Bug ID: 30162
Summary: Discrepancy in the interface exposed to tc_frob_label
Product: binutils
Version: unspecified
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: gas
Assignee: unassigned at sourceware dot org
Reporter: piannetta at kalrayinc dot com
Target Milestone: ---
After reading a label in gas/read.c, a CPU-specific back-end can register the
TC_FROB_LABEL hook. However, the position of the INPUT_LINE_POINTER is not the
same whether the label is surrounded by quotes or not:
- when the label is not surrounded by quotes, *INPUT_LINE_POINTER is the
character after the colon;
- when the label is surrounded by quotes, *INPUT_LINE_POINTER is the colon
itself.
I would expect that in both cases, *INPUT_LINE_POINTER is the character after
the colon. A simple fix would be to move the INPUT_LINE_POINTER once more when
the label symbol is terminated by a '"'.
