2020-12-31wide-int: Fix wi::to_mpz [PR98474]Jakub Jelinek1-0/+30
The following testcase is miscompiled, because niter analysis miscomputes the number of iterations to 0. The problem is that niter analysis uses mpz_t (wonder why, wouldn't widest_int do the same job?) and when wi::to_mpz is called e.g. on the TYPE_MAX_VALUE of __uint128_t, it initializes the mpz_t result with wrong value. wi::to_mpz has code to handle negative wide_ints in signed types by inverting all bits, importing to mpz and complementing it, which is fine, but doesn't handle correctly the case when the wide_int's len (times HOST_BITS_PER_WIDE_INT) is smaller than precision when wi::neg_p. E.g. the 0xffffffffffffffffffffffffffffffff TYPE_MAX_VALUE is represented in wide_int as 0xffffffffffffffff len 1, and wi::to_mpz would create 0xffffffffffffffff mpz_t value from that. This patch handles it by adding the needed -1 host wide int words (and has also code to deal with precision that aren't multiple of HOST_BITS_PER_WIDE_INT). 2020-12-31 Jakub Jelinek <jakub@redhat.com> PR tree-optimization/98474 * wide-int.cc (wi::to_mpz): If wide_int has MSB set, but type is unsigned and excess negative, append set bits after len until precision. * gcc.c-torture/execute/pr98474.c: New test.
2020-12-31fold-const: Avoid (cast) ((cast2) x p+ y) folding for -fsanitize=alignment ↵Jakub Jelinek1-0/+31
[PR98206] The following testcase is diagnosed by UBSan as invalid, even when it is valid. We have a derived type Base2 at offset 1 with alignment 1 and do: (const Derived &) ((const Base2 *) this + -1) but the folder before ubsan in the FE gets a chance to instrument it optimizes that into: (const Derived &) this + -1 and so we require that this has 8-byte alignment which Derived class needs. Fixed by avoiding such an optimization when -fsanitize=alignment is in effect if it would affect the alignments (and guarded with !in_gimple_form because we don't really care during GIMPLE, though pointer conversions are useless then and so such folding isn't needed very much during GIMPLE). 2020-12-31 Jakub Jelinek <jakub@redhat.com> PR c++/98206 * fold-const.c: Include asan.h.

2020-12-31reassoc: Optimize x > 0x1fff || y > 0x1fff into (x | y) > 0x1fff [PR56719]Jakub Jelinek1-0/+33
The following patch adds an optimization mentioned in PR56719 #c8. We already have the x != 0 && y != 0 && z != 0 into (x | y | z) != 0 and x != -1 && y != -1 && y != -1 into (x & y & z) != -1 optimizations, this patch just extends that to x < C && y < C && z < C for power of two constants C into (x | y | z) < C (for unsigned comparisons). I didn't want to create too many buckets (there can be TYPE_PRECISION such constants), so the patch instead just uses one buckets for all such constants and loops over that bucket up to TYPE_PRECISION times. 2020-12-31 Jakub Jelinek <jakub@redhat.com> PR tree-optimization/56719 * tree-ssa-reassoc.c (optimize_range_tests_cmp_bitwise): Also optimize x < C && y < C && z < C when C is a power of two constant into (x | y | z) < C. * gcc.dg/tree-ssa/pr56719.c: New test.
2020-12-31d: Mangled Symbols now back reference types and identifiersIain Buclaw8-62/+158
Symbols with extern(D) linkage are now mangled using back references to types and identifiers if these occur more than once in the mangled name as emitted before. This reduces symbol length, especially with chained expressions of templated functions with Voldemort return types. For example, the average symbol length of the 127000+ symbols created by a libphobos unittest build is reduced by a factor of about 3, while the longest symbol shrinks from 416133 to 1142 characters.

2020-12-30Make STAT and ERRMSG work on ALLOCATE, move error handling to library.Thomas Koenig4-1/+55
This makes STAT and ERRMSG work on ALLOCATE. It also separates the allocation of coarrays into two functions: One without error checking, which is called by compiler-generated code, and one with error checking for call from user code.

2020-12-23c++: EOF location [PR 96045]Nathan Sidwell47-60/+49
Setting the EOF token location to be the start of a line just after the ending newline is not most helpful. While that location is probably the right place to report preprocessing and lexing issues, when parsing, the location just after the last token is better. That way we get to point at some actual text. Setting the location from the previous token has the advantage over just setting the location to be the end of the final line, in that any ending comments do not get considered, which I think is better.

