Michael J. Spencer 4d0c6fdda6 unittests/Support/PathV2: Make tests much shorter; although harder to understand. 
I'm going to replace this all anyway with a proper table and separated tests
when done.

apparently it is unused.

Dan Gohman e41b1463f9 Delete Path::appendSuffix's return value; it wasn't used anywhere, which 
is fine since isn't really necessary to check isValid there anyway.

Chris Lattner 1c577b54b0 fix a bozo bug I introduced in r119930, causing a miscompile of 
20040709-1.c from the gcc testsuite.  I was using the size of a
pointer instead of the pointee.  This fixes rdar://8713376

Evan Cheng d4b0873c06 Enable sibling call optimization of libcalls which are expanded during 
legalization time. Since at legalization time there is no mapping from
SDNode back to the corresponding LLVM instruction and the return
SDNode is target specific, this requires a target hook to check for
eligibility. Only x86 and ARM support this form of sibcall optimization
right now.

Andrew Trick fce64c938a Coding style. No significant functionality. Abandon linear scan style 
in favor of the widespread llvm style. Capitalize variables and add
newlines for visual parsing. Rename variables for readability.

Chris Lattner c0f3379ae0 teach DSE to use GetPointerBaseWithConstantOffset to analyze 
may-aliasing stores that partially overlap with different base
pointers.  This implements PR6043 and the non-variable part of
PR8657

Bill Wendling a9e3df7aa0 * Add support for encoding t_addrmode_s2 and t_addrmode_s1. They are the same as 
t_addrmode_s4, but with a different scaling factor.

* Encode the Thumb1 load and store instructions. This involved a bit of
  refactoring (hi, Chris! :-). Some of the patterns became dead afterwards and
  were removed.

 2010-11-30 22:57:21 +00:00
Owen Anderson 8335e8fa63 Simplify the encoding of reg+/-imm12 values that allow PC-relative encoding. This allows the 
Thumb2 encoding to share code with the ARM encoding, which gets use fixup support for free.
It also allows us to fold away at least one codegen-only pattern.

llvm-svn: 120481

Chris Lattner 51d67ce2ff switch RemoveAccessedObjects to use AliasAnalysis::Location to simplify 
the code.  We now get accurate sizes on Loads, though it surely doesn't
matter in practice.

llvm-svn: 120469
 2010-11-30 21:47:58 +00:00
Chris Lattner f80b39986f two improvements to RemoveAccessedObjects: 
1. if the underlying pointer passed in can be resolved
   to any argument or alloca, then we don't need to scan.
   Previously we would only avoid the scan if the alloca
   or byval was actually considered dead.
2. The dead store processing code is itself completely
   dead and didn't handle volatile stores right anyway,
   so delete it.  This allows simplifying the interface
   to RemoveAccessedObjects.
