Fix consume-order checking in codegen.

The switch to LIR invalidated the correspondence between a node's
sequence number and the order in which it must be consumed with respect
to other nodes. This in turn made the consume-order checks during code
generation incorrect.

This change introduces a new field, `gtUseNum`, that is used during code
generation to check the order in which nodes are consumed. Re-enabling
these checks revealed a bug in code generation for locked instructions
on x86, which were consuming their operands out-of-order; this change
also contains a fix for that bug.

The original CoreRT implementation just dropped the current table and replaced it with a new one.  In the process of porting the CoreRT implementation to CoreCLR, I'd changed it to instead remove each item from the table (by setting its hashcode to -1, as does Remove), in order to work around some code in the finalizer that would null out te parent's reference to the container, and that would cause problems with dropping this table... but that code in the finalizer changed before it got merged, and in its current form, the old CoreRT clear implementation was fine.  It's also likely better, as it'll let the handles be cleaned up earlier, and it's simple.  So reverting back to it.

7 years agoFix perf regression with lots of objects in a ConditionalWeakTable
Stephen Toub [Wed, 7 Dec 2016 21:35:03 +0000 (16:35 -0500)]
Fix perf regression with lots of objects in a ConditionalWeakTable

The CoreRT implementation of ConditionalWeakTable that was ported back to CoreCLR uses a special scheme to make reads lock-free.  When the container needs to grow, it allocates new arrays and duplicates all of the dependency handles from the previous array, rather than just copying them.  This avoids issues stemming from a thread getting a dependency handle in an operation on the container, then having that handle destroyed, and then trying to use it; the handle won't be destroyed as long as the container is referenced.

However, this also leads to a significant cost in a certain situation.  Every time the container grows, it allocates another N dependency handles where N is the current size of the container.  So, for example, with an initial size of 8, if 64 objects are added to the container, it'll allocate 8 dependency handles, then another 16, then another 32, and then another 64, resulting in significantly more handles than in the old implementation, which would only allocate 64 handles total.

This commit fixes that by changing the scheme slightly.  A container still frees its handles in its finalizer.  However, rather than duplicating all handles, that responsibility for freeing is transferred from one container to the next.  Then to avoid issues where, for example, the second container is released while the first is still in use, a reference is maintained from the first to the second, so that the second can't be finalized while the first is still in use.

The commit also fixes a race condition with resurrection and finalization, whereby dependency handles could be used while or after they're being freed by the finalizer. It's addressed by only freeing handles in a second finalization after clearing out state in the first finalization to guarantee no possible usage during the second.

Correct an assertion in LSRA.

`verifyFinalAllocation` asserts that if a non-BB interval RefPosition
that is either spilled or is the interval's last use does not have a
register, then that ref position must be marked `AllocateIfProfitable`.
However, this situation can also arise in at least one other situation:
an unused parameter will have at least one ref position that may not be
allocated to a register. This change corrects the assertion to check
`RefPosition::RequiresRegister` rather than
`RefPosition::AllocateIfProfitable`.

Fixes VSO 299207.

7 years agoDisable special put args for LIMIT_CALLER on x86.
Pat Gavlin [Thu, 8 Dec 2016 22:14:38 +0000 (14:14 -0800)]
Disable special put args for LIMIT_CALLER on x86.

On x86, `LSRA_LIMIT_CALLER` is too restrictive to allow the use of special
put args: this stress mode leaves only three registers allocatable--eax,
ecx, and edx--of which the latter two are also used for the first two
integral arguments to a call. This can leave us with too few registers to
succesfully allocate in situations like the following:

    t1026 =    lclVar    ref    V52 tmp35        u:3 REG NA <l:$3a1, c:$98d>

            /--*  t1026  ref
    t1352 = *  putarg_reg ref    REG NA

     t342 =    lclVar    int    V14 loc6         u:4 REG NA $50c

     t343 =    const     int    1 REG NA $41

            /--*  t342   int
            +--*  t343   int
     t344 = *  +         int    REG NA $495

     t345 =    lclVar    int    V04 arg4         u:2 REG NA $100

            /--*  t344   int
            +--*  t345   int
     t346 = *  %         int    REG NA $496

            /--*  t346   int
    t1353 = *  putarg_reg int    REG NA

    t1354 =    lclVar    ref    V52 tmp35         (last use) REG NA

            /--*  t1354  ref
    t1355 = *  lea(b+0)  byref  REG NA

Here, the first `putarg_reg` would normally be considered a special put arg,
which would remove `ecx` from the set of allocatable registers, leaving
only `eax` and `edx`. The allocator will then fail to allocate a register
for the def of `t345` if arg4 is not a register candidate: the corresponding
ref position will be constrained to { `ecx`, `ebx`, `esi`, `edi` }, which
`LSRA_LIMIT_CALLER` will further constrain to `ecx`, which will not be
available due to the special put arg.
