2018-06-27Optimize Array.Clear using SpanHelpers (#18101)Jan Kotas2-33/+11
Reimplement most of Array.Clear in managed code using Span Clear helpers. Fixes dotnet/corefx#29848
2018-04-04[x86/Linux] Fix COMNumber::DoubleToNumberFC arguments order (#17412)Konstantin Baladurin2-2/+2
We should use FCDECL3_VII/FCIMPL3_VII instead of FCDECL3/FCIMPL3 otherwise we got incorrect order of arguments that leads to crashes.

2018-03-27Vectorized SequenceCompareTo for Span<char> (#17237)Jan Kotas1-38/+0
- This change makes the compare for very short Span strings a bit slower and for longer Span strings many times faster. - Switch several places where it was a clear benefit to use it. `String.CompareOrdinal(string,string)` is notable exception that I have left intact for now. It is fine tuned for current string layout, and replacing with a call of vectorized SequenceCompareTo gives mixed results.

- Simplify FCALL signatures - Simplify mantissa logic copied from corert
2017-11-28Move FormatDouble/Single to managed codeStephen Toub2-231/+6
Instead of making fcalls to FormatDouble and FormatSingle, move them to managed, and use fcalls for the DoubleToNumber and NumberToDouble they call, shifting down the layer that's implemented in native. This allows us to then much more easily add TryFormat methods for double and float while also sharing more code between coreclr and corert, from which the managed implementations were taken (they're a direct port of these native implementations from coreclr). In the process, I also eliminated one fcall that can be implemented in managed easily. The remaining fcalls are more substantial and will eventually require more effort to bring to managed.
2017-11-22Add Decimal.TryFormat span-based method (#15145)Stephen Toub4-68/+0
* Move decimal formatting to managed code - Move decimal formatting to shared (decimal itself is still not shared) - Delete VM's decimal formatting code * Add Decimal.TryFormat span-based method * Workaround ProjectN compiler bug Apply the same attribution that's applied to the code in corert. * Address PR feedback * Temporarily undo explicit layout change Seeing whether it's the cause of these failures on Unix (Ubuntu, CentOS, and OSX): ``` JIT.Directed.coverage.oldtests.lclfldadd_cs_r.lclfldadd_cs_r JIT.Directed.perffix.primitivevt.mixed1_cs_ro.mixed1_cs_ro JIT.Methodical.fp.exgen.1000w1d_cs_r.1000w1d_cs_r JIT.Methodical.fp.exgen.1000w1d_cs_ro.1000w1d_cs_ro JIT.Methodical.fp.exgen.1000w1d_cs_do.1000w1d_cs_do JIT.Methodical.fp.exgen.1000w1d_cs_d.1000w1d_cs_d JIT.Methodical.fp.exgen.10w5d_cs_d.10w5d_cs_d JIT.Methodical.fp.exgen.10w5d_cs_do.10w5d_cs_do JIT.Methodical.fp.exgen.10w5d_cs_ro.10w5d_cs_ro JIT.Methodical.fp.exgen.200w1d-02_cs_do.200w1d-02_cs_do JIT.Methodical.fp.exgen.10w5d_cs_r.10w5d_cs_r JIT.Methodical.fp.exgen.200w1d-02_cs_ro.200w1d-02_cs_ro JIT.Directed.perffix.primitivevt.mixed1_cs_do.mixed1_cs_do ``` Example failure: ``` FAILED - JIT/Methodical/fp/exgen/200w1d-02_cs_ro/200w1d-02_cs_ro.sh BEGIN EXECUTION /mnt/j/workspace/dotnet_coreclr/master/checked_ubuntu_tst_prtest/bin/tests/Windows_NT.x64.Checked/Tests/coreoverlay/corerun 200w1d-02_cs_ro.exe Unhandled Exception: System.OverflowException: Value was either too large or too small for an Int32. at System.Convert.ThrowInt32OverflowException() at System.Convert.ToInt32(Int64 value) at testout1.Func_0() at testout1.Main() ./200w1d-02_cs_ro.sh: line 243: 101339 Aborted (core dumped) $_DebuggerFullPath "$CORE_ROOT/corerun" $ExePath $CLRTestExecutionArguments Expected: 100 Actual: 134 END EXECUTION - FAILED ```
2017-11-18Remove now dead code from managed parsing/formatting.Stephen Toub2-562/+0
- Remove dead "bigNumber" code. - Remove custom wcslen function. Use String's. - Delete dead fcalls from runtime. FormatInt32, FormatUInt32, FormatInt64, and FormatUInt64 are no longer needed. Delete them and many of the helpers used only by them.

2017-10-18Use ascii * instead of Chinese * character. (#14584)Jim Ma1-3/+3
Currently we have Chinese `*` characters at `src\classlibnative\bcltype\number.cpp` L289-294. That would cause a `C4819: Non-ASCII character in source` warning when building on Windows via Visual Studio (version: 15.4.0 (msvc 19.11.25547)). This PR replaces the Chinese * characters with ascii *. Fix #14556

2017-10-02Workaround GetSystemTimePreciseAsFileTime inaccuracies (#14283)Stephen Toub1-0/+27
* Workaround GetSystemTimePreciseAsFileTime inaccuracies On misconfigured systems, GetSystemTimePreciseAsFileTime may drift quickly from GetSystemTimeAsFileTime. We want to use the former, though. As a workaround/heuristic, when checking whether we have GetSystemTimePreciseAsFileTime, invoke both and ensure they're "close", falling back to GetSystemTimeAsFileTime if it seems like the precise variant has run away. * Update comment

2017-09-12Re-implemented the ecvt function. (#12894)Jim Ma5-8/+1041
* Re-implemented the ecvt function. Instead of leveraging snprintf, re-implement the ecvt function according to the paper: https://www.cs.indiana.edu/~dyb/pubs/FP-Printing-PLDI96.pdf Note: 1. This commit won't fix any existing bug. 2. This is a raw implementation of the paper. The performance on Linux only gain 10%. We could tune the performance further. Fix #10651 * Resolve a cross platform header file issue. Fix #10651 * Fixed a minor bug. Improved the performance. Fix #10651 * Modified code according to code review feedback. This commit fixed most of the issue found in code review. However, some of the feedback may not be involved due to either little performance improvement or need a POC. Fix #10651 * Try to fix constexpr compile error on Windows. Fix #10651 * Fixed a potential overflow bug in BigNum::Compare. Fix #10651 * Improved multiply 10 operation. Use shift and add operation to replace actual multiply operation. Fix #10651 * Remove old _ecvt function. Fix #10651 * Documented the reason why we do not need m+ and m-. Fix #10651 * Changed exp > 0 to exp != 0 to remove any confusion. exp should fall in 1 ~ 2046 for normalized value. Denormalized value has exp = 0. Fix #10651 * Disable the _ecvt tests. Fix #10651 * Removed _ecvt tests. Fix #10651 * Re-implemented LogBase2. Fix #10651 * Use DWORD and DWORD64 for _BitScanReverse and _BitScanReverse64 Fix #10651 * Fixed x86 compile issue for _BitScanReverse64 x86 does not support _BitScanReverse64 so we have to add additional shift operations to handle it. Fix #10651 * Implemented BitScanReverse64 and BitScanReverse in pal.h Fix #10651 * Remove the confusion comment which is unrelated to BitScanReverse. Fix #10651 * Introduced wmemset to enhance the perf for 0.0 Fix #10651 * Improved the performance of converting 0.0. Fix #10651 * Renamed ecvt to DoubleToNumberWorker. Fix #10651 * Updated code according to the code review feedback. Fix #10651
