10 $! Command file to build a GNU assembler on VMS
12 $! If you are using a version of GCC that supports global constants
13 $! you should remove the define="const=" from the gcc lines.
15 $! Caution: Versions 1.38.1 and earlier had a bug in the handling of
16 $! some static constants. If you are using such a version of the
17 $! assembler, and you wish to compile without the "const=" hack,
18 $! you should first build this version *with* the "const="
19 $! definition, and then use that assembler to rebuild it without the
20 $! "const=" definition. Failure to do this will result in an assembler
21 $! that will mung floating point constants.
23 $! Note: The version of gas shipped on the GCC VMS tapes has been patched
24 $! to fix the above mentioned bug.
