2019-01-29ssl: Improve openssl interop testsPéter Dimitrov
openssl 1.1.x changed the default ECC curves that made testcases fail in the ECC suite. openssl s_server and s_client sent 'Illegal Parameter' alert when the CertificateVerify (client) or ServerKeyExchange (server) message was signed with a curve that was not present in openssl's default ECC curve list (x25519, secp256r1, secp521r1, secp384r1, brainpoolP256r1, brainpoolP384r1, brainpool512r1). This commit changes the default curve of make_ec_cert_chains to 'secp256r1' and explicitly configures the default curve in those testcases where the default curve of the ssl application is expected.

2019-01-28beam_validator: Add explicit assertions for fragile termsJohn Högberg
We haven't seen any related bugs so far, but all instructions that place a term in another ought to reject fragile inputs. It can't hurt to check.
2019-01-28beam_validator: Refactor type managementJohn Högberg
Our current type management (based on set_type_reg etc) is rather error-prone, often requiring special cases on a per-instruction basis. This commit replaces nearly all ad-hoc mechanisms with more general abstractions: * assign - Moves a term. * create_term - Creates a new term. * extract_term - Extracts a term from another, maintaining fragility as required. * update_type - Adds more type information about a register. * type_test - Helper function for type tests that subtracts on failure and meets on success.
2019-01-28beam_except: Eliminate unsafe function_clause translationBjörn Gustavsson
The translation from `error(function_clause, Args)` to a jump to the `func_info` label is not safe if there is a stack frame.
2019-01-28Speed up beam_ssa_deadBjörn Gustavsson
Compilation of code similar the following would be very slow: uts46_map(CP) when 0 =< CP, CP =< 44 -> '3'; uts46_map(CP) when 45 =< CP, CP =< 46 -> 'V'; uts46_map(CP) when 48 =< CP, CP =< 57 -> 'V'; %% More than 2500 similar lines follows. . . . The code is from from: https://github.com/benoitc/erlang-idna/blob/3eb54ccbfa6fb917c0f4ca9197da337ad888ffe0/src/idna_mapping.erl#L6780 By using information about skippable blocks, the beam_ssa_dead pass can be sped up to compile idna_mapping.erl about 10 times faster.
2019-01-28Speed up ssa_opt_merge_blocksBjörn Gustavsson
It is never possible to merge a block ending in a switch with the next block, so it is not necessary to call `beam_ssa:successors/1` in that case. Avoiding the call slightly improves compilation speeds for switches with many branches.
2019-01-28Fix crash in beam_ssa_typeBjörn Gustavsson
To improve compilation times, beam_ssa_type keeps track of variables that are only used once and don't keep types for those variables. As currently implemented, it turns to be unsafe. Change it to only keep track of variables that are only used in the terminator of the block they are defined in. https://bugs.erlang.org/browse/ERL-840
2019-01-28beam_ssa_opt: Make phase/4 tail-recursiveBjörn Gustavsson
If compilation failed, the name of the current function *and* all previously compiled functions would be printed because phase/4 was not tail-recursive. https://bugs.erlang.org/browse/ERL-840

2019-01-24Make the beam_validator smarter again, againJohn Högberg
The fix in f9ea85611faca82c7494449ddb8bcb1ef1d194cb didn't consider that the tested register could be aliased.
2019-01-24beam_trim: Ignore type annotationsJohn Högberg
The type annotations inserted by beam_ssa_type and beam_ssa_bsm would inadvertently disable stack trimming, as unknown instructions are considered unsafe.

2019-01-24Introduce optimizations of tail phisBjörn Gustavsson
Try to eliminate short blocks that starts with a phi node and end in a return. For example: Result = phi { Res1, 4 }, { literal true, 5 } Ret = put_tuple literal ok, Result ret Ret The code in this block can be inserted at the end blocks 4 and 5. Thus, the following code can be inserted into block 4: Ret:1 = put_tuple literal ok, Res1 ret Ret:1 And the following code into block 5: Ret:2 = put_tuple literal ok, literal true ret Ret:2 Which can be further simplified to: ret literal {ok, true} This transformation may lead to more code improvements, for example: * Stack trimming * Fewer test_heap instructions * Smaller stack frames
