2018-01-29erts: Refactor hipe x86_64 trampolinesSverker Eriksson
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.

2016-10-14erts: Remove dead alloc stats in hipe_amd64.cSverker Eriksson
erlang:system_info({allocator, exec_alloc}) have stats if we need it.
2016-10-14erts: Use hipe_free_moduleSverker Eriksson
2016-10-10erts: Improve hipe load/upgrade/purge machinerySverker Eriksson
A step toward better integration of hipe load and purge Highlights: * code_server no longer needs to call hipe_unified_loader:post_beam_load/1 Instead new internal function hipe_redirect_to_module() is called by loading BIFs to patch native call sites if needed. * hipe_purge_module() is called by erts_internal:purge_module/2 to purge any native code. * struct hipe_mfa_info redesigned and only used for exported functions that are called from or implemented by native code. A list of native call sites (struct hipe_ref) are kept for each hipe_mfa_info. * struct hipe_sdesc used by hipe_find_mfa_from_ra() to build native stack traces.

2016-04-15erts: Add 'exec_alloc' for hipe codeSverker Eriksson
that uses its own super carrier (erts_exec_mmapper) to guarantee low addressed and executable memory (PROT_EXEC). Currently only used on x86_64 that needs low memory for HiPE/AMD64's small code model. By initializing erts_exec_mapper early we secure its low memory area before erts_literal_mmapper might steal it.

2015-01-26hipe: improve error handling at code allocation failureMikael Pettersson
2015-01-26hipe: remove two obsolete BIFsMikael Pettersson
The hipe_bifs:make_native_stub/2 and hipe_bifs:get_emu_address/1 BIFs were originally used by hipe_unified_loader.erl, but the code been obsolete and disabled for ages. Remove the BIFs and all references to them. In hipe_unified_loader.erl, remove the no-op emu_make_stubs/1 function.
2014-04-29erts: Fix global tracing of beam function when called from hipe codeSverker Eriksson
Make hipe to beam calls use export entry. Makes it a lot easier to handle global tracing correctly (breakpoints in export entry). A beam function should now be traced correctly regardless how it is called. This will also fix a SEGV crash when a hipe stub is made pointing into a traced export entry and tracing is then stopped which clears the export entry causing the hipe stub to execute beam instruction NULL. This commit assumes that hipe code never calls local beam functions, which should be the case nowadays as we only hipe compile entire modules.
