  Recommit "Use ValueOffsetPair to enhance value reuse during SCEV
  expansion".

  The fix for PR28705 will be committed consecutively.

  In D12090, the ExprValueMap was added to reuse existing value during
  SCEV expansion. However, const folding and sext/zext distribution can
  make the reuse still difficult.

  A simplified case is: suppose we know S1 expands to V1 in
  ExprValueMap, and
    S1 = S2 + C_a
    S3 = S2 + C_b
  where C_a and C_b are different SCEVConstants. Then we'd like to
  expand S3 as V1 - C_a + C_b instead of expanding S2 literally. It is
  helpful when S2 is a complex SCEV expr and S2 has no entry in
  ExprValueMap, which is usually caused by the fact that S3 is
  generated from S1 after const folding.

  In order to do that, we represent ExprValueMap as a mapping from SCEV
  to ValueOffsetPair. We will save both S1->{V1, 0} and S2->{V1, C_a}
  into the ExprValueMap when we create SCEV for V1. When S3 is
  expanded, it will first expand S2 to V1 - C_a because of S2->{V1,
  C_a} in the map, then expand S3 to V1 - C_a + C_b.

Pull in r276136 from upstream llvm trunk (by Wei Mi):

  Use ValueOffsetPair to enhance value reuse during SCEV expansion.

  In D12090, the ExprValueMap was added to reuse existing value during
  SCEV expansion. However, const folding and sext/zext distribution can
  make the reuse still difficult.

  A simplified case is: suppose we know S1 expands to V1 in
  ExprValueMap, and
    S1 = S2 + C_a
    S3 = S2 + C_b
  where C_a and C_b are different SCEVConstants. Then we'd like to
  expand S3 as V1 - C_a + C_b instead of expanding S2 literally. It is
  helpful when S2 is a complex SCEV expr and S2 has no entry in
  ExprValueMap, which is usually caused by the fact that S3 is
  generated from S1 after const folding.

  In order to do that, we represent ExprValueMap as a mapping from SCEV
  to ValueOffsetPair. We will save both S1->{V1, 0} and S2->{V1, C_a}
  into the ExprValueMap when we create SCEV for V1. When S3 is
  expanded, it will first expand S2 to V1 - C_a because of S2->{V1,
  C_a} in the map, then expand S3 to V1 - C_a + C_b.

Fix the error value we write in cerror. __error returns an int *, however
we were writing a 64 bit value meaning the 32 bits after this would be
trashed.

Use time_t for intermediate values to avoid overflow in clock_ts_to_ct

Add additionally safety and overflow checks to clock_ts_to_ct and the
BCD routines while we're here.

Perform a safety check in sys_clock_settime() first to avoid easy local
root panic, without having to propagate an error value back through
dozens of APIs currently lacking error returns.

7 years agoMake CTL ramdisk backend a real RAM disk.
mav [Tue, 24 Jan 2017 12:13:41 +0000 (12:13 +0000)]
Make CTL ramdisk backend a real RAM disk.

If "capacity" LU option is set, ramdisk backend now implements featured
thin provisioned disk, storing data in malloc(9) allocated memory blocks
of pblocksize bytes (default PAGE_SIZE or 4KB).  Additionally ~0.2% of LU
size is used for indirection tree (bigger pblocksize reduce the overhead).
Backend supports all unmap and anchor operations.  If configured capacity
is overflowed, proper error conditions are reported.

If "capacity" LU option is not set, the backend operates mostly the same
as before without allocating real storage: writes go to nowhere, reads
return zeroes, reporting that all LBAs are unmapped.

This backend is still mostly oriented on testing and benchmarking (it is
still a volatile RAM disk), but now it should allow to run real FS tests,
not only simple dumb dd.
