kandi X-RAY | flags Summary

flags is a Java library typically used in Security, Access Management applications. flags has no bugs, it has no vulnerabilities, it has build file available, it has a Permissive License and it has high support. You can download it from GitHub.

This library is a simple lightweight framework for easily creating and using command line flags. All it takes is a simple annotation with @FlagInfo and an invocation to Flags.parse to create and use a flag! The library uses the Reflections library to scan Flag objects at runtime. This library supports parsing primitive wrapper class types, java.util.Collection types such as List, Set, and Map, and enumerations.

            What is a good technique for compile-time detection of mismatched preprocessor-definitions between library-code and user-code?
            Asked 2022-Apr-04 at 16:07

            Motivating background info: I maintain a C++ library, and I spent way too much time this weekend tracking down a mysterious memory-corruption problem in an application that links to this library. The problem eventually turned out to be caused by the fact that the C++ library was built with a particular -DBLAH_BLAH compiler-flag, while the application's code was being compiled without that -DBLAH_BLAH flag, and that led to the library-code and the application-code interpreting the classes declared in the library's header-files differently in terms of data-layout. That is: sizeof(ThisOneParticularClass) would return a different value when invoked from a .cpp file in the application than it would when invoked from a .cpp file in the library.

            So far, so unfortunate -- I have addressed the immediate problem by making sure that the library and application are both built using the same preprocessor-flags, and I also modified the library so that the presence or absence of the -DBLAH_BLAH flag won't affect the sizeof() its exported classes... but I feel like that wasn't really enough to address the more general problem of a library being compiled with different preprocessor-flags than the application that uses that library. Ideally I'd like to find a mechanism that would catch that sort of problem at compile-time, rather than allowing it to silently invoke undefined behavior at runtime. Is there a good technique for doing that? (All I can think of is to auto-generate a header file with #ifdef/#ifndef tests for the application code to #include, that would deliberately #error out if the necessary #defines aren't set, or perhaps would automatically-set the appropriate #defines right there... but that feels a lot like reinventing automake and similar, which seems like potentially opening a big can of worms)

            One way of implementing such a check is to provide definition/declaration pairs for global variables that change, according to whether or not particular macros/tokens are defined. Doing so will cause a linker error if a declaration in a header, when included by a client source, does not match that used when building the library.

            As a brief illustration, consider the following section, to be added to the "MyLibrary.h" header file (included both when building the library and when using it):

            You can not turn arbitrary classes into hidden classes.

            The documentation of defineHiddenClass contains the sentence

            • On any attempt to resolve the entry in the run-time constant pool indicated by this_class, the symbolic reference is considered to be resolved to C and resolution always succeeds immediately.

            What it doesn’t spell out explicitly is that this is the only place where a type resolution ever ends up at the hidden class.

            But it has been said unambiguously in bug report JDK-8222730:

            For a hidden class, its specified hidden name should only be accessible through the hidden class's 'this_class' constant pool entry.

            The class should not be accessible by specifying its original name in, for example, a method or field signature even within the hidden class.

            Their relationship is like between cargo build and cargo rustc: cargo doc performs all the usual work, for an entire workspace, including dependencies (by default). cargo rustdoc allows you to pass flags directly to rustdoc, and only works for a single crate.

            Here is the execution code for cargo rustdoc. Here is the code for cargo doc. The only differences is that cargo rustdoc always specify to not check dependencies while cargo doc allows you to choose (by default it does, but you can specify the flag --no-deps), and that cargo rustc allows you to pass flags directly to rustdoc with the flags after the --.

            Bubble sort slower with -O3 than -O2 with GCC

            I made a bubble sort implementation in C, and was testing its performance when I noticed that the -O3 flag made it run even slower than no flags at all! Meanwhile -O2 was making it run a lot faster as expected.

            ANSWER

            Answered 2021-Oct-27 at 19:53

            It looks like GCC's naïveté about store-forwarding stalls is hurting its auto-vectorization strategy here. See also Store forwarding by example for some practical benchmarks on Intel with hardware performance counters, and What are the costs of failed store-to-load forwarding on x86? Also Agner Fog's x86 optimization guides.

            (gcc -O3 enables -ftree-vectorize and a few other options not included by -O2, e.g. if-conversion to branchless cmov, which is another way -O3 can hurt with data patterns GCC didn't expect. By comparison, Clang enables auto-vectorization even at -O2, although some of its optimizations are still only on at -O3.)

            It's doing 64-bit loads (and branching to store or not) on pairs of ints. This means, if we swapped the last iteration, this load comes half from that store, half from fresh memory, so we get a store-forwarding stall after every swap. But bubble sort often has long chains of swapping every iteration as an element bubbles far, so this is really bad.

            (Bubble sort is bad in general, especially if implemented naively without keeping the previous iteration's second element around in a register. It can be interesting to analyze the asm details of exactly why it sucks, so it is fair enough for wanting to try.)

            Anyway, this is pretty clearly an anti-optimization you should report on GCC Bugzilla with the "missed-optimization" keyword. Scalar loads are cheap, and store-forwarding stalls are costly. (Can modern x86 implementations store-forward from more than one prior store? no, nor can microarchitectures other than in-order Atom efficiently load when it partially overlaps with one previous store, and partially from data that has to come from the L1d cache.)

            Even better would be to keep buf[x+1] in a register and use it as buf[x] in the next iteration, avoiding a store and load. (Like good hand-written asm bubble sort examples, a few of which exist on Stack Overflow.)

            If it wasn't for the store-forwarding stalls (which AFAIK GCC doesn't know about in its cost model), this strategy might be about break-even. SSE 4.1 for a branchless pmind / pmaxd comparator might be interesting, but that would mean always storing and the C source doesn't do that.

            If this strategy of double-width load had any merit, it would be better implemented with pure integer on a 64-bit machine like x86-64, where you can operate on just the low 32 bits with garbage (or valuable data) in the upper half. E.g.,
