2020-07-01c++: Expose cloning form predicatesNathan Sidwell2-34/+41
A further adjustment of the function cloning. Rather than have copy_fndecl_with_name deduce whether a particular cdtor needs a vtt_parm and/or has inherited parms to drop, pass that information in from the caller. In particular build_cdtor_clones knows when its building the particular cdtors that might need these. On the modules branch I need to clone cdtors before the underlying class information is necessarily complete. There build_cdtor_clones is externally callable to facilitate that. gcc/cp/ * class.c (copy_fndecl_with_name): Add additional predicate args, do not deduce them locally. (copy_operator_fn): Adjust copy_fndecl_with_name call. (build_clone): Add vtt and inherited predicate args. Pass through to copy_fndecl_with_name call.

2020-07-01tree-optimization/95839 - teach SLP vectorization about vector inputsRichard Biener2-15/+124
This teaches SLP analysis about vector typed externals that are fed into the SLP operations via lane extracting BIT_FIELD_REFs. It shows that there's currently no good representation for vector code on the SLP side so I went a half way and represent such vector externals uses always using a SLP permutation node with a single external SLP child which has a non-standard representation of no scalar defs but only a vector def. That works best for shielding the rest of the vectorizer from it. 2020-06-26 Richard Biener <rguenther@suse.de> PR tree-optimization/95839 * tree-vect-slp.c (vect_slp_tree_uniform_p): Pre-existing vectors are not uniform.

2020-06-30aarch64: Treat GNU and Advanced SIMD vectors as distinct [PR92789, PR95726]Richard Sandiford3-18/+77
PR95726 is about template look-up for things like: foo<float vecf __attribute__((vector_size(16)))> foo<float32x4_t> The immediate cause of the problem is that the hash function usually returns different hashes for these types, yet the equality function thinks they are equal. This then raises the question of how the types are supposed to be treated. I think the answer is that the GNU vector type should be treated as distinct from float32x4_t, not least because the two types mangle differently. However, each type should implicitly convert to the other. This would mean that, as far as the PR is concerned, the hashing function is right to (sometimes) treat the types differently and the equality function is wrong to treat them as the same. The most obvious way to enforce the type difference is to use a target-specific type attribute. That on its own is enough to fix the PR. The difficulty is deciding whether the knock-on effects are acceptable. One obvious effect is that GCC then rejects: typedef float vecf __attribute__((vector_size(16))); vecf x; float32x4_t &z = x; on the basis that the types are no longer reference-compatible. I think that's again the correct behaviour, and consistent with current Clang. A trickier question is whether: vecf x; float32x4_t y; … c ? x : y … should be valid, and if so, what its type should be [PR92789]. As explained in the comment in the testcase, GCC and Clang both accepted this, but GCC chose the “then” type while Clang chose the “else” type. This can lead to different mangling for (probably artificial) corner cases, as seen for “sel1” and “sel2” in the testcase. Adding the attribute makes GCC reject the conditional expression as ambiguous. I think that too is the correct behaviour, for the reasons described in the testcase. However, it does seem to have the potential to break existing code. It looks like aarch64_comp_type_attributes is missing cases for the SVE attributes, but I'll handle that in a separate patch. 2020-06-30 Richard Sandiford <richard.sandiford@arm.com> gcc/ PR target/92789 PR target/95726 * config/aarch64/aarch64.c (aarch64_attribute_table): Add "Advanced SIMD type".

2020-06-30c++: Tweak function cloning namesNathan Sidwell5-14/+22
On the modules branch I need to expose an intermediate step of the function cloning, but before that it'd be nice to rationalize the names somewhat, now that we also use that API for copying the equality operator. Jason's recent patch caused me some pain by altering the same code. I can only blame myself for not pushing some bits sooner. Anyway, this patch makes the newly renamed copy_fndecl_with_name static, and adds a wrapper copy_operator_fn, that takes an operator code. The cdtor cloning functions are renamed to explicitly note they expect cdtors. A followup patch will move some of the logic from copy_fndecl_with_name to build_cdtor_clones. gcc/cp/ * cp-tree.h (copy_fndecl_with_name): Rename to ... (copy_operatorn_fn): ... this.

2020-06-30[testsuite] Replace fragile 'scan-assembler' with 'scan-offload-rtl' in ↵Thomas Schwinge5-10/+10
'libgomp.oacc-c-c++-common/pr85381*.c' These test cases use directives similar to: /* { dg-additional-options "-save-temps" } */ /* { dg-final { scan-assembler-times "bar.sync" 2 } } */ This expects to scan the PTX offloading compilation assembler code (not host code!), expecting that nvptx offloading code assembly is produced after the host code, and thus overwrites the latter file. (Yes, that's certainly ugly/fragile...) ..., and this broke with recent commit 1dedc12d186a110854537e1279b4e6c29f2df35a "revamp dump and aux output names" plus fix-up commit commit efc16503ca10bc0e934e0bace5777500e4dc757a "handle dumpbase in offloading, adjust testsuite" (short summary: file names changed), so let's finally make that robust. libgomp/ * testsuite/libgomp.oacc-c-c++-common/pr85381-2.c: Replace fragile 'scan-assembler' with 'scan-offload-rtl'. * testsuite/libgomp.oacc-c-c++-common/pr85381-3.c: Likewise. * testsuite/libgomp.oacc-c-c++-common/pr85381-4.c: Likewise. * testsuite/libgomp.oacc-c-c++-common/pr85381-5.c: Likewise. * testsuite/libgomp.oacc-c-c++-common/pr85381.c: Likewise.

