2021-04-20libstdc++: Refactor/cleanup of C++20 atomic wait implementationThomas Rodgers19-710/+978
This is a substantial rewrite of the atomic wait/notify (and timed wait counterparts) implementation. The previous __platform_wait looped on EINTR however this behavior is not required by the standard. A new _GLIBCXX_HAVE_PLATFORM_WAIT macro now controls whether wait/notify are implemented using a platform specific primitive or with a platform agnostic mutex/condvar. This patch only supplies a definition for linux futexes. A future update could add support __ulock_wait/wake on Darwin, for instance. The members of __waiters were lifted to a new base class. The members are now arranged such that overall sizeof(__waiter_pool_base) fits in two cache lines (on platforms with at least 64 byte cache lines). The definition will also use destructive_interference_size for this if it is available. The __waiters type is now specific to untimed waits, and is renamed to __waiter_pool. Timed waits have a corresponding __timed_waiter_pool type. Much of the code has been moved from the previous __atomic_wait() free function to the __waiter_base template and a __waiter derived type is provided to implement the un-timed wait operations. A similar change has been made to the timed wait implementation. The __atomic_spin code has been extended to take a spin policy which is invoked after the initial busy wait loop. The default policy is to return from the spin. The timed wait code adds a timed backoff spinning policy. The code from <thread> which implements this_thread::sleep_for, sleep_until has been moved to a new <bits/std_thread_sleep.h> header which allows the thread sleep code to be consumed without pulling in the whole of <thread>. The entry points into the wait/notify code have been restructured to support either - * Testing the current value of the atomic stored at the given address and waiting on a notification. * Applying a predicate to determine if the wait was satisfied. The entry points were renamed to make it clear that the wait and wake operations operate on addresses. The first variant takes the expected value and a function which returns the current value that should be used in comparison operations, these operations are named with a _v suffix (e.g. 'value'). All atomic<_Tp> wait/notify operations use the first variant. Barriers, latches and semaphores use the predicate variant. This change also centralizes what it means to compare values for the purposes of atomic<T>::wait rather than scattering through individual predicates. This change also centralizes the repetitive code which adjusts for different user supplied clocks (this should be moved elsewhere and all such adjustments should use a common implementation). This change also removes the hashing of the pointer and uses the pointer value directly for indexing into the waiters table. libstdc++-v3/ChangeLog: * include/Makefile.am: Add new <bits/this_thread_sleep.h> header. * include/Makefile.in: Regenerate. * include/bits/this_thread_sleep.h: New file. * include/bits/atomic_base.h: Adjust all calls to __atomic_wait/__atomic_notify for new call signatures. * include/bits/atomic_timed_wait.h: Extensive rewrite. * include/bits/atomic_wait.h: Likewise. * include/bits/semaphore_base.h: Adjust all calls to __atomic_wait/__atomic_notify for new call signatures. * include/std/atomic: Likewise. * include/std/barrier: Likewise. * include/std/latch: Likewise. * include/std/semaphore: Likewise. * include/std/thread (this_thread::sleep_for) (this_thread::sleep_until): Move to new header. * testsuite/29_atomics/atomic/wait_notify/bool.cc: Simplify test. * testsuite/29_atomics/atomic/wait_notify/generic.cc: Likewise. * testsuite/29_atomics/atomic/wait_notify/pointers.cc: Likewise. * testsuite/29_atomics/atomic_flag/wait_notify/1.cc: Likewise. * testsuite/29_atomics/atomic_float/wait_notify.cc: Likewise. * testsuite/29_atomics/atomic_integral/wait_notify.cc: Likewise. * testsuite/29_atomics/atomic_ref/wait_notify.cc: Likewise.

2021-04-20libstdc++: Implement P2259R1 changes [PR95983]Patrick Palka4-107/+412
This implements the wording changes of P2259R1 "Repairing input range adaptors and counted_iterator", which resolves LWG 3283, 3289 and 3408. The wording changes are relatively straightforward, but they require some boilerplate to implement: the changes to make a type alias "conditionally present" in some iterator class are realized by defining a base class template and an appropriately constrained partial specialization thereof that contains the type alias, and having the iterator class derive from this base class. Sometimes the relevant condition depend on members from the iterator class, but because a class is incomplete when instantiating its bases, the constraints on the partial specialization can't use anything from the iterator class. This patch works around this by hoisting these members out to the enclosing scope (e.g. transform_view::_Iterator::_Base is hoisted out to transform_view::_Base so that transform_view::__iter_cat can use it). This patch also implements the proposed resolution of LWG 3291 to rename iota_view::iterator_category to iota_view::iterator_concept, which was previously problematic due to LWG 3408. libstdc++-v3/ChangeLog: PR libstdc++/95983 * include/bits/stl_iterator.h (__detail::__move_iter_cat): Define.

