* Revert "Rename _closure to _static_closure, apply naming consistently."Edward Z. Yang2014-10-201-36/+36

* Rename _closure to _static_closure, apply naming consistently.Edward Z. Yang2014-10-011-36/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: In preparation for indirecting all references to closures, we rename _closure to _static_closure to ensure any old code will get an undefined symbol error. In order to reference a closure foobar_closure (which is now undefined), you should instead use STATIC_CLOSURE(foobar). For convenience, a number of these old identifiers are macro'd. Across C-- and C (Windows and otherwise), there were differing conventions on whether or not foobar_closure or &foobar_closure was the address of the closure. Now, all foobar_closure references are addresses, and no & is necessary. CHARLIKE/INTLIKE were not changed, simply alpha-renamed.

* Package keys (for linking/type equality) separated from package IDs.Edward Z. Yang2014-08-051-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch set makes us no longer assume that a package key is a human readable string, leaving Cabal free to "do whatever it wants" to allocate keys; we'll look up the PackageId in the database to display to the user. This also means we have a new level of qualifier decisions to make at the package level, and rewriting some Safe Haskell error reporting code to DTRT. Additionally, we adjust the build system to use a new ghc-cabal output Make variable PACKAGE_KEY to determine library names and other things, rather than concatenating PACKAGE/VERSION as before. Adds a new `-this-package-key` flag to subsume the old, erroneously named `-package-name` flag, and `-package-key` to select packages by package key. RFC: The md5 hashes are pretty tough on the eye, as far as the file system is concerned :( ToDo: safePkg01 test had its output updated, but the fix is not really right: the rest of the dependencies are truncated due to the fact the we're only grepping a single line, but ghc-pkg is wrapping its output. ToDo: In a later commit, update all submodules to stop using -package-name and use -this-package-key. For now, we don't do it to avoid submodule explosion. Signed-off-by: Edward Z.

* Raise exceptions when blocked in bad FDs (fixes Trac #4934)Sergei Trofimovich2014-06-081-0/+2
| | | | | | | | | | | | | | | Before the patch any call to 'select()' with 'bad_fd' led to: - unblocking of all threads - hiding exception for 'threadWaitRead bad_fd' The patch fixes both cases in this way: after 'select()' failure we iterate over each blocked descriptor and poll individually to see it's actual status, which is: - READY (move to run queue) - BLOCKED (leave in blocked queue) - INVALID (send an IOErrror exception) Signed-off-by: Sergei Trofimovich <slyfox@gentoo.org>

* Per-thread allocation counters and limitsSimon Marlow2014-05-021-0/+2
| | | | | | | | | | | | | | | | | | | | | | | This tracks the amount of memory allocation by each thread in a counter stored in the TSO. Optionally, when the counter drops below zero (it counts down), the thread can be sent an asynchronous exception: AllocationLimitExceeded. When this happens, given a small additional limit so that it can handle the exception. See documentation in GHC.Conc for more details. Allocation limits are similar to timeouts, but - timeouts use real time, not CPU time. Allocation limits do not count anything while the thread is blocked or in foreign code. - timeouts don't re-trigger if the thread catches the exception, allocation limits do. - timeouts can catch non-allocating loops, if you use -fno-omit-yields. This doesn't work for allocation limits. I couldn't measure any impact on benchmarks with these changes, even for nofib/smp.

* Change how we handle libffiIan Lynagh2013-03-231-1/+1
| | | | | | | | | | | I think overall the new approach is simpler. Rather than unpacking the libffi.a and putting the .o files into our libHSrts.a, we just use the libffi.a. This change also means that when compiling programs for the dyn way, they get explicitly linked against libffi.so (rather than relying on librts.so being linked against it). This might fix a problem on FreeBSD, where programs cannot find libffi.so.

* Build the dynamic way by default on Linux/amd64Ian Lynagh2012-10-031-1/+1
| | | | | | | | | | | | | This required various build system changes to get the build to go through. In the inplace shell wrappers, we set LD_LIBRARY_PATH to allow programs to find their libraries. In the future, we might change the inplace tree to be the same shape as an installed tree instead. However, this would mean changing the way we do installation, as currently we use cabal's installation methods to install the libraries, but that only works if the libraries are under libraries/foo/dist-install/build/..., rather than in inplace/lib/...

| | | | | | * Pass -Irts/dist/build to the C preprocessor to expose libffi headers (ffi.h and ffitarget.h) to foreign import wrappers during the building process of GHC itself. * Install libffi headers into $(ghcheaderdir) just like any other C headers. Otherwise an installed GHC can't find them when it wants to compile foreign import wrappers. * Include libffi headers in the bindist for the same reason.
* Move includes/DerivedConstants.h and includes/GHCConstants.h into dist dirsIan Lynagh2011-12-021-1/+1
| | | | | | | | | | When they existed, they were getting included in the includes_H_FILES variable (as it uses wildcard to find all header files). But the .depends files for the programs that generate the headers depend on $(includes_H_FILES), so the .depends files looked out-of-date once the headers had been created. This caused unnecessary make reinvocations. So now we put them in dist* directories, where they ought to be anyway.

* Simplify the libffi buildIan Lynagh2011-10-141-1/+0
| | | | | | | We now put the libffi objects into the RTS library, rather than trying to mangle libffi into being a ghc package itself. It would be nicer to make it a separate library (but not a ghc package), but for now hopefully this will get the build going through on Windows again.
