Explicit node for static symbol (addresses). Should not break with edge
cases like the previous ad-hoc approach. And some other bugfixes
c: relax constexpr constraints, fix alignof2026-03-09T09:24:39+00:00lemonlsof@mailbox.org2026-03-09T09:24:39+00:00urn:sha1:1529b5221389c75371d0f3f181957a77a158a53c
- Allow short-circuiting of constant logical expressions where the
unevaluated operand is not a constant expression (`1 || 0/0`)
- Allow constant integer expressions that evaluate to zero to be used
as null pointer constants (GNU extension).
+ According to the standard, `int *x = 5*0;` should be rejected.
But compilers evaluate `5*0 -> 0` and allow it as if a null pointer
literal.
c: recognize another static initializer edge case2026-03-05T18:22:08+00:00lemonlsof@mailbox.org2026-03-05T18:22:08+00:00urn:sha1:25a143d75df857c6b76c67a71a3683d0191c711b
I think globsym & expr2reloc should be rewritten to be more robust to
this kind of thing. Accumulate offsets whilst recursing into the child
node that might contain a direct global symbol reference kind of thing.
