Valgrind For Mac
2021年6月18日Download here: http://gg.gg/v1sz1
Welcome to my blog, where I’ll be discussing some of the work I’m doing for Mozilla.
This is the homepage of the profiling tool Callgrind and the profile data visualization KCachegrind.Both are licensed under GPL V2. Callgrind uses runtime instrumentation via the Valgrind framework for its cache simulation and call-graph generation. This way, even shared libraries and dynamically opened plugins can be profiled. Valgrind is only compatible with x86 binaries on Mac OS, so if you have x8664 you’ll need to ensure that x86 binaries are being built. To do this, right click on the project and select Properties. Within the Properties window, select C/C Build then add ’-m32’ to the Command field for the MacOS X C Linker, GCC C Compiler and GCC C Compiler.
Valgrind 3.16.0 for MacOS Mojave 10.14.6 8th April 2020 8th April 2020 / By Roland Ihasz / C, Software Development, Static Code Analyzers / mac, OSX, Qt, Valgrind After many unstable versions and unsuccessful tries found a working but still experimental solution for. Valgrind - a suite of tools for debugging and profiling programs SYNOPSIS top valgrind valgrind-options your-program your-program-options DESCRIPTION top Valgrind is a flexible program for debugging and profiling Linux executables. It consists of a core, which provides a synthetic CPU in software, and a series of debugging and profiling.A little about me
I’m Australian. I live in Melbourne. I’ve also lived in Cambridge, England and Austin, Texas, and so I am fluent in at least three dialects of English. I like spending time with my wife Phoebe and baby daughter Keira, eating food, riding my bike, and following US presidential elections obsessively. Two weeks ago I left the academic/research world and started working for Mozilla.Valgrind
My first big task for Mozilla is to improve support for Mac OS X in Valgrind. I’ve been involved with Valgrind since before the 1.0 release in 2002, and have done lots of work on it, including writing two tools that are in the Valgrind distribution: Cachegrind, a cache profiler, and Massif, a memory profiler. I even wrote a PhD dissertation about it.
And it seems that lots of Mozilla people find Valgrind useful, which is nice. However, it currently only runs on Linux. (Well, it also runs on AIX, but not many people care about that.)Valgrind on Mac OS X
More than four years ago, on December 16, 2004, an Apple employee named Greg Parker wrote to the Valgrind developers mailing list to tell us that he was working on a port of Valgrind for Mac OS X. He’s been working on it ever since then. (This must be why Mac OS 10.5 shipped late.)
After such a long time, I’m happy to report that there is now a branch holding Greg’s port in the Valgrind SVN repository. If you want to check it out, do this:
and then build it according to the instructions in the README file. The branch is called DARWIN because Darwin is the name of the Mac OS “core”, which consists of a Mach-based microkernel and a few other bits and pieces.
However, please note that the port currently is, in Greg’s words: “UNSUPPORTED and INCOMPLETE and BUGGY… It may not find bugs in your program, or run your program correctly, or run your program at all.” What Greg has done is very impressive, and goes an awfully long way towards having a complete port of Valgrind on Mac OS X. But it’s not the cleanest patch ever. To give you an idea…Valgrind For Mac Osx
*The patch I imported was 31,144 lines, just over 1MB of text.
*The patch initially didn’t work on 32-bit Macs.
*The patch broke Valgrind on Linux. This took me a couple of days to fix, mostly involving the addition of appropriate #if statements.
*The patch broke the regression test system; they wouldn’t even build, let alone run. After fixing them to run again, more than half of the tests failed on Linux, and almost three-quarters failed on Mac.
*There are lots of compiler warnings. (The Valgrind trunk has none).
