2019-12-10[AArch64] Don't allow partial SVE modes in GPRsRichard Sandiford4-1/+40
With -msve-vector-bits=N, the payload of some partial SVE modes can be 16 bytes or smaller, which makes them small enough to fit in a pair of GPRs. We specifically don't want that, because the payload is distributed evenly across the SVE register rather than collected at one end. Marshalling it into a GPR via register operations would be expensive. 2019-12-10 Richard Sandiford <richard.sandiford@arm.com> gcc/ * config/aarch64/aarch64.c (aarch64_hard_regno_mode_ok): Don't allow SVE modes in GPRs. gcc/testsuite/ * gcc.target/aarch64/sve/mixed_size_7.c: New test.

2019-12-10[AArch64] Fix INDEX patterns for partial VNx2 modesRichard Sandiford5-4/+68
The INDEX patterns handle partial modes by choosing the container size rather than the element size, so that the number of lanes (and thus number of additions) matches the mode. This means that all VNx4 modes use .s and all VNx2 modes use .d, etc. When adding this, I'd forgotten that the choice between Wn and Xn registers would need to be updated to use the container size too. For partial VNx2s, we were using .d containers with Wn rather than Xn source registers. 2019-12-10 Richard Sandiford <richard.sandiford@arm.com> gcc/ * config/aarch64/iterators.md (vccore): New iterator. * config/aarch64/aarch64-sve.md (vec_series<mode>): Use it instead of vwcore.

2019-12-10Make dwarf2out punt for MODE_VECTOR_BOOLRichard Sandiford4-1/+37
The dwarf2 handling of vector constants currently divides the vector into a length (number of elements) and byte element size. This doesn't work well for MODE_VECTOR_BOOL, where several elements are packed into the same byte. We should probably add a way of encoding this in future, but for now the safest thing is to punt, like we already do for variable-length vectors. 2019-12-10 Richard Sandiford <richard.sandiford@arm.com> gcc/ * dwarf2out.c (loc_descriptor): Punt for MODE_VECTOR_BOOL.

2019-12-10Add missing conversion in vect_create_epilog_for_reductionRichard Sandiford2-0/+8
The direct_slp_reduc code in vect_create_epilog_for_reduction was still assuming that all types involved in a reduction are the same (up to types_compatible_p), whereas we now support differences in sign. This was causing an ICE in gcc.dg/vect/pr92324-4.c for SVE. 2019-12-10 Richard Sandiford <richard.sandiford@arm.com> gcc/ * tree-vect-loop.c (vect_create_epilog_for_reduction): When handling direct_slp_reduc, allow the PHI arguments to have a different type from the vector elements.

2019-12-10Record the loop masks needed for EXTRACT_LAST_REDUCTIONsRichard Sandiford4-2/+45
The analysis phase of vectorizable_condition wasn't recording the loop masks needed by the transform phase. This meant that the masks wouldn't be created in the (rare) case that no other statement needed them. 2019-12-10 Richard Sandiford <richard.sandiford@arm.com> gcc/ * tree-vect-stmts.c (vectorizable_condition): Record the loop masks required for extract-last reductions. gcc/testsuite/ * gcc.target/aarch64/sve/clastb_9.c: New test.

2019-12-10Fix EXTRACT_LAST_REDUCTION handling of pattern stmtsRichard Sandiford2-7/+16
Unlike most vector ops, extract-last reductions replace the original scalar code in-situ rather than adding an adjacent vector implementation. I.e.: dest_1 = COND_EXPR <...>; becomes: dest_1 = .EXTRACT_LAST (...); gcc.dg/vect/vect-cond-reduc-4.c was ICEing for SVE because we tried to replace the pattern statement in this way, rather than replacing the original scalar statement. 2019-12-10 Richard Sandiford <richard.sandiford@arm.com> gcc/ * tree-vect-stmts.c (vect_finish_replace_stmt): Always use the original scalar statement rather than a pattern statement.

gcc.dg/vect/vect-cond-reduc-5.c was ICEing for SVE because we tried to use an extract-last reduction for a chain of COND_EXPRs. Adding support for the chained case would be too invasive for stage 3 so this patch explicitly forbids it instead. I've filed PR92884 for the possible future work. 2019-12-10 Richard Sandiford <richard.sandiford@arm.com> gcc/ * tree-vect-loop.c (vectorizable_reduction): Don't use EXTRACT_LAST_REDUCTION for chained reductions.

2019-12-10Replace label_text ctor with "borrow" and "take"David Malcolm11-11/+64
libcpp's label_text class wraps a text buffer, along with a flag to determine if it "owns" the buffer. The existing ctor exposed this directly, but I found it difficult to remember the sense of flag, so this patch hides the ctor, in favor of static member functions "borrow" and "take", to make the effect on ownership explicit in the name. gcc/c-family/ChangeLog: * c-format.c (range_label_for_format_type_mismatch::get_text): Replace label_text ctor called with true with label_text::take. gcc/c/ChangeLog: * c-objc-common.c (range_label_for_type_mismatch::get_text): Replace label_text ctor calls. gcc/cp/ChangeLog: * error.c (range_label_for_type_mismatch::get_text): Replace label_text ctor calls with label_text::borrow. gcc/ChangeLog: * gcc-rich-location.c (maybe_range_label_for_tree_type_mismatch::get_text): Replace label_text ctor call with label_text::borrow. * gcc-rich-location.h (text_range_label::get_text): Replace label_text ctor called with false with label_text::borrow. libcpp/ChangeLog: * include/line-map.h (label_text::label_text): Make private.