2021-04-20libstdc++: Update ppc64le baseline_symbols.txtJakub Jelinek2-2/+256
> Tested on powerpc64{,le}-linux now (-m32/-m64 on be) and while the first > patch works fine, the second one unfortunately doesn't on either be or le, > so more work is needed there. Here are the needed changes to make it work. For symbols with _LDBL_ substring in version name we already have code to ignore those if no such symbols appear (but it is slightly incorrect, see below). So, this patch does the same thing for symbol versions with _IEEE128_ substring. The previously incorrectly handled case is that in addition to FUNC:_ZNKSt17__gnu_cxx_ieee1287num_getIcSt19istreambuf_iteratorIcSt11char_traitsIcEEE14_M_extract_intImEES4_S4_S4_RSt8ios_baseRSt12_Ios_IostateRT_@@GLIBCXX_IEEE128_3.4.29 or OBJECT:12:_ZTSu9__ieee128@@CXXABI_IEEE128_1.3.13 cases we also have the OBJECT:0:CXXABI_IEEE128_1.3.13 OBJECT:0:GLIBCXX_IEEE128_3.4.29 cases, which have empty version_name and the name is in that case the symbol version. Those need to be ignored too. 2021-04-20 Jakub Jelinek <jakub@redhat.com> * testsuite/util/testsuite_abi.cc (compare_symbols): If any symbol versions with _IEEE128_ substring are found, set ieee_version_found to true.

2021-04-17testsuite: Enable zero-scratch-regs-{8,9,10,11}.c on s390*Stefan Schulze Frielinghaus5-4/+69
On s390* the only missing part for the mentioned testcases was a load of a double floating-point zero via a move (in particular for quite old machines) which was added in commit 46c47420a5fefd4d9d02b0db347235dd74e20fb2. Common code implementation is sufficient in order to clear volatile GPRs, FPRs, and VRs. Access registers a0 and a1 are nonvolatile and not cleared. Therefore, target hook TARGET_ZERO_CALL_USED_REGS is not implemented for s390*. Added a target specific test in order to ensure that all call clobbered GPRs, FPRs, and VRs are zeroed and all call saved registers are kept. gcc/testsuite/ChangeLog: * c-c++-common/zero-scratch-regs-8.c: Enable on s390*. * c-c++-common/zero-scratch-regs-9.c: Likewise. * c-c++-common/zero-scratch-regs-10.c: Likewise. * c-c++-common/zero-scratch-regs-11.c: Likewise. * gcc.target/s390/zero-scratch-regs-1.c: New test.

As mentioned in the PR, SIGSTKSZ is no longer a compile time constant in glibc 2.34 and later, so static const uptr kAltStackSize = SIGSTKSZ * 4; needs dynamic initialization, but is used by a function called indirectly from .preinit_array and therefore before the variable is constructed. This results in using 0 size instead and all asan instrumented programs die with: ==91==ERROR: AddressSanitizer failed to allocate 0x0 (0) bytes of SetAlternateSignalStack (error code: 22) Here is a cherry-pick from upstream to fix this. 2021-04-17 Jakub Jelinek <jakub@redhat.com> PR sanitizer/100114 * sanitizer_common/sanitizer_posix_libcdep.cpp: Cherry-pick llvm-project revisions 82150606fb11d28813ae6da1101f5bda638165fe and b93629dd335ffee2fc4b9b619bf86c3f9e6b0023.

