2018-12-07[AArch64][2/2] Add sve_width -moverride tunableKyrylo Tkachov4-0/+52
On top of the previous patch that implements TARGET_ESTIMATED_POLY_VALUE and adds an sve_width tuning field to the CPU structs, this patch implements an -moverride knob to adjust this sve_width field to allow for experimentation. Again, reminder that this only has an effect when compiling for VLA-SVE that is, without msve-vector-bits=<foo>. This just adjusts tuning heuristics in the compiler,, like profitability thresholds for vectorised versioned loops, and others. It can be used, for example like -moverride=sve_width=256 to set the sve_width tuning field to 256. Widths outside of the accepted SVE widths [128 - 2048] are rejected as you'd expect. * config/aarch64/aarch64.c (aarch64_tuning_override_functions): Add sve_width entry.

2018-12-07[AArch64][1/2] Implement TARGET_ESTIMATED_POLY_VALUEKyrylo Tkachov4-0/+57
The hook TARGET_ESTIMATED_POLY_VALUE allows a target to give an estimate for a poly_int run-time value. It is used exclusively in tuning decisions, things like estimated loop iterations, probabilities etc. It is not relied on for correctness. If we know the SVE width implemented in hardware we can make more more informed decisions in the implementation of TARGET_ESTIMATED_POLY_VALUE, even when compiling for VLA vectorisation. This patch adds an sve_width field to our tuning structs and sets it for the current CPU tunings. A new value is introduced to the aarch64_sve_vector_bits_enum enum that indicates that SVE is not available: SVE_NOT_IMPLEMENTED. I set it to the same value as SVE_SCALABLE so that parts of the aarch64 backend that follow the pattern: if (vector_width == SVE_SCALABLE) do_vla_friendly_action () else assume_specific_width_for_correctness () continue to work without change, but the CPU tuning structs can use a more appropriate moniker for indicating the absence of SVE. This sets sve_width to SVE_NOT_IMPLEMENTED for all cores. I aim to add an -moverride switch in the next patch that allows a power user to experiment with different values of it for investigations. * config/aarch64/aarch64-opts.h (aarch64_sve_vector_bits_enum): Add SVE_NOT_IMPLEMENTED value. * config/aarch64/aarch64-protos.h (struct tune_params): Add sve_width field. * config/aarch64/aarch64.c (generic_tunings,cortexa35_tunings, cortexa53_tunings, cortexa57_tunings, cortexa72_tunings, cortexa73_tunings, exynosm1_tunings, thunderx_tunings, thunderx_tunings, tsv110_tunings, xgene1_tunings, qdf24xx_tunings, saphira_tunings, thunderx2t99_tunings, emag_tunings): Specify sve_width.

2018-12-06[PR86747] tsubst friend tpl ctxt before looking it up for dupesAlexandre Oliva4-1/+18
When a member template is redeclared as a friend, we enter the context of the member before looking it up, and then we check that the decls are compatible. However, when the member template references template types of the enclosing context, say an enclosing template class, the compare fails because the friend decl is already tsubsted, whereas the looked up name isn't. The problem is that the enclosing context is taken from the friend declaration before tsubsting it, so we look up in the context of the generic template instead of that of the tsubsted one we're specializing. The solution is to tsubst the enclosing context when it's a non-namespace scope. for gcc/cp/ChangeLog PR c++/86747 * pt.c (tsubst_friend_class): Enter tsubsted class context. for gcc/testsuite/ChangeLog PR c++/86747 * g++.dg/pr86747.C: New.

2018-12-06[PR86397] resolve nondependent noexcept specs early in C++1[14]Alexandre Oliva5-4/+21
build_noexcept_spec refrained from resolving nondependent noexcept expressions when they were not part of the function types (C++ 11 and 14). This caused problems during mangling: canonical_eh_spec, when called on the template function type, would find an unresolved but not explicitly deferred expression, and nothrow_spec_p would reject it. We could relax the mangling logic to skip canonical_eh_spec, but since -Wnoexcept-type warns when mangling function names that change as noexcept specs become part of types and of mangling in C++17, and the test at mangling time may give incorrect results if the spec is not resolved, we might as well keep things simple and resolve nondependent noexcept specs sooner rather than later. This is what this patch does. for gcc/cp/ChangeLog PR c++/86397 * except.c (build_noexcept_spec): Resolve nondependent expressions. for gcc/testsuite/ChangeLog PR c++/86397 * g++.dg/cpp0x/pr86397-1.C: New. * g++.dg/cpp0x/pr86397-2.C: New.

2018-12-06avoid null ptr deref in cselib_record_setsAlexandre Oliva2-0/+6
Jeff Law tells me h8300-elf fails gcc.c-torture/compile/pr49029.c with -O2 -g -mint32 -mh. This patch fixes it. The problem is that strict low part handling in cselib_record_sets assumes src_elt is not NULL. That src_elt is taken from a strict low part set, but it won't always have a src_elt to begin with. In this case, it's because src is a volatile MEM; we don't record values for those. Although we could fix the problem by testing for a NULL src_elt before creating the zero extends corresponding to strict low part sets of formerly const0_rtx REGs, there's no point in recording the additional set that we won't be able to use anyway. We could still record that the whole register has a zero-extend of the value stored in the narrower-mode strict low part of the register, but is that of any use? I guess not, but if we find otherwise, we can change that later. for gcc/ChangeLog * cselib.c (cselib_record_sets): Skip strict low part sets with NULL src_elt. From-SVN: r266873
2018-12-06[rs6000] Enable x86-compat vector intrinsics testingPaul A. Clarke7-100/+24
The testsuite tests for the compatibility implementations of x86 vector intrinsics for "powerpc" had been inadvertently made to PASS without actually running the test code. This patch removes the code which kept the tests from running the actual test code. 2018-12-06 Paul A.

2018-12-06[rs6000] Fix x86-compat vector intrinsics testcases for BE, 32bitPaul A. Clarke14-80/+235
Fix general endian issues found in the test cases for thecompatibility implementations of the x86 vector intrinsics. (The tests had been inadvertently made to PASS without actually running the test code. A later patch fixes this issue.) Additionally, a new <smmintrin.h> is added, as some of the APIs therein are now used by the test cases. It is _not_ a complete implementation of the SSE4 interfaces, only the few "extract" interfaces uses by the tests. 2018-12-06 Paul A.