*Much of the code in the patch has 4 space indenting; the rest of Valgrind code has 3 space indenting.Valgrind For Mac
So there’s plenty of work to be done to get the branch into a state where it will be suitable for merging with the trunk. It’s hard to estimate how long this will take, it will just be a matter of fixing things one piece at a time. My guess is that three months might suffice, but it’s really just a guess. But here are some metrics I can use to judge progress, and their values just after I got the the system and regression tests building and running again on Mac and Linux:
*The number of regression test failures on Linux: 477 tests, 220 stderr failures, 53 stdout failures, 25 post failures. (“stderr” failures generally indicate that Valgrind’s output had a problem, “stdout” failures generally indicate that the test program’s output had a problem, and “post” failures indicate that the output of a Valgrind post-processing step had a problem.) These numbers roughly indicate how much existing functionality has been broken on Linux by the Darwin changes, and should be fairly easy to get down.
*The number of regression test failures on Mac: 419 tests, 293 stderr failures, 58 stdout failures, 29 post failures. These numbers are the most important, as they roughly indicate how complete the Mac functionality is, and will be much more work to get down.
*The number of compiler warnings: 186. This number should be easy to reduce. (Update, Jan 20: That’s on Linux. On Darwin it was 461.)
*The size of the diff between the branch and the trunk: 55,852 lines, 1.9MB. This is larger than the original patch because some files have been moved on the branch but not yet moved on the trunk, including some tests that are large and have large expected outputs. This number will go down in fits and starts; it will never get to zero, as the final merge will happen when there are many differences between the branch and trunk.
I’ll occasionally post updates to these numbers so people can track progress.Valorant Mac
If Valgrind-on-Mac is of interest to you, please try out the new branch and let me know how it goes. Note that I’m working on an old MacBook Pro which is only 32-bit, so it’s possible that I’ve broken the 64-bit Mac support, but have no way to determine this.

Below are a few of the important events in the history of Valgrind:
*
14 August 2017: Valgrind source code repository migrated from Subversion to git SCM at sourceware.org.
*
4 Februrary 2017: Third Valgrind devroom at FOSDEM 2017, Brussels, Belgium.
*
31 January 2015: Second Valgrind devroom at FOSDEM 2015, Brussels, Belgium.
*
2 February 2014: First Valgrind devroom at FOSDEM 2014, Brussels, Belgium.
*
21 October 2010: Valkyrie-2.0.0, a Qt4-based GUI for the Memcheck and Helgrind tools in Valgrind-3.6.0, is now available.
*
July 1 2010: Initial support for Mac OS X 10.6 (Snow Leopard) has been folded into the trunk and is usable. Support for 64-bit executables on 10.5 and 10.6 has also been improved. Note that to build a 64-bit capable Valgrind, which is probably what you need on 10.6, you must use the configure-time flag ’--build=amd64-darwin’. For more details see the repository page.
*
July 1 2010: Initial support for the SSE4.1/4.2 instruction set has been folded into the trunk, for 64-bit processes only at present. The implementation is incomplete but is believed to cover all instructions generated by gcc-4.4/4.5 ’-O3 -msse4.2’. Work on further coverage is ongoing. For more details see the repository page.
*
May 6 2010: Initial support for ARM/Linux has been folded into the SVN trunk, and is usable on Ubuntu 9.04 and 9.10 for ARM. Further development to support more recent Ubuntus and the full ARMv7 instruction set is in progress. For more details see the repository page.
*
May 5 2010: Valgrind t-shirts are available for purchase at FreeWear.org. For each t-shirt sold, 3 &euro will be donated to the Valgrind project.
*
August 19 2009: valgrind-3.5.0, for X86/Linux, AMD64/Linux, PPC32/Linux, PPC64/Linux and X86/Darwin (Mac OS X) is available. (release notes).

This release runs on {x86,amd64,ppc32}-linux. 3.1.0 brings much improved support for AMD64, improved memory management on all platforms, and support for 32-bit PowerPC/Linux. Also at this time we are releasing matching versions of the Callgrind profiling tool and Valkyrie GUI.
*
November 21 2005: The results of the September survey have been put on the surveys page.
*
October 8 2005: Our survey is over. Thanks to all those who participated. An analysis will be posted soon.
*