2019-12-10diagnostic_show_locus: move initial newline to callersDavid Malcolm10-145/+148
diagnostic_show_locus adds a newline before doing anything (including the do-nothing-else case). This patch removes this initial newline, adding it to all callers of diagnostic_show_locus instead.

2019-12-09Fix libdecnumber handling of non-canonical BID significands (PR ↵Joseph Myers11-3/+184
middle-end/91226). As reported in bug 91226, the libdecnumber code used on the host to interpret DFP values in the BID encoding fails, for _Decimal64 and _Decimal128, to check for the case where a significand is too large and so specified in IEEE 754 to be a non-canonical encoding of the zero significand. This patch adds the required handling of that case, together with tests both using -O2 (testing this host code) and -O0 (testing libgcc code, which already worked before the patch); the tests also cover _Decimal32, which already had the required check. In the _Decimal128 case, where the code previously completely ignored the case where the first four bits of the combination field are 1100, 1101 or 1110, the logic for determining the correct quantum exponent in that case is also newly added by this patch, so tests are added for that as well (again, libgcc already handled it correctly when the conversion was done at runtime rather than at compile time). Bootstrapped with no regressions for x86_64-pc-linux-gnu. PR middle-end/91226 libdecnumber: * bid/bid2dpd_dpd2bid.c (_bid_to_dpd64): Handle non-canonical significands. (_bid_to_dpd128): Likewise.

2019-12-09[mid-end] Add notes to dataflow insn info when re-emitting (PR92410)Matthew Malcomson6-0/+27
In scheduling passes, notes are removed with `remove_notes` before the scheduling is done, and added back in with `reemit_notes` once the scheduling has been decided. This process leaves the notes in the RTL chain with different insn uid's than were there before. Having different UID's (larger than the previous ones) means that DF_INSN_INFO_GET(insn) will access outside of the allocated array. This has been seen in the `regstat_bb_compute_calls_crossed` function. This patch adds an assert to the `regstat_bb_compute_calls_crossed` function so that bad accesses here are caught instead of going unnoticed, and then avoids the problem. We avoid the problem by ensuring that new notes added by `reemit_notes` have an insn record given to them. This is done by adding a call to `df_insn_create_insn_record` on each note added in `reemit_notes`. `df_insn_create_insn_record` leaves this new record zeroed out, which appears to be fine for notes (e.g. `df_bb_refs_record` already does not set anything except the luid for notes, and notes have no dataflow information to record). We add the testcase that Martin found here https://gcc.gnu.org/bugzilla/show_bug.cgi?id=92410#c2 . This testcase fails with the "regstat.c" change, and then succeeds with the "haifa-sched.c" change. There is a similar problem with labels, that the `gcc_assert` catches when running regression tests in gcc.dg/fold-eqandshift-1.c and gcc.c-torture/compile/pr32482.c. This is due to the `cfg_layout_finalize` call in `bb-reorder.c` emitting new labels, and these labels not having a dataflow df_insn_info member. We solve this by manually calling `df_recompute_luids` on each basic block once this pass has finished. Testing done: Ran regression tests on aarch64-none-linux-gnu cross compiler. Bootstrapped and ran tests on aarch64-none-linux-gnu native. gcc/ChangeLog: 2019-12-09 Matthew Malcomson <matthew.malcomson@arm.com> PR middle-end/92410 * bb-reorder.c (pass_reorder_blocks::execute): Recompute dataflow luids once basic blocks have been reordered. * haifa-sched.c (reemit_notes): Create df insn record for each new note. * regstat.c (regstat_bb_compute_calls_crossed): Assert every insn has an insn record before trying to use it. gcc/testsuite/ChangeLog: 2019-12-09 Matthew Malcomson <matthew.malcomson@arm.com> PR middle-end/92410 * gcc.dg/torture/pr92410.c: New test.

2019-12-09[GCC, Vect] Fix costing for vector shiftsSudakshina Das4-1/+31
While looking at the vectorization for following example, we realized that even though vectorizable_shift function was distinguishing vector shifted by vector from vector shifted by scalar, while modelling the cost it would always add the cost of building a vector constant despite not needing it for vector shifted by scalar. This patch fixes this by using scalar_shift_arg to determine whether we need to build a vector for the second operand or not. This causes the test case below to now vectorize. gcc/ChangeLog: 2019-12-09 Sudakshina Das <sudi.das@arm.com> Richard Sandiford <richard.sandiford@arm.com> * tree-vect-stmt.c (vectorizable_shift): Condition ndts for vect_model_simple_cost call on scalar_shift_arg. gcc/testsuite/ChangeLog: 2019-12-09 Sudakshina Das <sudi.das@arm.com> * gcc.dg/vect/vect-shift-5.c: New test.
