Hi,
Currently, format attribute can be used to do type-checking for arguments
with respect to a format string. However, only functions with a C-style
ellipsis can use it.
Supporting this attribute for non-variadic functions(functions without a
C-style ellipsis) gives nice convenience especially w

To improve phiopt and be able to remove abs_replacement, this ports
most of "A CMP 0 ? A : -A" from fold_cond_expr_with_comparison to
match.pd. There is a few extra changes that are needed to remove
the "A CMP 0 ? A : -A" part from fold_cond_expr_with_comparison:

From: Andrew Pinski
Since match and simplify does not have all of the inverted
comparison patterns, it make sense to just have
phi-opt try to do the inversion and try match and simplify again.
OK? Bootstrapped and tested on x86_64-linux-gnu.
Thanks,

To move a few things more to match-and-simplify from phiopt,
we need to allow match_simplify_replacement to run in early
phiopt. To do this we add a replacement for gimple_simplify
that is explictly for phiopt.
OK? Bootstrapped and tested on x86_64-linux-gnu with no

From: Andrew Pinski
Since match_simplify_replacement uses gimple_simplify, there is a new
ssa name created sometimes and then we go and replace the phi edge with
this new ssa name, the range information on the phi is lost.
Placing this in replace_phi_edge_with_variable is the best option instead
From: Andrew Pinski
To able to move PHI-OPT's abs_replacement to match.pd, a bunch
of support needed to be added to PHI-OPT.
This is a set of 4 (unapproved) patches which allows us to remove
abs_replacement and even does one set further and does a few extra
transformations that abs_replacement di

This fixes PR 101230 where I had messed up and forgot that
invert_tree_comparison can return ERROR_MARK if the comparsion
is not invertable (floating point types).
