.dg/warn-abs-1.c for arm and aarch64-none-elf
This new test has some difficulties on the fabsl function.
On arm this is because we don't support the _Float128 type which the test uses.
This is handled in the patch by requiring a float128 target selector.

On aarch64-none-elf, a Newlib target, it fails because fabsl is not available.
long double support is known to be incomplete in newlib, and the fabsl function is not available
for targets where long double is larger than a double.
Therefore this patch skips the test on such targets.


	* gcc.dg/warn-abs-1.c: Require float128 target.
	Skip if large_long_double newlib target.

Kyrylo Tkachov 0dce552628 [AArch64][committed] Fix gcc.target/aarch64/spellcheck_1.c and spellcheck_4.c
These two tests started failing after commit r264335 that adjusted the cutoff point at which the diagnostic suggestions machinery decides a suggestion is meaningful.
For these tests it means we no longer suggest anything as an alternative to "armv8-a-typo" as an "arch=" pargma value. We do still list the valid options, we just don't prefer one particular value over the others.

When I first wrote this test it wasn't with a particular architecture suggestion in mind, but rather to test that the suggestion machinery is being sanely invoked.
So this patch changes the dg-message check to treat the "did you mean...?" hunk as optional (in case the heuristics in the suggestions machinery change again).

With this patch the two tests PASS again on aarch64. 

    * gcc.target/aarch64/spellcheck_1.c:
    Make architecture suggestion optional.
    * gcc.target/aarch64/spellcheck_4.c:
    Likewise.

Kyrylo Tkachov 92cb1fbc27 [AArch64][testsuite][committed] Fix gcc.target/aarch64/combine_bfxil.c for -mabi=ilp32
As described in https://gcc.gnu.org/ml/gcc-patches/2018-09/msg00963.html this test generates UXTW instructions with -mabi=ilp32
because the foo* functions take pointers and store results into them. In ILP32 the callee clears the top bits with a UXTW.
This trips the scan-assembler-not UXTW test that checks that the zero_extend form of the BFXIL pattern is used, which it is.

This patch avoids this problem by not passing pointers to the results, but instead using global variables for which the foo* functions
will synthesise the address using ADRP, avoiding the UXTW instructions.

With this patch the test PASSes fully with -mabi=ilp32 and still PASSes on LP64.

	* gcc.target/aarch64/combine_bfxil.c: Avoid passing pointers to
	functions.

David Malcolm 07f8790583 Fix overeager spelling corrections (PR c/82967)
This patch tunes class best_match's cutoff for rejecting meaningless
spelling suggestions.

Previously, we allowed an edit distance of up to half of the length of the
longer of the goal string and closest candidate strings, rounded down.

With this patch, we now allow only up to a third - with some tuning of
rounding (and for very short strings), to ensure that:
(a) everything that worked before still works (with the removal of a
couple of cases that shouldn't), and that
(b) the new threshold is always at least as conservative as the old
threshold and thus shouldn't offer new nonsensical suggestions (with
the possible exception of cases where transposition has helped; see
r261521 aka Damerau-Levenshtein; PR other/69968).

In particular, all of the bogus suggestions from PR c/82967 are now
no longer offered.

Bring in https://golang.org/cl/135297 from the gc repository to fix a
    GCC bug report.
    
    Original CL description:
    
        The GNU assembler for ARM treats @ as a comment character, so section
        types must be written using % instead.

Ian Lance Taylor 2a7ba9243e compiler: don't use address of temporary for deferred delete
This CL corrects the handling of a deferred delete in a loop, to not
    use a temporary whose value will, at deferred execution time, wind up
    being the last value in the loop.
    
    The test for this is TestDeferDeleteSlow in the 1.11 runtime package.

Kyrylo Tkachov 1b1dfddf2c [AArch64][committed] Fix gcc.target/aarch64/combine_bfi_1.c
This test started failing because some of the functions in the combine dump that it scans uses a different pattern to match the same instruction: insv_regsi rather than aarch64_bfi.
The code generation is still the same.
The patch changes the scan to look for the actual instruction we want in the assembly.

This fixes the test.
Committing to trunk as obvious.

     rather than pattern name in combine dump.