(gfc_array_allocate): Adjust call to gfc_allocate_shared_coarray. * trans-array.h (gfc_allocate_shared_coarray): Change prototype of cas_coarray_alloc. * trans-decl.c (gfc_build_builtin_function_decls): Adjust cas_coarray_alloc to changed prototypes. (gfc_trans_shared_coarray): Adjust call to gfc_allocate_shared_coarray. * trans-intrinsic.c (gfc_conv_allocated): Set address_only on se. * trans.h: Add flag address_only to gfc_se. libgfortran/ChangeLog: * caf_shared/wrapper.c (cas_coarray_alloc): Add status, error and errmsg arguments and their checking.

2020-12-22c++: Handle array members in build_comparison_op [PR93480]Jakub Jelinek2-0/+73
http://eel.is/c++draft/class.compare.default#6 says for the expanded list of subobjects: "In that list, any subobject of array type is recursively expanded to the sequence of its elements, in the order of increasing subscript." but build_comparison_op just tried to compare the whole arrays, which failed and therefore the defaulted comparison was deleted. The following patch instead compares the array elements, and if info.defining, adds runtime loops around it so that it iterates over increasing subscripts. For flexible array members it punts, we don't know how large those will be, for zero sized arrays it doesn't even try to compare the elements, because if there are no elements, there is nothing to compare, and for [1] arrays it will not emit a loop because it is enough to use [0] array ref to cover everything. 2020-12-21 Jakub Jelinek <jakub@redhat.com> PR c++/93480 * method.c (common_comparison_type): If comps[i] is a TREE_LIST, use its TREE_VALUE instead.

2020-12-22i386: Fix __builtin_floor with FE_DOWNWARD rounding direction [PR96793]Uros Bizjak1-0/+28
x86_expand_floorceil expander uses x86_sse_copysign_to_positive, which is unable to change the sign from - to +. When FE_DOWNWARD rounding direction is in effect, the expanded sequence that involves subtraction can trigger x - x = -0.0 special rule. x86_sse_copysign_to_positive fails to change the sign of the intermediate value, assumed to always be positive, back to positive. The patch adds one extra fabs that strips the sign from the intermediate value when flag_rounding_math is in effect. 2020-12-22 Uroš Bizjak <ubizjak@gmail.com> gcc/ PR target/96793 * config/i386/i386-expand.c (ix86_expand_floorceil): Remove the sign of the intermediate value for flag_rounding_math.

gimplify_init_ctor_eval_range wasn't gimplifying value, so if it wasn't a gimple val, verification at the end of gimplification would ICE (or with release checking some random pass later on would ICE or misbehave). 2020-12-21 Jakub Jelinek <jakub@redhat.com> PR c++/98353 * gimplify.c (gimplify_init_ctor_eval_range): Gimplify value before storing it into cref. * g++.dg/opt/pr98353.C: New test.
2020-12-21fold-const: Fix up a buffer overflow in native_encode_initializer [PR98407]Jakub Jelinek1-0/+10
For flexible array members we need to incrementally clear just from ptr + total_bytes up to new ptr + total_bytes, but memset has been called with the length from ptr, so was missing - total_bytes. Additionally, in this code off is guaranteed to be -1 and thus o 0, so don't bother pretending we could handle anything else, it would be more complicated than that. 2020-12-21 Jakub Jelinek <jakub@redhat.com> PR tree-optimization/98407 * fold-const.c (native_encode_initializer): When handling flexible array members, fix up computation of length for memset. Also remove " - o" as o is always guaranteed to be 0 in this code path. * gcc.c-torture/compile/pr98407.c: New test.
2020-12-21openmp: Fix up handling of addressable temporaries in simd lb, b and incr ↵Jakub Jelinek1-0/+18
expressions [PR98383] For simd, we have code to artificially add locally defined variables into private clauses if they are addressable, so that omplower turns them into "omp simd array" variables. As the testcase shows, this is undesirable if those temporaries only show in the lb, b or incr expressions and nowhere else, if it is just used there, we really want normal scalar temporaries. This patch implements that by making sure we don't set for those GOVD_LOCAL-ish temporaries turned into GOVD_PRIVATE the GOVD_SEEN flag during gimplification of the lb, b and incr expressions, which means that the private clause isn't added for those. 2020-12-21 Jakub Jelinek <jakub@redhat.com> PR c++/98383 * gimplify.c (struct gimplify_omp_ctx): Add in_for_exprs flag. (gimple_add_tmp_var): For addressable temporaries appearing in simd lb, b or incr expressions, don't add a private clause unless it is seen also outside of those expressions in the simd body. (omp_notice_variable): Likewise. (gimplify_omp_for): Set and reset in_for_exprs around gimplification of lb, b or incr expressions. * g++.dg/gomp/pr98383.C: New test.
