* weisslj/fix-gcc40-arm-compile-error/OTP-11214:
Fix compile error on ARM and GCC < 4.1.0

Smoke tests are meant to verify that a build of erlang has been successfull.

Bug reported by Jose Valim on the erlang-bugs mailing list:
erlang:halt(0,[]) does not flush as advertised in the documentation.
Should be the same as erlang:halt(0,[{flush,true}]), but is in fact
the same as erlang:halt(0,[{flush,false}]).

* weisslj/run-erl-redirect-dev-null/OTP-11215:
run_erl: Redirect standard streams to /dev/null
|
|
Some basic tests are already done in configure. This makes sure we
cover all cases by bailing out when compiling as well.

* sze/to_erl/OTP-11206:
Fix changing terminal parameters in to_erl
|
|
One of our devices does not like 'to_erl' to be run over a serial port.
When to_erl is started, we see "Attaching to /tm<0xFF>" being printed
and the device then refuses to accept any input. Occasionally, we have
seen a linux kernel error message "serial8250: too much work for irq16"
simultaneously. After some debugging we found out that cause is a call
to tcsetattr() by to_erl, immediately preceeded by some printf().
The UART in our device doesn't like hardware parameters to be changed
while output is concurrently active. In fact, the GNU libc manual also
mentions that it might be dangerous to change UART hardware parameters
when a transmission is ongoing.
The patch attached to this e-mail changes the behaviour of to_erl to use
TCSADRAIN instead of TCSANOW when changing terminal parameters. This
makes the serial driver wait for the output queues to be empty before
applying the terminal parameter change.

Since b29ecbd (OTP-10418, R15B03) Erlang does not compile anymore with
old versions of GCC that do not have atomic ops builtins on platforms
where there is no native ethread implementation (e.g. ARM):
In file included from ../include/internal/gcc/ethread.h:29,
from ../include/internal/ethread.h:354,
from beam/erl_threads.h:264,
from beam/erl_smp.h:27,
from beam/sys.h:413,
from hipe/hipe_mkliterals.c:29:
../include/internal/gcc/ethr_membar.h:49:4: error: #error "No __sync_val_compare_and_swap"
This patch adds a header guard in "gcc/ethread.h", as is present in
"libatomic_ops/ethread.h".

Build with fallback can be enabled by passing the `configure` command
line argument `--disable-smp-require-native-atomics`

Like in epmd and erlexec. Otherwise "run_erl" fails on some platforms
when called with the "-daemon" option, printing this error:
"Cannot dup"

with better performance than aoffcaobf as we don't have to rearrange
the search tree when there are blocks of equal size.

This complements 933e701 (OTP-10209). Without this patch the test cases
"in_guard/1" and "coerce_to_float/1" in bs_construct_SUITE fail.
The added lines in bs_construct_SUITE cover all branches that were not
covered before (small and big numbers if BIT_OFFSET(erts_bin_offset) != 0).

This complements 933e701 (OTP-10209). Without this patch the test case
"bs_match_misc_SUITE:t_float/1" fails.
Simple error example:
1> <<_,_,_,_,_,_,_,_>> = <<1.25/float>>.
<<63,244,0,0,0,0,0,0>>
2> <<1.25/float>> = <<63,244,0,0,0,0,0,0>>.
** exception error: no match of right hand side value <<63,244,0,0,0,0,0,0>>
The additional test case is added because in a former version of this
patch the ERTS_FP_ERROR_THOROUGH check for NaN/infinity was mistakenly
applied on the still word-switched double.

This complements 933e701 (OTP-10209). Without this patch the test case
"hash_SUITE:test_phash2/1" fails.
Simple error example:
1> 77147068 = erlang:phash2(1.0).
** exception error: no match of right hand side value 50524433
