I do see make using ‘GDC' while building gcc compiler, maybe try changing that ?

Is there an environment variable like 'CC' or 'CXX', which specifies the name
of the D compiler to use, which I might need to set when bootstrapping GCC?
Thanks.

Yes, it causes the bmi to be saved. In fact, when we add `-save-temps` option
in clang and we compile a module unit, we'll see the preprocessed output, the

The Clang doc acually show all the forms that can be used for each attribute:

Ah got it, didn't know that (handy, will save me duplicating a bunch of
attributes).

Oh, D'oh! Thanks Joseph, apologies for the needless email on the list then.
One final question if I could -- does that mean that in order to support
"may-alias" with the bracket syntax on both Clang and GCC, it would require:
union [[gnu::may_alias]] [[clang::may_alias]] foo {};

With [[]] syntax it's [[gnu::may_alias]], since it's not a standard
attribute.

Hi!
In the following function, past_end is a pointer to one-past-the-end of the
array. Holding such a pointer is legal in C. I use it as a sentinel value that
helps (1) avoid overrunning the buffer, and (2) detect truncation. I mark it as
having a size of [0], which clearly states that it c

Greetings, David, community,
I'd like to get your input on how GCC command line interface should support
making a "tiered" warning like -Warray-bounds={1,2} an error for "tier 1"
where fewer false positives are expected, and a plain warning otherwise.
There was a recent thread mentioning the curr
