causing assertion failures in getSExtValue().
Fix it by making highWordBits actually contain what its name says,
and add some more unit-tests for APInt.
This fixes PR3419.

DW_AT_APPLE_optimized flag is set when a compile_unit is optimized. The debugger takes advantage of this information some way.

DW_AT_APPLE_flags encodes command line options when certain env. variable is set. This is used by build engineers to track various gcc command lines used by by  a project, irrespective of whether the project used makefile, Xcode or something else.

llvm-gcc patch is next.

ASCII IR; loading and storing these can change the
bits of NaNs on some hosts.  Remove or add warnings
at a few other places using host floating point;
this is a bad thing to do in general.

Besides APFloat, this involved removing code
from two places that thought they knew the
result of frem(0., x) but were wrong.

mainly to clarify that APFloat::mod implements

Add 'tell' method to raw_fd_ostream that clients can use to query the current location in the file the stream is writing to.

Revert r60042. IndVarSimplify should check if APFloat is PPCDoubleDouble first before trying to convert it to an integer.

llvm-svn: 60072

change AnnotationManager to use 'const char*' instead of std::string. this fixes the leakage of those strings and avoids the creation of such strings in static cosntructors (should result in a little improvement of startup time)

llvm-svn: 60064

convertToSignExtendedInteger should return opInvalidOp instead of asserting if sematics of float does not allow arithmetics.

two spaces. This makes these strings less mysterious, and it fixes
some cases where short description strings mistakenly did not
begin with two spaces.

This prevents llvm from reducing -0.0 to a