The previous change to this testcase missed the fact that the data may be accessed via an anchor, depending on the optimization level, leading to false failures. This patch restricts matching to upper16:lower16 followed by non-spaces, followed by +4 (in f4) or +320 (in f5). Using '.*' instead of '[^ \]' would match accross the whole assembly file, which is not what we want, hence the limitation with spaces. 2021-04-16 Christophe Lyon <christophe.lyon@linaro.org> gcc/testsuite/ PR target/96770 * gcc.target/arm/pure-code/pr96770.c: Fix scan-assembler-times with movt/movw.
2021-04-16aarch64: Don't emit -Wpsabi note when ABI was never affected [PR91710]Jakub Jelinek2-9/+30
As the following testcase shows, we emit a -Wpsabi note about argument passing change since GCC 9, but in reality the ABI didn't change. The alignment is 8 bits in GCC < 9 and 32 bits in GCC >= 9 and the aarch64_function_arg_alignment returns in that case: return MIN (MAX (alignment, PARM_BOUNDARY), STACK_BOUNDARY); so when both the old and new alignment are smaller or equal to PARM_BOUNDARY (or both are larger than STACK_BOUNDARY, just in theory), even when the new one is bigger, it doesn't change the argument passing. So, the following patch changes aarch64_function_arg_alignment to tell the callers the exact old alignmentm so that they can test it if needed. The other aarch64_function_arg_alignment callers either check the alignment for equality against 16-byte alignment (when old alignment was smaller than that and the new one is 16-byte, we want to emit -Wpsabi in all the cases) or the va_arg case which I think is ok now too. 2021-04-16 Jakub Jelinek <jakub@redhat.com> PR target/91710 * config/aarch64/aarch64.c (aarch64_function_arg_alignment): Change abi_break argument from bool * to unsigned *, store there the pre-GCC 9 alignment.

2021-04-16intl: Add --enable-host-shared support [PR100096]Jakub Jelinek3-2/+20
As mentioned in the PR, building gcc with jit enabled and --enable-host-shared doesn't work on NetBSD/i?86, as libgccjit.so.0 has text relocations. The r0-125846-g459260ecf8b420b029601a664cdb21c185268ecb changes added --enable-host-shared support to various libraries, but didn't add it to intl/ subdirectory; on Linux it isn't really needed, because all: all-no all-no: #nothing but on other OSes intl/libintl.a is built.

2021-04-16SVE: Fix wrong sve predicate split (PR100048)Tamar Christina4-5/+45
The attached testcase generates the following paradoxical subregs when creating the predicates. (insn 22 21 23 2 (set (reg:VNx8BI 100) (subreg:VNx8BI (reg:VNx2BI 103) 0)) (expr_list:REG_EQUAL (const_vector:VNx8BI [ (const_int 1 [0x1]) (const_int 0 [0]) (const_int 1 [0x1]) (const_int 0 [0]) repeated x5 ]) (nil))) and (insn 15 14 16 2 (set (reg:VNx8BI 96) (subreg:VNx8BI (reg:VNx2BI 99) 0)) (expr_list:REG_EQUAL (const_vector:VNx8BI [ (const_int 1 [0x1]) (const_int 0 [0]) repeated x7 ]) (nil))) This causes CSE to incorrectly think that the two predicates are equal because some of the significant bits get ignored due to the subreg. The attached patch instead makes it so it always looks at all 16-bits of the predicate, but in turn means we need to generate a TRN that matches the expected result mode. In effect in RTL we keep the mode as VNx16BI but during codegen re-interpret them as the mode the predicate instruction wanted: (insn 10 9 11 2 (set (reg:VNx8BI 96) (subreg:VNx8BI (reg:VNx16BI 99) 0)) (expr_list:REG_EQUAL (const_vector:VNx8BI [ (const_int 1 [0x1]) (const_int 0 [0]) repeated x7 ]) (nil))) Which needed correction to the TRN pattern. A new TRN1_CONV unspec is introduced which allows one to keep the arguments as VNx16BI but encode the instruction as a type of the last operand. (insn 9 8 10 2 (set (reg:VNx16BI 99) (unspec:VNx16BI [ (reg:VNx16BI 97) (reg:VNx16BI 98) (reg:VNx2BI 100) ] UNSPEC_TRN1_CONV)) (nil)) This allows us remove all the paradoxical subregs and end up with (insn 16 15 17 2 (set (reg:VNx8BI 101) (subreg:VNx8BI (reg:VNx16BI 104) 0)) (expr_list:REG_EQUAL (const_vector:VNx8BI [ (const_int 1 [0x1]) (const_int 0 [0]) (const_int 1 [0x1]) (const_int 0 [0]) repeated x5 ]) (nil))) gcc/ChangeLog: PR target/100048 * config/aarch64/aarch64-sve.md (@aarch64_sve_trn1_conv<mode>): New. * config/aarch64/aarch64.c (aarch64_expand_sve_const_pred_trn): Use new TRN optab. * config/aarch64/iterators.md (UNSPEC_TRN1_CONV): New. gcc/testsuite/ChangeLog: PR target/100048 * gcc.target/aarch64/sve/pr100048.c: New test.
