2017-03-06hipe: Improve code generation for element/2Magnus Lång
* Omit bounds check in more cases. A test case that needs this change to omit bounds check is added. * Improve code generation by reformulating bounds check to decrease register pressure.

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.

2016-08-30hipe: 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.

This is required in some really old SPARC machines running Solaris we still have access to.

2016-05-23hipe: Add test suite for verifying optimisationsErik Norgren
* Added a suite opt_verify_SUITE.erl to HiPE that tests for the results of optimisations, with a single testcase that checks that the icode_call_elim optimisation pass does remove calls to maps:is_key/2 where sound and not otherwise. * Made hipe_testsuite_driver only create explicitly listed suites.
2016-05-04Up the limit for the timetrap used in the HiPE testsuiteKostis Sagonas
Without this change, one test (bs_utf) times out when run on some very slow SUN/SPARC machine we still have around. Unfortunately, this is the only such machine that we have access to these days. Perhaps suprisingly, all the HiPE tests pass on SPARC, which is nice to know that this backend still works, despite not having been tested for more than one (almost two?) years now.
2016-05-03One more test suite for binary pattern matchingKostis Sagonas
Taken from the OTP test suites and changed accordingly for HiPE. Used to be problematic in the tests that matched against a segment of 'bad_size'. This was corrected in the BEAM compiler for OTP 19.

2016-03-02hipe: Fix crashing bugs when inlining FP opsMagnus Lång
It was assumed in hipe_icode_fp:filter_map/3 that either all predecessors would have an up-to-date ("assigned") tagged copy, or none of them. This is temporarily false during the fixpoint loop in basic_floats:test_icode_type_crash_2/0, which exercises the all_args_equal(Bindings) =:= true branch, that would previously erroneously end up in the 'false' branch, which is what caused the crash in that case. This is likewise only temporarily false during the fixpoint loop in basic_floats:test_icode_type_crash/0, but that case instead exercises the 'false' branch, justifying the inclusion of both tests.

2016-02-17Makefiles: Remove test_server from include path and code pathBjörn Gustavsson
Since no test suites includede test_server.hrl, there is no need to have test_server in the include path or code path.
2016-02-17Eliminate use of test_server.hrl and test_server_line.hrlBjörn Gustavsson
As a first step to removing the test_server application as as its own separate application, change the inclusion of test_server.hrl to an inclusion of ct.hrl and remove the inclusion of test_server_line.hrl.

2015-12-16Fix compilation of matching with UTF binariesKostis Sagonas
The code generated by the HiPE compiler for pattern matching with UTF binaries was such that sometimes THE_NON_VALUE was stored in the roots followed by the garbage collector. This was not an issue for the vanilla native code compiler, but was problematic for the ErLLVM back-end. Fix the issue by not storing THE_NON_VALUE in the live roots. An alternative fix would be to change the code of the garbage collector. With this fix, there are no more (known) failing test cases for the ErLLVM back-end (at least on x86_64 with LLVM 3.5, which is the configuation regularly tested). Thanks to @margnus1 for the fix.

2015-12-02hipe: Fix signed compares of unsigned sizesMagnus Lång
Also, some of the branches were testing sizes in bits against a constant ?MAX_BINSIZE, which was in bytes. The signed comparisons masked this mistake. These branches have been removed since all sizes in bits that fit in a machine word are valid binary sizes. Finally, a test that reproduces the issue was added to bs_construct, along with a test for one of the cases (bs_init<0>(...)) when the test against ?MAX_BINSIZE must be changed to unsigned rather than removed.

2015-11-27Add a case testing the handling of guards involving binariesKostis Sagonas
The HiPE compiler was leaking exceptions out of guards involving binaries with `strange' arithmetic in them. Fixed by the set of changes in this pull request.
2015-11-27Add some more binary syntax construction testsKostis Sagonas
Some more cases (taken from the BEAM bs_construct suite) that used to show different behaviour than BEAM when compiled to native code were included in the appropriate test file of the HiPE test suite.

2015-10-12Fix edge case of Size = 0 in bs_put_integerKostis Sagonas
copy_offset_int_big was assuming (Offset + Size - 1) (Tmp9 in the first BB) would not underflow. It was also unconditionally reading and writing the binary even when Size was zero, unlike copy_int_little, which is the only other case of bs_put_integer that does not have a short-circuit on Size = 0. This was causing segfaults when constructing binaries starting with a zero-length integer field, because a logical right shift was used to compute an offset in bytes (which became 0x1fffffffffffffff) to read in the binary. Tests, taken from the emulator bs_construct_SUITE, were also added. The complete credit for the report and the fix goes to Magnus Lång.
2015-10-02Fix matching with huge binariesKostis Sagonas
In certain cases of matching with very big binaries, the HiPE compiler generated code that would fail the match, even in cases that the matching was successful. The problem was more quite noticeable on 32-bit platforms where certain integer quantities would be represented as bignums. Brief summary of changes: * gen_rtl({bs_skip_bits, ...}, ...) could not handle too large constants. Previously the constants were truncated to word size. * hipe_rtl_binary_match:make_size/3 erroneously assumed that the output of first_part/3 would not overflow when multiplied by 8, which is no longer true. To maintain full performance, the overflow test is only performed when BitsVar was a bignum. Thus, the fast path is identical to before. * hipe_rtl_binary_match:set_high/2 was assuming that only bits below bit 27 were ever set in arguments to bs_skip_bits, which is not only false when the arguments are bignums, but also on 64-bit platforms. The commit includes a test taken from the bs_match_bin_SUITE. Most of the credit for finding these HiPE compiler errors and for creating appropriate fixes for them should go to Magnus Lång.
