* testsuite: Don't crash on encoding failure in printBen Gamari2020-01-241-2/+6
| | | | | | If the user doesn't use a Unicode locale then the testsuite driver would previously throw framework failures due to encoding failures. We now rather use the `replace` error-handling strategy.
* testsuite: Preserve more information in framework failuresBen Gamari2020-01-201-1/+1
| | | | | Namely print the entire exception in hopes that this will help track down #17649.
* Fix more typos, via an improved Levenshtein-style correctorBrian Wignall2020-01-121-1/+1

* testsuite: Fix Windows platform testBen Gamari2020-01-071-2/+1
| | | | | | | | Previously we used platform.system() and while this worked fine (e.g. returned `Windows`, as expected) locally under both msys and MingW64 Python distributions, it inexplicably returned `MINGW64_NT-10.0` under MingW64 Python on CI. It seems os.name is more reliable so we now use that instead..

* perf_notes: Add --zero-y argumentBen Gamari2019-12-301-12/+25
| | | | | This makes it easier to see the true magnitude of fluctuations. Also do some house-keeping in the argument parsing department.
* testsuite: Simplify and clarify performance test baseline searchBen Gamari2019-12-123-69/+48
| | | | | | | The previous implementation was extremely complicated, seemingly to allow the local and CI namespaces to be searched incrementally. However, it's quite unclear why this is needed and moreover the implementation seems to have had quadratic runtime cost in the search depth(!).
* Implement pointer tagging for big families (#14373)Gabor Greif2019-12-061-2/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Formerly we punted on these and evaluated constructors always got a tag of 1. We now cascade switches because we have to check the tag first and when it is MAX_PTR_TAG then get the precise tag from the info table and switch on that. The only technically tricky part is that the default case needs (logical) duplication. To do this we emit an extra label for it and branch to that from the second switch. This avoids duplicated codegen. Here's a simple example of the new code gen: data D = D1 | D2 | D3 | D4 | D5 | D6 | D7 | D8 On a 64-bit system previously all constructors would be tagged 1. With the new code gen D7 and D8 are tagged 7: [Lib.D7_con_entry() { ... {offset c1eu: // global R1 = R1 + 7; call (P64[Sp])(R1) args: 8, res: 0, upd: 8; } }] [Lib.D8_con_entry() { ... {offset c1ez: // global R1 = R1 + 7; call (P64[Sp])(R1) args: 8, res: 0, upd: 8; } }] When switching we now look at the info table only when the tag is 7. For example, if we derive Enum for the type above, the Cmm looks like this: c2Le: _s2Js::P64 = R1; _c2Lq::P64 = _s2Js::P64 & 7; switch [1 .. 7] _c2Lq::P64 { case 1 : goto c2Lk; case 2 : goto c2Ll; case 3 : goto c2Lm; case 4 : goto c2Ln; case 5 : goto c2Lo; case 6 : goto c2Lp; case 7 : goto c2Lj; } // Read info table for tag c2Lj: _c2Lv::I64 = %MO_UU_Conv_W32_W64(I32[I64[_s2Js::P64 & (-8)] - 4]); if (_c2Lv::I64 != 6) goto c2Lu; else goto c2Lt; Generated Cmm sizes do not change too much, but binaries are very slightly larger, due to the fact that the new instructions are longer in encoded form. E.g. previously entry code for D8 above would be 00000000000001c0 <Lib_D8_con_info>: 1c0: 48 ff c3 inc %rbx 1c3: ff 65 00 jmpq *0x0(%rbp) With this patch 00000000000001d0 <Lib_D8_con_info>: 1d0: 48 83 c3 07 add $0x7,%rbx 1d4: ff 65 00 jmpq *0x0(%rbp) This is one byte longer. Secondly, reading info table directly and then switching is shorter _c1co: movq -1(%rbx),%rax movl -4(%rax),%eax // Switch on info table tag jmp *_n1d5(,%rax,8) than doing the same switch, and then for the tag 7 doing another switch: // When tag is 7 _c1ct: andq $-8,%rbx movq (%rbx),%rax movl -4(%rax),%eax // Switch on info table tag ... Some changes of binary sizes in actual programs: - In NoFib the worst case is 0.1% increase in benchmark "parser" (see NoFib results below). All programs get slightly larger. - Stage 2 compiler size does not change. - In "containers" (the library) size of all object files increases 0.0005%. Size of the test program "bitqueue-properties" increases 0.03%. nofib benchmarks kindly provided by Ömer (@osa1): NoFib Results =============

* testsuite: don't collect compiler stats in collect_runtime_residencyAlp Mestanogullari2019-11-121-1/+1
| | | | | | | | | | | | | | | | | | | We instead want to collect the runtime stats (with collect_stats, instead of collect_compiler_stats). This should fix a number of perf tests failures we have been seeing, where we suddenly started measuring metrics we didn't intend to measure, which tend to fall outside of the acceptance window. Metric Decrease: lazy-bs-alloc T3586 Metric Increase: space_leak_001 T4801 T5835 T12791
* testsuite: Don't check_stats at runtime if not requestedwip/T17387Ben Gamari2019-11-101-4/+9
| | | | | | Previously we would call check_stats to check the runtime metrics even if the test definition hadn't requested it. This would result in an error since the .stats file doesn't exist.

