2016-09-05hipe: Refactor ra callbacks to accept context argMagnus Lång
This allows us to pass around the context data that hipe_regalloc_prepass needs cleanly, without using process dictionary or parameterised modules (like it was previous to this change).
2016-09-05hipe: Reuse liveness between regalloc iterationsMagnus Lång
This is sound because the liveness data structure only stores liveness info at basic block boundaries, and the rewrites that happen in TargetSpecific:check_and_rewrite/2 preserves all existing definitions and uses, and all new liveness intervals, belonging to newly introduced temporaries, are always local to a basic block, and thus do not show up in the liveout or livein sets for the basic block.
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: 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_ppc: Minimise CFG<->linear conversionsMagnus Lång
Now, there will only ever be a single Linear->CFG conversion, just after lowering from RTL, and only ever a single CFG->Linear conversion, just before the finalise pass. Both of these now happen in hipe_ppc_main.
2016-08-30hipe_ppc: Be resilient to crappy RTLMagnus Lång
The PowerPC backend crashes if certain RTL optimisations were omitted, preventing it from being usable at lower optimisation levels.
2016-08-30hipe: Reuse liveness info for spillminMagnus Lång
For x86, additionally reuse liveness from float LSRA for the GP LSRA.

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.

2015-01-11hipe: backends: correct #fconv{} translationMikael Pettersson
RTL can produce an #fconv{} instruction with an immediate operand, but the backends unconditionally access the operand as a temporary. This results in broken representation in the backends and eventually they crash.
2014-03-07Move some common code in hipe_pack_constantsYiannis Tsiouris
All backends (e.g. arm, ppc, sparc, x86) share the same code for the following functions: * find_const/2, * mk_data_relocs/2, and * slim_sorted_exportmap/3 This commit moves those definitions (along with some helper functions) in misc/hipe_pack_constants.erl and adds the appropriate specs. This is a structural change; no change in semantics intented.

2010-01-26OTP-8343 The documentation is now possible to build in an open sourceLars G Thorsen
environment after a number of bugs are fixed and some features are added in the documentation build process. - The arity calculation is updated. - The module prefix used in the function names for bif's are removed in the generated links so the links will look like http://www.erlang.org/doc/man/erlang.html#append_element-2 instead of http://www.erlang.org/doc/man/erlang.html#erlang:append_element-2 - Enhanced the menu positioning in the html documentation when a new page is loaded. - A number of corrections in the generation of man pages (thanks to Sergei Golovan) - Moved some man pages to more apropriate sections, pages in section 4 moved to 5 and pages in 6 moved to 7. - The legal notice is taken from the xml book file so OTP's build process can be used for non OTP applications.
