2018-01-29make HiPE work on x86_64 when PIE is enabledbhuztez
Currently HiPE amd64 assumes the runtime system code is loaded into the low 2G of the address space. However, this is not the case when PIE is enabled, it is loaded into a random location. So trampolines are required to call BIFs, and also we have first to load the address of sse2_fnegate_mask to a regisiter before xorpd in fchs.

2017-10-05Use 32-bits pointers to C codeBjörn Gustavsson
On a 64-bit machine, we only need 32 bits to store a pointer to the C code that implements a BEAM instruction. Refactor the code to only use the lower 32 bits of each instruction word, and take care to preserve the high 32 bits.

2017-07-04macOS: Fix problems loading cryptoBjörn Gustavsson
On macOS, it was not possible to start crypto after running observer. (ERL_251) On the beta of macOS 10.13 (High Sierra), crypto does not work at all. (ERL-439) The problem is that the use of the -flat_namespace option when linking dynamic drivers such as the one for crypto. With that option, all function names must be unique among all linked libraries and frameworks, or the wrong function could be called. Resolve the problem by using the two-level namespace as recommended by Apple. We need to use the -bundle_loader option to point out beam.smp when building all drivers and NIF libraries. https://bugs.erlang.org/browse/ERL-251 https://bugs.erlang.org/browse/ERL-439

2017-05-16Let --enable-lock-counter build an additional emulatorBjörn Gustavsson
"./configure --enable-lock-counter" would modify the behavior of the default emulator (usually SMP). To make lock counting more accessible, change --enable-lock-counter to build an additional emulator in the same way as: (cd erts/emulator && make lcnt) (The next commit will make it easier to start the built lock-counter emulator.)

2017-03-30Don't imply --disable-hipe in --enable-m32-buildMagnus Lång
HiPE compiles and runs perfectly well with --enable-m32-build on linux. If there are some darwin-specific issues with --enable-m32-build and --enable-hipe, a more specific test for these conditions should be added.

2017-03-29Partially revert commit 37d63e9b8a0a96125ada858205286a58a5bed1aeKostis Sagonas
The above commit erroneously declared 'ppc64le' as a 'ppc64' for HiPE enabling. These two architectures are different and one can NOT expect that native code generated for one architecture runs on the other one. Rather than reverting this commit, make sure that the architecture is declared correctly instead of pretending it's a PPC64.

Some linkers, for example on Gentoo Hardened, do not accept the -no-pie flag but require the -fno-PIE flag instead.
2017-02-06Implement magic referencesRickard Green
Magic references are *intentionally* indistinguishable from ordinary references for the Erlang software. Magic references do not change the language, and are intended as a pure runtime internal optimization. An ordinary reference is typically used as a key in some table. A magic reference has a direct pointer to a reference counted magic binary. This makes it possible to implement various things without having to do lookups in a table, but instead access the data directly. Besides very fast lookups this can also improve scalability by removing a potentially contended table. A couple of examples of planned future usage of magic references are ETS table identifiers, and BIF timer identifiers. Besides future optimizations using magic references it should also be possible to replace the exposed magic binary cludge with magic references. That is, magic binaries that are exposed as empty binaries to the Erlang software.

2016-12-02configure.in: Fix configure test for usable OpenSSLBjörn Gustavsson
In OpenSSL 1.1.0, HMAC_CTX no longer has a complete definition, and can no longer be allocated as a stack variable. Therefore, the code in the configure test for usable OpenSSL library will not compile. Call the HMAC() function instead since it exists in all versions of of OpenSSL that we support. Note that the code will only be compiled and linked, not run, so the argument values don't matter as long as they have the correct type.
2016-12-02configure.in: Fix test for SSL with KerberosBjörn Gustavsson

2016-10-13Revert "Check libsctp for sctp funcs in configure.in"Raimo Niskanen
This reverts commit 52fae83743a6e84d719f4f82fe45e6e0efdbd6f0: Check libsctp for sctp funcs in configure.in Call AC_CHECK_LIB before calling AC_CHECK_FUNCS to check for functions in libsctp. Otherwise AC_CHECK_FUNCS will not link with libsctp to see if function exists. Reverting to the old behaviour of not checking for libsctp before checking for sctp functions. Then it works on Linux by loading libsctp and looking up the symbols i runtime, and it works on FreeBSD since there is no separate libsctp to link against - the functions are part of the default system libraries.
