package/gcc: backport arm acle bugfix 81497

Browse Source 
The compiler g++ reports an error when the header arm_acle.h is
included from version 7.

This patch backports the bugfix upstreamed [1] for gcc-7 and gcc-8.

Subject: [PATCH] [arm] PR target/81497: Fix arm_acle.h for C++
MIME-Version: 1.0
Content-Type: text/plain; charset=utf-8
Content-Transfer-Encoding: 8bit
When trying to compile something with arm_acle.h using G++ we get a number of nasty errors:
arm_acle.h:48:49: error: invalid conversion from ‘const void*’ to ‘const int*’ [-fpermissive]
return __builtin_arm_ldc (__coproc, __CRd, __p);
This is because the intrinsics that are supposed to be void return the "result" of their builtin,
which is void. C lets that slide but C++ complains.
After fixing that we run into further errors:
arm_acle.h:48:46: error: invalid conversion from 'const void*' to 'const int*' [-fpermissive]
return __builtin_arm_ldc (__coproc, __CRd, __p);
^~~
Because the pointer arguments in these intrinsics are void pointers but the builtin
expects int pointers. So this patch introduces new qualifiers for void pointers and their
const-qualified versions and uses that in the specification of these intrinsics.
This gives us the opportunity of creating an arm subdirectory in g++.dg and inaugurates it
with the first arm-specific C++ tests (in that directory).
