This attribute controls optimizations which make assumptions about the
semantics of builtin functions. Typical cases here are code which
match memcpy, calloc, sincos, or which call builtins like free.
This extends on things like the -ftree-loop-distribute-patterns
flag. That flag only covers conve

Hi,
this patch is a small refactoring of ipa-modref to make it bit more
C++y by moving logic analyzing ssa name flags to a class
and I also moved the anonymous namespace markers so we do not
export unnecessary stuff. There are no functional changes.

These functions have been deprecated since C++11, and were removed in
C++17. The proposal P0323 wants to reuse the name std::unexpected for a
class template, so we will need to stop defining the current function
for C++23 anyway.
This marks them as deprecated for C++11 and up, to warn users they w
Recent fixes to avoid inappropriate folding of some conversions to
floating-point types with -frounding-math also prevented such folding
in C static initializers, when folding (in the default rounding mode,
exceptions discarded) is required for correctness.

This version of the patch specifically doesn’t deal with long double.
Mostly looking for Jonathan’s review to ensure his previous feedback is
addressed. I plan to rev the patch to handle long doubles after some
further discussion with you and Jonathan.
