Chris Lattner 1a8b80ed5a teach ipsccp and ipconstprop that a blockaddress doesn't 'take the address' of a function
in a way that should prevent ip constprop.  This allows clang/test/CodeGen/indirect-goto.c
to pass with the new indirect goto lowering.

llvm-svn: 85709
2009-11-01 06:11:53 +00:00
Chris Lattner ee8b951e73 teach various passes about blockaddress. We no longer
crash on any clang tests.

Victor Hernandez 762195bd01 Rename MallocHelper as MallocFreeHelper, since it now also identifies calls to free()

Victor Hernandez de5ad42aa1 Remove FreeInst.
Remove LowerAllocations pass.
Update some more passes to treate free calls just like they were treating FreeInst.

2009-10-26 23:43:48 +00:00
Victor Hernandez e297149e26 Auto-upgrade free instructions to calls to the builtin free function.
Update all analysis passes and transforms to treat free calls just like FreeInst.
Remove RaiseAllocations and all its tests since FreeInst no longer needs to be raised.

2009-10-24 04:23:03 +00:00
Victor Hernandez 8acf2956b8 Remove AllocationInst. Since MallocInst went away, AllocaInst is the only subclass of AllocationInst, so it no longer is necessary.

Torok Edwin 729d92bd74 Fix PR4313: IPSCCP was not setting the lattice value for the invoke instruction
when the invoke had multiple return values: it set the lattice value only on the
extractvalue.
This caused the invoke's lattice value to remain the default (undefined), and
later propagated to extractvalue's operand, which incorrectly introduces
undefined behavior.

Dan Gohman e525d9ddc0 Remove an unnnecessary LLVMContext argument in
ConstantFoldLoadThroughGEPConstantExpr.

Chris Lattner fdd8790718 strength reduce a ton of type equality tests to check the typeid (Through
the new predicates I added) instead of going through a context and doing a
pointer comparison.  Besides being cheaper, this allows a smart compiler
to turn the if sequence into a switch.

Chris Lattner f9e0c7f84b calls to external functions are already marked overdefined, special casing
malloc isn't needed.

Torok Edwin 21bd8c9fc5 Constant propagating byval pointer is safe if function is readonly.
llvm-svn: 82700
2009-09-24 18:33:42 +00:00
Torok Edwin f95a450ef9 Don't constant propagate byval pointers, since they are not really pointers, but
rather structs passed by value.
This fixes PR5038.

Victor Hernandez 5d034499ad Enhance transform passes so that they apply the same tranforms to malloc calls as to MallocInst.

Chris Lattner b25de3ff60 eliminate the "Value" printing methods that print to a std::ostream.
This required converting a bunch of stuff off DOUT and other cleanups.

Dan Gohman 8dd69f88ea Fix debug output to include a newline after printing a Value, now

Owen Anderson 5a1acd9912 Move a few more APIs back to 2.5 forms. The only remaining ones left to change back are
metadata related, which I'm waiting on to avoid conflicting with Devang.

Daniel Dunbar 0dd5e1ed39 More migration to raw_ostream, the water has dried up around the iostream hole.
- Some clients which used DOUT have moved to DEBUG. We are deprecating the
   "magic" DOUT behavior which avoided calling printing functions when the
   statement was disabled. In addition to being unnecessary magic, it had the
   downside of leaving code in -Asserts builds, and of hiding potentially
   unnecessary computations.

our current context-passing stuff, which is also fixed here

Torok Edwin fbcc663cbf llvm_unreachable->llvm_unreachable(0), LLVM_UNREACHABLE->llvm_unreachable.
This adds location info for all llvm_unreachable calls (which is a macro now) in
!NDEBUG builds.
In NDEBUG builds location info and the message is off (it only prints
"UREACHABLE executed").

Torok Edwin 56d0659726 assert(0) -> LLVM_UNREACHABLE.
Make llvm_unreachable take an optional string, thus moving the cerr<< out of
line.
LLVM_UNREACHABLE is now a simple wrapper that makes the message go away for
NDEBUG builds.
