2020-07-14libgomp: Fix hang when profiling OpenACC programs with CUDA 9.0 nvprofKwok Cheung Yeung3-0/+129
The version of nvprof in CUDA 9.0 causes a hang when used to profile an OpenACC program. This is because it calls acc_get_device_type from a callback called during device initialization, which then attempts to acquire acc_device_lock while it is already taken, resulting in deadlock. This works around the issue by returning acc_device_none from acc_get_device_type without attempting to acquire the lock when initialization has not completed yet. 2020-07-14 Tom de Vries <tom@codesourcery.com> Cesar Philippidis <cesar@codesourcery.com> Thomas Schwinge <thomas@codesourcery.com> Kwok Cheung Yeung <kcy@codesourcery.com> libgomp/ * oacc-init.c (acc_init_state_lock, acc_init_state, acc_init_thread): New variable.

2020-07-14openmp: Adjust outer bounds of non-rect loopsJakub Jelinek1-0/+230
In loops like: #pragma omp parallel for collapse(2) for (i = -4; i < 8; i++) for (j = 3 * i; j > 2 * i; j--) for some outer loop iterations there are no inner loop iterations at all, the condition is false. In order to use Summæ Potestate to count number of iterations or to transform the logical iteration number to actual iterator values using quadratic non-equation root discovery the outer iterator range needs to be adjusted, such that the inner loop has at least one iteration for each of the outer loop iterator value in the reduced range. Sometimes this adjustment is done at the start of the range, at other times at the end. This patch implements it during the compile time number of loop computation (if all expressions are compile time constants). 2020-07-14 Jakub Jelinek <jakub@redhat.com> * omp-general.h (struct omp_for_data): Add adjn1 member. * omp-general.c (omp_extract_for_data): For non-rect loop, punt on count computing if n1, n2 or step are not INTEGER_CST earlier.

2020-07-09openmp: Optimize triangular loop logical iterator to actual iterators ↵Jakub Jelinek2-0/+170
computation using search for quadratic equation root(s) This patch implements the optimized logical to actual iterators computation for triangular loops. I have a rough implementation using integers, but this one uses floating point. There is a small problem that -fopenmp programs aren't linked with -lm, so it does it only if the hw has sqrt optab (and uses ifn rather than __builtin_sqrt because it obviously doesn't need errno handling etc.). Do you think it is ok this way, or should I use the integral computation using inlined isqrt (we have inequation of the form start >= x * t10 + t11 * (((x - 1) * x) / 2) where t10 and t11 are signed long long values and start unsigned long long, and the division by 2 actually is a problem for accuracy in some cases, so if we do it in integral, we need to do actually long long t12 = 2 * t10 - t11; unsigned long long t13 = t12 * t12 + start * 8 * t11; unsigned long long isqrt_ = isqrtull (t13); long long x = (((long long) isqrt_ - t12) / t11) >> 1; with careful overflow checking on all the computations before isqrtull (and on overflows use the fallback implementation). 2020-07-09 Jakub Jelinek <jakub@redhat.com> * omp-general.h (struct omp_for_data): Add min_inner_iterations and factor members. * omp-general.c (omp_extract_for_data): Initialize them and remember them in OMP_CLAUSE_COLLAPSE_COUNT if needed and restore from there. * omp-expand.c (expand_omp_for_init_counts): Fix up computation of counts[fd->last_nonrect] if fd->loop.n2 is INTEGER_CST.

2020-06-26c++: Change the default dialect to C++17.Marek Polacek1-1/+2
Since GCC 9, C++17 support is no longer experimental. It was too late to change the default C++ dialect to C++17 in GCC 10, but I think now it's time to pull the trigger (C++14 was made the default in GCC 6.1). We're still missing two C++17 library features, but that shouldn't stop us. See <https://gcc.gnu.org/onlinedocs/libstdc++/manual/status.html#status.iso.2017> and <https://gcc.gnu.org/projects/cxx-status.html#cxx17> for the C++17 status. I won't list all C++17 features here, but just a few heads-up: - trigraphs were removed (hardly anyone cares, unless your keyboard is missing the # key), - operator++(bool) was removed (so some tests now run in C++14 and down only), - the keyword register was removed (some legacy code might trip on this), - noexcept specification is now part of the type system and C++17 does not allow dynamic exception specifications anymore (the empty throw specification is still available, but it is deprecated), - the evaluation order rules are different in C++17, - static constexpr data members are now implicitly inline (which makes them definitions), - C++17 requires guaranteed copy elision, meaning that a copy/move constructor call might be elided completely. That means that if something relied on a constructor being instantiated via e.g. copying a function parameter, it might now fail. I'll post an update for cxx-status.html and add a new caveat to changes.html once this is in. gcc/ChangeLog: * doc/invoke.texi (C Dialect Options): Adjust -std default for C++. * doc/standards.texi (C Language): Correct the default dialect.

Automake and GNU Make both use the endif keyword, which conflicts and elicits an error for matching if/ifdef and endif.

2020-06-21aix: Add GCC64 configuration and FAT target libraries.David Edelsohn6-5/+56
This patch adds the ability to configure GCC on AIX to build as a 64 bit application and to build target libraries "FAT" libraries in both 32 bit and 64 bit mode. The patch adds makefile fragment hooks to target libraries that allows them to include target-specific rules. The target specific rules for AIX place both 32 bit and 64 bit objects and shared objects in archives at the top-level, not multilib subdirectories. The multilibs are built in subdirectories, but must be combined during the last parts of the target library build process. Because of the way that GCC bootstrap works, the libraries must be combined during the multiple stages of GCC bootstrap, not solely when installed in the final destination, so the libraries are correct at the end of each target library build stage, not solely an install recipe. gcc/ChangeLog 2020-06-21 David Edelsohn <dje.gcc@gmail.com> * config.gcc: Use t-aix64, biarch64 and default64 for cpu_is_64bit. * config/rs6000/aix72.h (ASM_SPEC): Remove aix64 option.

This upgrades the compiler to emit HSA Code Object v3 binaries. This means changing the assembler directives, and linker command line options. The gcn-run and libgomp loaders need corresponding alterations. The relocations no longer need to be fixed up manually, and the kernel symbol names have changed slightly.
