Bug ID: 89812
Summary: incorrect maximum in error: requested alignment
‘536870912’ exceeds maximum 2147483648
Product: gcc
Version: 9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: msebor at gcc dot gnu.org
Target Milestone: ---
The error below is justified but the value of the requested alignment (1 << 29,
or 536,870,912) does not exceed 2,147,483,648, or INT_MAX + 1U).
The maximum value looks like the result of a typo introduced in r265977
committed to fix bug 87795.
$ cat x.c && gcc -S x.c
typedef __attribute__ ((aligned (1U << 29))) char X;
x.c:1:1: error: requested alignment ‘536870912’ exceeds maximum 2147483648
1 | typedef __attribute__ ((aligned (1U << 29))) char X;
| ^~~~~~~
