2017-02-03dialyzer: Do not keep the code server's type info on the heapHans Bolinder
The table used during translation of forms to types used to be a dictionary of the type info (-type(), -opaque(), and -record()) for all modules. Now it is reduced to the modules that are needed to handle references to types in other modules. The PLT:s type info is still kept on the heap.

2017-01-10dialyzer: Fix check of parameterized opaque typesHans Bolinder
Two parameters used to be "compatible" if one is a specialization of the other, in the way that the input type of t_limit() is a specialization of the output type. This check is now relaxed: any() in any of the two parameters is compatible with any type of the other parameter. The change is due to bugus warnings. A clause for maps has been added.
2016-12-21stdlib: Allow characters in types and constant patternsHans Bolinder
Characters ($char) can be used in constant pattern expressions. They can also be used in types and contracts.

2016-11-19hipe_icode_call_elim: Fix cf elimination crashMagnus Lång
hipe_icode_call_elim could in some cases replace an #icode_call{} with control flow with a move instruction. This would break the control flow graph invariants and cause a crash.
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).
2016-11-16hipe_x86: Fix encoding of test instr w/ neg immMagnus Lång
Also, use byte form for immediates up to 255, since there's no sign extension in byte form. HiPE seems to never generate negative test immediates currently, but we should at least not output incorrect encodings.
2016-11-16hipe_tagscheme: Simplify test_two_fixnums with immMagnus Lång
test_two_fixnums would previously only check its right-hand argument for immediates, but not it's left. Now, test_two_fixnums reduces to test_fixnum if either argument is an immediate.
2016-11-16hipe_icode: Always const-propagate if&call argsMagnus Lång
2016-11-16hipe_tagscheme: x86 lea+test for mask_and_compareMagnus Lång
By changing mask_and_compare from and,sub to sub,and, x86 can use a 3-address LEA immediate add, saving a mov. The RISC backends should see no change in sequence length. We make test_(heap_|sub)binary use mask_and_compare so they will benefit too.
2016-11-16hipe_tagscheme: Improve fixnum_addsub with immMagnus Lång
The addsub sequence was suboptimal when one of the arguments was immediate, because it became an immediate alu followed by an immediate alub, and the optimisers would not combine them due to the risk of altering the branch. However, in this case we know that such a rewrite is safe, and do it directly in hipe_tagscheme:fixnum_addsub/5 instead.
2016-11-16hipe: Make realloc_binary fast case true branchMagnus Lång
This makes the fast case a fallthrough and the slow case a branch, hopefully improving cache locality.
2016-11-16hipe_x86_postpass: Negate conditions in goto elimMagnus Lång
2016-11-16hipe_tagscheme: Improve fixnum add on x86Magnus Lång
With the introduction of immediate adds encoded as 'LEA' on x86, it is now possible to do a fixnum add in two instructions and one branch by commuting the addition and reusing the result register as a temporary, which makes the 'alub' a 2-address add, saving a move instruction.
2016-11-15hipe_rtl_to_x86: Use LEA only for immediate addsMagnus Lång
It seems that most 3-address adds of temps can be move coalesced. Therefore, we limit the behaviour added by 1567585dda8 to only affect immediate adds. Also, add conversion of immediate mov+sub to lea.
2016-11-15hipe_x86: LeaToAdd peephole ruleMagnus Lång
Although LEA is useful for three-address form adds, sometimes it is used where a normal add would have sufficed (due to the addition being the last use of one of the operands; but RTL lowering does not know that as it does not have liveness information). As a workaround, we convert LEA back to ADD when the destination is the same as one of the operands.

2016-11-15hipe_rtl: drop alub dest when unusedMagnus Lång
2016-11-15hipe_rtl: unify branch and alubMagnus Lång
branch and alub overlap in their use cases, but the backends rely on knowing that the result is unused in their lowering of branch. By extending alub so that the destination is optional, it can fully replace branch. This simplifies rtl by reducing code duplication and the number of instructions. Also, in the x86 and arm backends, we can now use 'test' and {'tst','mvn','teq'} to lower some alubs without destinations. This is particularly good for x86, as sequences such as 'is_boxed' type tests now get shorter (both from not needing a mov to copy the variable, but also from the fact that 'testb' encodes shorter than 'andq').

2016-11-08hipe_rtl_to_llvm: Constants for bits per byte/wordMagnus Lång
The constant ?WORD_WIDTH is renamed ?BITS_IN_WORD, and a new constant ?BITS_IN_BYTE is introduced. Additionally, a bug in a currently unused case clause of llvm_type_from_size/1 is fixed (the size of a word was hardcoded to 64 bits).
