The r12-3346 patch makes us avoid computing excess argument conversions
during overload resolution, but only when it turns out there's a
strictly viable candidate in the overload set. If there is no such
candidate then we still need to compute more conversions than strictly
necessary because subse

Dear all,
in find_substring_ref we erroneously handled given substring start and end
indices as unsigned integers. However, gives indices could be negative,
which is legal as long as end < start, leading to a string of length zero.
The current behavior could lead to a wrong length as well as an i

Hi!
While mass-building a cross-gcc, I noticed that for
alpha-dec-vms/alpha64-dec-vms, recent GCC versions correctly throw a warning
due to a multi-statement define that gets rippen in an if/else case:

Hi Kewen,
I'll leave the continued review of the back-end parts of this to Segher,
but I do have one long-term comment. The rs6000_builtin_info[code].mask
field that you're relying on is going away as part of the built-in
function rewrite. There will be a "bifattrs" field that replaces this

So right now liblto_plugin.so exports many libiberty symbols and
simple_object file symbols but really it just needs to export onload.
This fixes the problem by using "-export-symbols-regex onload" on
the libtool link line.

Hi,
This patch fixes an issue with the routine that converts STRING_CST to a
StringExp for the dmd front-end to use during the semantic pass.
The null terminator gets re-added by the ExprVisitor when lowering
StringExp back into a STRING_CST during the code generator pass.

Hi Peter,
This patch looks fine to me. The approach to avoiding incorrect
optimization is reasonable. Maintainers?
Thanks for the patch!
