2018-01-26Fix side effect flags setting after expression cloning. (#16045)Eugene Rozenfeld2-13/+36
Side effect flags need to be recomputed after cloning an expression, since cloning may involve some simplifications (e.g., replacing a local with a const). I also did some minor refactoring and renaming of the side-effect-updating helpers and made one of them more robust by checking whether a child is null before accessing its flags. This fixes VSO 543054 where this problem was encountered in a PMI ARM32 JitStress=2 run.

2018-01-26Fix FreeBSD build and update build instructions (#15998)Conrad Meyer2-0/+7
Move test code include in global CMakeLists before PAL runtime includes to avoid conflicts between PAL and system headers. (ForeignThreadExceptionsNative.cpp -> thread -> functional -> memory -> cassert -> pal rt "assert.h".) Drop no longer needed remove_definitions lines -- they're only set by the clrdefinitions.cmake include later in the file. Update build instructions to include needed components (ninja, lttng-ust, python27). Add missing ElfW() definition when libunwind does not define it. FreeBSD alloca() is defined in stdlib.h, so include that instead of alloca.h on FreeBSD.

2018-01-25Enable tiered jitting for R2R methods (#15967)Koundinya Veluri17-24/+395
Enable tiered jitting for R2R methods - Included R2R methods and generics over value types in CoreLib for tiered jitting. Tier 0 for R2R methods is the precompiled code if available, and tier 1 is selectively scheduled based on call counting. - Added a delay before starting to count calls for tier 1 promotion. The delay is a short duration after frequent tier 0 jitting stops (current heuristic for identifying startup). - Startup time and steady-state performance have improved on JitBench. There is a regression shortly following startup due to call counting and tier 1 jitting, for a short duration before steady-state performance stabilizes. - Added two new config values, one for configuring the call count threshold for promoting to tier 1, and another for specifying the delay from the last tier 0 JIT invocation before starting to count calls

2018-01-25Resolve iterators and async methods (#14655)Ben Adams1-3/+64
Allows a developer to determine *correct* overload called for *async* and *iterators*, from a stacktrace. Matches the compiler generated containing `Type` to the source method using: `method.DeclaringType == StateMachineAttribute.StateMachineType` attribute to allow the stack trace to resolve the mangled method name to the correct overload. Also appends the statemachine method name with `+` for iterators. Resolves: dotnet/corefx#24627

2018-01-24Disable FP to Unsigned Vector ConversionsCarol Eidt3-5/+10
The specific failure in #15848 was due to a problem with the AVX encoding of the pinsrw instruction that was exposed when AVX is enabled but AVX2 is not. The code generator generates the (SSE2) 2-operand form, but this is an instruction that needs to be encoded with the dst duplicated when using AVX encodings. So it needs to be added to `IsDstDstSrcAVXInstruction()`. Investigating this (and adding additional test coverage) revealed that conversions to FP were not implemented correctly for out-of-range values, and providing the same behavior as scalar conversion is complex and costly, with unknown benefit, as this is not expected to be a common scenario. So, don't recognize these as intrinsics (revert to the IL implementation). Also, fix the test to cover more cases. Fix 15848

2018-01-24Reflection-block some types in CoreLib (dotnet/corert#5286)Michal Strehovský1-0/+1
This saves 50 kB on a hello world app. This is using the existing ReflectionBlocked attribute to manually block public types that get otherwise blocked by the IL2IL toolchain in Project N. These types are public within the repo, but should be considered private implementation details everywhere else. Wrote a small tool that would let me identify these: https://gist.github.com/MichalStrehovsky/e2ddec899d3e0db6eba95bf68694b40e. There is more. Signed-off-by: dotnet-bot <dotnet-bot@microsoft.com>

2018-01-23Do not devirtualize shared default interface methods (#15979)Michal Strehovský1-0/+8
The result of the devirtualization for a method on a generic type should be an instantiating stub, but this doesn't seem to work right. Fixing that is a perf issue (that can be triaged/punted - #15977). This commit is a correctness fix to avoid bad codegen for that case. Resolves #15591.
2018-01-23Adjust minRegs for SELECT stress modesCarol Eidt2-40/+64
My recent refactoring to put all the `minRegCandidateCount` computation in one place failed to take into account that the `LSRA_SELECT` stress modes can also overly constrain the number of registers. Therefore, it needs to be applied only after the `minRegCandidateCount` has been computed. This may in turn cause new conflicts between the def and use of a tree temp, so factor out the code that checks for that. Fix #15932

2018-01-20Fix 64 bit shift inconsistencies (on 32 bit targets)Mike Danes4-94/+53
Recent shift changes made the JIT_LLsh helper mask the shift count to 6 bits. The other 2 helpers (JIT_LRsh and JIT_LRsz) so now we get inconsistencies such as `(x >> 64) != (x << 64)`. The ECMA spec says that "the return value is unspecified if shiftAmount is greater than or equal to the width of value" so the JIT has no obligation to implement a particular behavior. But it seems preferable to have all shift instructions behave similarly, it avoids complications and reduces risks. This also changes `ValueNumStore::EvalOpIntegral` to mask the shift count for 64 bit shifts so it matches `gtFoldExprConst`. Otherwise the produced value depends on the C/C++ compiler's behavior.
