1/*
2 * Usage: dumpstab input-file
3 *
4 * There are two sources of information: the .stab/.stabstr
5 * sections of the executable and the COFF symbol table. Most
6 * of the information is in the .stab/.stabstr sections.
7 * However, most of our asm files don't contain .stab directives,
8 * so routines implemented in assembler won't show up in the
9 * .stab section. They are present in the COFF symbol table.
10 * So, we mostly use the .stab/.stabstr sections, but we augment
11 * the info there with info from the COFF symbol table when
12 * possible.
13 *
14 * This is a tool and is compiled using the host compiler,
15 * i.e. on Linux gcc and not mingw-gcc (cross-compiler).
16 * Therefore we can't include SDK headers and we have to
17 * duplicate some definitions here.
18 * Also note that the internal functions are "old C-style",
19 * returning an int, where a return of 0 means success and
20 * non-zero is failure.
