Duncan Sands 68b6f50938 Integrate the readonly/readnone logic more deeply
into alias analysis.  This meant updating the API
which now has versions of the getModRefBehavior,
doesNotAccessMemory and onlyReadsMemory methods
which take a callsite parameter.  These should be
used unless the callsite is not known, since in
general they can do a better job than the versions
that take a function.  Also, users should no longer
call the version of getModRefBehavior that takes
both a function and a callsite.  To reduce the
chance of misuse it is now protected.

Duncan Sands 1c97d752df Readonly/readnone functions are allowed to throw
exceptions, so don't turn invokes of them into
calls.

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 79a42ac941 Switch over Transforms/Scalar to use the STATISTIC macro. For each statistic
converted, we lose a static initializer.  This also allows GCC to emit warnings
about unused statistics.

Chris Lattner 700b873130 Detemplatize the Statistic class. The only type it is instantiated with

Chris Lattner 6a792feb02 Getting ADCE to interact well with unreachable instructions seems like a nontrivial
exercise that I'm not interested in tackling right now.  Just punt and treat them
like unwind's.
