The C++11 requirement that an explicit exception-specification on a defaulted function match the implicit one was found to be problematic for std::atomic.

When using lto-dump -callgraph with two or more .o files containing distinct functions with the same name, dump_graphviz incorrectly merged those functions into a single node. This patch fixes this issue by calling `dump_name` instead of `name`, therefore concat'ing the function name with the node's id. To understeand what was the issue, let's say you have two files: a.c: static void foo (void) { do_something (); } b.c: static void foo (void) { do_something_else (); } These are distinct functions and should be represented as distinct nodes in the callgraph dump. 2019-10-22 Giuliano Belinassi <giuliano.belinassi@usp.br> * cgraph.c (dump_graphviz): Change name to dump_name From-SVN: r277299

2019-10-22[arm] Match subtraction from carry_operationRichard Earnshaw3-0/+26
On Arm we have both carry and borrow operations, but borrow is essentially '~carry'. Of course, with boolean logic ~carry is also 1-carry. GCC transforms (1 - X - LTU (cc, 0)) into (GEU (cc, 0) - X) Now the former matches a real insn in Arm state, using the RSC instruction with #1 as the immediate, but we currently do not recognize the canonicalized form. Nevertheless, given the above logic, this turns out to be quite straight forward as the original expression matches arm_borrow_operation and the revised form can be used with arm_carry_operation. Since we match this new pattern we also update rtx_costs to handle it. * config/arm/arm.md (rsbsi_carryin_reg): New pattern. * config/arm/arm.c (arm_rtx_costs_internal, case MINUS): Handle subtraction from a carry operation.

2019-10-22Fix use after free in vector_size changeRichard Sandiford3-9/+18
r277235 was a bit too mechanical and ended up introducing use after free bugs in both loop and SLP vectorisation. 2019-10-22 Richard Sandiford <richard.sandiford@arm.com> gcc/ * tree-vect-slp.c (vect_slp_bb_region): Check whether autodetected_vector_size rather than vector_size is zero. * tree-vect-loop.c (vect_analyze_loop): Likewise. Set autodetected_vector_size immediately after calling vect_analyze_loop_2. Check for a fatal error before advancing next_size. From-SVN: r277282
2019-10-22[C++] Avoid exposing internal details in aka typesRichard Sandiford9-38/+372
This patch extends r276951 to work for C++ too. 2019-10-22 Richard Sandiford <richard.sandiford@arm.com> gcc/cp/ * cp-tree.h (STF_USER_VISIBLE): New constant. (strip_typedefs, strip_typedefs_expr): Take a flags argument. * tree.c (strip_typedefs, strip_typedefs_expr): Likewise, updating mutual calls accordingly. When STF_USER_VISIBLE is true, only look through typedefs if user_facing_original_type_p. * error.c (dump_template_bindings, type_to_string): Pass STF_USER_VISIBLE to strip_typedefs. (dump_type): Likewise, unless pp_c_flag_gnu_v3 is set. gcc/testsuite/ * g++.dg/diagnostic/aka5.h: New test. * g++.dg/diagnostic/aka5a.C: Likewise. * g++.dg/diagnostic/aka5b.C: Likewise. * g++.target/aarch64/diag_aka_1.C: Likewise.

2019-10-22[testsuite] Make the Wnonnull independent of system headers.Iain Sandoe2-11/+10
To avoid the result of this test depending on the implementation of the system 'string.h', provide prototypes for the two functions used in the test. gcc/testsuite/ChangeLog: 2019-10-22 Iain Sandoe <iain@sandoe.co.uk> * gcc.dg/Wnonnull.c: Provide prototypes for strlen and memcpy. Use __SIZE_TYPE__ instead of size_t. From-SVN: r277280
