* Rename _closure to _static_closure, apply naming consistently.Edward Z. Yang2014-10-0115-122/+126
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* BC-breaking changes to C-- CLOSURE syntax.Edward Z. Yang2014-10-011-10/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Previously, there were two variants of CLOSURE in C--: - Top-level CLOSURE(foo_closure, foo, lits...), which defines a new static closure and gives it a name, and - Array CLOSURE(foo, lits...), which was used for the static char and integer arrays. They used the same name, were confusing, and didn't even generate the correct internal label representation! So now, we have two new forms: - Top-level CLOSURE(foo, lits...) which automatically generates foo_closure (along with foo_info, which we were doing already) - Array ANONYMOUS_CLOSURE(foo, lits...) which doesn't generate a foo_closure identifier.

* Implement `decodeDouble_Int64#` primopHerbert Valerio Riedel2014-09-174-0/+37
| | | | | | | | | | | | | | | The existing `decodeDouble_2Int#` primop is rather inconvenient to use (and in fact is not even used by `integer-gmp`) as the mantissa is split into 3 components which would actually fit in an `Int64#` value. However, `decodeDouble_Int64#` is to be used by the new `integer-gmp2` re-implementation (see #9281). Moreover, `decodeDouble_2Int#` performs direct bit-wise operations on the IEEE representation which can be replaced by a combination of the portable standard C99 `scalbn(3)` and `frexp(3)` functions.

* Revert "Revert "rts/base: Fix #9423"" and resolve issue that caused the revert.Andreas Voellmy2014-09-164-30/+74
| | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This reverts commit 4748f5936fe72d96edfa17b153dbfd84f2c4c053. The fix for #9423 was reverted because this commit introduced a C function setIOManagerControlFd() (defined in Schedule.c) defined for all OS types, while the prototype (in includes/rts/IOManager.h) was only included when mingw32_HOST_OS is not defined. This broke Windows builds. This commit reverts the original commit and resolves the problem by only defining setIOManagerControlFd() when mingw32_HOST_OS is defined. Hence the missing prototype error should not occur on Windows. In addition, since the io_manager_control_wr_fd field of the Capability struct is only usd by the setIOManagerControlFd, this commit includes the io_manager_control_wr_fd field in the Capability struct only when mingw32_HOST_OS is not defined. Test Plan: Try to compile successfully on all platforms. Reviewers: austin Reviewed By: austin Subscribers: simonmar, ezyang, carter Differential Revision: https://phabricator.haskell.org/D174
* Fix cppcheck warningsBoris Egorov2014-09-161-3/+6

This commit fixes them. Cppcheck 1.54 founds three possible null pointer dereferences of ioMan pointer. It is dereferenced and checked for NULL after that. testheapalloced.c contains typo in printf statement, which should print percent sign but treated as parameter placement by compiler. To properly print percent sign one need to use "%%" string. FYI: Cppcheck 1.66 cannot find possible null pointer dereferences in mentioned places, mistakenly thinking that some memory leaking instead. I probably fill a regression bug to Cppcheck. Test Plan: Build project, run 'make fulltest'. It finished with 28 unexpected failures. I don't know if they are related to my fix.
