2016-11-19hipe: Improve error message on internal crashesMagnus Lång
Print the MFA/module being compiled, and pretty-print the backtrace with lib:format_stacktrace/4. Additionally, make the error_msg/2 macro in hipe.hrl respect the HIPE_LOGGING define, since messages produced by this macro just before runtime shutdown were sometimes lost (since code_server:error_msg/2 is asynchronous).

2016-09-05hipe: Add ra_partitioned to o1 and upMagnus Lång
ra_partitioned significantly speeds up register allocation of larger functions without affecting allocation quality negatively. This is the final change needed to make o1 suitable for compiling really large functions without choking.
2016-09-02hipe_ppc: Add code rewrite RA callbacksMagnus Lång
These will not only be useful for hipe_regalloc_prepass, but also, after the introduction of a mk_move/2 (or similar) callback, for the purpose of range splitting. Since the substitution needed to case over all the instructions, a new module, hipe_ppc_subst, was introduced to the ppc backend.
2016-09-02hipe_sparc: Add code rewrite RA callbacksMagnus Lång
These will not only be useful for hipe_regalloc_prepass, but also, after the introduction of a mk_move/2 (or similar) callback, for the purpose of range splitting. Since the substitution needed to case over all the instructions, a new module, hipe_sparc_subst, was introduced to the sparc backend.
2016-09-02hipe_arm: Add code rewrite RA callbacksMagnus Lång
These will not only be useful for hipe_regalloc_prepass, but also, after the introduction of a mk_move/2 (or similar) callback, for the purpose of range splitting. Since the substitution needed to case over all the instructions, a new module, hipe_arm_subst, was introduced to the arm backend.
2016-09-02hipe_x86: Add code rewrite RA callbacksMagnus Lång
These will not only be useful for hipe_regalloc_prepass, but also, after the introduction of a mk_move/2 (or similar) callback, for the purpose of range splitting. Since the substitution needed to case over all the instructions, a new module, hipe_x86_subst, was introduced to the x86 backend. Due to differences in the 'jtab' field of a #jmp_switch{} between x86 and amd64, it regrettably needed to be duplicated to hipe_amd64_subst.
2016-09-02hipe: Add IG partitioning to hipe_regalloc_prepassMagnus Lång
2016-09-02hipe: Add hipe_regalloc_prepassMagnus Lång
hipe_regalloc_prepass speeds up register allocation by spilling any temp that is live over a call (which clobbers all register). In order to detect these, a new function was added to the target interface; defines_all_alloc/1, that takes an instruction and returns a boolean.
2016-08-30hipe: Fix o0 and o1Magnus Lång
These options would not do anything, because they would not supress the 'o2' in ?COMPILE_DEFAULTS. Such behaviour is added to expand_options/2.
2016-08-30hipe: Add o0 and o1 to testsMagnus Lång
Now that x86 is no longer broken with these optimisation levels, we add them to the test suite to ensure they do not break again. Bump timeout to 6min since tests are run twice as many times. The option set of o1 was changed to all optimisations that run fast on both big and small programs, incurring only a slight compile time increase compared to the old set, but with a, presumably, significant improvement to speed of compiled code. Change o0 register allocator to linear_scan.
2016-08-30hipe_x86: LSRA for SSE2Magnus Lång
There is little point offering LSRA for x86 if we're still going to call hipe_graph_coloring_regalloc for the floats. In particular, all allocators except LSRA allocates an N^2 interference matrix, making them unusable for really large functions.

2016-07-11hipe_sdi: Use segment trees to represent PARENTSMagnus Lång
This speeds up parentsOfChild/2 from O(n) to O(lg n + k). A new module misc/hipe_segment_trees.erl is introduced.

2016-05-23Added elimination of maps:is_key/2 calls to HiPEMagnus Lång
* Implemented removal of maps:is_key/2 calls of which the result is known in a new pass during the typed phase, called hipe_icode_call_elim. * Added the option icode_call_elim that enables the hipe_icode_call_elim pass, and made it default for o2.
2016-05-11hipe_llvm: Disable floats for x86Magnus Lång
A bug in LLVM miscompiles x86 functions that have floats are spilled to stack. We work around it by disabling (inlined) floats when using llvm on x86. Once a LLVM version in which the bug is fixed is released, we can make the workaround conditional depending on the version.

