v3_kernel may produce unwanted and confusing warnings for code that
has been inlined with the new inliner (cerl_inline). Consider this
code:
-compile(inline).
compute1(X) ->
add(X, 0).
compute2(X, Y) ->
add(X, Y).
add(1, 0) ->
1;
add(1, Y) -> %% "this clause cannot match..."
1 + Y;
add(X, Y) ->
X + Y.
v3_kernel warns because add/2 has been inlined into compute1/1 and only
the first clause in add/2 will match. But the other clauses are needed
when add/2 is inlined into compute2/2, so the user cannot do anything
to eliminate the warning (short of manually inlining add/2, defeating the
purpose of the 'inline' option).
The warning would be reasonable if compute2/2 didn't exist, but it would
be too complicated for the compiler to figure whether a warning make
sense or not.
Therefore, suppress all warnings generated by v3_kernel if cerl_inline
has been run.

* ingela/odbc/mac:
odbc: Remove support for old MACs
|
|
Change configure to skip odbc for old MACs, the change in
PR-1227 is not backwards compatible with old MACs, and we do not
see a need to continue support for such old versions. However
it is still possible to make it work on such machines using
the --with-odbc configure option.

ECC certs should preferably use SHA2, this is what we want to be
testing. Also assembling of all available test suites must consider TLS version.

Update to look for -lodbc as well as default to /usr/local as you will need to brew install libiodbc.

The constant ?WORD_WIDTH is renamed ?BITS_IN_WORD, and a new constant
?BITS_IN_BYTE is introduced.
Additionally, a bug in a currently unused case clause of

bits).

As of LLVM 3.9, the x86-call-frame-opt pass in LLVM's X86 backend causes
the stack descriptors to contain incorrect (or even negative) frame
sizes or root slot offsets.
This might cause LLVM-compiled modules to be rejected during loading
with a badarg exception in hipe_bifs:enter_sdecs/1 (which additionally
prints a "hipe_bifs_enter_sdesc_1: bad sdesc!" message to stderr), or it
might cause corruption or segmentation faults when walking stacks (f.ex.
during GC) containing frames compiled with ErLLVM.
As a workaround, we pass the -no-x86-call-frame-opt flag to llc when
the version is at least 3.9

ErLLVM was declaring atoms in the following manner:
@atom_ok = external constant i64
; Used inside a function like this
%var = ptrtoint i64* @atom_ok to i64
However, doing so makes LLVM think the `atom_ok` is 8-byte aligned,
since it refers to a i64 value. This resulted in LLVM occasionally
incorrectly optimising away type tests on atoms, causing incorrect
behaviour or even segfaults. One such case is in
bs_match_compiler:coverage_apply/2, in which an is_boxed test on a
literal atom was optimised away, causing the code to try and load the
"header" of an atom. This problem reproduces with LLVM versions 3.7
through 3.9.
By declaring atoms as i8 (byte) constants instead, LLVM no longer makes
these alignment assumptions, and the bug is fixed.

This fixes a HiPE bug reported on erlang-questions on 2/11/2016.
The BEAM to ICode tranaslation of the bs_match_string instruction,
written long ago for binaries (i.e., with byte-sized strings), tried
to do a `clever' translation of even bit-sized strings using a HiPE
primop that took a `Size' argument expressed in *bytes*.
ICode is not really the place to do such a thing, and moreover there
is really no reason for the HiPE primop not to take a Size argument
expressed in *bits* instead. This commit changes the `Size' argument
to be in bits, postpones the translation of the bs_match_string primop
Fixed in a pair-programming/debugging session with @margnus1.
until RTL and does a proper translation using bit-sized quantities there.

As per RFC 4492 Sec 5.1, the preferred order of selection of named
curves is based on client preferences.
Currently, the SSL application only picks entries according to the
absolute order of entries as tracked in a hardcoded list in code.
This patch changes things so that the client-specified order is
preferred. It also allows a mode where the server can be configured to
override the client's preferred order with its own, although the chosen
ECC must still be within both lists.
The configuration is done through the following options:
- `eccs`, shared by clients and servers alike, allows the specification
of the supported named curves, in their preferred order, and may
eventually support more values for explicit primes and so on.
- `honor_ecc_order`, a server-only option, is similar to
`honor_cipher_order` and will, by default let the server pick the
client-preferred ECC, and otherwise pick the server-preferred one.
The default value for `eccs` is the same as before, although the
server-chosen ECC now defaults to the client rather than previous
choice.
A function `ssl:eccs()` has been added that returns the highest
supported ECCs for the library.
