David Goodwin de11f36ab7 Add aggressive anti-dependence breaker. Currently it is not the default for any target. Enable with -break-anti-dependencies=all.

Dan Gohman 6a1d9eace9 Check in the experimental GEP splitter pass. This pass splits complex 
GEPs (more than one non-zero index) into simple GEPs (at most one
non-zero index).  In some simple experiments using this it's not
uncommon to see 3% overall code size wins, because it exposes
redundancies that can be eliminated, however it's tricky to use
because instcombine aggressively undoes the work that this pass does.

Dan Gohman 9aba0d9988 When checking whether a def of an aliased register is dead, ask the 
machineinstr whether the aliased register is dead, rather than the original
register is dead. This allows it to get the correct answer when examining
an instruction like this:
  CALLpcrel32 <ga:foo>, %AL<imp-def>, %EAX<imp-def,dead>
where EAX is dead but a subregister of it is still live. This fixes PR5294.

Dan Gohman d632f89596 Make LSR's OptimizeShadowIV ignore induction variables with negative 
strides for now, because it doesn't handle them correctly. This fixes a
miscompile of SingleSource/Benchmarks/Misc-C++/ray.

This problem was usually hidden because indvars transforms such induction
variables into negations of canonical induction variables.

Zhongxing Xu b7945461cb 'error' is usually used as a noreturn function. This can suppress some false

Evan Cheng b81cb2a9a8 - Revert some changes from 85044, 85045, and 85047 that broke x86_64 tests and 
bootstrapping. It's not safe to leave identity subreg_to_reg and insert_subreg
  around.
- Relax register scavenging to allow use of partially "not-live" registers. It's
  common for targets to operate on registers where the top bits are undef. e.g.
  s0 =
  d0 = insert_subreg d0<undef>, s0, 1
  ...
     = d0
  When the insert_subreg is eliminated by the coalescer, the scavenger used to
  complain. The previous fix was to keep to insert_subreg around. But that's
  brittle and it's overly conservative when we want to use the scavenger to 
  allocate registers. It's actually legal and desirable for other instructions
  to use the "undef" part of d0. e.g.
  s0 =
  d0 = insert_subreg d0<undef>, s0, 1
  ...
  s1 =
     = s1
     = d0
  We probably need add a "partial-undef" marker on machine operand so the
  machine verifier would not complain.

Chris Lattner ecf328e6dd When parsing a top level struct declaration, make sure to 
process decl attributes instead of dropping them on the floor.
This allows us to diagnose cases like the testcase.  Also don't
diagnose deprecated stuff in ActOnTag: not all uses of tags
may be 'uses', and SemaType does this now.

 2009-10-25 22:21:57 +00:00
Chris Lattner e40853aabd move calls to DiagnoseUseOfDecl (which warns about deprecated/unavailable 
types) out of Sema::getTypeName into ConvertDeclSpecToType.  getTypeName
is sometimes used as a predicate in the parser, so it could cause redundant
diags to be emitted.  This is also needed by two upcoming enhancements.
