2010-02-15Uniformize the names of type predicates: rather than having isFloatTy andDuncan Sands
isInteger, we now have isFloatTy and isIntegerTy. Requested by Chris! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96223 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-15When testing whether a given SCEV depends on a temporary symbolicDan Gohman
name, test whether the SCEV itself is that temporary symbolic name, in addition to checking whether the symbolic name appears as a possibly-indirect operand. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96216 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-15Check in the first big step of rewriting DAGISelEmitter to Chris Lattner
produce a table based matcher instead of gobs of C++ Code. Though it's not done yet, the shrinkage seems promising, the table for the X86 ISel is 75K and still has a lot of optimization to come (compare to the ~1.5M of .o generated the old way, much of which will go away). The code is currently disabled by default (the #if 0 in DAGISelEmitter.cpp). When enabled it generates a dead SelectCode2 function in the DAGISel Header which will eventually replace SelectCode. There is still a lot of stuff left to do, which are documented with a trail of FIXMEs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96215 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-15Revert r96130 ("Forward parameter options as '-option=param'").Mikhail Glushenkov
This behaviour must be configurable. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96210 91177308-0d34-0410-b5e6-96231b3b80d8

which may call write_impl on things that are not the usual buffer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96209 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-15When restoring a saved insert location, check to see if the savedDan Gohman
insert location has become an "inserted" instruction since the time it was saved. If so, advance to the first non-"inserted" instruction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96203 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-14remove the DisablePatternForFastISel predicate, which is a checkChris Lattner
that predated -fast-isel which attempted to speed up the dag pattern matchers at -O0. Since fast-isel is around, this is basically obsolete and removing it shrinks the generated dag isels. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96188 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96178 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-14When complicated expressions are broken down into subexpressionsDan Gohman
with multiplication by constants distributed through, occasionally those subexpressions can include both x and -x. For now, if this condition is discovered within LSR, just prune such cases away, as they won't be profitable. This fixes a "zero allocated in a base register" assertion failure. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96177 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-14Drop winmcasminfo and use normal AT&T COFF for all windows targets.Anton Korobeynikov
Otherwise AT&T asm printer is used with non-compatible MCAsmInfo and there is no way to override this behaviour. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96165 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-14Try to factorize the specification of saturating add/subtract operations a bit,Johnny Chen
as suggested by Bob Wilson. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96153 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-14Actually, this code doesn't have to be quite so conservative inDan Gohman
the no-TLI case. But it should still default to declining the transformation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96152 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-14In rememberInstruction, if the value being remembered is theDan Gohman
current insertion point, advance the current insertion point. This avoids a use-before-def situation in a testcase extracted from clang which is difficult to reduce to a reasonable-sized regression test. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96151 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-14Simplify this code; no need for a custom subclass if it doesn't needDan Gohman
to override anything from the parent class. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96150 91177308-0d34-0410-b5e6-96231b3b80d8
