Mips built-in functions are currently not marked as pure, which
invalidates pointers across built-in function calls. If a pointer is
alive across built-in call, dereferencing it before and after the call
will generate two load instructions instead of one.
This marks the built-ins as pure, which re

This is a small fix for Bug 67299, where symbol: `Z1fCf` which would become
`f(float complex)` instead of `f(floatcomplex )`.
I thought this would be the preferred way of printing, because both
`llvm-cxxfilt` and `cpp_filt` both print the the mangled name in this
fashion.

Okay for trunk. For backports maybe wait a bit longer than usual? So ask
again in two weeks, maybe? I know it's important for the darwin port, but
the generic part is a little scary.

Hi!
objsz computation has two modes. One is a cheap one that doesn't handle
SSA_NAMEs and is used in say random builtin folding. The other is

Hi!
As written in the PR, location wrappers are stripped by
cxx_eval_constant_expression as the first thing it does after dealing with
jump_target. The problem is that when this function is called on a
CONSTRUCTOR, is TREE_CONSTANT and reduced_constant_expression_p (which
allows location wrappers

Hi,
this patch orders symbols where we copy sections to match the order
of files in the command line. This optimizes streaming process since we
are not opening and closing files randomly and also we read them more
sequentially. This saves some kernel time though I think more can be
done if we avo

The following bug has been introduced when cond_expr_object_size has been
added in 2007. We want to treat a COND_EXPR like a PHI with 2 arguments,
and PHI is handled in a loop that breaks if the lhs value is unknown, and
then does the if (TREE_CODE (arg) == SSA_NAME) merge_object_sizes else