2015-10-09Update and cleanup HiPE recordsKostis Sagonas
The bulk of the changes concerns cleanups and code refactorings concerning record constructions that assigned 'undefined' to record fields whose type did not contain this value. See commit 8ce35b2. While at it, some new type definitions were introduced and type names were used instead of record type notation. Minor code cleaups were also done.
2015-08-31erts,hipe,dialyzer: Fix hipe checkum of target runtime systemSverker Eriksson
Main problem: A faulty HIPE_LITERAL_CRC was not detected by the loader. Strangeness #1: Dialyzer should ask the hipe compiler about the target checksum, not an internal bif. Strangeness #2: The HIPE_SYSTEM_CRC checksum was based on the HIPE_LITERALS_CRC checksum. Solution: New HIPE_ERTS_CHECKSUM which is an bxor of the two (now independent) HIPE_LITERALS_CRC and HIPE_SYSTEM_CRC. HIPE_LITERALS_CRC represents values that are assumed to stay constant for different VM configurations of the same arch, and are therefor hard coded into the hipe compiler. HIPE_SYSTEM_CRC represents values that may differ between VM variants. By default the hipe compiler asks the running VM for this checksum, in order to create beam files for the same running VM. The hipe compiler can be configured (with "make XCOMP=yes ...") to create beam files for another VM variant, in which case HIPE_SYSTEM_CRC is also hard coded. ToDo: Treat all erts properties the same. Either ask the running VM or hard coded into hipe (if XCOMP=yes). This will simplify and reduce the risk of dangerous mismatches. One concern might be the added overhead from more frequent calls to hipe_bifs:get_rts_param.
2015-08-24erts: Change THE_NON_VALUE to not be hard coded in hipe compilerSverker Eriksson
Instead ask running VM for the value of THE_NON_VALUE, which is different between opt and debug VM. Same hipe compiler can now compile for both opt and debug VM.

2015-06-13Simplify handling of o2 and o3 option expansionKostis Sagonas
A recent rewrite of some code in this file (commit 355f4b5) exposed some dialyzer warnings of some code which is unreachable. Indeed, checking whether one executes on an unsupported architecture when expanding the 'o2' and 'o3' hipe compiler options is unnecessary because that check is performed in the expansion of the 'o1' option anyway. While at it, simplified the code a bit not to have a very long case clause.

2015-05-25Update runtime_dependencies in application resource filesHans Bolinder
Applications that use the new erl_anno module are depending on STDLIB 2.5. Note that CosNotification, Megaco, SNMP, Xmerl, and Parsetools use the erl_anno module via the Yecc parsers only (the header file in lib/parsetools/include/yeccpre.hrl calls the erl_anno module). HiPE does not call the erl_anno module, but uses an exported type. We have chosen to make HiPE dependent on the erl_anno module.

2014-03-20Introduce runtime_dependencies in .app filesRickard Green
Most dependencies introduced are exactly the dependencies to other applications found by xref. That is, there might be real dependencies missing. There might also be pure debug dependencies listed that probably should be removed. Each application has to be manually inspected in order to ensure that all real dependencies are listed. All dependencies introduced are to application versions used in OTP 17.0. This since the previously used version scheme wasn't designed for this, and in order to minimize the work of introducing the dependencies.
2014-03-07Support the LLVM backend in HiPEYiannis Tsiouris
Add flags to enable and use the LLVM backend: * to_llvm: use the LLVM pipeline for compilation (default optimization level is O3), * llvm_save_temps: save the intermediate files in current directory in order to be able to debug or optimize the LLVM assembly, * {to_llvm, O}: set the optimization level of LLVM opt and llc tools. Add some debug support to the loader; no semantic change intented.
2014-02-24Make hipe non-upgradable by setting appup file emptyTobias Schlager
The reason for this is that if you are running a system with native compiled code, then you will have major problems with soft upgrade and the only reasonable way to go is to restart your emulator. Currently there is no instruction that will force ONLY a restart of the emulator, so the solution would be to hand write a relup with only a restart_emulator instruction. By letting hipe.appup be empty, systools will complain and not generate a relup - which should indicate that you might have to write your relup by hand.
2014-02-24Fix missing module on hipe app file templateTobias Schlager
2014-02-18Fix library application appup filesTobias Schlager
As discussed in issue #240 *all* OTP library applications use the '.*' wildcard as up and down version. This makes library applications always up- and downgradeable. Using the wildcard version obsoletes all maintenance tasks regarding library applications' appup files. Additionally, it prevents upgrade problems caused by automatically included application dependencies when using reltool to create releases. Missing copyright headers are now consistently present.
2013-03-12Loosen the assumptions of code that handles escaping functionsKostis Sagonas
The HiPE compiler implicitly relied on the assumption that a function will never appear as both exported and also used as function closure. This was true because the BEAM compiler prior to R16B created module local anonymous functions for each closure. A proposed change to the BEAM compiler invalidates this invariant, so in order to accommodate for this change there needs to be a change of how the set of possibly escaping functions is computed. While doing this, the code was simplified by taking out a boolean() tag that indicated whether a function is a closure or exported and also slightly cleaned up the affected modules.

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.
