* bg/compiler-inliner:
pmod_SUITE: Again test inlining parameterized modules
compiler tests: Cope with missing args in function_clause for native code
compiler tests: Compile a few more modules with 'inline'
Consistently rewrite an inlined function_clause exception to case_clause
compiler tests: Test the 'inline' option better
compiler: Suppress bs_context_to_binary/1 for a literal operand
compiler: Fix binary matching bug in the inliner
sys_core_inline: Don't generated multiple compiler_generated annos
OTP-8552 bg/compiler-inliner
Several problems in the inliner have been fixed.
|
|
The runtime system crashed if fewer logical processors were found than
reported by sysconf( SC_NPROCESSORS_CONF).
|
|
The use of mmap() was unnecessarily disabled when cross compiling.
The configure arguments --with-ssl, and --with-odbc refused to accept
libraries outside of $erl_xcomp_sysroot when cross compiling for no good
reason.
The configure argument --with-odbc didn't handle the value yes correct.
The configure arguments --with-odbc, and --without-odbc have also been
added to the configure help.
(Thanks to Steve Vinoski for reporting these issues)

Unfortunately, commit 1e2ecf8c492b6d499880b8676e3c1fe0c5793103
removed all cond support except for two lines.

* mh/doc-inet-getopts:
Doc fix: inet:getopts/2 returns {ok, OptionValues}, not just OptionValues
|
|
* mh/doc-loose-lose:
Fix spelling: "loose" is not a verb
|
|
* se/decode_packet:
Fix erlang:decode_packet(httph_bin,..) to not return faulty header strings
OTP-8548 se/decode_packet
erlang:decode_packet(httph_bin,..) could return corrupt header strings or
even crash the VM. This has been fixed. It only happened on 32-bit VM if
the header name was unknown and between 16 and 20 characters long. Sockets
with simular packet option did not suffer from this bug.
|
|
* bd/mnesia-activity-subscription:
Add mnesia activity subscription message
|
|
A process that calls mnesia:subscribe(activity) will receive the message:
{mnesia_activity_event, ActivityID, complete}
when any activity that caused a change to a database has finished
committing its changes. This allows a subscriber to collect messages
already available through the mnesia:subscribe({table, ...}) system
to group them as completed transactions.

Commit of the generated code with previous commit.
Fixed code generation from newer doxygen versions.

Commit 91de9d0670c6fe1cff08cefa6e1c396effba47b8 stopped testing
inlining of parameterized modules, because of a bug in the inliner.
|
|
Unrecognized Http header names was sometimes returned as corrupt
sub-binaries pointing to a stack allocated buffer. This only happened
on 32-bit VM if the header name was between 16 and 20 characters
long. It could in some cases lead to segmentation fault.
The solution was to avoid creating sub-binary if the returned string
was not part of the original binary.

"Lose" means not "not win", but "loose" means "not tight".
Change "loose" to "lose" where appropriate.
|
|
Native-compiled code generates a different stack trace for
function_clause exceptions - instead of the arguments for the
function, only the arity is reported. Accept missing arguments
if the test suite is native-compiled.
|
|
Since a function_clause exception in an inlined function will
be changed to a case_clause exception, we must test for both.
|
|
A function_clause exception is generated by jumping to a func_info/3
instruction at the beginning of the function. The x registers are
assumed to contain the arguments for the function. That means
that a func_info/3 instruction copied from another function
(or even from the same function if not at the top level) will
not work, so it must be replaced with an instruction that
generates a case_clause exception.
In Core Erlang, a func_info/3 instruction is represented as
a the primop match_fail({function_clause,Arg1,...ArgN}).
The current mechanism that is supposed to replace the
primop match_fail(function_clause) with match_fail(case_clause)
will fail to do that in the following circumstances:
1. If the inliner has inlined a function into itself.
Fix that by having the inliner clear the function_name annotations
on all match_fail primops in functions that are inlined. (To simplify
doing that, the annotation is now on the primop node itself and not on
the 'function_clause' atom inside it.)
2. If the inliner has rewritten the tuple node in the primop node
to a literal (when inlining a function call with literal arguments),
v3_kernel would not recognize the match_fail(function_clause) primop
and would not rewrite it. Fix it by making v3_kernel smarter.
Also simplify the "old" inliner (sys_core_inline) to only clear
the function_name annotations instead of rewriting function_clause
execptions to case_clause execptions itself.
|
|
Clone some test suites and compile them with the 'inline' option
to test inlining more thorughly.
|
|
The inliner can cause illegal uses of the bs_context_to_binary/1
instruction, such as:
bs_context_to_binary {literal,"string"}
or
bs_context_to_binary {integer,1}
Remove the bs_context_to_binary/1 instruction if the operand
is not a register (it is clearly not needed).
|
|
The inliner incorrectly assumes that a literal cannot
match a binary in code such as:
t() ->
bc(<<"string">>).
bc(<<A:1,T/bits>>) -> [A|bc(T)];
bc(<<>>) -> [].
The bug was introduced when binary literals were introduced.
|
|
Multiple compiler_generated annotations are harmless, but makes
listing files harder to read during debugging.

* bg/compiler-remove-r11-support:
compiler: Don't support the no_binaries option

compiler: Don't support the no_constant_pool option
compiler: Don't support the r11 option
test_server: Don't support communication with R11 nodes

erts: Test compatibility of funs with R12 instead of R11

New ssl now properly handles ssl renegotiation, and initiates a
renegotiation if ssl/ltls-sequence numbers comes close to the max value.
|
|
|
|
|
|
The no_binaries option terminates the compiler with an error
if any bit syntax is used in the module being compiled.
(It used to be implied by the removed r11 option.)
|
|
Since R14 does not need to load code that can also be loaded
in an R11 run-time system, support for the put_string/3
instruction can be removed.
|
|
The no_constant_pool option was implied by the r11 option. It turns
off the usage of the constant (literal) pool, so that BEAM
instructions that use constants can be loaded in an R11 system.
Since the r11 option has been removed, there is no need to
retain the no_constant_pool option.
|
|
The r11 option was used to generate BEAM modules that could
loaded both on both R11 and R12/R13 to facilitate testing
that R11 and R13 nodes could communicate with each other.
Since R14 is only required to be compatible with R12 and
R13 nodes, the r11 option is no longer needed.
|
|
Since R14 does not need to be compatible with any older Erlang
systems than R12, we no longer need to use the r11 compiler
option when compiling the test_server_node module.

Since "otp_build update_primary" copies files that may contain
trailing spaces, the commit may fail if the repository has a
pre-commit hook that refuses to commit files with whitespace
problems. Avoid the problem by not running any hooks.

Erlang/OTP R11B.
