-====== Installing Valgrind ======
+===== Valgrind =====
-===== Installing from ports =====
+The recommended installation method is %%FreeBSD%% Ports & Packages.
-//pkg install valgrind// will install Valgrind 3.18.1.
+===== Installation =====
-//pkg install valgrind-devel// will install a version of Valgrind that is tracking the upstream git repository, 3.18.0.GIT.
+Note: There may be some differences or delays between binary package versions and port versions, depending on whether you use [[QuarterlyBranch|Quarterly]] or Latest package branch.
-**There may be some delay between package builds and the above versions, particularly if you use the quarterly packages**'
+==== Stable Version ====
-===== Prerequisites =====
+The ''%%devel/valgrind%%'' port follows the official Valgrind release cycle, which is roughly aligned with the %%RedHat%% Fedora release cycle, with bi-annual releases targeted for April and October.
-Building valgrind requires the following ports to be installed:
-  * gmake
-  * autoconf
-  * automake
-===== Obtaining the Valgrind source =====
+Install using either:
-Starting with Valgrind 3.18.1 %%FreeBSD%% support has been integrated into the main Valgrind codebase.
+  * Ports: ''%%cd /usr/ports/devel/valgrind && make install%%'' OR
+  * Packages: ''%%pkg install valgrind%%''
-[[https://valgrind.org/|TheValgrindHomePage]]
+==== Development Version ====
-[[https://valgrind.org/downloads/current.html|GettingTheLatestValgrindSource]]
+The ''%%devel/valgrind-devel%%'' port will install a version of Valgrind that is tracking the upstream git repository, and is updated if/when there are sufficient fixes between official Valgrind releases.
-Prior to 3.18.1 (though still maintained) the source was hosted on on github.

 ===== TODO =====
-  - Signal delivery issue, particularly on i386 [fixed in the sourceware repo, not yet in ports]
+  - Implement a %%FreeBSD%% fair scheduler. Linux has a futex based scheduler. It uses come GCC ''%%__sync%%'' builtins (also available with clang). And a couple of syscalls for futex. Shouldn't be too hard to port to use _umtx_op.
-  - Differences between lld and ld-bfd concerning ELF sections.
-  - A proper implementation of vgdb-invoker.
-  - Add freeres support to libc [[https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=259294|FreeresBugzillaItem]]
-  - Much needs to be done for clang OMP.
-  - Fix support for %%FreeBSD%% TLS TLS does affect Helgrind and possibly DRD.
-    * http://people.freebsd.org/~marcel/tls.html %%FreeBSD%% TLS notes
-    * http://lwn.net/Articles/5851/ Linux TLS notes
   - Implement rfork.
+    * See https://github.com/paulfloyd/freebsd_valgrind/issues/197
+  - Improve vgdb-invoker.
+  - Implement some form of lldb-server.
+  - Improve core dumps. Currently they are just Linux style core dumps with a %%FreeBSD%% tag.
+  - Add freeres support to libc [[https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=259294|FreeBSD Bugzilla Issue #259294]]
+  - Much needs to be done for Clang OMP.
+  - Fix handling of thread TLS allocation for Helgrind.
