Bug ID: 93472
Summary: Document extended forms of constant expression
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: tromey at gcc dot gnu.org
Target Milestone: ---
GCC accepts extended forms of constant expression.
An example that came up recently was:
const int a = 5;
const int b = a;
IIUC the standard permits the compiler to accept other
forms of constant expression. However, I couldn't find
this in the documentation, and I think it would be
good if GCC documented the extensions it supports.
Perhaps a new node in the "C Implementation-Defined Behavior"
section would be appropriate.
