For interoperability with C++ EH, the alignment should match, otherwise
D may not be able to intercept exceptions thrown from C++.
libphobos/ChangeLog:
* libdruntime/gcc/unwind/generic.d (__aligned__): Define.
(_Unwind_Exception): Align struct to __aligned__.
(cherry picked from commit efa5449a09)
Fixes a segfault seen on Darwin when a GC scan is ran after a thread has
been destroyed. As the global emutlsArrays hash still has a reference
to the array itself, and tries to iterate all elements.
Setting the length to zero frees all allocated elements in the array,
and ensures that it is skipped when the _d_emutls_scan is called.
libphobos/ChangeLog:
* libdruntime/gcc/emutls.d (emutlsDestroyThread): Clear the per-thread
TLS array, don't call free().
(cherry picked from commit 796b7cbac3)
As of macOS 11, libunwind now requires more stack space than 16k, so
default to a larger stack size. This is only applied to X86 as the
PAGESIZE is still 4k, however on AArch64 it is 16k.
libphobos/ChangeLog:
* libdruntime/core/thread.d (defaultStackPages): New constant.
(Fiber.this): Set stack size to be a multiple of defaultStackPages.
(cherry picked from commit 651a542822)
Fixes a EXC_BAD_ACCESS issue seen on Darwin when the libphobos DSO gets
unloaded. Based on reading libgcc's emutls implementation, as it
doesn't call __gthread_key_delete directly, neither should libphobos.
libphobos/ChangeLog:
* libdruntime/gcc/emutls.d (emutlsDestroyThread): Don't remove entry
from global array.
(_d_emutls_destroy): Don't call __gthread_key_delete.
(cherry picked from commit 910d2b4b75)
The change in major version (and the increment from Darwin19 to 20)
caused libtool tests to fail which resulted in incorrect build settings
for shared libraries.
We take this opportunity to sort out the shared undefined symbols state
rather than propagating the current unsound behaviour into a new rev.
This change means that we default to the case that missing symbols are
considered an error, and if one wants to allow this intentionally, the
confiuration for that case should be set appropriately.
Three existing cases need undefined dynamic lookup:
libitm, where there is already a configuration mechanism to add the
flags.
libcc1, where we add simple configuration to add the flags for Darwin.
libsanitizer, where we can add to the existing extra flags.

The dynamic section on MIPS is read-only, but this was not properly

that linked to the shared libphobos library.

etc., due to the use of the MIPS II LDC1 and SDC1 hardware instructions
for FP register load and store operations. Instead use the L.D and S.D
generic assembly instructions, which are strict aliases for the LDC1 and
SDC1 instructions respectively and produce identical machine code where
the assembly for the MIPS II or a higher ISA has been requested, however
they become assembly macros and expand to compatible sequences of LWC1
and SWC1 hardware instructions where the assembly for the MIPS I ISA is
in effect.

The last change to the bindings removed the st_pad3 field from the wrong

`--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>,
