.SH DESCRIPTION
.PP
The command-line \f[V]umps3-elf2umps\f[R] utility is used to convert the
ELF formatted executable and object files produced by the gcc
cross-platform development tools into the \f[V].aout\f[R],
\f[V].core\f[R], and \f[V].rom\f[R] formatted files required by
\f[V]uMPS3\f[R].
.PP
A successful conversion will produce a file by the name of
\f[V]file.core.umps\f[R], \f[V]file.rom.umps\f[R], or
\f[V]file.aout.umps\f[R] accordingly.
.PP
A \f[V].stab\f[R] file is a text file containing a one-line
uMPS3-specific header and the contents of the symbol table from the
ELF-formatted input file.
It is used by the uMPS3 simulator to map \f[V].text\f[R] and
\f[V].data\f[R] locations to their symbolic, i.e.\ kernel/OS source
code, names.
Hence the automatic generation of the \f[V].stab\f[R] file whenever a
\f[V].core\f[R] file is produced.
Since \f[V].stab\f[R] files are text files one can also examine/modify
them using traditional text-processing tools.
.PP
In addition to its utility in tracking down errors in the
\f[V]umps3-elf2umps\f[R] program (which hopefully no longer exist), the
\f[I]-v\f[R] flag is of general interest since it illustrates which ELF
sections were found and produced and the resulting header data for
\f[V].core\f[R] and \f[V].aout\f[R] files.
For \f[V].rom\f[R] files, the \f[I]-v\f[R] flag also displays the BIOS
code size obtained during file conversion.
.SH OPTIONS
.TP
\f[V]-v\f[R]
Optional flag to produce verbose output during the conversion process.
.TP
\f[V]-m\f[R]
Optional flag to generate the \f[V].stab\f[R] symbol table map file
associated with \f[I]FILE\f[R].
.TP
\f[V]-k\f[R]
Flag to produce a \f[V].core\f[R] formatted file.
This flag can only be used with an executable file.
A \f[V].stab\f[R] file is automatically produced with this option.
.TP
\f[V]-b\f[R]
Flag to produce a \f[V].rom\f[R] formatted file.
This flag can only be used with an object file that does not contain
relocations.
.TP
\f[V]-a\f[R]
Flag to produce a \f[V].aout\f[R] formatted file.
