You can definitely make it ECF_LEAF too. I wonder if we can make it ECF_CONST

this would help to keep variadic functions const/pure that may be moderately

Hello,
I'm reviewing the original patch only for now.
The added bits in v2 will have to wait.

Dear All,
This patch exploits Mikael's identification of the location of the
problem and his testcase. It requires Andre's patch for PR59678 as a
prerequisite. It is almost certainly a bit over-conservative but it
seems to be free of any memory leakage. The ChangeLog and the comments
describe it s

Here is an updated version of the patch with, hopefully, all your
suggestions made. I decided to add calls to STRIP_NOPS before emitting
the warning so that we properly warn for cases where there's a cast in
between the whole thing, e.g.
if (!&(int &)a)
I also added guards to emit the warnings
handle_section_attribute contains many levels of nested conditionals and
branching code flow paths, with the error cases sometimes in the else
case and sometimes in the if case. Simplify the code flow into a series
of potential failure cases ending with the successful path, with no
nesting and no

Hi,
Here's another series to remove some conditional compilation.
each patch was bootstrapped and regtested on x86_64-linux-gnu, and the series
was run through config-list.mk. I think this all falls within Jeff's
preapproval so I'll commit it tomorrow (today actually) nig
