Messages sorted by: [ date ] [ thread ] [ subject ] [ author ]

Use the newly added SYM_FUNC_START_LOCAL to annotate starts of all
functions which do not have ".globl" annotation, but their ends are
annotated by ENDPROC. This is needed to balance ENDPROC for tools that
are about to generate debuginfo.