2020-06-30arm: Warn if IRQ handler is not compiled with -mgeneral-regs-only [PR ↵Christophe Lyon11-3/+141
target/94743] The interrupt attribute does not guarantee that the FP registers are saved, which can result in problems difficult to debug. Saving the FP registers and status registers can be a large penalty, so it's probably not desirable to do that all the time. If the handler calls other functions, we'd likely need to save all of them, for lack of knowledge of which registers they actually clobber. This is even more obscure for the end-user when the compiler inserts calls to helper functions such as memcpy (some multilibs do use FP registers to speed it up). In the PR, we discussed adding routines in libgcc to save the FP context and saving only locally-clobbered FP registers, but this seems to be too much work for the purpose, given that in general such handlers try to avoid this kind of penalty. I suspect we would also want new attributes to instruct the compiler that saving the FP context is not needed. In the mean time, emit a warning to suggest re-compiling with -mgeneral-regs-only. Note that this can lead to errors if the code uses floating-point and -mfloat-abi=hard, eg: argument of type 'double' not permitted with -mgeneral-regs-only This can be troublesome for the user, but at least this would make him aware of the latent issue. The patch adds several testcases: - pr94734-1-hard.c checks that a warning is emitted when using -mfloat-abi=hard. Function IRQ_HDLR_Test can make implicit calls to runtime floating-point routines (or direct use of FP instructions), IRQ_HDLR_Test2 doesn't. We emit a warning in both cases, though. - pr94734-1-softfp.c: same as above wih -mfloat-abi=softfp. - pr94734-1-soft.c checks that no warning is emitted when using -mfloat-abi=soft when the same code as above. - pr94734-2.c checks that no warning is emitted when using -mgeneral-regs-only. - pr94734-3.c checks that no warning is emitted when using -mgeneral-regs-only even using float-point data. 2020-06-30 Christophe Lyon <christophe.lyon@linaro.org> PR target/94743 gcc/ * config/arm/arm.c (arm_handle_isr_attribute): Warn if -mgeneral-regs-only is not used. gcc/testsuite/ * gcc.misc-tests/arm-isr.c: Add -mgeneral-regs-only. * gcc.target/arm/empty_fiq_handler.c: Add -mgeneral-regs-only. * gcc.target/arm/interrupt-1.c: Add -mgeneral-regs-only. * gcc.target/arm/interrupt-2.c: Add -mgeneral-regs-only. * gcc.target/arm/pr70830.c: Add -mgeneral-regs-only. * gcc.target/arm/pr94743-1-hard.c: New test. * gcc.target/arm/pr94743-1-soft.c: New test. * gcc.target/arm/pr94743-1-softfp.c: New test. * gcc.target/arm/pr94743-2.c: New test. * gcc.target/arm/pr94743-3.c: New test.

2020-06-30Use CHARACTER(kind) string for calculating the type hash.Thomas Koenig4-3/+52
This regression came about because of a change in the way types are displayed in error messages. The character representation is also used to calculate the hashes for our types, so this patch restores the old behavior if we are indeed calculating a hash. The test case also checks for the specific hash value because changing that would be an ABI change, which we should not be doing unintentionally. gcc/fortran/ChangeLog: 2020-06-30 Thomas Koenig <tkoenig@gcc.gnu.org> PR fortran/95355 * gfortran.h (gfc_typename): Add optional argument for_hash. * misc.c (gfc_typename): When for_hash is true, just retur CHARACTER(kind). * class.c (gfc_intrinsic_hash_value): Call gfc_typename with for_hash = true.

2020-06-30coroutines: Collect the function body rewrite code.Iain Sandoe1-329/+213
The standard describes a rewrite of the body of the user-authored function (which wraps it in a try-catch block and provides the initial and final suspend expressions). The exact arrangement of this was still in flux right up until the DIS and as a consequence was a bit of a moving target. The net result was a fragmented implementation of the parts of the rewrite which is now impeding progress in fixing other issues. This patch collates the rewrite action into a single function and carries this out earlier. gcc/cp/ChangeLog: * coroutines.cc (expand_one_await_expression): Remove code dealing with initial suspend. (build_actor_fn): Remove code special-casing initial and final suspend. Handle the final suspend and marking of the coroutine as done. (coro_rewrite_function_body): New. (bind_expr_find_in_subtree): Remove. (coro_body_contains_bind_expr_p): Remove. (morph_fn_to_coro): Split the rewrite of the original function into coro_rewrite_function_body and call it.
