-Subject: [PATCH] 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).
-
- PR target/81497
- * config/arm/arm-builtins.c (arm_type_qualifiers): Add
- qualifier_void_pointer and qualifier_const_void_pointer.
- (arm_ldc_qualifiers, arm_stc_qualifiers): Use the above.
- (arm_init_builtins): Handle the above.
- * config/arm/arm_acle.h (__arm_cdp, __arm_ldc, __arm_ldcl, __arm_stc,
- __arm_stcl, __arm_mcr, __arm_cdp2, __arm_ldc2, __arm_ldcl2, __arm_stc2,
- __arm_stcl2,__arm_mcr2, __arm_mcrr, __arm_mcrr2): Remove return for
- void intrinsics.
-
- * g++.target/arm/arm.exp: New file.
- * g++.target/arm/pr81497.C: Likewise.
