Bug ID: 21762
Summary: Use of STABS directives on MIPS causes label to be
incorrectly marked as MIPS16
Product: binutils
Version: 2.28
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: gas
Assignee: unassigned at sourceware dot org
Reporter: james410 at cowgill dot org.uk
Target Milestone: ---
On MIPS, attempting to use a STABS directive (.stabs, .stabn or .stabd) before
a .set directive has occured in the input file, causes any preceding labels to
be marked as MIPS16.
> $ cat test.s
> main:
> .stabd 0, 0, 0
> $ mips-linux-gnu-as test.s -o test.o
> $ readelf --syms test.o | grep main
> 4: 00000000 0 NOTYPE LOCAL DEFAULT [MIPS16] 1 main
Passing -no-mips16 causes as to emit a micromips symbol instead:
> $ mips-linux-gnu-as -no-mips16 test.s -o test.o
> $ readelf --syms test.o | grep main
> 4: 00000000 0 NOTYPE LOCAL DEFAULT [MICROMIPS] 1 main
Using some noop .set directive before the .stabd works around the bug:
> $ cat test.s
> main:
> .set mips0
> .stabd 0, 0, 0
> $ mips-linux-gnu-as test.s -o test.o
> $ readelf --syms test.o | grep main
> 4: 00000000 0 NOTYPE LOCAL DEFAULT 1 main
