Move library call prototype attribute inference to functionattrs2013-03-21T00:55:59ZMeador Ingemeadori@codesourcery.com2013-03-21T00:55:59Zurn:sha1:cf47ce616c53040cb8aa09eff9dc0b693e571842
The simplify-libcalls pass implemented a doInitialization hook to infer
function prototype attributes for well-known functions. Given that the
simplify-libcalls pass is going away *and* that the functionattrs pass
is already in place to deduce function attributes, I am moving this logic
to the functionattrs pass. This approach was discussed during patch
review:

Split out filename & directory from DIFile to start generalizing over DIScopes2013-03-17T21:13:55ZDavid Blaikiedblaikie@gmail.com2013-03-17T21:13:55Zurn:sha1:b4cf0ab22b5a3ebb720f0b7287fdccfb465b6b7c
This is the first step to making all DIScopes have a common metadata prefix (so
that things (using directives, for example) that can appear in any scope can be
added to that common prefix). DIFile is itself a DIScope so the common prefix
of all DIScopes cannot be a DIFile - instead it's the raw filename/directory
name pair.

Perform factorization as a last resort of unsafe fadd/fsub simplification.2013-03-14T18:08:26ZShuxin Yangshuxin.llvm@gmail.com2013-03-14T18:08:26Zurn:sha1:a0c9939873c404f272b3e0abb102c335146764fe
Rules include:
1)1 x*y +/- x*z => x*(y +/- z)
(the order of operands dosen't matter)
2) y/x +/- z/x => (y +/- z)/x
The transformation is disabled if the new add/sub expr "y +/- z" is a
denormal/naz/inifinity.

Remove the unused 4th operand for DIFile debug info metadata2013-03-13T22:05:21ZDavid Blaikiedblaikie@gmail.com2013-03-13T22:05:21Zurn:sha1:e0805a992ddd2823604969c8aac61a2f339f3c01

Refactor filename/directory in DICompileUnit into a DIFile2013-03-13T00:01:35ZDavid Blaikiedblaikie@gmail.com2013-03-13T00:01:35Zurn:sha1:de3077ae6b5ad8e6f417a8f6aa0ca1ae980f6272
This is the next step towards making the metadata for DIScopes have a common
prefix rather than having to delegate based on their tag type.

Upgrading debug info test cases to be (more) compatible with the current debug info format.2013-03-11T22:37:40ZDavid Blaikiedblaikie@gmail.com2013-03-11T22:37:40Zurn:sha1:850b74d3927c35850a99b10ca7809f61a3b69c67
These cases were found by further work to remove support for debug info
versioning. Common cleanups (other than changing the version info in the tag
field) included adding the last parameter to compile_units (recently added for
fission support) and other cases of trailing fields in lexical blocks, compile
units, and subprograms.

InstCombine: Don't shrink allocas when combining with a bitcast.2013-03-06T05:44:53ZJim Grosbachgrosbach@apple.com2013-03-06T05:44:53Zurn:sha1:186d8a3d67ccd2b2401c5d7d4e2cc15c4d1fdeae
When considering folding a bitcast of an alloca into the alloca itself,
make sure we don't shrink the amount of memory being allocated, or
things rapidly go sideways.

This adds minimalistic support for PHI nodes to llvm.objectsize() evaluation
fingers crossed so that it does break clang boostrap again..
