Bug ID: 25275
Summary: Dollar labels do not work
Product: binutils
Version: 2.34 (HEAD)
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: gas
Assignee: unassigned at sourceware dot org
Reporter: sergey.belyashov at gmail dot com
Target Milestone: ---
Note: Dollar label is true temporary label which lives between two normal label
definition.
I trying to compile next Z80 code (z80-unknown-coff, target is not sufficient,
but DOLLAR_LOCAL_LABELS should be defined as 1 in target sources: tc-*.h and/or
te-*.h):

Compiler does not known dollar-labels defined before use. Is it OK?
Moreover, I try to find any test for dollar-label usage, but it not present. So
this feature exists in sources but not tested anythere!
