8 years ago[WinEH] Let cleanups post-dominated by unreachable get executed
David Majnemer [Fri, 22 Jan 2016 23:20:43 +0000 (23:20 +0000)]
[WinEH] Let cleanups post-dominated by unreachable get executed

Cleanups in C++ are a little weird.  They are only guaranteed to be
reliably executed if, and only if, there is a viable catch handler which
can handle the exception.

This means that reachability of a cleanup is lexically determined by it
being nested with a try-block which unwinds to a catch.  It is *cannot*
be reasoned about by examining the control flow edges leaving a cleanup.

Usually this is not a problem.  It becomes a problem when there are *no*
edges out of a cleanup because we believed that code post-dominated by
the cleanup is dead.  In LLVM's case, this code is what informs the
personality routine about the presence of a suitable catch handler.
However, the lack of edges to that catch handler makes the handler
become unreachable which causes us to remove it.  By removing the
handler, the cleanup becomes unreachable.

Instead, inject a catch-all handler with every cleanup that has no
unwind edges.  This will allow us to properly unwind the stack.

This fixes PR25997.

8 years agoFix the code that leads to the incorrect trigger of the report_fatal_error()
Kevin Enderby [Fri, 22 Jan 2016 22:49:55 +0000 (22:49 +0000)]
Fix the code that leads to the incorrect trigger of the report_fatal_error()
in MachOObjectFile::getSymbolByIndex() when a Mach-O file has
a symbol table load command but the number of symbols are zero.

The code in MachOObjectFile::symbol_begin_impl() should not be
assuming there is a symbol at index 0, in cases there is no symbol
table load command or the count of symbol is zero.  So I also fixed
that.  And needed to fix MachOObjectFile::symbol_end_impl() to
also do the same thing for no symbol table or one with zero entries.

The code in MachOObjectFile::getSymbolByIndex() should trigger
the report_fatal_error() for programmatic errors for any index when
there is no symbol table load command and not return the end iterator.
So also fixed that. Note there is no test case as this is a programmatic
error.

The test case using the file macho-invalid-bad-symbol-index has
a symbol table load command with its number of symbols (nsyms)
is zero. Which was incorrectly testing the bad triggering of the
report_fatal_error() in in MachOObjectFile::getSymbolByIndex().

This test case is an invalid Mach-O file but not for that reason.
It appears this Mach-O file use to have an nsyms value of 11,
and what makes this Mach-O file invalid is the counts and
indexes into the symbol table of the dynamic load command
are now invalid because the number of symbol table entries
(nsyms) is now zero.  Which can be seen with the existing
llvm-obdump:

% llvm-objdump -private-headers macho-invalid-bad-symbol-index

Load command 4
     cmd LC_SYMTAB
 cmdsize 24
  symoff 4216
   nsyms 0
  stroff 4392
 strsize 144
Load command 5
            cmd LC_DYSYMTAB
        cmdsize 80
      ilocalsym 0
      nlocalsym 8 (past the end of the symbol table)
     iextdefsym 8 (greater than the number of symbols)
     nextdefsym 2 (past the end of the symbol table)
      iundefsym 10 (greater than the number of symbols)
      nundefsym 1 (past the end of the symbol table)
...

And the native darwin tools generates an error for this file:

% nm macho-invalid-bad-symbol-index
nm: object: macho-invalid-bad-symbol-index truncated or malformed object (ilocalsym plus nlocalsym in LC_DYSYMTAB load command extends past the end of the symbol table)

I added new checks for the indexes and sizes for these in the
constructor of MachOObjectFile.  And added comments for what
would be a proper diagnostic messages.

And changed the test case using macho-invalid-bad-symbol-index
to test for the new error now produced.

Also added a test with a valid Mach-O file with a symbol table
load command where the number of symbols is zero that shows
the report_fatal_error() is not called.

8 years ago[AArch64] Lower 2-CC FCCMPs (one/ueq) using AND'ed CCs.
Ahmed Bougacha [Fri, 22 Jan 2016 19:43:54 +0000 (19:43 +0000)]
[AArch64] Lower 2-CC FCCMPs (one/ueq) using AND'ed CCs.

