2019-10-31[AArch64] Split gcc.target/aarch64/sve/vcond_4*Richard Sandiford7-132/+299
vcond_4.c combined too much stuff into one test, so that when we needed to add XFAILs for one set of routines, we lost testing of others that used the same instructions. This patch splits it into four: vcond_4.c: The main test for selects between a vector and a scalar, with all elements having the same size. After Prathamesh's fix for PR91272, we are now guaranteed to use the conditionally-loaded vector as the "then" value and the scalar as the "else" value. vcond_4_zero.c: Like vcond_4.c, but comparing with zero. vcond_4_sel.c: Tests for selects between two scalars, with all elements having the same size. The optimisers can legitimately switch the "then" and "else" order and adjust the comparison to match. vcond_4_costly.c: Like vcnod_4.c, but with mixed element sizes. The sequences tested here will not be the preferred ones once we support mixtures of vector sizes, but it still tests an important code path. This means that vcond_4_run.c now only tests what's left in vcond_4.c, but that seems OK, since the main point was to ensure correct exception behaviour. Similarly it means that vcond_5.c only tests what's left in vcond_4.c, but that too is OK, since the point of the test was to compare the default handling of each comparison in vcond_4.c with the -fno-trapping-math equivalent. 2019-10-31 Richard Sandiford <richard.sandiford@arm.com> gcc/testsuite/ * gcc.target/aarch64/sve/vcond_4.c: Split parts out into... * gcc.target/aarch64/sve/vcond_4_costly.c, * gcc.target/aarch64/sve/vcond_4_sel.c, * gcc.target/aarch64/sve/vcond_4_zero.c: ...these new tests. * gcc.target/aarch64/sve/vcond_4_run.c: Adjust accordingly. * gcc.target/aarch64/sve/vcond_5.c: Likewise.

2019-10-31[AArch64] Split gcc.target/aarch64/sve/reduc_strict_3.cRichard Sandiford8-116/+155
This patch splits gcc.target/aarch64/sve/reduc_strict_3.c into one test per function, so that it's easier to see what each scan is matching and also so that we no longer rely on the number of times that each dump message is printed. The patch also generalises the tests to work with scalable vectors. I think the test probably predates support for variable-length loop-aware SLP. 2019-10-31 Richard Sandiford <richard.sandiford@arm.com> gcc/testsuite/ * gcc.target/aarch64/sve/reduc_strict_3.c: Split all but the first function out into... * gcc.target/aarch64/sve/reduc_strict_4.c, * gcc.target/aarch64/sve/reduc_strict_5.c, * gcc.target/aarch64/sve/reduc_strict_6.c, * gcc.target/aarch64/sve/reduc_strict_7.c, * gcc.target/aarch64/sve/reduc_strict_8.c, * gcc.target/aarch64/sve/reduc_strict_9.c: ...these new tests.

2019-10-31[AArch64] Fix build for non-default languagesRichard Sandiford2-2/+9
The SVE PCS support broke go, D and Ada because those languages don't call TARGET_INIT_BUILTINS. We therefore ended up trying to get the TYPE_MAIN_VARIANT of a null __SVBool_t. We shouldn't really need to apply TYPE_MAIN_VARIANT there anyway, since the ABI-defined types are (and need to be) their own main variants. This patch asserts for that instead. 2019-10-31 Richard Sandiford <richard.sandiford@arm.com> gcc/ * config/aarch64/aarch64-sve-builtins.cc (register_builtin_types): Assert that the type we store in abi_vector_types is its own main variant.