* testsuite: Assert that testsuite ways are knownBen Gamari2019-10-171-28/+49
| | | | | This ensures that all testsuite way names given to `omit_ways`, `only_ways`, etc. are known ways.
* testsuite: Ensure that makefile tests get runBen Gamari2019-10-171-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously `makefile_test` and `run_command` tests could easily end up in a situation where they wouldn't be run if the user used the `only_ways` modifier. The reason is to build the set of a ways to run the test in we first start with a candidate set determined by the test type (e.g. `makefile_test`, `compile_run`, etc.) and then filter that set with the constraints given by the test's modifiers. `makefile_test` and `run_command` tests' candidate sets were simply `{normal}`, and consequently most uses of `only_ways` would result in the test being never run. To avoid this we rather use all ways as the candidate sets for these test types. This may result in a few more testcases than we would like (given that some `run_command` tests are insensitive to way) but this can be fixed by adding modifiers and we would much rather run too many tests than too few. This fixes #16042 and a number of other tests afflicted by the same issue. However, there were a few cases that required special attention: * `T14028` is currently failing and is therefore marked as broken due to #17300 * `T-signals-child` is fragile in the `threaded1` and `threaded2` ways (tracked in #17307)
* Use os.devnull instead of '/dev/null' in the testsuite driver.Andreas Klebinger2019-08-141-4/+26
| | | | | | | | | | | | The later caused issues on windows by being translated into "\\dev\\null" and python then trying to open this non-existant file. So we now use os.devnull inside python and convert it to "/dev/null" when calling out to the shell, which is bound to run in a unix like environment. This fixes an issue a test producing unexpected stderr output failed with a framework failure instead of showing a diff of the output.

* Testsuite tweaks and refactoringÖmer Sinan Ağacan2019-07-091-8/+10
| | | | | | | | | | | | | | | | - Rename requires_th to req_th for consistency with other req functions (e.g. req_interp, req_profiling etc.) - req_th (previously requires_th) now checks for interpreter (via req_interp). With this running TH tests are skipped when running the test suite with stage=1. - Test tweaks: - T9360a, T9360b: Use req_interp - recomp009, T13938, RAE_T32a: Use req_th - Fix check-makefiles linter: it now looks for Makefiles instead of .T files (which are actually Python files)

* testsuite: Add assertions that way lists are in fact listsBen Gamari2019-06-151-0/+6
| | | | | | Previously there were a few cases where operations like `omit_ways` were incorrectly passed a single way (e.g. `omit_ways('threaded2')`). This won't work as the author expected.

I also simplified the text output to use the same data as the chart. You can now use a commit range with git's ".." syntax. The --ci option will use results from CI (you'll need to fetch them first): $ git fetch https://gitlab.haskell.org/ghc/ghc-performance-notes.git refs/notes/perf:refs/notes/ci/perf $ python3 testsuite/driver/perf_notes.py --ci --chart --test-env x86_64-darwin --test-name T9630 master~500..master
* testsuite: introduce 'static_stats' testsAlp Mestanogullari2019-05-292-5/+16
| | | | | | | | | | | | | | | | They are a particular type of perf tests. This patch introduces a 'stats_files_dir' configuration field in the testsuite driver where all haddock timing files (and possibly others in the future) are assumed to live. We also change both the Make and Hadrian build systems to pass respectively $(TOP)/testsuite/tests/perf/haddock/ and <build root>/stage1/haddock-timing-files/ as the value of that new configuration field, and to generate the timing files in those directories in the first place while generating documentation with haddock. This new test type can be seen as one dedicated to examining stats files that are generated while building a GHC distribution. This also lets us get rid of the 'extra_files' directives in the all.T entries for haddock.base, haddock.Cabal and haddock.compiler.
* Improve test runner logging when calculating performance metric baseline #16662David Eichmann2019-05-201-5/+16
| | | | | | We attempt to get 75 commit hashes via `git log`, but this only gave 10 hashes in a CI run (see #16662). Better logging may help solve this error if it occurs again in the future.
* Update terminal title while running test-suiteOleg Grenrus2019-05-143-4/+30
| | | | | Useful progress indicator even when `make test VERBOSE=1`, and when you do something else, but have terminal title visible.
* codegen: fix memset unroll for small bytearrays, add 64-bit setsArtem Pyanykh2019-04-091-2/+57
| | | | | | | | | | | | | | | | | | | | | | Fixes #16052 When the offset in `setByteArray#` is statically known, we can provide better alignment guarantees then just 1 byte. Also, memset can now do 64-bit wide sets. The current memset intrinsic is not optimal however and can be improved for the case when we know that we deal with (baseAddress at known alignment) + offset For instance, on 64-bit `setByteArray# s 1# 23# 0#` given that bytearray is 8 bytes aligned could be unrolled into `movb, movw, movl, movq, movq`; but currently it is `movb x23` since alignment of 1 is all we can embed into MO_Memset op.