The current behavior is incorrect, as the two CCs returned by
changeFPCCToAArch64CC, intended to be OR'ed, are instead used
in an AND ccmp chain.

Consider:
define i32 @t(float %a, float %b, float %c, float %d, i32 %e, i32 %f) {
  %cc1 = fcmp one float %a, %b
  %cc2 = fcmp olt float %c, %d
  %and = and i1 %cc1, %cc2
  %r = select i1 %and, i32 %e, i32 %f
  ret i32 %r
}

Assuming (%a < %b) and (%c < %d); we used to do:
  fcmp  s0, s1            # nzcv <- 1000
  orr   w8, wzr, #0x1     # w8 <- 1
  csel  w9, w8, wzr, mi   # w9 <- 1
  csel  w8, w8, w9, gt    # w8 <- 1
  fcmp  s2, s3            # nzcv <- 1000
  cset   w9, mi           # w9 <- 1
  tst    w8, w9           # (w8 & w9) == 1, so: nzcv <- 0000
  csel  w0, w0, w1, ne    # w0 <- w0

We now do:
  fcmp  s2, s3            # nzcv <- 1000
  fccmp s0, s1, #0, mi    #  mi, so: nzcv <- 1000
  fccmp s0, s1, #8, le    # !le, so: nzcv <- 1000
  csel  w0, w0, w1, pl    # !pl, so: w0 <- w1

In other words, we transformed:
  (c < d) &&  ((a < b) || (a > b))
into:
  (c < d) &&   (a u>= b) && (a u<= b)
whereas, per De Morgan's, we wanted:
  (c < d) && !((a u>= b) && (a u<= b))

Note that this problem doesn't occur in the test-suite.

changeFPCCToAArch64CC produces disjunct CCs; here, one -> mi/gt.
We can't represent that in the fccmp chain; it can't express
arbitrary OR sequences, as one comment explains:
  In general we can create code for arbitrary "... (and (and A B) C)"
  sequences.  We can also implement some "or" expressions, because
  "(or A B)" is equivalent to "not (and (not A) (not B))" and we can
  implement some  negation operations. [...] However there is no way
  to negate the result of a partial sequence.

Instead, introduce changeFPCCToANDAArch64CC, which produces the
conjunct cond codes:
- (a one b)
    == ((a olt b) || (a ogt b))
    == ((a ord b) && (a une b))
- (a ueq b)
    == ((a uno b) || (a oeq b))
    == ((a ule b) && (a uge b))

Note that, at first, one might think that, when PushNegate is true,
we should use the disjunct CCs, in effect doing:
  (a || b)
  = !(!a && !(b))
  = !(!a && !(b1 || b2))  <- changeFPCCToAArch64CC(b, b1, b2)
  = !(!a && !b1 && !b2)

However, we can take advantage of the fact that the CC is already
negated, which lets us avoid special-casing PushNegate and doing
the simpler to reason about:

  (a || b)
  = !(!a && (!b))
  = !(!a && (b1 && b2))   <- changeFPCCToANDAArch64CC(!b, b1, b2)
  = !(!a && b1 && b2)

This makes both emitConditionalCompare cases behave identically,
and produces correct ccmp sequences for the 2-CC fcmps.

Change ConstantFoldInstOperands to take Instruction instead of opcode and type.  NFC.

Summary:
The previous form, taking opcode and type, is moved to an internal
helper and the new form, taking an instruction, is a wrapper around this
helper.

Although this is a slight cleanup on its own, the main motivation is to
refactor the constant folding API to ease migration to opaque pointers.
This will be follow-up work.

AMDGPU/SI: Pass whether to use the SI scheduler via Target Attribute

Summary:
Currently the SI scheduler can be selected via command line option,
but it turned out it would be better if it was selectable via a Target Attribute.

This patch adds "si-scheduler" attribute to the backend.
