Chris Lattner 963b233f2c Work around a bug in the openbsd assembler on i386, 
which doesn't support .quad correctly because it is
"really really old".  PR6528.

Yet another reason the mc assembler should take over ;-)

Bill Wendling a810bdfcca Add a bit along with the MCSymbols stored in the MachineModuleInfo maps that 
indicates that an MCSymbol is external or not. (It's true if it's external.)
This will be used to specify the correct information to add to non-lazy
pointers. That will be explained further when this bit is used.

Anders Carlsson 0d0b588fb2 Get rid of the LayoutBaseNonVirtually; it was used to lay out a base either as a non-virtual base or a virtual base. 
llvm-svn: 98198

Anders Carlsson 09ffa32b92 More shuffling.

Dale Johannesen 49de0607a8 Progress towards shepherding debug info through SelectionDAG. 
No functional effect yet.  This is still evolving and should
not be viewed as final.

John McCall c9d4a84c2a Suppress the tag when printing an ElaboratedType if the language options 
claim this is C.  We don't make ElaboratedTypes in C, but sometimes
the language options during pretty-print lie to us.

The rewriter should really be fixed to not rely on how types are pretty-printed,
though.

Dan Gohman 703b12d62f Fix another bitwidth calculation to handle vector types; based on a

400.perlbench for the nightly tests.

Dan Gohman 2734ebd37f Add a DominatorTree argument to isLCSSA so that it doesn't have to 
compute a set of reachable blocks for itself each time it is called, which
is fairly frequently.

Johnny Chen 9a3e2398ae Factored out the disassembly printing of CPS option, MSR mask, and Negative Zero 
operands into their own PrintMethod, in order not to pollute the printOperand()
impl with disassembly only Imm modifiers.

Tobias Grosser ab19e1e9b5 Fix make check with cmake/lit 
PR6540: Set the newly introduced variables ENABLE_SHARED and
SHLIBPATH_VAR in lit.site.cfg not only in the autoconf build, but also
in a cmake one.

Richard Osborne 54a2c32670 Handle MVT::i64 type in DAG combine for ISD::ADD. Fold 64 bit 
expression add(add(mul(x,y),a),b) -> lmul(x,y,a,b) if all
operands are zero extended.

Bob Wilson dfebf1ffac Testcase for pr6552. I changed the code to use "ip" instead of "fp" because 
the "fp" register name is not valid on Darwin, and the "ip" register name was
broken for all ARM targets.

 2010-03-10 16:38:41 +00:00
Ted Kremenek ddce4a3d0f Really apply (unnoticed weird git-svn merge conflict in 98144): Refactor RegionStore::RemoveDeadBindings to use the same core cluster analysis algorithm as RegionStore::InvalidateRegions(). 
Beyond simplifying the algorithm significantly, we no longer
need to build subregion maps in RemoveDeadBindings().  This
and other changes cause a significant speedup: the time to
analyze sqlite3.c (single core) drops by 14%.
