10 | $! Command file to build a GNU assembler on VMS | |
11 | $! | |
12 | $! If you are using a version of GCC that supports global constants | |
13 | $! you should remove the define="const=" from the gcc lines. | |
14 | $! | |
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. | |
22 | $! | |
23 | $! Note: The version of gas shipped on the GCC VMS tapes has been patched | |
24 | $! to fix the above mentioned bug. | |
