$! If you are using a version of GCC that supports global constants
|
||
|
|
$! you should remove the define="const=" from the gcc lines.
|
||
|
|
$!
|
||
|
|
$! Caution: Versions 1.38.1 and earlier had a bug in the handling of
|
||
|
|
$! some static constants. If you are using such a version of the
|
||
|
|
$! assembler, and you wish to compile without the "const=" hack,
|
||
|
|
$! you should first build this version *with* the "const="
|
||
|
|
$! definition, and then use that assembler to rebuild it without the
|
||
|
|
$! "const=" definition. Failure to do this will result in an assembler
|
||
|
|
$! that will mung floating point constants.
|
||
|
|
$!
|
||
|
|
$! Note: The version of gas shipped on the GCC VMS tapes has been patched
|
||
|
|
$! to fix the above mentioned bug.
