Change erts/configure.in to force-disable FP exceptions if
the VM is compiled by clang/llvm. clang/llvm generates FP
code which does not work with FP exceptions (whether unmasked
as used in the Erlang VM, or masked followed by tests of
which are signalled). This is a known long-standing problem.
|
|
The current size is too small for 64-bit machines,
causing messages to be truncated and making debugging
more difficult.

* egil/fix-tmp-alloc-fd-async/OTP-12710:
erts: Use a lockable allocator on 'sys_write_buf'
|
|
* joudinet/fix-ac-egrep-cpp-usage:
erts: Fix incorrect use of AC_EGREP_CPP
OTP-12706
|
|
sys_write_buf allocator type is used from async-threads and needs
to be lockable. In the SMP case the temporary allocator is lockable but
not in the Non-SMP case.
To remedy this the binary-allocator is used for the Non-SMP case,
which is lockable.

Using 'AC_EGREP_CPP(yes' without restraining the pattern always return
true if it runs from a path containing the string 'yes'.

OTP-12685

Seen on SSL application where substraction with x registers were prevalent:
* i_minus specialization on x registers
* i_plus specialization on x registers
|
|
Common pattern seen in SSL:
move y x | move r x -> move2
move r x | move y x -> move2
Common pattern seen in SSL and Compiler:
move x r | move x x -> move2

May lessen load/store latency.
|
|
A type error caused the optimization to never kick in.
|
|
Move an entire region of x registers to the stack.
This reduces the dispatch pressure of move instructions.
Also introduce a move2 specialization for some common move patterns:
move r y | move x y -> move2 : As above, moving regions to the stack
move x r | move x y -> move2 : A seemingly common pattern
|
|
|
|
* i_is_lt for r, x registers and constants
* i_is_ge for x registers and constants
* i_is_exact_eq for r and x registers

This fixes arity 4 BIF support in HiPE, following its introduction
on master (OTP 18) via the nox/ets-update_counter-4 merge.
- define standard_bif_interface_4, nbif_4_gc_after_bif, and
nbif_4_simple_exception on ARM: unbreaks the build on ARM
- remove bogus stack re-alignment from standard_bif_interface_4
on AMD64: for 4-arg BIFs the stack is already aligned, and the
code would misalign the C stack which violates the ABI and may
cause alignment faults in vectorized code
- the nbif_4_simple_exception OPD name on PPC64 was incorrectly
using the nbif_3_simple_exception OPD name: this would have
caused a multiple definition error in the assembler or linker
In addition there are a few cleanups:
- fix standard_bif_interface_N comment on x86
- fix standard_bif_interface_4 comment on SPARC
- separate nbif_N_simple_exception blocks by empty lines on PPC,
like on ARM, to clearly show which things belong together
- fix standard_bif_interface_N comment on ARM
- fix standard_bif_interface_4 on AMD64 to match the indentation
and spacing conventions of the rest of that file
