Hard to unit test now when it takes a magic HipeLoaderState
as argument. All hipe testing should be enough exercise for
code:make_stub_module.
|
|
if hipe is disabled.
Makes the code simpler to just ifdef away
a lot of hipe stuff.

Symptom: Got ra==NULL at nsp==nsp_end
when running basic_SUITE:basic_arith on arm
why has this not been detected before?

* Use erts_alloc(ERTS_ALC_T_HIPE_EXEC,_)
* Each module has its own trampolines
|
|
* Use erts_alloc(ERTS_ALC_T_HIPE_EXEC,_)
* Each module has its own trampolines
* Stubs do not use trampolines,
they do their own long jumps.

For non-amd64 it's a "normal" allocator with a
wrapper around mseg_alloc to call mprotect(PROT_EXEC).

from hipe_purge_module.
|

that is only called once.
Basically switch hipe_free_loader_state and hipe_loader_state_dtor.

to not be transformed to local calls.
code_SUITE:uprade still fails if run with compile option
{hipe,to_llvm}

when failing to load native code.

Did not work with purge and made worse by new purge strategy.
Did yield terrible performance when fun thing is created *before*
fun code is loaded. Like when receiving not yet loaded fun
from other node. The cached 'native_address' in ErlFunThing
will not be updated leading to mode switch and error_handler
being called for every call to the fun from native code.

This is part of commit 1bd508921dd93086b05e7d0038b816b36c421d86.
I did not include the fun-checking as we have a new purge strategy
for funs in OTP 20. That remains to be solved some other way for hipe.

Just like the BEAM loader state (as returned by
erlang:prepare_loading/2), the HiPE loader state is contained in a magic
binary.
Eventually, we will separate HiPE loading into a prepare and a finalise
phase, like the BEAM loader, where the prepare phase will be implemented
by hipe_unified_loader and the finalise phase be implemented in C by
hipe_load.c and beam_load.c, making prepare side-effect free and
finalise atomic. The finalise phase will be exposed through the
erlang:finish_loading/1 API, just like the BEAM loader, as this will
allow HiPE and BEAM modules to be mixed in the same atomic "commit".
The usage of a loader state makes it easier to keep track of all
resources allocated during loading, and will not only make it easy to
prevent leaks when hipe_unified_loader crashes, but also paves the way
for proper, leak-free, unloading of HiPE modules.

This commit adds two new structs to be used to represent
erlang code in erts.
ErtsCodeInfo is used to describe the i_func_info header
that is part of all Export entries and the prelude of
each function. This replaces all the BeamInstr * that
were previously used to point to these locations.
After this change the code should never use BeamInstr *
with offsets to figure out different parts of the
func_info header.
ErtsCodeMFA is a struct that is used to descripe a
MFA in code. It is used within ErtsCodeInfo and also
in Process->current.
All function that previously took Eterm * or BeamInstr *
to identify a MFA now use the ErtsCodeMFA or ErtsCodeInfo
where appropriate.
The code has been tested to work when adding a new field to the
ErtsCodeInfo struct, but some updates are needed in ops.tab to
make it work.
