2018-02-26Use overriden double/float GetHashCode for default struct hashcodes (#16550)Jan Kotas2-44/+56
Fixes #16545
2018-02-25Delete dead codeJan Kotas1-2/+0
2018-02-25Delete redundant (RuntimeType) castsJan Kotas2-48/+48
Replace `== (RuntimeType)typeof(` with `== typeof`. The type comparison is treated as JIT intrinsic and the extra cast makes the code for it worse.

2018-02-25Fix GetCustomAttribute API for DllImportAttribute pseudo custom attributeJan Kotas1-39/+33
GetCustomAttribute for DllImportAttribute was throwing IndexOutOfRangeException. It made XUnit skip the rest of test methods after encoutering DllImport method in the test type. It is regression introduced by https://github.com/dotnet/coreclr/pull/13870 Fixes https://github.com/dotnet/corefx/issues/27426

2018-02-23JIT: don't trust field offsets in R2R for nullcheck bypass (#16492)Andy Ayers1-2/+13
When the jit is forming an field address to pass off to points unknown it will nullcheck at the point of creation, unless it can prove that the field is at offset zero. Unfortunately in R2R mode field offsets may not final and so a zero value seen when prejitting may end up being nonzero when the code is loaded and fixed up and fool the jit into omitting a null check that is potentially needed. So in R2R mode, if a field offset is going to be fixed up, always emit null checks. Fixes #16454.
2018-02-23Fix preventing memory allocation in signal handler (#16485)Jan Vorlicek1-8/+5
There was a subtle bug. When the hardware exception handler returns back to the signal handler, the exception's CONTEXT record may contain modified registers and so the changes need to be propagated back to the signal context. But the recent change #16384 was restoring the signal context from the originally grabbed context instead of the one that's pointed to by the exception, which is different. I have also added a little optimization - the contextRecord that was added is not needed, since the signalContextRecord can be used as the initial context record for the exception. So we can save the contextRecord and also copying to the signalContextRecord from it.

2018-02-22Rename string-slicing extension methods (dotnet/corefx#27328)Atsushi Kanamori1-1/+1
* Rename string-slicing extension methods As part of https://github.com/dotnet/corefx/issues/26894 the api folks have approved renaming AsROSpan and AsROMemory on string instances to AsSpan and AsMemory (as the "readonly" is obvious given the read-only nature of the input.) This puts the renaming in effect. Basically a big search-replace commit. * Fix OpenSSL build break * I see this is going to be a treadmill Signed-off-by: dotnet-bot-corefx-mirror <dotnet-bot@microsoft.com>

2018-02-22Handle a restored double Interval at block boundaryCarol Eidt1-0/+6
During the process of freeing registers that are no longer live at the start of a new block, we may restore a 'previousInterval'. If that is a double (and the freed interval was float), we need to skip the next float.

Fixes: #26359 * Striping 2nd and 3rd args of PathHelper.Normalize * Build on Maryam's changes - Remove all path validity checks outside of - Null - Embedded null - Empty or all spaces (effectively empty) - Remove PathStartSkip helper - Use span overloads for StringBuffer usage - Clean up some comments * Address feedback * Tweak to match other AsSpan methods

2018-02-22Add CoreLib helpers for MemoryExtensions.AsSpan/AsMemory(T[], int) (#16505)Atsushi Kanamori2-0/+44
* Add CoreLib helpers for MemoryExtensions.AsSpan/AsMemory(T[], int) (Part of https://github.com/dotnet/corefx/issues/26894) We intentionally don't have (T[], int] constructor overloads for Span and Memory. So as not to incur unnecessary argument checks, we implement this directly in CoreLib and will invoke it from CoreFx for the fast-Span version. * Expose an internal array-int constructor instead.

Disable tiered compilation for collectible assemblies - An assembly can be marked collectible with methods not marked as dynamic - The method desc and code can be deleted and a new method desc reallocated in the same location, code versioning doesn't handle this at the moment
2018-02-21LEA on rhs of block copy can't be containedCarol Eidt2-1/+7
We don't usually create an LEA on the rhs of a block copy - we check the type of the indir, and if it's struct we avoid the copy. However, in this case, the rhs was the address of a scalar field within a struct, so the indir was not TYP_STRUCT.

2018-02-20Prevent memory allocation in signal handler (#16384)mlabiuk3-18/+54
* Do not allocate exception for signal from non managed code If the signal occurs in not managed code we cannot use heap. We should call signal-safe functions only from signal handler. Create exception object on stack for checking source of signal. If signal is from managed code we can use memory allocation to create persistent exception on heap as copy of volatile exception on stack. If signal from unmanaged code we do nothing and call base signal handler. fix https://github.com/dotnet/coreclr/issues/16338

When loading a TYP_SIMD8 local field movsd should be used, not movups. Unlike ins_Move_Extend, ins_Load does the right thing and it's consistent with indirs.
