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

* rickard/make-fixes-21/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.

2018-12-07Mark free blocks in pooled carriers as unused (MADV_FREE)John Högberg
This lets the OS reclaim the physical memory associated with these blocks which reduces the impact of long-lived awkward allocations. A small allocated block will still keep a huge carrier alive, but the unused part of the carrier will now be available to the OS. Co-authored-by: Dmytro Lytovchenko <[email protected]>

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.
