Changelog:
GCC 5.2
This is the [42]list of problem reports (PRs) from GCC's bug tracking
system that are known to be fixed in the 5.2 release. This list might
not be complete (that is, it is possible that some PRs that have been
fixed are not listed here).
Target Specific Changes
IA-32/x86-64
* Support for new AMD instructions monitorx and mwaitx has been
added. This includes new intrinsic and built-in support. It is
enabled through option -mmwaitx. The instructions monitorx and
mwaitx implement the same functionality as the old monitor and
mwait instructions. In addition mwaitx adds a configurable timer.
The timer value is received as third argument and stored in
register %ebx.
For questions related to the use of GCC, please consult these web
pages and the [43]GCC manuals. If that fails, the
[44]gcc-help@gcc.gnu.org mailing list might help. Comments on these
web pages and the development of GCC are welcome on our developer
list at [45]gcc@gcc.gnu.org. All of [46]our lists have public
archives.

and the unversioned one.
As discussed on tech-pkg.

Bug-fix release.
|
|
|
|
- Starting from 18.0 Erlang/OTP is released under the APL 2.0
- erts: The time functionality has been extended. This includes a new API
for time, as well as "time warp" modes which alters the behavior when
system time changes. You are strongly encouraged to use the new API
instead of the old API based on erlang:now/0. erlang:now/0 has been
deprecated since it is a scalability bottleneck.
- erts: Beside the API changes and time warp modes a lot of scalability
and performance improvements regarding time management has been made
- erts: The previously introduced "eager check I/O" feature is now enabled
by default.
- erts/compiler: enhanced support for maps. Big maps new uses a HAMT
(Hash Array Mapped Trie) representation internally which makes them more
efficient. There is now also support for variables as map keys.
- dialyzer: The -dialyzer() attribute can be used for suppressing warnings
in a module by specifying functions or warning options.
- ssl: Remove default support for SSL-3.0 and added padding check
for TLS-1.0 due to the Poodle vulnerability.
- ssl: Remove default support for RC4 cipher suites, as they are consider
too weak.
- stdlib: Allow maps for supervisor flags and child specs
- stdlib: New functions in ets:
- take/2. Works the same as ets:delete/2 but
also returns the deleted object(s).
- ets:update_counter/4 with a default object as
argument

The GNU Compiler Collection (GCC) includes front ends for C, C++, Objective-C,
Fortran, and Go, as well as libraries for these languages (libstdc++,
libgfortran, ...).
This packages provides GCC support libraries in a specific location and allows
packages to depend on just the libraries rather than having to pull in the full
GCC package.

The GNU Compiler Collection (GCC) includes front ends for C, C++, Objective-C,
Fortran, Java, and Go, as well as libraries for these languages (libstdc++,
libgcj,...). This package provides the snapshot release of version 5.
On NetBSD a working cabsl function must be present in libm to build gfortran.
This has been added to -current on 2014/10/10 and to NetBSD7 on 2014/10/13.

2015.07.09, Version 0.12.7 (Stable)
* openssl: upgrade to 1.0.1p
* npm: upgrade to 2.11.3
* V8: cherry-pick JitCodeEvent patch from upstream (Ben Noordhuis)
* win,msi: create npm folder in AppData directory (Steven Rockarts)

changes in sbcl-1.2.13 relative to sbcl-1.2.12:
* incompatible change: on success, TRY-SEMAPHORE and WAIT-ON-SEMAPHORE
return the new count
* enhancement: WAIT-ON-SEMAPHORE accepts a decrement parameter
* enhancement: JOIN-THREAD allows distinguishing timeout vs. abort in all
situations
* enhancement: On Windows DBG_PRINTEXCEPTION_C is handled and its message is
printed. (lp#1437947)
* bug-fix: TRUENAME works properly on broken symlinks presented as
directories. (lp#1458164)
* bug fix: Inlined DPB and DEPOSIT-FIELD don't interfere with left-to-right
order of argument evaluation. (lp#1458190)
* bug fix: (SETF (LDB (BYTE 1 2 JUNK) X) 0) is rightly rejected.
* bug fix: DEFSETF lambda lists should not permit argument destructuring.
* bug fix: calls to (SETF SLOT-VALUE) on a missing slot would in certain
situations incorrectly return the result of a SLOT-MISSING method
instead of always returning the new value. (lp#1460381)
* bug fix: a DEFMACRO occurring not at toplevel and capturing parts of
its lexical environment (thus being a closure) caused expressions
involving the macro name to cause corruption in the pretty-printer
due to faulty introspection of the lambda list of a closure.
* bug fix: out of line MAP/MAP-INTO check that the results produced by the
function are of the matching sequence type. (lp#1459581)
* bug fix: pretty-printing of '(LET `((,X ,Y)) :B) is handled correctly.

include:
- #6583: add a new class of binary operators with the same syntactic
precedence as method calls; these operators start with # followed
by a non-empty sequence of operator symbols (for instance #+, #!?).
It is also possible to use '#' as part of these extra symbols
(for instance ##, or #+#); this is rejected by the type-checker,
but can be used e.g. by ppx rewriters.
* #6016: add a "nonrec" keyword for type declarations
- #6600: make -short-paths faster by building the printing map
incrementally
- #6642: replace $CAMLORIGIN in -ccopt with the path to cma or cmxa
to output an object file with included runtime and autolink libraries
- #6845: -no-check-prims to tell ocamlc not to check primitives in runtime
- G#149: Attach documentation comments to parse tree
- G#159: Better locations for structure/signature items
- #5958: generalized polymorphic #install_printer
- #6237: explicit "infer" tag to control or disable menhir --infer
- #6625: pass -linkpkg to files built with -output-obj.
- #6712: Ignore common VCS directories
- #6720: pass -g to C compilers when tag 'debug' is set
- #6733: add .byte.so and .native.so targets to pass
-output-obj -cclib -shared.
- #6733: "runtime_variant(X)" to pass -runtime-variant X option.
- #6774: new menhir-specific flags "only_tokens" and "external_tokens(Foo)"
- #6285: Add support for nanosecond precision in Unix.stat()
- #6781: Add higher baud rates to Unix termios
- #6834: Add Obj.{first,last}_non_constant_constructor_tag
- #6078: Release the runtime system when calling caml_dlopen
- #6675: GC hooks
- #5418 (comments) : generate dependencies with $(CC) instead of gcc
- #6266: Cross compilation for iOs, Android etc
- Update instructions for x86-64 PIC mode and POWER architecture builds
- #6452, G#140: add internal suport for custom printing formats
- #6641: add -g, -ocamlcflags, -ocamloptflags options to ocamlmklib
- #6693: also build libasmrun_shared.so and lib{asm,caml}run_pic.a

Add a Configure test to verify that including <fenv.h> doesn't produce
a build error, as it will in quite few cases on NetBSD on archs which
are not amd64, i386 or sparc in NetBSD 6.x. If the test build fails,
pretend we don't have fenv.h.
Validated that the result builds on NetBSD/evbarm 6.0 and NetBSD/i386 6.1.5.
Build fix, so no need to bump PKGREVISION.
