[Bug debug/18856] New: Missing .loc information after prologue

[tausq at debian dot org]

The attached program is extracted from the gdb testsuite (gdb.base/annota3.c)

According to Dan, the code generated by gcc is missing a .loc directive:
http://sources.redhat.com/ml/gdb-patches/2004-12/msg00143.html

i.e. gcc generates:

        .loc 1 6 0
handle_USR1:
        .PROC
        .CALLINFO FRAME=64,NO_CALLS,SAVE_SP,ENTRY_GR=3
        .ENTRY
        copy %r3,%r1
.LCFI0:
        copy %r30,%r3
.LCFI1:
        stwm %r1,64(%r30)
.LCFI2:
        stw %r26,-36(%r3)
        ldo 64(%r3),%r30
        ldwm -64(%r30),%r3
        bv,n %r0(%r2)
        .EXIT
        .PROCEND

but there should be another
        .loc 1 6 0
before the ldo insn.

gcc-3.4 handles this properly.
