llvm-svn: 100657
 2010-04-07 18:20:42 +00:00
Anton Korobeynikov a3e4989ad8 Correct VMVN itinerary: operand is read in the second cycle, not in the first. 
llvm-svn: 100656
 2010-04-07 18:20:36 +00:00
Anton Korobeynikov 140a65ce0b More A9 itineraries

llvm-svn: 100654
 2010-04-07 18:20:24 +00:00
Anton Korobeynikov 4650fd5fc6 VP{MAX, MIN} are of IIC_VSUBi4D itin class as well. 
llvm-svn: 100653
 2010-04-07 18:20:18 +00:00
Anton Korobeynikov 7d4fad5942 VHADD differs from VHSUB at least on A9 - the former reads both operands in the second cycle, while the latter reads second operand in first cycle. Introduce new itin classes to catch this behavior. Whether this is true for A8 as well is WIP. 
llvm-svn: 100652
 2010-04-07 18:20:13 +00:00
Anton Korobeynikov 2cba05bbe1 Some easy NEON scheduling goodness for A9 
llvm-svn: 100651
 2010-04-07 18:20:07 +00:00
Anton Korobeynikov 2063705d91 Define new itin classes for ARM <-> VFP reg moves to distinguish from NEON ops. Define proper scheduling itinerary for them on A9. A8 TRM does not specify latency for them at all :( 
llvm-svn: 100650
 2010-04-07 18:20:02 +00:00
Anton Korobeynikov c1e7a6feac FCONST{S,D} behaves the same way as FP unary instructions. This is true for both A8 and A9. 
llvm-svn: 100649
 2010-04-07 18:19:56 +00:00
Anton Korobeynikov dad973334b Proper cycle times for locks, since wbck latency can be larger than fwd latency. 
llvm-svn: 100648
 2010-04-07 18:19:51 +00:00
Anton Korobeynikov 4c1da0f82a Add new itin classes for FP16 <-> FP32 conversions and make uise of them for A9. 
llvm-svn: 100647
 2010-04-07 18:19:46 +00:00
Anton Korobeynikov baeb210be7 Make use of new reserved/required scheduling stuff: introduce VFP and NEON locks to model domain cross stalls precisly. 
llvm-svn: 100646
 2010-04-07 18:19:40 +00:00
Anton Korobeynikov 0bdc6345e8 Initial support for different kinds of FU reservation. 
llvm-svn: 100645
 2010-04-07 18:19:32 +00:00
Anton Korobeynikov 9a348a9572 Factor out scoreboard into separate class. This way we might have several different score boards. 
llvm-svn: 100644
 2010-04-07 18:19:24 +00:00
Anton Korobeynikov 15ccae2a46 Some bits of A9 scheduling: VFP

llvm-svn: 100637
 2010-04-07 18:04:56 +00:00
Chris Lattner f839ee0c13 fix a latent bug my inline asm stuff exposed: 
MachineOperand::isIdenticalTo wasn't handling metadata operands.

Douglas Gregor 3b4abb6792 Improve handling of friend types in several ways: 
- When instantiating a friend type template, perform semantic
  analysis on the resulting type.
  - Downgrade the errors concerning friend type declarations that do
  not refer to classes to ExtWarns in C++98/03. C++0x allows
  practically any type to be befriended, and ignores the friend
  declaration if the type is not a class.

llvm-svn: 100635
 2010-04-07 17:57:12 +00:00
Douglas Gregor afb9bc10fa Split Sema::ActOnFriendTypeDecl into Sema::CheckFriendTypeDecl (for 
semantic analysis) and Sema::ActOnFriendTypeDecl (the action
callback). This is a prerequisite for improving template instantiation
of friend type declarations.

 2010-04-07 11:23:46 +00:00
Torok Edwin f8dba24a9b Workaround the breakage in r100616 by guarding all timers with 
TimePassesIsEnabled. This should allow make check to pass.

llvm-svn: 100618
 2010-04-07 10:44:46 +00:00
Bill Wendling fcc14141c7 Use the "NamedGroupTimer" class to categorize DWARF emission better. 
llvm-svn: 100616
 2010-04-07 09:28:04 +00:00
Benjamin Kramer 43c275fa56 Use raw_ostream. 
llvm-svn: 100615
 2010-04-07 09:26:51 +00:00
John McCall 8586bfd85d @llvm.sqrt isn't really close enough to C's sqrt to justify emitting calls 
to the intrinsic, even when math-errno is off.

Fixes rdar://problem/7828230 by falling back on the library function.
