Instead rely on gnu make's pre-defined RM variable which should equal 'rm -f'

* rickard/make-fixes-20/OTP-15551: Fix install phase in build system - Install of (mainly) documentation caused rebuild and modification of the source tree even when the source previously had been built. Also otp_patch_apply modified the source tree when updating documentation. This messed up the installation if installation was performed by another user than the user that originally built the system which not is an uncommon scenario. - Some documentation was installed by copying files instead of installing the files which caused faulty access rights on files. - The documentation was not properly updated when applying a patch using otp_patch_apply.

Note that the ERTS_NO_RETPOLINE macro introduced by this commit is completely inert unless spectre-mitigation is set to 'incomplete.' This includes when mitigation has been manually enabled through CFLAGS, so it should be impossible for it to unintentionally disable mitigation.

2018-05-09Disable the use of floating point exceptionsBjörn Gustavsson
Floating point exceptions has been disabled since 2011 on macOS (fa0f8d2c29b) and on Linux since 2014 (c7ddafbe6dbc) because there were unresolved stability issues. Floating point exceptions are not disabled by default on FreeBSD, and if OTP is compiled with gcc (as opposed to clang) floating point exceptions will be used. 81a6adab693a introduced a bug in erts/emulator/Makefile.in which would cause the building of OTP to fail if floating point exceptions were enabled. The bug was not noticed because it turns out that none of our daily build machines has floating point exceptions enabled. Since floating point exceptions is not tested, we should not expect them to work reliably on any platform. Therefore, turn off floating point exceptions unconditionally in erts/configure.in. For the moment we will keep the code in the runtime system that handles floating point exceptions. (This commit also fixes the bug in erts/emulator/Makefile.in, in case floating point exceptions ever become reliable and enabled.) https://bugs.erlang.org/browse/ERL-620

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.

* maint: macOS: Fix problems loading crypto
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.)
