[Bug tdep/20406] New: Missing `alloca' handler in the microMIPS heuristic prologue scanner


https://sourceware.org/bugzilla/show_bug.cgi?id=20406

            Bug ID: 20406
           Summary: Missing `alloca' handler in the microMIPS heuristic
                    prologue scanner
           Product: gdb
           Version: HEAD
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: P2
         Component: tdep
          Assignee: unassigned at sourceware dot org
          Reporter: macro@linux-mips.org
  Target Milestone: ---
            Target: mips*-*-*

It has been revealed by commit c097ec493b76 ("Remove unused variables")
that the microMIPS heuristic prologue scanner (`micromips_scan_prologue')
is missing `alloca' handling corresponding to code in the regular MIPS
scanner (`mips32_scan_prologue').  It would be good to have it
implemented sometime.
