7 years agoAdd optimization for shift by CNS_INT
Michelle McDaniel [Fri, 9 Sep 2016 17:44:03 +0000 (10:44 -0700)]
Add optimization for shift by CNS_INT

This change adds support for shifting by a GT_CNS_INT without going
through a helper. If the shiftOp is a GT_CNS_INT we do several
transformations based on the shift amount:

If the shift amount is 0, the shift is a nop, so we just put together the
hi and lo ops as a GT_LONG.

If the shift amount is < 32, we generate a shl/shld pattern, a shr/shrd
pattern or a sar/shrd pattern, depending on the oper. The first operand of
the shrd/shld is a GT_LONG, which we crack in codegen, using it
essentially as two int operands, rather than creating a tri op GenTree
node (essentially so that we can have 3 operands, instead of the normal
two).

If the shift amount is 32, it differs between shifting left and shifting
right. For GT_LSH, we move the loOp into the hiResult and set the loResult
to 0. For GT_RSZ, we move the hiOp into the loResult, and set the hiResult
to 0. For GT_RSH, we move the hiOp into the loResult, and set the hiResult
to a 31 bit signed shift of the hiOp to sign extend.

If the shift amount is less than 64, but larger than 32: for GT_LSH, the
hiResult is a shift of the loOp by shift amount - 32 (the move from lo into hi is
the 32 bit shift). We set the loResult to 0. For GT_RSH and GT_RSZ, the
loResult is a right shift (signed for GT_RSH) of the hiOp by shift amount
- 32. The hiResult is 0 for GT_RSZ, and a 31 bit signed shift of hiOp1 for
GT_RSH.

If the shift amount is >= 64, we set both hiResult and loResult to 0 for
GT_LSH and GT_RSZ, and do a sign extend shift to set hiResult and loResult
to the sign of the original hiOp for GT_RSH.

in the call's argument table must be replaced. Managing this replacement
was a bit ad-hoc: there were a (small) number of places throughout the
compiler that needed to do so, and each determined whether or not to
call the udpate method (`fgFixupArgTabEntryPtr`) independently. The
update method has been removed and its functionality replaced with a
new method, `GenTree::ReplaceOperand`, which will update the call
argument table iff the replaced node is a call argument.

Introduce GT_JCC.

This node represents a jump that is conditional upon the value stored in
the target's condition code register. It is only valid in the backend.
No formal modeling of the CCR is performed, so its use must be
constrained such that instructions that def the CCR are not inserted
between the JCC node and the node that it expected to def the CCR.

This is currently only used when lowering compares of long-typed
values for x86.

7 years agoImplement long compare lowering for x86.
Mike Danes [Thu, 8 Sep 2016 11:54:14 +0000 (14:54 +0300)]
Implement long compare lowering for x86.

Comparisons between long-typed values on x86 require at least two and
at most three separate branches: one or two to compare the high 32
bits and one to compare the low 32 bits. In essence, each long
compare introduces two additional basic blocks into the flow graph,
but these blocks were not reified until code generation. Furthermore,
code generation of a long comparison used by a JTRUE was deferred
until the JTRUE itself without marking the inputs to the compare as
live at the JTRUE. Taken together, these representational issues
caused bugs like the one seen in the the following assembly:

       33DB         xor      ebx, ebx
       BE03000000   mov      esi, 3
       33FF         xor      edi, edi
       8B75F0       mov      esi, dword ptr [ebp-10H] ; these 2 are reloads inserted by LSRA
       8B7DEC       mov      edi, dword ptr [ebp-14H] ; between the compare and the branch
       3BDF         cmp      ebx, edi
       72D6         jb       SHORT G_M51005_IG03
       7704         ja       SHORT G_M51005_IG04
       3BC6         cmp      eax, esi
       72D0         jb       SHORT G_M51005_IG03

The reloads that LSRA has inserted have killed the registers assigned
to the inputs to the compare, thus causing the compare instructions
to read unexpected values (GH dotnet/coreclr#7038).

Although a number of alternatives were discussed, the best solution
seems to be to expose the control flow via the flow graph rather than
leaving it until code generation; this commit implements that approach.

Implement GcInfo v2 for X86

This commit includes the following changes:
1) Thread GcInfo version through X86 specific APIs
2) Add ReturnKind and ReversePinvokeOffset fields to InfoHdr structure
   GcInfo v1 and v2 use the same InfoHdr structures, because:
   InfoHdrSmall: ReturnKind is encoded within previously unused bits.
   InfoHdr: revPInvokeOffset will never be written to the image,
            since ReversePinvokeOffset==INVALID_REV_PINVOKE_OFFSET for V1.
3) Update the Pre-computed header table to include bits for the above
   [The default setting of ReturnKind=RT_Scalar is used for all entries in the table.
    Optimizing this table based in most frequent usage scenarios is to be done separately]
4) Change the GC encoder/decoder to handle the above two fields
5) Use the ReturnKind in the GCInfo from thread-suspension code.

To maintain source compatibilty, `Split(string)` has been removed,
leaving just the overloads with `StringSplitOptions` parameters, which

`Split(null)` which still binds to `Split(char[])` in C#, VB, and F#.

result will be an int. Therefore, in decompose, we change the type of the
GT_UMOD to be TYP_INT, and replace op2 with its lo part. We set the high
part of the GT_LONG to be 0, since the divisor < 0x3fffffff. In lower, we need
to make sure that loOp1 is in RAX and hiOp1 is in RDX, which is where
idiv expects them to be. We also increase the number of sources since
there are now three sources. In codegen, we need to make sure that the hi

RyuJIT x86: Implement GS cookie check for functions with tailcall

Fixes dotnet/coreclr#7086, one of the most common asserts in stress runs.

I moved some helper code from the legacy codegen to codegencommon
so it could be used. I also added the code to generate the GS
cookie check for tailcall via helper code (on x64, we never
generate GS cookie checks when there are tailcalls).

Restrict x86 legacy JIT struct promotion

Don't allow struct promotion for custom layout structs. RyuJIT started
supporting this, but the legacy x86 JIT doesn't properly push such promoted
structs as arguments for calls.

Fixes the assert in dotnet/coreclr#7127, but the test fails with a crash in a later test case.
