* [include] Add macro DISABLE_COPY_AND_ASSIGNqiyao2017-09-152-0/+31
| | | | | | | | | | | | | | | | | | | | | We have many classes that copy cotr and assignment operator are deleted in different projects, gcc, gdb and gold. So this patch adds a macro to do this, and replace these existing mechanical code with macro DISABLE_COPY_AND_ASSIGN. The patch was posted in gdb-patches, https://sourceware.org/ml/gdb-patches/2017-07/msg00254.html but we think it is better to put this macro in include/ansidecl.h so that other projects can use it too. include: 2017-09-15 Yao Qi <yao.qi@linaro.org> Pedro Alves <palves@redhat.com> * ansidecl.h (DISABLE_COPY_AND_ASSIGN): New macro. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@252823 138bc75d-0d04-0410-961f-82ee72b054a4

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously VECTOR_CST_NELTS (t) read the number of elements from TYPE_VECTOR_SUBPARTS (TREE_TYPE (t)). There were two ways of handling this with variable TYPE_VECTOR_SUBPARTS: either forcibly convert the number to a constant (which is doable) or store the number directly in the VECTOR_CST. The latter seemed better, since it involves less pointer chasing and since the tree_node u field is otherwise unused for VECTOR_CST. It would still be easy to switch to the former in future if we need to free up the field for someting else. The patch also changes various bits of VECTOR_CST code to use VECTOR_CST_NELTS instead of TYPE_VECTOR_SUBPARTS when iterating over VECTOR_CST_ELTs. Also, when the two are checked for equality, the patch prefers to read VECTOR_CST_NELTS (which must be constant) and check against TYPE_VECTOR_SUBPARTS, instead of the other way around. 2017-09-14 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * tree-core.h (tree_base::u): Add an "nelts" field.

CL 37661 changed the gc compiler such that the select statement simply returns an integer which is then used as the argument for a switch. Since gccgo already worked that way, this just adjusts the switch code to look like the gc switch code by removing the explicit case index expression and calculating it from the order of calls to selectsend, selectrecv, and selectdefault.

We were erroneously permitting a conversion from a normal pointer to a notinheap unsafe.Pointer, which is useless since unsafe.Pointer is not marked notinheap. Correct the test to permit a conversion from unsafe.Pointer to a notinheap pointer, which is the same test that the gc compiler uses. The test case for this is in the 1.9 runtime package.
