Bug ID: 31284
Summary: scfi: untraceable control flow should be a hard error
Product: binutils
Version: 2.43 (HEAD)
Status: NEW
Severity: normal
Priority: P2
Component: gas
Assignee: unassigned at sourceware dot org
Reporter: indu.bhagat at oracle dot com
Target Milestone: ---
Currently, if an indirect jump is seen, GCFG (a CFG of ginsns) cannot be
created. GCFG creation is necessary for SCFI (invoked via --scfi=experimental
on hand-written asm) passes. In this case, the SCFI machinery currently bails
out with a warning:
"Untraceable control flow for func 'foo'; Skipping SCFI"
It is, however, better suited if this is a hard error. Change it to a hard
error.
