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.
2014-04-29erts: Save some space in process struct for hipeSverker Eriksson
by combining hipe.ncallee and hipe.closure in a union as the comment indicate should be possible.
2012-12-20erts,hipe: Make hipe compiler ask running emulator about process struct offsetsSverker Eriksson
Changes in "struct process" has made native code more depenedent on if the executing emulator is smp enabled or not. This commit will make a default built hipe compiler (without -xcomp) to ask the running emulator about process struct offsets. This will make native code work (again) as long as the same emulator is used for compilation as well as execution of the native code.

2012-05-10Remove stale code for hybrid heap and incremental GCBjörn Gustavsson
The hybrid heap emulator was last working in the non-SMP R11B run-time system. When the constant pools were introduced in R12B, the hybrid heap emulator was not updated to handle them. At this point, the harm from reduced readability of the code is greater than any potential usefulness of keeping the code.

2011-11-09erts,hipe: Limited support for hipe cross compilationSverker Eriksson
Normally hipe assumes that generated native code will be executed on the same emulator as the hipe compiler is running on. This commit allows you to build a hipe "cross-compiler" for a different configured emulator (but for same architecture). Example: > cd lib/hipe > make clean > make XCOMP=yes FLAVOR=smp TYPE=debug This hipe compiler will generate code to be executed on the debug compiled smp-emulator at $ERL_TOP.
2011-10-26erts-hipe: Change THE_NON_VALUE for HiPE enabled debug emulatorSverker Eriksson
This is a work-around as there are hipe BIFs that return untagged integers that may be intepreted as THE_NON_VALUE (24). Hipe bifs that return offsets as untagged integers: hipe_bs_put_utf8 hipe_bs_put_utf16be hipe_bs_put_utf16le Hipe bifs that return raw pointers: hipe_find_na_or_make_stub hipe_nonclosure_address

Add hipe_debug_bif_wrapper() as a wrapper for every BIF called by native code.

2010-07-20One off-heap list, to eliminate two words per ETS object.Sverker Eriksson
Merging the three off-heap lists (binaries, funs and externals) into one list. This reduces memory consumption by two words (pointers) per ETS object.
