20 years agoStart implementing DSGraph::clonePartiallyInto and implement mergeInGraph
Chris Lattner [Thu, 22 Jan 2004 15:30:58 +0000 (15:30 +0000)]
Start implementing DSGraph::clonePartiallyInto and implement mergeInGraph
in terms of it.

Though clonePartiallyInto is not cloning partial graphs yet, this change
dramatically speeds up inlining of graphs with many scalars.  For example,
this change speeds up the BU pass on 253.perlbmk from 69s to 36s, because
it avoids iteration over the scalar map, which can get pretty large.

Eliminate the isStringCompatible function, using ConstantArray::isString.
It's not clear why the code was looking for signed chars < 0, but it can't
matter to the assembler anyway, so the check goes away.  This also fixes
compatibility with arrays of [us]byte that have constantexprs in them.

Also slightly restructure some code to be cleaner.
