PPCInstrVSX.td (they must be there, because the "vsrc" register class
definition appears there) for the VSRC register class.  The
SELECT_VSRC pseudo is then used in pattern matching for SELECT_CC.

logic appears for SELECT_VRRC.

[PECOFF] Fix exported symbol in the import library

There are two ways to specify a symbol to be exported in the module
definition file.

1) EXPORT <external name> = <symbol>
2) EXPORT <symbol>

In (1), you give both external name and internal name. In that case,
the linker tries to find a symbol using the internal name, and write
that address to the export table with the external name. Thus, from
the outer world, the symbol seems to be exported as the external name.

In (2), internal name is basically the same as the external name
with an exception: if you give an undecorated symbol to the EXPORT
directive, and if the linker finds a decorated symbol, the external
name for the symbol will become the decorated symbol.

Subclass InputGraph to get darwin linker library semantics

The darwin linker operates differently than the gnu linker with respect to
libraries. The darwin linker first links in all object files from the command
line, then to resolve any remaining undefines, it repeatedly iterates over
libraries on the command line until either all undefines are resolved or no
undefines were resolved in the last pass.

When Shankar made the InputGraph model, the plan for darwin was for the darwin
driver to place all libraries in a group at the end of the InputGraph. Thus
making the darwin model a subset of the gnu model. But it turns out that does
not work because the driver cannot tell if a file is an object or library until
it has been loaded, which happens later.

Teach combineMetadata how to merge 'nonnull' metadata.

combineMetadata is used when merging two instructions into one.  This change teaches it how to merge 'nonnull' - i.e. only preserve it on the new instruction if it's set on both sources.  This isn't actually used yet since I haven't adjusted any of the call sites to pass in nonnull as a 'known metadata'.

10 years agoPreserve 'nonnull' when changing type of the load.

Preserve 'nonnull' when changing type of the load.

When changing the type of a load in Chandler's recent InstCombine changes, we can preserve the new 'nonnull' metadata.

I considered adding an assert since 'nonnull' is only valid on pointer types, but casting a pointer to a non-pointer would involve more than a bitcast anyways.  If someone extends this transform to handle more than bitcasts, the verifier will report the malformed IR, so a separate assertion isn't needed.  Also, the fpmath flags would have the same problem.
