Nick Lewycky 4d0ed842b1 Prune the unwind_to labels on BBs that don't need them. Another step in the 
removal of invoke, PR1269.

Dale Johannesen 09f410b6d7 Split ParameterAttributes.h, putting the complicated 
stuff into ParamAttrsList.h.  Per feedback from
ParamAttrs changes.

Dale Johannesen 89268bc6e2 Expand ParameterAttributes to 32 bits (in preparation 
for adding alignment info, not there yet).  Clean up
interfaces to reference ParameterAttributes consistently.

Duncan Sands aa31b92508 When inlining through an 'nounwind' call, mark inlined 
calls 'nounwind'.  It is important for correct C++
exception handling that nounwind markings do not get
lost, so this transformation is actually needed for
correctness.

Duncan Sands 3353ed09ac Rename isNoReturn to doesNotReturn, and isNoUnwind to 
doesNotThrow.

Duncan Sands 9f76be61d1 Make PruneEH update the nounwind/noreturn attributes 
on functions as it calculates them.

Duncan Sands ad0ea2d430 Fix PR1146: parameter attributes are longer part of 
the function type, instead they belong to functions
and function calls.  This is an updated and slightly
corrected version of Reid Spencer's original patch.
The only known problem is that auto-upgrading of
bitcode files doesn't seem to work properly (see
test/Bitcode/AutoUpgradeIntrinsics.ll).  Hopefully
a bitcode guru (who might that be? :) ) will fix it.

David Greene 17a5dfe6f7 New CallInst interface to address GLIBCXX_DEBUG errors caused by

Devang Patel 8c78a0bff0 Drop 'const' 
llvm-svn: 36662
 2007-05-03 01:11:54 +00:00
Devang Patel e95c6ad802 Use 'static const char' instead of 'static const int'. 
Due to darwin gcc bug, one version of darwin linker coalesces
static const int, which defauts PassID based pass identification.

Reid Spencer 557ab15e71 Apply the VISIBILITY_HIDDEN field to the remaining anonymous classes in 
the Transforms library. This reduces debug library size by 132 KB, debug
binary size by 376 KB, and reduces link time for llvm tools slightly.

Chris Lattner 93f4e9dd26 detect functions that never return, and turn the instruction following a 
call to them into an 'unreachable' instruction.

Chris Lattner 4f2cf030e8 'Pass' should now not be derived from by clients. Instead, they should derive 
from ModulePass.  Instead of implementing Pass::run, then should implement
ModulePass::runOnModule.
