Bug ID: 58218
Summary: -mcmodel=medium cause assembler warning "ignoring
incorrect section type for .lbss"
Product: gcc
Version: 4.8.1
Status: UNCONFIRMED
Severity: minor
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: zeccav at gmail dot com
The following statement causes an assembler warning from gcc when compiled with
-mcmodel=medium
Any other -mcmodel suboptions work fine.
This is the culprit:
struct { float x[16385]; } a = { { 0.f, } };
This bug was found by Mat Cross of NAG.

--- Comment #1 from Mikael Pettersson <mikpe at it dot uu.se> ---
I can reproduce with gcc-4.7.3. It generates:
.section .lbss,"aw",@progbits
gas doesn't like ,@progbits on .lbss and ignores it; readelf on the produced .o
file then shows:
[ 4] .lbss NOBITS 0000000000000000 000040 010004 00 WAl
0 0 32
which appears to confirm that @progbits is wrong. (.bss is also NOBITS.)