2019-10-31[arm] Avoid using negative offsets for 'immediate' addresses when compiling ↵Richard Earnshaw2-7/+15
for Thumb2 Thumb2 code now uses the Arm implementation of legitimize_address. That code has a case to handle addresses that are absolute CONST_INT values, which is a common use case in deeply embedded targets (eg: void *p = (void*)0x12345678). Since thumb has very limited negative offsets from a constant, we want to avoid forming a CSE base that will then be used with a negative value. This was reported upstream originally in https://gcc.gnu.org/ml/gcc-help/2019-10/msg00122.html For example, void test1(void) { volatile uint32_t * const p = (uint32_t *) 0x43fe1800; p[3] = 1; p[4] = 2; p[1] = 3; p[7] = 4; p[0] = 6; } With the new code, instead of ldr r3, .L2 subw r2, r3, #2035 movs r1, #1 str r1, [r2] subw r2, r3, #2031 movs r1, #2 str r1, [r2] subw r2, r3, #2043 movs r1, #3 str r1, [r2] subw r2, r3, #2019 movs r1, #4 subw r3, r3, #2047 str r1, [r2] movs r2, #6 str r2, [r3] bx lr We now get ldr r3, .L2 movs r2, #1 str r2, [r3, #2060] movs r2, #2 str r2, [r3, #2064] movs r2, #3 str r2, [r3, #2052] movs r2, #4 str r2, [r3, #2076] movs r2, #6 str r2, [r3, #2048] bx lr * config/arm/arm.c (arm_legitimize_address): Don't form negative offsets from a CONST_INT address when TARGET_THUMB2.

2019-10-31[arm] Pattern match insns for a + ~b + CarryRichard Earnshaw2-0/+40
On ARM, the SBC instruction is defined as Ra - Rb - ~C where C is the carry flag. But -Rb = ~Rb + 1, so this is equivalent to Ra + ~Rb + 1 - ~C which then simplifies to Ra + ~Rb + C which is essentially an add-with-carry with one operand inverted. We can define RTL patterns to match this. In thumb2 we can only match when the operands are both registers, but in Arm state we can also use RSC to match when Rn is either a constant or a shifted operand. This overall simplifies some cases of 64-bit arithmetic, for example, int64_t f (int64_t a, int64_t b) { return a + ~b; } will now compile to MVN R2, R2 ADDS R0, R0, R2 SBC R1, R1, R3 * config/arm/arm.md (add_not_cin): New insn.

2019-10-30PR c++/84810 - constraints on lambdasJeff Chapman II7-3/+270
Attached is a patch that adds parsing of the optional requires-clause in a lambda-expression and lambda-declarator. Additionally, shorthand constraints from the template-parameter-list are now actually applied and constrain the synthesized operator(). Previously we were not parsing the requires clauses at all and not saving the shorthand constraints in the place expected by grokfndecl. The trailing requires-clause is now also used to suppress synthesis of the conversion to function pointer for non-capturing non-generic lambdas as per expr.prim.lambda.closure/7. This includes a fix to template_class_depth. Previously it was computing the wrong depth for lambdas in the initializer of a static member of a class template, exhibited by the concepts-lambda4 test which currently fails on trunk. The bug was causing grokfndecl to use the constraints from the template class for the lambda. gcc/cp/ 2019-10-30 Jeff Chapman II <jchapman@lock3software.com> PR c++/84810 - constraints on lambdas * lambda.c (maybe_add_lambda_conv_op): Do not synthesize conversion if the call operator does not satisfy its constraints. * parser.c (cp_parser_lambda_declarator_opt): Parse requires-clause on generic lambdas; combine with shorthand constraints.

2019-10-30PR c++/92268 - hard error satisfying return-type-requirementJason Merrill9-13/+43
Previously we would put the template arguments for the concept-check in a TEMPLATE_ID and then also pass them to constraints_satisfied_p, which meant that we would try to normalize the concept-check with the fully instantiated arguments, leading to sadness. Simply not passing the args to constraints_satisfied_p fixes the problem. I also noticed that we weren't detecting substitution failure in the constraints, but were silently treating it as success. * constraint.cc (type_deducible_p): Check for substitution failure. (diagnose_compound_requirement): Adjust diagnostic. * pt.c (do_auto_deduction): Don't pass cargs to constraints_satisfied_p. From-SVN: r277654
