Chris Lattner fb95472123 When we restore signal handlers, restore them back to what they 
were when we came around, not to their default handler.  This 
should fix PR3848

Chris Lattner 30bc972596 VC++ 6.0 is not future work :) 
Do not recommend llvm::OStream anymore.  Use raw_ostream or MemoryBuffer.

work.

Bill Wendling a443ab4bcd Really should pass -dylib to the linker... 
llvm-svn: 67469
 2009-03-22 08:56:15 +00:00
Bill Wendling f3ef2c758f A dylib should be built as a dylib and not a bundle.

llvm-svn: 67451
 2009-03-21 18:12:24 +00:00
Chris Lattner cbeda87da1 add a fastpath to ConstantExpr::getBitCast to handle the case when an obviously 
unneeded bitcast is requested.  This is common for frontends who just unconditionally
cast even if the target is often the right type already.  THis prevents going into
getFoldedCast which switches on the opcode and does a bunch of other stuff before
doing the same opzn.

Chris Lattner 0a981d1d36 Fix instcombine to not introduce undefined shifts when merging two 
shifts together.  This fixes PR3851.

 2009-03-20 22:41:15 +00:00
Duncan Sands a09e0afe74 Don't load values out of global constants with weak 
linkage: the value may be replaced with something
different at link time.  (Frontends that want to
allow values to be loaded out of weak constants can
give their constants weak_odr linkage).

Dan Gohman 3bdc4bdba6 Simplify this code; use a while instead of an if and a do-while.

Mon P Wang f67448adf8 Added option to enable generating less precise mad (multiply addition) 
for those architectures that support the instruction.

Dan Gohman 76402b9a3d The last use in a block that doesn't have successors 
(return or unreachable) is a kill.

 2009-03-20 00:14:09 +00:00
Sebastian Redl 8d5baa09f8 Fix the Win32 VS2008 build: 
- Make type declarations match the struct/class keyword of the definition.
 - Move AddSignalHandler into the namespace where it belongs.
 - Correctly call functions from template base.
 - Some other small changes.
With this patch, LLVM and Clang should build properly and with far less noise under VS2008.

Evan Cheng 1361cbbb0b Added MachineInstr::isRegTiedToDefOperand to check for two-addressness.

Evan Cheng 05799db963 More makefile changes to allow dejagnu tests to pass when system tools default to a different target from the llvm configuration (e.g. 64-bit gcc and 32-bit llvm). 
llvm-svn: 67334

Misha Brukman 5182b758a0 Renamed unittest files to have a consistent {Tt}est suffix.

Dan Gohman 1026a8001f SADDO and UADDO are commutative.

Dale Johannesen 2050968df9 Clear the cached cost when removing a function in 
the inliner; prevents nondeterministic behavior
when the same address is reallocated.
Don't build call graph nodes for debug intrinsic calls;
they're useless, and there were typically a lot of them.

llvm-svn: 67311
 2009-03-19 18:03:56 +00:00
Dan Gohman 37061eef5d Add a liveness analysis pass for LLVM IR values. This computes 
the set of blocks in which values are used, the set in which
values are live-through, and the set in which values are
killed. For the live-through and killed sets, conservative
approximations are used.

llvm-svn: 67309

Dale Johannesen e4f361212b Fix comment typo. 
llvm-svn: 67307
 2009-03-19 17:23:29 +00:00
Dale Johannesen 52bc2aac8a This pass keeps a map of Instructions to Rank numbers, 
and was deleting Instructions without clearing the
corresponding map entry.  This led to nondeterministic
behavior if the same address got allocated to another
Instruction within a short time.

Ted Kremenek dd03b5bb63 Fix regression in 'tblgen -gen-clang-diags-defs': Emit the diagnostic kind instead of "DIAGNOSTICCONTROLLED". 
llvm-svn: 67305

Chris Lattner 58bd3dccf9 Fix PEI to not walk off the start of a block when an updated instruction 
is the first in its block.  This is PR3842.

llvm-svn: 67304

either.

 2009-03-19 05:51:39 +00:00
Nate Begeman dbe3f77f5b Add support to tablegen for naming the nodes themselves, not just the operands, 
in selectiondag patterns.  This is required for the upcoming shuffle_vector rewrite,
and as it turns out, cleans up a hack in the Alpha instruction info.
