Here, if cp_perform_integral_promotions saw that the TREE_TYPE of a bit-field reference was the same as the type it promotes to, it didn't do anything. But then decay_conversion saw that the bit-field reference was unchanged, and converted it to its declared type. So I needed to add something to make it clear that promotion has been done. But then the 33819 change caused trouble by looking through the NOP_EXPR I just added. This was the wrong fix for that bug; I've now fixed that better by recognizing in cp_perform_integral_promotions that we won't promote a bit-field larger than 32 bits, so we should use the declared type. PR c++/33819 - long bit-field promotion. * typeck.c (cp_perform_integral_promotions): Handle large bit-fields properly. Handle 32-bit non-int bit-fields properly.

In this testcase, !f.b0 was failing to call the overloaded operator because TREE_TYPE is the magic bitfield integer type, and we weren't using unlowered_expr_type the way we do in other places. It would be nice if we could give bit-field COMPONENT_REFs their declared type until genericization time... * call.c (build_new_op_1): Use unlowered_expr_type. From-SVN: r275745
Jason Merrill committed -
While working on C++20 operator<=>, I noticed that build_new_op_1 was doing too much conversion when a built-in candidate was selected; the standard says it should only perform user-defined conversions, and then leave the normal operator semantics to handle any standard conversions. This is important for operator<=> because a comparison of two different unscoped enums is ill-formed; if we promote the enums to int here, cp_build_binary_op never gets to see the original operand types, so we can't give the error. * call.c (build_new_op_1): Don't apply any standard conversions to the operands of a built-in operator. Don't suppress conversions in cp_build_unary_op. * typeck.c (cp_build_unary_op): Do integral promotions for enums. From-SVN: r275744

When we introduced location wrappers, we added fold_for_warn to warnings that are interested in a constant value, or wrapper-stripping to warnings that are interested in literal constants. This particular warning is looking for a literal constant, but was wrongly changed to use fold_for_warn; this patch makes it strip instead. * c-warn.c (warn_logical_operator): Strip location wrappers. Don't fold_for_warn in "|| mask" warning. From-SVN: r275743

For the targets supporting low-overhead loops, IVOPTs has to take care of the loops which will probably be transformed in RTL doloop optimization, to try to make selected IV candidate set optimal. The process of doloop support includes: 1) Analyze the current loop will be transformed to doloop or not, find and mark its compare type IV use as doloop use (iv_group field doloop_p), and set flag doloop_use_p of ivopts_data to notify subsequent processings on doloop. See analyze_and_mark_doloop_use and its callees for the details. The target hook predict_doloop_p can be used for target specific checks. 2) Add one doloop dedicated IV cand {(may_be_zero ? 1 : (niter + 1)), +, -1}, set flag doloop_p of iv_cand, step cost is set as zero and no extra cost like biv. For cost determination between doloop IV cand and IV use, the target hooks doloop_cost_for_generic and doloop_cost_for_address are provided to add on extra costs for generic type and address type IV use. Zero cost is assigned to the pair between doloop IV cand and doloop IV use, and bound zero is set for IV elimination. 3) With the cost setting in step 2), the current cost model based IV selection algorithm will process as usual, pick up doloop dedicated IV if profitable. gcc/ChangeLog 2019-09-14 Kewen Lin <linkw@gcc.gnu.org> PR middle-end/80791 * config/rs6000/rs6000.c (TARGET_HAVE_COUNT_REG_DECR_P): New macro.

According to `gnatmake' documentation: "Any uppercase or multi-character switch that is not a 'gnatmake' switch is passed to 'gcc' (e.g., '-O', '-gnato,' etc.)" however the `--sysroot=' switch is actually rejected: gnatmake: invalid switch: --sysroot=... likely because it is one of the very few GCC driver options that have a leading double dash and therefore we don't have a blanket fall-through for such switches that would satisfy what our documentation claims. The option is actually shared between the compiler and the linker, so pass the switch to both build stages if requested, removing GNAT testsuite issues like: gnatmake: invalid switch: --sysroot=.../sysroot compiler exited with status 1 Executing on host: .../gcc/gnatclean -c -q -n ./abstract_with_anonymous_result (timeout = 300) spawn -ignore SIGHUP .../gcc/gnatclean -c -q -n ./abstract_with_anonymous_result PASS: gnat.dg/abstract_with_anonymous_result.adb (test for excess errors) UNRESOLVED: gnat.dg/abstract_with_anonymous_result.adb compilation failed to produce executable in a test environment where `--with-build-sysroot=.../sysroot' has been used to build a cross-compiler.

Change Named_object::get_backend to ignore aliases when creating type descriptors for types, to be consistent with Type::needs_specific_type_functions and the Specific_type_functions traversal class. For example, when compiling a package that creates an alias to an an externally defined type, e.g. import "foo" type MyFoo = foo.Foo it makes sense to skip the alias (not try to generate type specific functions for it) and let the normal mechanisms take care of the alias target, depending on whether the target is defined locally or defined elsewhere.
