Update to gcc6809lw patch which may help compilation of some sources
Due to persistent random compiler crashes and errors related to "M_REGS",
this patch update (4.6.4-2) essentially removes the varius constraints
allowing the "soft registers" in most operations. It was causing more
problems than it solved and it is not clear that the logic behind those soft
registers even makes sense any more.
This patch also fixes a bogus comparison related to selecting the right size
for a constant. Instead of the excessively clever comparison scheme that was
previously in use, the comparisons have been replaced with straight forward
comparisions for the top and bottom of the relevant 2's complement ranges.

Each line has the following structure: a zero-padded four-digit ASCII hex address, a colon separator, and one or more zero-padded two-digit hex values separated by commas. ASCII Hexadecimal format favors paragraph-aligned addresses (i.e. a least significant address nybble value of zero). During output, the number of hex values on each line are adjusted to align the address of the next line on a paragraph boundary. The sequence of addresses in the ASCII Hexadecimal file directly follows that of the source file; multiple ORG directives in the source code may result in out-of-sequence addresses in the ASCII Hexadecimal output.</P ><P >LWASM can output this format since version 4.10.</P ></DIV ><DIV CLASS="NAVFOOTER" ><HR ALIGN="LEFT" WIDTH="100%"><TABLE SUMMARY="Footer navigation table" WIDTH="100%" BORDER="0" CELLPADDING="0" CELLSPACING="0" ><TR ><TD WIDTH="33%" ALIGN="left" VALIGN="top" ><A HREF="x27.html" ACCESSKEY="P" >Prev</A ></TD ><TD WIDTH="34%" ALIGN="center" VALIGN="top" ><A HREF="index.html" ACCESSKEY="H" >Home</A ></TD ><TD WIDTH="33%" ALIGN="right" VALIGN="top" ><A HREF="x36.html" ACCESSKEY="N" >Next</A ></TD ></TR ><TR ><TD WIDTH="33%" ALIGN="left" VALIGN="top" >DECB Binaries</TD ><TD WIDTH="34%" ALIGN="center" VALIGN="top" ><A HREF="c21.html" ACCESSKEY="U" >Up</A ></TD ><TD WIDTH="33%" ALIGN="right" VALIGN="top" >Motorola S-Record</TD ></TR ></TABLE ></DIV ></BODY ></HTML >
