2019-05-17PR libstdc++/85965 move is_invocable assertions againJonathan Wakely14-33/+101
This is another attempt to reduce how often the assertions are evaluated, so that code which doesn't try to use the function objects doesn't need them to be invocable. For _Rb_tree we access the _M_key_compare object directly, so can't put the assertions in an accessor function for it. However, every invocation of _M_key_compare is accompanied by a use of _S_key, so the assertions can be put in there. For _Hashtable there are member functions that are consistently used to obtain a hash code or test for equality, so the assertions can go in those members. PR libstdc++/85965 * include/bits/hashtable.h (_Hashtable::~_Hashtable()): Remove static assertions from the destructor. * include/bits/hashtable_policy.h (_Hash_code_base::_M_hash_code): Move static_assert for hash function to here.

2019-05-17compiler: use SHA1-hash for symname for long gcbits symbolsIan Lance Taylor2-10/+32
The current scheme used by the compiler for "gcbits" symbols involves generating a symbol name based on a 32-char encoding of the bits data. This scheme works well in most cases but can generate very long symbol names in rare cases. To help avoid such long symbol names, switch to a different encoding scheme based on the SHA1 digest of the payload if the symbol size would be too large. Fixes golang/go#32083.

2019-05-17re PR go/90482 (Many 32-bit Solaris/SPARC tests FAIL with SIGBUS)Ian Lance Taylor5-19/+42
PR go/90482 compiler: make value method of direct interface type takes pointer Currently, a value method of a direct interface type takes the value of the receiver, which is pointer shaped, as the first parameter. When this method is called through interface, we actually pass the interface data as a pointer. On most platforms this is ok, as the underlying calling convention is the same, except that on SPARC32, the calling convention is actually different. This CL changes the method function actually takes a pointer. The function will convert the pointer to the pointer-shaped receiver type (a no-op conversion from machine code's aspect). For a direct call, in the caller we convert the receiver to a pointer (also no-op conversion) before invoking the method. For an interface call, we pass the pointer as before. This way, it is consistent that we always pass a pointer. Hopefully this fixes SPARC32 build and https://gcc.gnu.org/PR90482.

runtime/internal/sys.Ctz32/64 and Bswap32/64 are currently implemented with compiler builtin functions. But if they are called from another package, the compiler does not know and therefore cannot turn them into compiler intrinsics. This CL makes the compiler recognize these functions and turn them into intrinsics directly, as the gc compiler does. This CL sets up a way for adding intrinsics in the compiler. More intrinsics will be added in later CLs. Also move the handling of runtime.getcallerpc/sp to the new way of generating intrinsics.

2019-05-16Replace _Equal_helper with simpler class templateJonathan Wakely2-36/+23
By defining the new helper inside _Hashtable_base it doesn't need all the template parameters to be provided, and by making it only responsible for checking a possibly-cached hash code it only has to do one thing. The caller can use the equality predicate itself instead of duplicating that in the helper template. * include/bits/hashtable_policy.h (_Equal_helper): Remove. (_Hashtable_base::_Equal_hash_code): Define new class template. (_Hashtable_base::_M_equals): Use _Equal_hash_code instead of _Equal_helper. From-SVN: r271291

2019-05-16Remove unnecessary non-const accessors in hash table basesJonathan Wakely2-36/+23
The const accessors are OK (and arguably more correct) for most callers to use. The _M_swap functions that use the non-const overloads can just directly use the _S_get members of the EBO helpers. * include/bits/hashtable_policy.h (_Hash_code_base::_M_swap): Use _S_get accessors for members in EBO helpers.
