Chris Lattner 1f49988a7a This is a simple fix for getting error messages from dlerror in 
LoadLibraryPermanently. The current code modifies the value of a pointer
that is passed by value, so the caller never gets the message.

Patch by Julien Lerouge!

 2008-03-12 00:32:32 +00:00
Steve Naroff dc5b6b2e5d Make ivar rewrite C++ friendly (since C++ forces a unified namespace for typedefs/structures). The previous version of the rewriter generated both a type def and structure def for each class (which doesn't fly in C++).

Dan Gohman 35f8f07c00 Make this test x86-specific for now; targets that don't use 
the automated CallingConv code to handle return values typically
don't support multiple return values.

Dan Gohman 24570836b2 Use PassManagerBase instead of FunctionPassManager for functions 
that merely add passes. This allows them to be used with either
FunctionPassManager or PassManager, or even with a custom new
kind of pass manager.

Dan Gohman 20af5a0fe7 Check to see if a two-entry PHI block can be simplified 
before trying to merge the block into its predecessors.
This allows two-entry-phi-return.ll to be simplified
into a single basic block.

Dan Gohman 8e9ae96a4a Make this test more challenging to help it avoid being

Chris Lattner 8abed80a69 Implement basic support for the 'f' register class constraint. This basically 
works, but probably won't if you mix it with 't' or 'u' yet.

llvm-svn: 48227
 2008-03-11 17:32:05 +00:00
Dan Gohman d3a20c9e1e Give PassManager and FunctionPassManager a common base class, with 
add(Pass *) as a pure virtual member function. This will allow all
the various addPassesTo* functions in LLVM to avoid hard-coding what
type of PassManager is used.
