Bug ID: 113974
Summary: Attribute common ignored
Product: gcc
Version: 13.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: other
Assignee: unassigned at gcc dot gnu.org
Reporter: gjl at gcc dot gnu.org
Target Milestone: ---
__attribute__((common,used))
static int cc;
when this code is compiled with -S -fdata-sections then cc is not put into
.lcomm (and is not .local .comm either):
.section .bss.cc,"aw",@nobits
.align 4
.type cc, @object
.size cc, 4
cc:
.zero 4
.ident "GCC: (GNU) 13.2.1 20231022"
with -fno-data-sections, though, it works as expected:
.local cc
.comm cc,4,4
